When configured as input, each I/O port can also be configured with internal pull-up, pull-down or tri-state. Pull-down or  pull-up can only be configured to whole port,  not  individual  pins.  Unused  I/O  pins  should  have  defined  level  and  not  be  floating.  See  the  BLE Configuration Guide for more information about the configuration.  During reset the I/O pins are configured as inputs with pull-ups.  Note: Pins configured as peripheral I/O signals do not have pull-up / -down capability 2.1.2 Reserved I/O’s The high current driving pins P1_0 and P1_1 are reserved for the internal RF front end control. These pins are not exposed in BLE121LR and they can’t be used for application purposes.  P1_7 is also used for the RF front end control but as an output it can be used to control the external DCDC for lowering the peak current drawn from the battery. The function of P1_7 can’t be altered. If external DCD is not used then P1_7 should be left not connected.  2.2  UART UART  baud  rate  can  be  configured  up  2  Mbps.

  Bluegiga Technologies Oy Page 19 of 31 5  Power-On Reset and Brownout Detector BLE121LR includes a power-on reset (POR), providing correct initialization during device power on. It  also includes  a  brownout  detector  (BOD)  operating  on  the  regulated  1.8-V  digital  power  supply only. The  BOD protects the memory contents during supply voltage variations which cause the regulated 1.8-V power to drop below the minimum level required by digital logic, flash memory, and SRAM. When power is initially applied, the POR and BOD hold the device in the reset state until the supply voltage rises above the power-on-reset and brownout voltages.
  Bluegiga Technologies Oy Page 20 of 31 6  Design Guidelines 6.1  General Design Guidelines BLE121LR can be used directly with a coin cell battery. Due to relatively high internal resistance of a coin cell battery it is recommended to place a 100uF capacitor in parallel with the battery. The internal resistance of a coin cell battery is initially in the range of 10 ohms but the resistance increases rapidly as the capacity is used. Basically the higher the value of the capacitor the higher is the effective capacity of the battery and thus the longer the life time for the application. The minimum value for the capacitor depends on the end application and the maximum transmit power used. The leakage current of a 100uF capacitor is in the range of 0.5 uA to 3  uA  and  generally  ceramic  capacitors  have  lower  leakage  current  than  tantalum  or  aluminum  electrolytic capacitors.  Optionally TI’s TPS62730 can be used to reduce the current consumption during TX/RX and data processing stages.  TPS62730  is  an  ultra-low  power  DC/DC  converter  with  by-pass  mode  and  will  reduce  the  current consumption during transmission nominally by ~20% when using 3V coin cell battery.      Figure 16: Example schematic for BLE121LR with a coin cell battery, TPS62730 DCDC converter and an I2C accelerometer  6.2  Layout Guide Lines Use  good  layout  practices  to  avoid  excessive  noise  coupling  to  supply  voltage  traces  or  sensitive  analog signal traces. If using overlapping ground planes use stitching vias separated by max 3 mm to avoid emission from the edges of the PCB. Connect all the GND pins directly to a solid GND plane and make sure that there is a low impedance path for the return current following the signal and supply traces all the way from start to the end.  A good practice is to dedicate one of the inner layers to a solid GND plane and one of the inner layers to supply  voltage  planes  and  traces  and  route  all  the  signals  on  top  and  bottom  layers  of  the  PCB.  This
  Bluegiga Technologies Oy Page 21 of 31 arrangement will make sure that any return current follows the forward current as close as possible and any loops are minimized.   Layout•Supply voltage–If possible use solid power plane–Make sure that solid GND plane follows the traces all the way–Do not route supply voltage traces across separated GND regions so that the path for the return current is cut•MIC input–Place LC filtering and DC coupling capacitors symmetrically as close to audio pins as possible–Place MIC biasing resistors symmetrically as close to microhone as possible.–Make sure that the bias trace does not cross separated GND regions (DGND -> AGND) so that the path for the return current is cut. If this is not possible the do not separate GND regions but keep one solid GND plane.–Keep the trace as short as possibleSignalsGNDPowerSignalsRecommended PCB layer configuration Figure 17: Typical 4-layer PCB construction  Overlapping GND layers without GND stitching vias Overlapping GND layers with GND stitching vias shielding the RF energy Figure 18: Use of stitching vias to avoid emissions from the edges of the PCB  6.3  BLE121LR-A Layout Guide For optimal performance of the antenna place the module at the edge of the PCB as shown in the Figure 19. Do not place any metal (traces, components, battery etc.) within the clearance area of the antenna. Connect all the GND pins directly to a solid GND plane. Place the GND vias as close to the GND pins as possible. Use good layout practices  to  avoid  any excessive noise coupling to signal lines or  supply voltage  lines.

