Vi điều khiển CH547G 8-bit Enhanced USB MCU

CH547 is an enhanced E8051 core MCU, compatible with MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions. CH547 features high run speed. CH547 has built-in 60KB Flash-ROM and 1K+256B RAM. CH547 has built-in USB controller and USB transceiver, supports USB Device mode, and supports USB2.0 full-speed (12Mbps) and low-speed (1.5Mbps) transfer. CH547 supports up to 64 bytes of data packet, with built-in FIFO, and supports DMA. CH547 provides abundant interface sources, including 4 UARTs and 4-channel PWM. CH547 also has 1-channel master/slave SPI, 12-channel 12-bit ADC, and supports voltage comparator. CH547 has 3 built-in timers and 1-channel signal capture. CH547 supports up to 44 GPIOs.
