PHY6235 – Bluetooth Low Energy and Proprietary 2.4 GHz SoC
Overview
The PHY6235 is a high-performance, low-power SoC for Bluetooth Low Energy (BLE) and proprietary 2.4 GHz applications. It features a 32-bit RISC-V MCU (up to 48 MHz), 8 KB SRAM, 80 KB ROM, 256/512 KB Flash, and a multi-mode radio. With integrated application IP and serial peripheral IO, it supports secure BLE applications with minimal BOM cost.
