                               藍(lán)牙低能量(BLE)的系統(tǒng)芯片--CMT4501

一　產(chǎn)品介紹
CMT4501 is a System on Chip (SoC) for Bluetooth? low energy applications. CMT4501 has 32-bit ARM? Cortex?-M0 CPU with 138KSRAM/Retention SRAM and an ultra-low power, high performance, multi-mode radio. CMT4501 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.
