HOPERF Bluetooth 5.2 / IEEE 802.15.4 System on Chip CMT4522

Description:

CMT4522 is a System on Chip (SoC) for Bluetooth 5.2 / IEEE 802.15.4 applications. It has ARM? Cortex?- M0 32-bit processer with 64K retention SRAM, 128KB-8MB flash, 96KB ROM, 256bit efuse, and an ultralow power, high performance, multi-mode radio. Also, CMT4522 can support BLE / IEEE 802.15.4 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.
