I. Overview:

1. The BL702 is a highly integrated BLE and Zigbee combo chip for IoT applications.

2. The BL702 wireless subsystem includes 2.4G radio, BLE + zigbee baseband and MAC design. The micro-controller subsystem contains 32-bit RISC CPUs, caches and memory. The power management unit controls the ultra-low power consumption mode. In addition, various security functions are also supported. Its peripheral interface is very rich, including I2C, SPI, ADC, GPIO, PWM, KeyScan, which is convenient for developers to debug and use.

II. Program display:

Function description:

* Support Bluetooth specification version 5.0

* Support internal 32.768KHz RTC clock for more cost-saving

* Support built-in power management unit, no plug-in power chip required

* Support internal RTC clock wake-up and external interrupt wake-up to achieve low-power sleep wake-up mechanism

* Support plug-in embedded PSRAM

* Support a variety of peripherals, such as ADC, PWM, GPIO, I2C,URAT, KEYSCAN

* Support AES 128/192/256-bit encryption engine

III. Application area:

Bluetooth Smart Light Control, Bluetooth Smart Lock, Smart Remote Control, Turn off Bluetooth, It can be used as a single-chip microcomputer.
