A6133M4 is a high performance and low cost 5.8GHz SoC. It integrates M4F micro controller, 512KBytes flash memory, 80KBytes SRAM, USB 2.0 compatible controller and various powerful functions.
A6133M4 supports fast PLL settling time for frequency hopping system. For packet handling, A6133M4 has built-in separated 1K 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, A6133M4 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 QFN7x7 56 pins package.
