General Description
A7102C is a high performance and low cost Sub 1GHz ISM band wireless FSK transceiver with programmable 2K ~ 150Kbps data rate. It integrates high sensitivity receiver (-118dBm @2Kbps / - 115 dBm @ 10Kbps for 433.92MHz), high efficiency power amplifier (up to 15 dBm), frantional-N frequency synthesizer and baseband modem. In typical system, A7102C supports both FIFO mode and direct mode. In direct mode, A7102C supports recovery clock (CKO pin) to MCU for data latching.

For packet handling, A7102C has built-in separated 64-bytes TX/RX FIFO for data buffering and burst transmission, CRC error detection, FEC error correction (1-bit data correction per code word), digital RSSI for clear channel assessment, data whitening for payload encryption / decryption, temperature sensor to monitor relative temperature. Those functions are very easy to use while developing a wireless system. All features are integrated in a QFN 5X5 32 pins package.
