General Description
A8526 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 5Kbps to 2Mbps and frequency hopping system.
This device integrates high speed pipeline 8051 MCU, 16KBytes In-system programmable flash memory, 256Bytes internal data RAM, 2KBytes external data RAM, various powerful functions and excellent performance of a leading 2.4GHz FSK/GFSK RF transceiver.
A8526 has various operating modes, making it highly suited for systems where ultra-low power consumption is required.
A8526 has 4 X 48 segments LCD driver to support LCD display and also built-in RC type ADC converter.
