Overview
CH555 is an enhanced E8051 core MCU, compatible with MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions. CH555 features fast run speed, and has built-in 64KB Flash-ROM and 8K+256B RAM. CH555 has a built-in full-speed composite USB Device controller and transceiver. The composite USB device controller is composed of a USB device-hub and 3 sub-devices with HID function. CH555 has built-in 3*8 channels of PWM, supports 384 monochrome LEDs or 128 groups of RGB LEDs. CH555 provides abundant interface sources, including 14-channel 12-bit ADC, 3 timers and 2-channel signal capture, 2 UARTs, SPIs, I2C slave and other functional modules. CH555 has built-in 128 RGB LED controllers and USB Device, which can be used for customized mechanical keyboard design.
