• WCH CH552 8-Bit 8051 MCU 24MHz 16KB FLASH SOP-16

8-bit USB device microcontroller: CH552


Overview

The CH552 chip is an enhanced E8051 core microcontroller compatible with the MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions, and the average instruction speed is 8-15 times faster than the standard MCS51.

CH552 supports up to 24MHz system frequency, built-in 16K program memory ROM, 256 bytes internal iRAM and 1K bytes on-chip xRAM, xRAM supports DMA direct memory access.

CH552 has built-in functional modules such as ADC analog-to-digital conversion, touch button capacitance detection, 3 sets of timers and signal capture and PWM, dual asynchronous serial ports, SPI, USB device controller and full-speed transceiver, USB type-C.
