MCU Description

MCU (Microcontroller Unit) is also called Single Chip Microcomputer. MCU is CPU with the appropriately-reduced frequency and specification, integrated with the peripheral interfaces, like memory, Timer, USB, A/D convertor, UART, PLC, and DMA, etc. Even the LCD driver circuit is integrated into single chip to realize the chip-level computer. Different combinations are carried out for different application fields.
