CH552G USB microcontroller with 16KB ROM/ 256-bytes IRAM/ 1Kbytes XRAM and DMA

Description

Description CH552G development board features the CH552 chip, which is an enhanced e8051 core single-chip microcomputer compatible with MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions, and the average instruction speed is 8-15 times faster than the standard MCS51. Ch552 supports up to 24MHz system main frequency. It has built-in 16KB program memory (ROM), 256-byte internal IRAM, and 1K bytes on-chip xram. Xram supports DMA (direct memory access). The ch552 has 4 channel capacitive touch buttons, three sets of timers and signal capture, PWM, SPI, asynchronous serial port (UART0), USB device controller, and full speed transceiver. Specifications Core: enhanced e8051 core, 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 the standard MCS51. It has a special xram data replication instruction and double dptr pointer. ROM: 16 KB capacity of multi programmable non-volatile memory ROM, can be used for all program storage space Data Flash: 128 bytes multi erasable non-volatile data memory, which supports rewriting data in bytes. RAM: 256 bytes internal RAM, which can be used for fast data storage and stack; 1K bytes on chip xram can be used for large amount of data temporary storage and DMA (direct memory access). USB: embedded USB controller and USB transceiver, supporting USB device mode, master-slave detection, supporting USB 2.0
