Chip introduction

BL602 is a chipset with integrated 2.4G Wi-Fi + BLE 5.0, suitable for low power consumption and high performance application development.

The wireless subsystem supports 2.4G radio, Wi-Fi 802.11b/g/n and BLE 5.0 baseband/MAC design.

The microcontroller subsystem is powered by a 32-bit RISC CPU clocked at up to 192MHz.

Built-in 276KB RAM, 128KB ROM, 1Kb eFuse and configurable embedded Flash. In addition, a variety of security features are supported.

Peripheral interfaces include SDIO, SPI, UART, I2C, IR remote, PWM, ADC, DAC, PIR and GPIO, etc.