  Bluegiga Technologies Oy Page 23 of 31 7  Soldering Recommendations BLE121LR is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent  on  the  thermal  mass  of  the  entire  populated  PCB,  heat  transfer  efficiency  of  the  oven  and particular type of solder paste used. Consult the datasheet of particular solder paste for profile configurations.  Bluegiga Technologies will give following recommendations for soldering the module to ensure reliable solder joint and operation of the module after soldering. Since the profile used is process and layout dependent, the optimum  profile  should  be  studied  case  by  case.  Thus  following  recommendation  should  be  taken  as  a starting point guide.  -  Refer to technical documentations of particular solder paste for profile configurations -  Avoid using more than one flow.  -  Reliability of the solder joint and self-alignment of the component are dependent on the solder volume. Minimum of 150m stencil thickness is recommended.  -  Aperture size of the stencil should be 1:1 with the pad size.  - A low residue, “no clean” solder paste should be used due to low mounted height of the component.

  Bluegiga Technologies Oy Page 24 of 31 8  Block diagram BLE121LR is  based  on  TI’s  CC2541 chip.  Embedded 32  MHz  and 32.678 kHz  crystals  are  used for clock generation.

It has three different memory access buses (SFR, DATA, and CODE/XDATA), a debug interface, and an 18-input extended interrupt unit. The memory arbiter is at the heart of the system, as it connects the CPU and DMA controller with the physical memories  and  all  peripherals  through  the  SFR  bus.  The  memory  arbiter  has  four  memory-access  points, access  of  which  can  map  to  one  of  three  physical  memories:  an  SRAM,  flash  memory,  and  XREG/SFR registers. It is responsible for performing arbitration and sequencing between simultaneous memory accesses to the same physical memory. The SFR bus is a common bus that connects all hardware peripherals to the memory arbiter. The SFR bus also provides access to the radio registers in the radio register bank, even though these are indeed mapped into XDATA memory space. The 8-KB SRAM maps to the DATA memory space and to parts of the XDATA memory spaces. The SRAM is an ultralow-power SRAM that retains its contents even when the digital part is powered off (power modes 2 and 3). The 256 KB flash block  provides in-circuit programmable non-volatile program memory for the device, and maps into the CODE and XDATA memory spaces. Peripherals Writing to the flash block is performed through a flash controller that allows page-wise erasure and 4-bytewise programming.  A  versatile  five-channel  DMA  controller  is  available  in  the  system,  accesses  memory  using  the  XDATA memory space, and thus has access to all physical memories. Each channel (trigger, priority, transfer mode,
  Bluegiga Technologies Oy Page 25 of 31 addressing mode, source and destination pointers, and transfer count) is configured with DMA descriptors that can be located anywhere in memory. Many of the hardware peripherals (AES core, flash controller, USARTs, timers, ADC  interface,  etc.)  can  be used with  the DMA controller  for  efficient operation by performing  data transfers between a single SFR or XREG address and flash/SRAM. Each CC2541 contains a unique 48-bit IEEE address that can be used as the public device address for a Bluetooth device. Designers are free to use this address, or provide their own, as described in the Bluetooth specification. The interrupt controller services a total of 18 interrupt sources, divided into six interrupt groups, each of which is associated with one of four interrupt priorities. I/O and sleep timer interrupt requests are serviced even if the device is in a sleep mode (power modes 1 and 2) by bringing the CC2541 back to the active mode. The debug interface implements a proprietary two-wire serial interface that is used for in-circuit debugging. Through  this  debug  interface,  it  is  possible  to  erase  or  program  the  entire  flash  memory,  control  which oscillators are enabled, stop and start execution of the user program, execute instructions on the 8051 core, set code breakpoints, and single-step through instructions in the code. Using these techniques, it is possible to perform in-circuit debugging and external flash programming elegantly. The I/O controller