CH551G 8Bit ADC - 8051 Core MCU - 24MHz - 10KB Flash - USB Microcontroller IC - SOP16
CH551 is an enhanced E8051 core MCU, compatible with MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions. The average instruction speed is 8~15 times faster than that of standard MCS51. CH551 supports up to 24MHz system clock frequency. CH551 has built-in capacitive touch-key detection, 3 timers and 2-channel signal capture and PWM, UART, SPI, USB device controller and full-speed transceiver and other functional modules. CH551 is a simplified MCU of CH552, with 10K program memory ROM and 512-byte internal xRAM. CH551 only has UART0. The package of CH551 is SOP16 only. CH551 does not provide ADC module or USB type-C module. Others of CH551 are the same as that of CH552, please refer to CH552 datasheet and technical resources directly.
