PHY6252 — Ultra Cost-Effective Bluetooth 5.2 / 2.4G SoC

The PHY6252 is a high-performance, ultra-low-power Bluetooth 5.2 SoC built around a 32-bit processor. It offers 64 KB retention SRAM, 512/256 KB Flash, 96 KB ROM, 256-bit eFuse, and supports secure OTA updates. With rich peripherals and integrated application IP, it enables full-featured products with the lowest possible BOM.

Ideal for wearables, beacons, smart home/building, health/medical, industrial, retail/payment, data transmission, PC/mobile/TV peripherals, and general IoT.
