A8525
Selection Guide
| General Description |
| A8525 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. A8525 has various operating modes, making it highly suited for systems where ultra-low power consumption is required. A8525 has 4 X 48 segments LCD driver to support LCD display. |
