1/5/10pcs SMD CH551G SOP-16 10KB 8-bit enhanced USB microcontroller chip

Description

Specifications:
1 Overview
The CH52 chip is an enhanced E8051 core microcontroller compatible with the MCS51 instruction set. 79% of its instructions are single-byte single-cycle
Command, the average command speed is 8~15 times faster than standard MCS51
C552 supports up to 24MHz system frequency, built-in 16K program memory ROM and 256 bytes of internal RAM and 1K bytes of on-chip xRAM, XRAM supports DMA direct memory access.
C552 has built-in ADC analog-to-digital conversion, touch button capacitance detection, 3 sets of stabilizers and signal capture and P, dual asynchronous serial ports,
Functional modules such as SPI, USB device controller and full-speed transceiver
CH551 is a simplified version of C52, the program memory ROM is 10K, the on-chip xRM is 512 bytes, the asynchronous serial port is only UARTO and the package is only SOP16, the touch button is only 4 channels, and the ADC analog-to-digital conversion module and USB type-C module are removed. .
2. Features
core: Enhanced E8051 core, compatible with MC51 instruction set, 9% of its instructions are single-byte single-cycle instructions, average instructions
The speed is 8~15 times faster than standard MCS51, unique XRAM data fast copy instruction, double DPTR pointer
The non-volatile memory ROM with a capacity of Om16KB that can be programmed multiple times can be used for program storage space: or can be divided into 14kB program storage area and 2KB boot code Boot Loader/P program area

G10: supports up to 17 GP10 pins (including XI/X0RST and USB signal pins)
Interrupt: Supports 14 groups of interrupt signal sources, including 6 groups of interrupts (INTO, TO, INT1, T1ARTO, T2) compatible with standard MCS51, and extended 8 groups of interrupts SPI0, TKEY, UB, ADC, UArt1, GP0, G ),its
The GP10 interrupt can be selected from 7 pins
● Watch-dog: 8-bit can be preset watchdog timer, support timing interrupt.
Reset: Support 4 kinds of reset signal sources, built-in power-on reset, support software reset and watchdog overflow reset, optional pin external input reset
● Clock has a built-in 24MHz clock source, which can support external crystals by multiplexing the GP10 pin.
● Power: Built-in 5 to 3.3v low dropout voltage regulator, support 5V or 3.3V or even 2.8V power supply voltage. Support low power
Consumption sleep, support USB, UARTO, UART1, SP10 and some GP10 external wake-up
●D number built-in chip
