Overview
CH583 is a 32-bit RISC microcontroller integrated with BLE wireless communication. The chip integrates a 2Mbps low-power Bluetooth BLE communication module, 2 full-speed USB host and device controllers and transceivers, 2 SPIs, 4 serial ports, ADC, touch button detection module, RTC and other rich peripheral resources.
Compared with CH582, CH583 has an additional SP11 host and supports a minimum power supply voltage of 1. 7V. CH581 is simplified based on CH582, removing a
set of USB, touch button detection module, 12C module and two serial ports. The total capacity of FlashROM is only 256KB, and the ADC does not support DMA.
