| General Description |
|
A8125M0 is a high performance and low cost 2.4GHz ISM band FSK/GFSK wireless SoC. It integrates M0 micro controller, 128KBytes flash memory and 32KBytes SRAM. For packet handling, A8125M0 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. In addition, A8125M0 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. For low current consumption, A8125M0 is integrated with both LDO and DC-DC (buck) so that this device can be operated more efficient. User can configure one of them (LDO or DC-DC) as a powered source for device operations. |
