CMT4552

蓝牙5.2 SoC芯片

CMT4552 is a System on Chip (SoC) for Bluetooth 5.2 applications. It has high-performance low-power 32-bit processer with 64K retention SRAM, 512/256KB flash, 96KB ROM, 256bit efuse, and an ultra-low power, high performance, multi-mode radio. Also, CMT4552 can support BLE with security, application and over-the-air download update. Serial peripheral IO and integrated application IP enables customer product to be built with minimum bill-of-material (BOM) cost.
