Overview
CH554 is an enhanced E8051 core MCU, compatible with MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions. CH554 has a built-in 24MHz clock source, built-in 1K+256B RAM and 16KB iFlash-ROM. CH554 provides abundant interface sources, including ADC, 3 timers and signal capture and PWM, 2 UARTs, SPI, etc. CH554 provides 6-channel capacitive detection module, and it supports up to 15 touch-keys in mutual capacitance mode. CH554 has built-in full-speed USB controller, and supports USB Host mode and USB Device mode.
