Overview
CH549 is an enhanced E8051 core MCU, compatible with MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions. CH549 features high run speed. CH549 has built-in 60KB Flash-ROM and 2K+256B RAM. CH549 has built-in USB controller and USB transceiver. CH549 supports USB Host mode and USB Device mode, supports USB2.0 full-speed (12Mbps) and low-speed (1.5Mbps) transfer, and supports USB PD and Type-C. CH549 supports up to 64 bytes of data packet, with built-in FIFO, and supports DMA. CH549 provides abundant interface sources, including 4 UARTs and 8-channel PWM. CH549 also has 1-channel master/slave SPI, 16-channel 12-bit ADC, and supports voltage comparator. CH549 has 3 built-in timers and 3-channel signal capture. CH549 supports up to 44 GPIOs.
