CH554G - E8051 Core MCU - USB Host/Device - SOP-16
NEW
The CH554 chip is an enhanced E8051 core microcontroller compatible with the MCS51 instruction set. Its 79% instruction is a single-byte single-cycle instruction, and the average instruction speed is 8 to 15 times faster than the standard MCS51. The CH552 supports up to 24MHz system frequency, built-in 16K program memory ROM and 256 bytes of internal iRAM and 1K bytes of on-chip xRAM. xRAM supports DMA direct memory access. CH554 has built-in ADC analog-to-digital conversion, touch button capacitance detection, 3 groups of timers and signal capture and PWM, dual asynchronous serial port, SPI, USB device controller and full-speed transceiver, USB type-C and
other functional modules.
