It uses an instruction set called Thumb, which was first supported in the ARM7TDMI processor; however, several newer instructions from the ARMv6 architecture and a few instructions from the Thumb-2 technology are also included. Thumb-2 technology extended the previous Thumb instruction set to allow all operations to be carried out in one CPU state. The instruction set in Thumb-2 includes both 16-bit and 32-bit instructions; most instructions generated by the C compiler use the 16-bit instructions, and the 32-bit instructions are used when the 16-bit version cannot carry out the required operations. This results in high code density and avoids the overhead of switching between two instruction sets. In total, the Cortex-M0 processor supports 56 base instructions, although some instructions can have more than one form. While the instruction set is small, the Cortex-M0 processor is highly capable because the Thumb instruction set is highly optimized. 5.2 BLUETOOTH SMART 5.2.1 BLE Core The BLE (Bluetooth Low Energy) core is a qualified Bluetooth v4.1 baseband controller compatible with Bluetooth Smart specification and it is in charge of packet encoding- decoding and frame scheduling.  Bluetooth Smart Specifications compliant according to the Specification of the Bluetooth System, v4.1, Bluetooth SIG.  All device classes are supported -- Broadcast, Central, Observer, Peripheral)  All packet types (Advertising / Data / Control)  Encryption (AES / CCM)  Bit stream processing (CRC, Whitening)  FDMA / TDMA / events formatting and synchronization  Frequency Hopping calculation  Operating clock with internal 16 MHz  Low power modes with internal 32.678 kHz  Supports power down of the baseband during the protocol’s idle periods.  Advanced High performance Bus (AHB) Slave interface for register file access.  AHB Slave interface for Exchange Memory access of CPU via BLE core.  AHB Master interface for direct access of BLE core to Exchange Memory space

Numerous Bluetooth Smart profiles for consumer wellness, sport, fitness, security and proximity applications are supplied as standard, while additional customer profiles can be developed and added as needed. The SmartSnippetsTM software development environment is based on KeilTM ‘s uVision mature tools and contains example application code for both embedded and hosted modes. 5.2.3 Memory The following memories are part of the PAN1740’s internal blocks: ROM. This is a 84 kB ROM containing the Bluetooth Smart protocol stack as well as the boot code sequence. OTP. This is a 32 kB One-Time Programmable memory array, used to store the application code as well as Bluetooth Smart profiles. It also contains the system configuration and calibration data. System SRAM. This is a 42 kB system SRAM (Sys-RAM) which is primarily used for mirroring the program code from the OTP when the system wakes/powers up. It also serves as Data RAM for intermediate variables and various data that the protocol requires. Optionally, it can be used as extra memory space for the BLE TX and RX data structures. Retention RAMs. These are 4 special low leakage SRAM cells (2 kB + 2 kB + 3 kB + 1 kB) used to store various data of the Bluetooth Smart protocol as well as the system’s global variables and processor stack when the system goes into Deep Sleep mode. Storage of this data ensures secure and quick configuration of the BLE Core after the system wakes up. Every cell can be powered on or off according to the application needs for retention area when in Deep Sleep mode.

Upon completion of development, the application code can be programmed into the OTP. In general, the system has three functional modes of operation: A. Development Mode: During this phase application code is developed using the ARM Cortex M0 SW environment. The compiled code is then downloaded into the System RAM or any Retention RAMs by means of SWD (JTAG) or any serial interface (e.g. UART). Address 0x00 is remapped to the physical memory that contains the code and the CPU is configured to reset and execute code from the remapped device. This mode enables application development, debugging and on-the-fly testing. B. Normal Mode: After the application is completed and verified, the code can be burned into the OTP. When the system boots/wakes up, the DMA of the OTP controller will automatically copy the program code from the OTP into the system RAM. Next, a SW reset will remap address 0x00 to the System RAM and code execution is started. Hence, in this mode, the system is autonomous, contains the required SW in OTP and is ready for integration into the final product. C. Calibration Mode: Programming the Bluetooth device address is completed in Calibration Mode. 5.2.5 Power Modes There are four different power modes in the PAN1740: o Active Mode: System is active and operates at full speed.  Sleep Mode: No power gating has been programmed, the ARM CPU is idle, waiting for an interrupt. PD_SYS is on. PD_PER and PED_RAD depending on the programmed enabled value.  Extended Sleep Mode: All power domains are off except for the PD_AON, the programmed PD_RRx and the PD_SR. Since the SysRAM retains its data, no OTP mirroring is required upon waking up the system.  Deep Sleep Mode: All power domains are off except for the PD_AON and the programmed PD_RRx. This mode dissipates the minimum leakage power. However, since the SysRAM has not retained its data, an OTP mirror action is required upon waking up the system.

Data is written from a master (CPU) over the APB bus to the UART and it is converted to serial form and transmitted to the destination device. Serial data is also received by the UART and stored for the master (CPU) to read back. There is no DMA support on the UART block since its contains internal FIFOs. Both UARTs support hardware flow control signals (RTS, CTS, DTR, DSR). Features  16 bytes Transmit and receive FIFOs.  Hardware flow control support (CTS/RTS)  Shadow registers to reduce software overhead and also include a software programmable reset  Transmitter Holding Register Empty (THRE) interrupt mode  IrDA 1.0 SIR mode supporting low power mode.  Functionality based on the 16550 industry standard:  Programmable character properties, such as number of data bits per character (5-8), optional  parity bit (with odd or even select) and number of stop bits (1, 1.5 or 2)  Line break generation and detection  Prioritized interrupt identification  Programmable serial data baud rate as calculated by the following: baud rate = (serial clock frequency)/(divisor).

This includes a clearly visible label on the outside of the OEM enclosure specifying the appropriate Panasonic FCC identifier for this product as well as the FCC Notice above. The FCC identifier is FCC ID: T7V1740. This FCC identifier is valid for all PAN1740 modules, for details, see the Chapter 28 - Ordering Information. In any case the end product must be labelled exterior with "Contains FCC ID: T7V1740" 38 ANTENNA WARNING For the related part number of PAN1740 refer to Chapter 28 - Ordering Information. This device is tested with a standard SMA connector and with the antennas listed below. When integrated in the OEMs product, these fixed antennas require installation preventing end-users from replacing them with non-approved antennas. Any antenna not in the following table must be tested to comply with FCC Section 15.203 for unique antenna connectors and Section 15.247 for emissions. 39 APPROVED ANTENNA LIST Note: We are able to qualify your antenna and will add to this list as that process is completed. Item Part Number Manufacturer Frequency Band Type Gain (dBi) 1 LDA212G3110K Murata 2.4GHz Chip-Antenna +0.9 40 RF EXPOSURE To comply with FCC RF Exposure requirements, the Original Equipment Manufacturer (OEM) must ensure that the approved antenna in the previous table must be installed. The preceding statement must be included as a CAUTION statement in manuals for products operating with the approved antennas in the previous table to alert users on FCC RF Exposure compliance. Any notification to the end user of installation or removal instructions about the integrated radio module is not allowed. The radiated output power of PAN1740 with mounted ceramic antenna (FCC ID: T7V1740) is far below the FCC radio frequency exposure limits. Nevertheless, the PAN1740 shall be used in such a manner that the potential for human contact during normal operation is minimized. End users may not be provided with the module installation instructions. OEM integrators and end users must be provided with transmitter operating conditions for satisfying RF exposure compliance.
