Selection Guide
General Description
A7196 is a high data rate (up to 6Mbps) and low cost 2.4GHz ISM band transceiver.
A7196 supports fast PLL settling time for frequency hopping system. For packet handling, A7196 has built-in separated (512 bytes) TX/RX FIFO for data buffering and burst transmission, auto-ack and auto-resend, CRC for error packet filtering, FEC (7,4 hamming code) for 1-bit data correction per code word, RSSI for clear channel assessment, thermal sensor to monitor relative temperature, data whitening for data encryption / decryption. In addition, A7196 has built-in AES128 co-processor (Advanced Encryption Standard) for advanced data encryption or decryption which consists of the transformation of a 128-bit block into an encrypted 128-bit block. Those functions are very easy to use while developing a wireless system. All features are integrated in a small QFN 4X4 24 pins package.

A7196’s control registers are accessed via 3-wire or 4-wire SPI interface such as TX/RF FIFO, ID register, RSSI value, frequency hopping and calibration procedures. Another one is the unique Strobe command via SPI to control power saving mode (sleep, idle, standby), TX mode and RX mode. The other connections between A7196 and MCU are GIO1 and GIO2 (multi-function GPIO) to output A7196’s status so that MCU could use either polling or interrupt scheme for radio control. Overall, it is very easy to develop a wireless application by a MCU and A7196 because of its rich and easy-to-use features.
