CH549G USB microcontroller with 60KB ROM/ 256B IRAM/ 2Kbytes XRAM and DMA

Description

Overview CH549 is an enhanced E8051 MCU compatible with MCS51 instruction set, 79% of which are single-byte single-cycle instructions, and the average instruction speed is 8 to 15 times faster than that of the standard MCS51. CH549 supports up to 48MHz system clock frequency, ans has built-in 64K program memory Flash-ROM and 256-byte internal iRAM and 2 Kbytes of internal xRAM. And xRAM supports direct memory access (DMA). CH549 has a built-in 12-bit ADC, capacitive touch key detection module, temperature sensor (TS), built-in clock, 3 timers and 3 channels of signal capture, 8 channels of PWM, 4 UARTs, SPI and other functional modules. It supports full-speed and low-speed USB-Host mode and USB-Device mode as well as USB type-C. CH543 is recommended when complete PD function is required. Features Core: Enhanced E8051 core compatible with MCS51 command set, 79% of which are single-byte single-cycle commands, and the average command speed is 8 ~ 15 times faster than that of the standard MCS51, with special XRAM data fast copy command, and double DPTR pointers. ROM: 64KB nonvolatile memory Flash-ROM, supoorts 10K times of erase and program, and can all be used for the program storage space; or it can be divided into a 60KB program storage area, a 1KB data storage area EEPROM and a 3KB BootLoader/ISP program area. EEPROM: 1KB EEPROM, which is divided into 16 independent blocks, supports single-byte read, single-byte write, block write (1 ~ 64 bytes), block erase (64 bytes) operat