is responsible for all general-purpose I/O pins. The CPU can configure whether peripheral modules  control  certain  pins  or  whether  they  are  under  software  control,  and  if  so,  whether  each  pin  is configured as an input or output and if a pullup or pulldown resistor in the pad is connected. Each peripheral that connects to the I/O pins can choose between two different I/O pin locations to ensure flexibility in various applications. The sleep timer is an ultra-low power timer that uses an external 32.768-kHz crystal oscillator. The sleep timer runs continuously in all operating modes except power mode 3. Typical applications of this timer are as a real-time counter or as a wake-up timer to exit power modes 1 or 2. Timer  1  is  a  16-bit  timer  with  timer/counter/PWM  functionality.  It  has  a  programmable  prescaler,  a  16-bit period value, and five individually programmable counter/capture channels, each with a 16-bit compare value. Each of the counter/capture channels can be used as a PWM output or to capture the timing of edges on input signals. It can also be configured in IR generation mode, where it counts timer 3 periods and the output is ANDed with the output of timer 3 to generate modulated consumer IR signals with minimal CPU interaction. Timer 2 is a 40-bit timer used by the Bluetooth low energy stack. It has a 16-bit counter with a configurable timer period and a 24-bit overflow counter that can be used to keep track of the number of periods that have transpired. A 40-bit capture register is also used to record the exact time at which a start-of-frame delimiter is received/transmitted  or  the  exact  time  at  which  transmission  ends.  There  are  two  16-bit  timer-compare registers and two 24-bit overflow-compare registers that can be used to give exact timing for start of RX or TX to the radio or general interrupts. Timer  3  and  timer  4  are  8-bit  timers  with  timer/counter/PWM  functionality.  They  have  a  programmable prescaler, an 8-bit period value, and one programmable counter channel with an 8-bit compare value. Each of the counter channels can be used as PWM output. USART 0 and USART 1 are each configurable as either an SPI master/slave or a UART. They provide double buffering on both RX and TX and hardware flow control and are thus well suited to high-throughput full-duplex applications. Each USART  has its own high-precision baud-rate generator, thus leaving the ordinary timers free for other uses. When configured as SPI slaves, the USARTs sample the input signal using SCK directly instead of using some oversampling scheme, and are thus well-suited for high data rates. The AES encryption/decryption core allows the user to encrypt and decrypt data using the AES algorithm with 128-bit keys. The AES core also supports ECB, CBC, CFB, OFB, CTR, and CBC-MAC, as well as hardware support for CCM. The ADC supports 7 to 12 bits of resolution with a corresponding range of bandwidths from 30-kHz to 4-kHz, respectively. DC and audio conversions with up to eight input channels (I/O controller pins) are possible. The inputs  can  be  selected  as  single-ended  or  differential.  The  reference  voltage  can  be  internal,  AVDD,  or  a single-ended or differential external signal. The ADC also has a temperature-sensor input channel. The ADC can automate the process of periodic sampling or conversion over a sequence of channels. The I2C module provides a digital peripheral connection with two pins and supports both master and slave
  Bluegiga Technologies Oy Page 26 of 31 operation. I2C support is compliant with the NXP I2C specification version 2.1 and supports standard mode (up to 100 kbps) and fast mode (up to 400 kbps). In addition, 7-bit device addressing modes are supported, as well as master and slave modes.. The ultralow-power analog comparator enables applications to wake up from PM2 or PM3 based on an analog signal. Both inputs are brought out to pins; the reference voltage must be provided externally. The comparator output is connected to the I/O controller interrupt detector and can be treated by the MCU as a regular I/O pin interrupt. RF front end RF front end includes balun, power amplifier, low noise amplifier, band pass filter, and a ceramic chip antenna with matching network. Optimal matching combined with effective low pass filter provides extremely low in-band spurious emissions and harmonics.

