Placa Desarrollo Ch551 Microcontrolador Familia 8051 Mcs551 Itytarg

Features:

1. The CH552 chip is an enhanced E8051 core microcontroller compatible with the MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions, and the average instruction speed is 8 to 15 times faster than the standard MCS51. CH552 supports the highest system frequency of 24MHz, built-in 16K program memory ROM, 256 bytes internal iRAM and 1K bytes on-chip xRAM, xRAM supports DMA direct memory access.

2. CH552 has built-in functional modules such as ADC analog-to-digital conversion, touch key capacitance detection, 3 sets of timers and signal capture, PWM, dual asynchronous serial ports, SPI, USB device controller and full-speed transceiver.

3. CH551 is a simplified version of CH552, the program memory ROM is 10K, the on-chip xRAM is 512 bytes, the asynchronous serial port is only UART0, the package is only SOP16, the touch button is only 4 channels, and the ADC analog-to-digital conversion module and USB type are removed -C module, others are the same as CH552, you can directly refer to CH552 manual and information.

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 standard MCS51, XRAM data fast copy instruction, double DPTR pointer.
ROM: 16KB non-volatile memory ROM that can be programmed many times, can be used for program storage space; or can be divided into 14KB program storage area and 2KB boot code BootLoader/ISP program area.
DataFlash: 128-byte rewritable non-volatile data memory that supports rewriting data in units of bytes.
: 256 bytes internal iRAM, which can be used for fast data temporary storage and stack; 1KB on-chip xRAM, which can be used for large amount of data temporary storage and DMA direct memory access.

USB: Built-in USB controller and USB transceiver, supports USB-Device device mode, supports USB type-C master-slave detection, supports USB
