E-mail: tech_sup@rfm.com DR-WLS1273L-102 Data Sheet - 12/13/12 WLAN SDIO Transport Layer SDIO is the WLAN host interface in the DR-WLS1273L-102. This interface is a standard SDIO interface (SDIO spec Version 2.0). The DR-WLS1273L-102 SDIO also supports the following features: • 4-bit data bus • Functions number 0 and 2 • Multi-Block data transfer • The SDIO interface is used for WLAN. The WLAN block uses function 2. Function 0 is used for the common I/O area. WLAN MAC The DR-WLS1273L-102 MAC implements the IEEE standard 802.11 MAC sub-layer using both dedicated hardware and embedded firmware. The MAC hardware implements real-time functions, including access protocol management, encryption and decryption. WLAN Baseband Processor The DR-WLS1273L-102 baseband processor sits between the on-chip MAC and the radio. The DR-WLS1273L-102 baseband processor implements the IEEE 802.11a/b/g/n PHY sub-layers and has been optimized to perform well in conditions of high multipath and noise. WLAN RF Radio The DR-WLS1273L-102 radio is a highly integrated Digital Radio Processor (DRP) designed for 802.11a/b/g/n applications. The DR-WLS1273L-102 RF interfaces are designed for direct, “glueless” con-nection to single-band RF front ends for 2.4 and 5.8 GHz 802.11a/b/g/n applications. BT Functional Blocks The DR-WLS1273L-102 BT architecture comprises a digital radio processor and a point-to-multipoint baseband core function. The architecture is based on a single-processor ARM core. The device includes on-chip peripherals to enable easy communication between a host system and the Bluetooth core func-tion. BT HCI UART Transport Layers The DR-WLS1273L-102 incorporates one UART module dedicated to the Host Controller Interface (HCI) transport layer. The HCI interface is used to transport commands, events, ACL and data between the Bluetooth device and its host using HCI data packets. The DR-WLS1273L-102 supports the following HCI transport layers, detected automatically when communication starts: • UART transport layer - HCI four-wire (H4) and HCI three-wire (H5) • HCI interface has a 256 byte receive buffer The HCI UART supports most baud rates (including all PC rates) for all fast-clock frequencies - up to a maximum of 4 Mbps. After power-up, the baud rate is set for 115.2 kbps. The maximum baud rate devia-tion supported is -2.5%, +1.5%. The baud rate can thereafter be changed with a VS command. The DR-WLS1273L-102 responds with a Command Complete Event (still at 115.2 kbps), after which the baud rate change takes place. The only parameter needed is the desired baud rate. HCI hardware includes the fol-lowing features:

E-mail: tech_sup@rfm.com DR-WLS1273L-102 Data Sheet - 12/13/12 • Receiver detection of break, idle, framing, FIFO overflow, and parity error conditions • Transmitter underflow detection • CTR/RTS hardware flow control BT UART 4-Wire Interface - H4 The interface includes four signals: TXD, RXD, CTS and RTS. Flow control between the host and the DR-WLS1273L-102 is byte-wise by hardware. Flow control is obtained by the following: H O S T _ R XH O S T T XH O S T _ C T SH O S T _ R T SH C I _ R XH C I _ T XH C I _ C T SH C I _ R T SH o s tP r o c e s s o r D R - W L S 1 2 7 3 L - 1 0 2 When the UART RX buffer asses the “flow control” threshold, it sets the UART_RTS signal high to stop transmission from the host. When the UART_CTS signal is set high, the DR-WLS1273L-102 stops trans-mitting on the interface. In case HCI_CTS is set high in the middle of transmitting a byte, the DR-WLS1273L-102 finishes transmitting the byte and stops the transmission. BT UART 3-Wire Interface - H5 This interface consists of three signals: TXD, RXD and GND: HCI_RX Receive Data on the UART Interface HCI_TX Transmit Data on the UART Interface GND Ground XON/XOFF software flow control is normally used. The DR-WLS1273L-102 also supports a four-wire mode for H5, with RTS/CTS hardware flow control. Since the same UART module is used for the 3- and 4-wire HCI UART interface, all features supported by the 4-wire interface are also supported for the 3-wire interface. H5 features: • Flow control configured with HCI_VS command, software XON/XOFF, hardware (RTS/CTS), or none • Power management • Configurable timers for re-transmission management • CRC

E-mail: tech_sup@rfm.com DR-WLS1273L-102 Data Sheet - 12/13/12 BT Audio CODEC Interface The CODEC interface is a fully dedicated programmable serial port that provides the logic to interface to several kinds of PCM codecs. The interface supports: • Two voice channels • Master/slave modes • Coding schemes: μ-Law, A-Law, Linear, Transparent • Long & short frames • Different data lengths, orders and positions • UDI profile • High rate PCM interface for EDR • Enlarged interface options to support a wider variety of codecs • PCM bus sharing PCM Hardware Interface The PCM interface is one implementation of the codec interface. It contains the following four lines: • Clock - configurable direction (input or output) • Frame Sync - configurable direction (input or output) • Data In - Input • Data Out - Output/Hi-Z The DR-WLS1273L-102 device can be either the master of the interface where it generates the clock and the frame-sync signals, or slave where it receives these two signals. The PCM interface is fully configured by means of a VS command. For slave mode, clock input frequencies of up to 16 MHz are supported. At clock rates above 12 MHz, the maximum data burst size is 32 bits. For master mode, the DR-WLS1273L-102 can generate any clock frequency between 64 kHz and 4.096 MHz. Data Format The data format is fully configurable: • The data length can be from 8 to 320 bits, in 1-bit increments, when working with two channels, or up to 640 bits when using 1 channel. The data length can be set independently for each channel. • The data position within a frame is also configurable with 1-clock (bit) resolution, and can be set inde-pendently (relative to the edge of the Frame Sync signal) for each channel. • The Data_In and Data_Out bit order can be configured independently. For example; Data_In can start with MSB while Data_Out starts with LSB. Each channel is separately configurable. The inverse bit order (i.e. LSB first) is supported only for sample sizes up to 24 bits. • The data in and data out size do not necessarily have to be the same length. • The Data_Out line is configured as a ‘high-Z’ output between data words. Data_Out can also be set for permanent high-Z, irrespective of data out. This allows the DR-WLS1273L-102 to be a bus slave in a mul-ti-slave PCM environment. At power up, Data_Out is configured as high-Z. Frame-Idle Period The CODEC interface has the capability for frame-idle periods, where the PCM clock can “take a break” and become ‘0’ at the end of the PCM frame, after all data has been transferred. The DR-WLS1273L-102 supports frame-idle periods both as master and slave of the PCM bus. When DR-WLS1273L-102 is the master of the interface, the frame-idle period is configurable. There are 2 configurable parameters: • Clk_Idle_Start - indicates the number of PCM clock cycles from the beginning of the frame till the begin-ning of the idle period. After Clk_Idle_Start clock cycles, the clock becomes ‘0’.

