The SMC52300 BLE module, which built in a RTL8762AG BLE chip, is an ultra-low power system on chip solution for BLE low energy applications. The SMC52300 combines the excellent performance of a leading RF transceiver with ARM Cortex M0, 256KB eflash, 80KB RAM, and rich powerful supporting features and peripherals. The SMC52300 embeds IR transceiver, hardware keyscan, and Quad-decoder on the module.
