1 Overview

SPB209A-EVK is a complete WLAN/BT/NFC module with EMC shield, dual band antenna (WiFi and BT), prepared for application specific NFC antenna and ready for quick validation in a hosted environment. SPB209A-EVK features the SPB209A module mounted on a ready to run SD-card or SMD module for quick product turn-around or SPB209A evaluation. It provides an ultra-low power, high performance and feature rich client solution. It provides up to 433 Mbit/s data rate when operating in the OFDM mode and up to 11 Mbit/s data rate when operating in the DSSS/CCK mode.

SPB209A integrates RF, baseband/MAC, Bluetooth Package Engine, NFC, memory, RF filters, oscillator, antenna or SMA connector and EMC shield into a highly integrated and optimized module solution with high quality and reliability to a complete standalone solution with no need for external components.

This highly integrated solution is optimized for customer applications running on a Linux host platform. The host interface supports SDIO 3.0, High Speed UART and I2C. Internal RAM comprises both code and data memory eliminating the need for external RAM, Flash or ROM memory interfaces. MAC address, trimming values etc. are stored in the on board memory.

1.1 Key Features

 Support for 802.11a/b/g/n/ac  Data Rates: 20MHz CH 1-86Mbps; 40MHz CH 13-200Mbps; 80MHz CH 29-433Mbps  Modulation: BPSK, CCK, QPSK, 16QAM, 64QAM 256 QAM for WLAN and

GFSK/π/4DQPSK/8DPSK/LE

 Open WEP, WPA/WPA2 encryption

 No external components except for the antenna options  Low power consumption due to efficient PA design and power off mode  An on-board 32 kHz oscillator maintains real time in power save mode, allows the high

frequency clock to be turned off.

 Supporting STA and AP operation mode  Supports BT-WLAN coexistence and ISM-LTE coexistence  Extensive DMA hardware support for data flow to reduce CPU load.  Advanced power management for optimum power consumption at varying load.  External interfaces 4 bit SDIO 3.0 for WLAN and UART/PCM for BT interface  On-board High Frequency High Precision Oscillator 37.4 MHz  Small footprint 14 x 14 mm (196 mm2) 41-pin  RoHS Compliant

2 APPLICATION INFORMATION

2.1 Power Supply

SPB209A should be powered by a single supply voltage on VDD of 3.3V. It generates all required digital and analog supply voltages with the built in DC-DC converter.

2.1.1 Main supply

The main power is connected to VDD. The ripple on VDD should be less than 10mV p-p.

2.2 Clock Signals

The SPB209A requires no external clock signals. It has an internal high frequency oscillator with a high precision 37.4 MHz crystal and a low power oscillator to generate the required clock signals.

2.3 Standby

The Power Down pin (PDn) shall be set high during normal operation of either connectivity type. Pulling PDn pin low, sets SPB209A in Standby mode. This turns OFF most parts of the circuit and minimizes the current consumption. All I/O interface pins are set to predefined states (high, low or high-z) when in Standby mode.

To end Standby mode set PDn high and reload firmware.

2.4 Power save

H&D Wireless AB, SPB209A Application Note page 5 ( 15)

1453- SPB209A Rev B

Power save is an energy saving mode where SPB209A is only listening at regular intervals for the beacons transmitted from an access point and is set in sleep mode in between. During this sleep mode, firmware is kept in RAM but all not needed functions are turned off. Since the receive time is very short compared to the listening interval the average current consumption is reduced significantly. The timing of the listening interval is based on the low power oscillator clock generated internally.

2.5 Interfaces

The SPB209A is equipped with a number of interfaces that can be set up in various ways by the value on GPIO2 and GPIO3 during boot, see section 2.5.1.

2.5.1 Host Interface SDIO and UART

The SDIO interface is SDIO 4-bit mode. For timing characteristics and trigger level see Fel! Hittar inte referenskälla. and Fel! Hittar inte referenskälla., Fel! Hittar inte referenskälla., Fel! Hittar inte referenskälla. and Fel! Hittar inte referenskälla..

The High Speed UART interface default supporting Baud Rates from 1200 up to 2764800 bps, 8 bits, no parity, 1 stop bit.

Booth GPIO2 and GPIO3 have internal pull-up and only needs to be connected via a 100kOhm resistor to GND to be set low (0). For high level (1) the pin can be left unconnected. Table 2-1 shows the different options. The default is to leave GPIO2 and GPIO3 unconnected (11) and SDIO as host interface for all services.

2.5.2 PCM Interface

2.5.3 PCM

PCM interface is used for BT audio and can operate in master or slave mode. The interface supports the following:

- 8, 13, 14, 15 or 16-bit samples

- 4 slots per frame with up to 16-bits per slot

- Long or short frame sync

2.5.4 Host Wake up

Wake up command via the SDIO interface. This is the normal wake up and is implemented in the FW.

There is options to use defined GPIO:s for Host Wake-up or opposite for SPB209A Wake-Up involving both WLAN, BT and NFC. Below table outline the options.