E-mail: tech_sup@rfm.com DR-WLS1273L-102 Data Sheet - 12/13/12 • Clk_Idle_End - indicates the time from the beginning of the frame till the end of the idle period. This time is given in multiples of PCM clock periods. The delta between Clk_Idle_Start and Clk_Idle_End is the clock idle period, e.g., for PCM clock rate = 1 MHz, frame sync period = 10 kHz, Clk_Idle_Start = 60, Clk_Idle_End = 90. Between each two-frame sync there are 70 clock cycles (instead of 100). The clock idle period starts 60 clock cycles after the beginning of the frame and lasts 90-60=30 clock cycles. This means that the idle period ends 100-90=10 clock cycles before the end of the frame. The data transmis-sion must end prior to the beginning of the idle period. Audio Encoding The DR-WLS1273L-102 CODEC interface can use one of four audio coding patterns: • A-Law (8-bit) • m-Law (8-bit) • Linear (8 or 16-bit) • Transparent

The default state of the WLAN_IRQ prior to firmware initialization is 0. 2. During firmware initialization, the WLAN_IRQ is configured by the SDIO module; a WLAN_IRQ changes its state to 1 3. A WLAN firmware interrupt is handled as follows: (a) The WLAN firmware creates an Interrupt-to-Host, indicated by a 1-to-0 transition on the WLAN_IRQ line (host must be configured as active-low or falling-edge detect). (b) After the host is available, depending on the interrupt priority and other host tasks, it masks the firmware interrupt. The WLAN_IRQ line returns to 1 (0-to-1 transition on the WLAN_IRQ line). (c) The host reads the internal register status to determine the interrupt sources - the register is cleared after the read (d) The host processes in sequence all the interrupts read from this register (e) The host unmasks the firmware interrupts. 4. The host is ready to receive another interrupt from the WLAN device. DR-WLS1273L-102 BT Function Low Power Mode Protocols The DR-WLS1273L-102 includes a mechanism that handles the transition between operating mode and deep sleep low-power mode. The protocol is done via the UART and is known as eHCILL (enhanced HCI Low Level) power management protocol. This protocol is backward compatible with the BRF6150/BRF6300 /BRF6350/WL1273 HCILL Protocol, so a Host that implements the HCILL for BRF6150/BRF6350 does not need to change anything in order to work with the DR-WLS1273L-102. The "Enhanced" portion of the HCILL introduces changes that allow a simpler host implementation of this pro-tocol. See BT-SW-0024 (BRF Enhanced HCILL 4 wire Power Management Protocol). In addition to the HCILL protocol, the DR-WLS1273L-102 also supports the power management schemes inherent in the UART H5 transport layers.

Packing materials can be deformed at temperatures above 40 C. If the product is not used six months or more after receipt, its solderbility should be tested before being used. The product should be stored in non-corrosive gas. Any excess mechanical shock such as sticking the packing materials with a sharp object or dropping the product, etc., must be avoided in order not to damage the packing materials. This product is applicable to MSL3, based on JEDEC Standard J-STD-020. After the packing is opened, the product should be stored at an ambient temperature below 30 C and at humidity level less than 60% RH. The product should be used within 168 hours. If the color of the indica-tor in the packing has changed, the product should be baked before soldering at 125 to 130 C for 24 hours. The products should be baked on the heat-resistant tray, as the tape and reel materials are not heat-resistant. Handling Conditions Use care in handling or transporting this product as excessive stress or mechanical shock can crack or break the product. Do not touch this product with bare hands as this can result in poor solderability. Standard PCB Design (Land Pattern and Dimensions) All the ground terminals should be connected to the ground patterns, and unconnected terminals should be soldered to unconnected PCB pads for mechanical strength. The best land pattern depends on the pattern generation method, grounding method, land dimensions, land forming method of the unconnected terminals and the PCB material and thickness. Contact RFM technical support if you have any questions about adapting the recommend land pattern to your application specifics or before using non-standard land dimensions, etc. Module PCB Placement This product can be broken by uneven forces from a worn-out chucking locating claw or a suction nozzle. To prevent damage, be sure to follow the specifications for the maintenance of the chip placer being used. Be aware that mechanical chucking can damage this product when used for mounting it on a PCB. Module Soldering Preheat so that the temperature difference T between the solder and module surface is less than 130 C. If the module is immersed in solvent after mounting, care should be taken to limit the temperature difference to 100 C. These provisions are necessary to prevent damage due to excessive differential ex-pansion. Contact RFM technical support if you have any questions about soldering methods or are con-sidering other soldering conditions.
