GENERAL DESCRIPTION
A8105 is a high performance and low cost 2.4GHz FSK/GFSK system-on-chip (SOC) wireless transceiver. With on chip fraction-N synthesizer, it can support the application of data rate from 4Kbps to 2Mbps and frequency hopping system. A8105 has various operating modes, making it highly suited for systems where ultra-low power consumption is required. The device is in QFN5X5 40 pin package.