IC Statements:  This  device  complies  with  Industry  Canada  licence-exempt  RSS  standard(s).  Operation  is  subject  to  the following  two  conditions:  (1)  this  device  may  not  cause  interference,  and  (2)  this  device  must  accept  any interference, including interference that may cause undesired operation of the device. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum  (or  lesser)  gain  approved  for  the  transmitter  by  Industry  Canada.  To  reduce  potential  radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.  OEM Responsibilities to comply with FCC and Industry Canada Regulations The  BLE121LR  module has  been  certified  for  integration  into  products  only by  OEM  integrators  under  the following condition:    The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures.  As  long  as  the  condition  above  is  met,  further  transmitter  testing  will  not  be  required.  However,  the  OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
  Bluegiga Technologies Oy Page 28 of 31  IMPORTANT NOTE: In the event that the above condition can not be met (for certain configurations or co-location with another transmitter), then the FCC and Industry Canada authorizations are no longer considered valid  and  the  FCC  ID  and  IC  Certification  Number  can  not  be  used  on  the  final  product.  In  these circumstances,  the  OEM  integrator  will  be  responsible  for  re-evaluating  the  end  product  (including  the transmitter) and obtaining a separate FCC and Industry Canada authorization.  End Product Labeling The BLE121LR module is labeled with its own FCC ID and IC Certification  Number. If the FCC ID and IC Certification Number are not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module.  In that case, the final end product must be labeled in a visible area with the following:   “Contains Transmitter Module FCC ID: QOQBLE121LR” “Contains Transmitter Module IC: 5123A-BGTBLE121LR” or  “Contains FCC ID: QOQBLE121LR” “Contains IC: 5123A-BGTBLE121LR”   The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module or change RF related parameters in the user manual of the end product.  9.2.1 FCC et IC Déclaration d’IC :  Ce dispositif est conforme aux normes RSS exemptes de licence d’Industrie Canada. Son fonctionnement est assujetti  aux  deux  conditions  suivantes :  (1)  ce  dispositif  ne  doit  pas  provoquer  de  perturbation  et  (2)  ce dispositif doit accepter toute perturbation, y compris les perturbations qui peuvent entraîner un fonctionnement non désiré du dispositif. Selon  les  réglementations  d’Industrie  Canada,  cet  émetteur  radio  ne  doit  fonctionner  qu’avec  une  antenne d’une  typologie  spécifique  et  d’un  gain  maximum  (ou  inférieur)  approuvé  pour  l’émetteur  par  Industrie Canada. Pour réduire les éventuelles perturbations  radioélectriques  nuisibles  à  d’autres  utilisateurs,  le  type d’antenne et son gain doivent être choisis de manière à ce que la puissance  isotrope rayonnée équivalente (P.I.R.E.) n’excède pas les valeurs nécessaires pour obtenir une communication convenable.  Responsabilités  des  OEM  quant  à  la  conformité  avec  les  réglementations  de  FCC  et  d’Industrie Canada Les modules BLE121LR ont été certifiés pour entrer dans la fabrication de produits exclusivement réalisés par des intégrateurs dans les conditions suivantes :  Le module transmetteur ne doit pas être installé ou utilisé en concomitance avec une autre antenne ou un autre transmetteur. Tant que ces deux conditions sont réunies, il n’est pas nécessaire de procéder à des tests supplémentaires sur le transmetteur. Cependant, l’intégrateur est responsable des tests effectués sur le produit final afin de se
  Bluegiga Technologies Oy Page 29 of 31 mettre en conformité avec d’éventuelles exigences complémentaires lorsque le module est installé (exemple : émissions provenant d’appareils numériques, exigences vis-à-vis de périphériques informatiques, etc.)   REMARQUE  IMPORTANTE :  En  cas  d’inobservance  de  ces  conditions  (en  ce  qui  concerne  certaines configurations  ou  l’emplacement  du  dispositif  à  proximité  d’un  autre  émetteur),  les  autorisations  de  FCC et d’Industrie Canada ne seront plus considérées valables et l’identification de FCC et le numéro de certification d’IC ne pourront pas être utilisés sur le produit final. Dans ces cas, l’intégrateur OEM sera chargé d’évaluer à nouveau  le  produit  final  (y  compris  l’émetteur)  et  d’obtenir  une  autorisation  indépendante  de  FCC  et d’Industrie Canada.  Étiquetage du produit final Le module BLE121LR est étiqueté avec sa propre identification FCC et son propre numéro de certification IC. Si  l’identification  FCC et  le numéro de certification IC ne sont pas visibles  lorsque le module est installé à l’intérieur  d’un  autre  dispositif,  la  partie  externe  du  dispositif  dans  lequel  le  module  est  installé  devra également présenter une étiquette faisant référence au module inclus. Dans ce cas, le produit final devra être étiqueté sur une zone visible avec les informations suivantes :  « Contient module émetteur identification FCC : QOQBLE121LR » « Contient module émetteur IC : 5123A-BGTBLE121LR » ou  « Contient identification FCC : QOQBLE121LR » « Contient IC : 5123A-BGTBLE121LR »  Dans  le  guide  d’utilisation  du  produit  final,  l’intégrateur  OEM  doit  s’abstenir  de  fournir  des  informations  à l’utilisateur final portant sur les procédures à suivre pour installer ou retirer ce module RF ou pour changer les paramètres RF. .
