Selection Guide
General Description
A8137M0 is a high performance and low cost 2.4GHz ISM band FSK/GFSK wireless SoC. It integrates M0 micro controller, 64KBytes flash memory, 8KBytes SRAM, Li-Ion battery charger and excellent performance of 2.4GHz RF transceiver.
For packet handling, A8137M0 has built-in separated 64-bytes TX/RX FIFO for data buffering and burst transmission, auto-ack and auto-resend, CRC for error packet filtering, FEC for 1-bit data correction per code word, RSSI for clear channel assessment, thermal sensor for monitoring relative temperature, WOR (Wake on RX) function to support periodically wake up from sleep mode to RX mode and listen for incoming packets without MCU interaction, data whitening for data encryption / decryption. Those functions are very easy to use while developing a wireless system.
