Description
Introduction: 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 8-15 times faster than the standard MCS51. CH552 supports up to 24MHz system main frequency, built-in 16K program memory ROM, 256-byte internal iRAM and 1K byte on-chip xRAM, and xRAM supports DMA direct memory access. 2.CH552 has built-in ADC analog-to-digital conversion, touch key capacitance detection, three sets of timers and signal capture and PWM, dual asynchronous serial port, SPI, USB device controller and full-speed transceiver and other functional modules. 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 packaging form is only SOP16, the touch button is only 4 channels, and the ADC analog-digital conversion module and USB type-C module are removed. Other modules are the same as CH552. You can directly refer to the CH552 manual and data. Core: The enhanced E8051 core is compatible with the MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions. The average instruction speed is 8 to 15 times faster than the standard MCS51. It has a unique XRAM data fast copy instruction and dual DPTR pointers. ROM: 16KB capacity programmable non-volatile memory ROM, which can be used for program storage space; Or it can be divided into 14KB program storage area and 2KB boot code BootLoader/ISP program area. DataFlash: 128 bytes of non-volatile data storage that can be rewritten multiple times. It supports rewriting data in bytes. RAM: 256 bytes of internal iRAM, which can be used for fast data temporary storage and stack; 1KB on-chip xRAM can be used for a large amount of data temporary storage and DMA direct memory access. USB: embedded USB controller and USB transceiver, supporting USB-Device device mode, USB type-C master-slave detection, and USB 2.0 full-speed 12Mbps or low-speed 1.5Mbps. It supports up to 64 bytes of data packets, built-in FIFO, and DMA. Timer: 3 sets of timers. TO/T1/T2 is the standard MCS51 timer. Capture: Timer T2 is expanded to support 2-way signal capture. PWM: 2 sets of PWM outputs, PWM1/PWM2 is 2-way 8-bit PWM output. UART: 2 sets of asynchronous serial ports, all of which support higher communication baud rate. UARTO is a standard MCS51 serial port. SPI: The SPI controller has a built-in FIFO, and the clock frequency can reach half of the main frequency of the system Fsys. It supports serial data input/output simplex multiplexing, and master/slave mode. ADC: 4-channel 8-bit A/D analog-to-digital converter, supporting voltage comparison. Touch-Key: 6-channel capacitance detection, support up to 15 touch keys, and support independent timing interrupt. Serial GPIO: supports up to 17 GPIO pins (including XI/XO, RST and USB signal pins). Lnterrupt: supports 14 groups of interrupt signal sources, including 6 groups of interrupts (INTO, TO, INT1, T1, UARTO, T2) compatible with standard MCS51, and 8 groups of extended interrupts (SPIO, TKEY, USB, ADC, UART1, PWMX, GPIO, WDOG), where GPIO interrupts can be selected from 7 pins. Watch-Dog: 8-bit watchdog timer WDOG can be preset, and timing interrupt is supported. Reset: supports 4 reset signal sources, built-in power-on reset, software reset and watchdog overflow reset, and optional pin external input reset. Clock: Built-in 24MHz clock source can support external crystal by multiplexing GPIO pin. Power: Built-in 5V to 3.3V low-voltage differential voltage regulator, supporting 5V or 3.3V or even 2.8V power supply voltage. Support low-power sleep, USB, UARTO, UART1, SPIO and some GPIO external wake-up The chip has a built-in uniqueID number. Parameters: Power supply voltage: 5V or 3.3V or even 2.8V Support USB-Device device mode Support USB-Device device mode Support USB type-C master-slave detection Board size: 49mm * 19.5mm Take CH552 as an example to download USB: 1.
