Product information:
STC15F2K60S2 series single-chip microcomputer is a single clock/machine cycle (1T) single-chip machine produced by Hongjing Technology. It is a new generation 8051 single-chip machine with high-speed/low power/super resistance.Times.Internal integrated MAX810 special reset circuit, PWM, 8 high -speed 10 -bit A/D conversion (250K/s), for motor control, strong interference occasions
STC15F2K60S2 is the 8051 series single -chip microcomputer. Compared with the ordinary 51 single -chip microcomputer, the following characteristics are:
RAM data memory in the large capacity 2048 byte sheet
High -speed: 1 clock/machine cycle, enhanced 8051 kernel (STC Y5), speed is 7-12 times faster than traditional 8051
The speed is also 20% faster than the STC's early 1T series microcontroller (such as the STC12/11/10 series)
Width voltage: 5.5 ～ 3.8V, 2.4 ～ 3.6V (STC15L2K60S2 series)
Low -power design: low -speed mode, free mode, power loss mode (can be wake up from external interruption or inside, inside, wake up)
Internal high-precision R/C clock, ± 1% warm fluttering (-40 ℃ ~+85 ℃), warm fluttering at room temperature 5 ‰, can completely save the external expensive crystal clock, the internal clock is available from 5MHz ~ 35MHz to choose from
The internal high and reliable reset, the voltage of the 8 -level reset threshold for ISP programming is available, completely saving the external reset circuit
The resources that support the removal of electricity wake-up are: int0/int1 (can be interrupted by up/down/down along the rising edge/-InT3/-INT4 (decrease edge interruption); CCP0/CCP1/CCP2/RXD2/T0/T1/T2 tube feet; inside power drop to wake up for special timers
Working frequency: 5-35MHz, equivalent to ordinary 8051: 60 ～ 420MHz
8/16/24/32/40/48/56/60/61k intellarly FLASH program memory, the number of rubbings of more than 100,000 times
EEPROM (Flash) function in a large capacity film, more than 100,000 times in writing
ISP/IAP (in system programming/in application programming), no programmer/simulator requires
High -speed ADC, 10 bits of 8 channels, a speed of 300,000 times/second.3 Road PWM can also be used as 3 D/A
3 Channel capture/comparison unit (CCP/PCA/PWM) ----- can also be used to realize 3 road D/A 3 timers or 3 external interruptions
6 timers, 2 16 -bit heavy -duty timer T0 and T1 are compatible with ordinary 8051 timers, add a 16 -bit timer T2, and can achieve clock output. 3 CCP/PCA can be achieved againTimer
The programmable clock output function (the clock input of the internal system clock or the outer pipe foot is input for clock frequency output):
① T0 output clock in P3.5;
② T1 output clock in P3.4;
③ T2 output clock at the P3.0, the output clocks of the above 3 timers/counter can be output frequency output;
④ The internal main clock outputs the clock in P5.4/MCLKO (the main clock of the STC15 series 8-PIN single-chip microcomputer is out of P3.4/mcLko output clock)
Hardware Watch Dog (WDT)
SPI high -speed synchronous serial communication interface
Double serial port/UART, two completely independent high -speed asynchronous serial communication ports, timely switching can be used as 5 groups of serial ports
Advanced instruction set structure, compatible with ordinary 8051 instruction set, hardware multiplication/method of removal instruction
Universal I/O port (42/38/30/26), after reset: quasi -two -way port/weakly pull (8051 traditional I/O port)
There are four modes of setting: quasi -two -way port/weak pull, strong push -pull/strong pull, only input/high resistance and leakage
Each I/O port driving capacity can reach 20mA, but the maximum of the entire chip should not exceed 120mA
If the I/O port is not enough, you can use 3 ordinary I/O ports to connect 74HC595 (￥ 0.21 yuan) to expand the I/O port.D as a button scan to save I/O ports
The characteristics of this core board are as follows:
1. Use STC15F2K60S2-28i industrial-grade chip;
2. One power indicator LED light;
3. One reset button;
4. Elective 3.3V regulatory chip;
5. Reserved external crystal in the form of sockets: can easily replace the crystal;
6. Reserve RXD, TXD, GND, 5V pins (can be power supply, download program, etc.);
7. Use the power switch to facilitate the power -off operation of the core board;
8. Reserve 4 fixed installation holes to facilitate the fixed line board!
9. Reserve 5V, 3.3V needle input/output interface
Two double-row 2.54mm row stitches will lead the P0-P4 interface all out
Core board size: 45.6*45.7mm
In order to improve the efficiency, the core board does not weld the pins and needs to be welded by the customer. Please pay attention to this detail before taking
Therefore, low -cost sales of core boards do not provide technical support!

Serial port test program description:
Serial port 1 full duplex interrupt mode receiving and receiving communication program.This routine uses the internal crystal 22.1184MHz clock, and the serial port is set to: 115200,8, n, 1. 1. Send data to the MCU via PC. After receiving the MCU, the original data received by the serial port returns the original data.
This product cannot be called a learning board, it can be called a development board or a core board, and it is only for developers to improve development speed.
Our shop is profitable and sells. Before the post is issued, only the appearance detection, the writing test, and the simulation connection detection.Please test it in time after the goods are requested.Test and then welded pins!Those who have problems after welding do not support return!
