Selection Guide
| General Description |
|
A8108 is a low cost 2.4GHz ISM SoC. In the RF part, this device integrates both high sensitivity receiver and a programmable high efficiency power amplifier. It also integrates high speed pipeline 8051 MCU, 32KBytes In-system programmable flash memory, 256B internal SRAM, 512B external SRAM, USB 2.0 compatible controller and various powerful functions. A8108 supports fast PLL settling time for frequency hopping system. For packet handling, A8108 has built-in auto-ack and auto-resend, CRC for error packet filtering, RSSI for clear channel assessment, thermal sensor to monitor 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. A8108 supports AES128 engine and CCM. Those functions are very easy to use while developing a wireless system. |
