DESCRPIPTION AND FEATURES

51 Single-Chip Microcomputer System Board

Product Features

  1. IO ports are led out, and the 51 minimum system eliminates the trouble of welding.
  2. Integrates an ISP 10P download interface, facilitating the download for AT89S52 single-chip microcomputers.
  3. Round-hole sockets are used for welding, making it easy to replace the crystal oscillator (11.0592M is provided by default).
  4. Supported chips: STC89C52, STC12C5A60S2, STC11/10x series, AT89S52, and chips pin-compatible with the aforementioned ones.
  5. Power switch + indicator light. A power switch is convenient for experiments, and there is an indicator light.
  6. Two power input methods: DC-005 power socket (the matching socket is 5.5*2.1) and single-row pin (next to the power switch).
  7. Three external VCC and GND circuits, as shown by the pin headers in the figure.
  8. Pull-up resistors for P0 port.
  9. Reset methods: power-on reset and external key reset.
  10. Green IC lock sockets are adopted, making chip replacement easy. The movable locking sockets are convenient for frequent plugging and unplugging during experiments.
  11. Board size: 41mm*89mm

STC89C52RC

  1. SMD STC89C52RC chip

    It has 44 pins. The only difference between it and the through-hole 52 chip is that it has an additional P4 port with 4 I/O pins, which is one of its features.

  2. Supports USB power supply + download + serial communication

    Only a common USB cable is needed to program and power the chip.

  3. Supports 5V input and output, and stable 3.3V output
  4. Supports other external 5V power supplies
  5. Has unique LCD1602 and LCD12864 interfaces

  6. Has 4 more I/O pins than the through-hole STC89C52RC, namely the P4 port

    (As many friends who play with single-chip microcomputers know, although there are only 4 more I/O pins, they may play a crucial role in many competitions.)

  7. All pins of the single-chip microcomputer

    Except for the reset pin and crystal oscillator pins, all other pins are led out, and their positions are roughly the same as those of the through-hole I/O pins.

  8. The distance and size of all I/O pin holes correspond to those of the experimental board

ST-LINK V2 downloader burning and debugging

  1. Supports SWD interface debugging for the entire series of STM32. The 4-wire interface (including power supply) is simple, fast, and works stably; the interface definitions are directly marked externally! There is no need to refer to the manual!
  2. Supports SWIM download and debugging for the entire series of STM8 (supported by common development environments such as IAR, STVD, etc.); the supported software versions are as follows:

    ① ST-LINK Utility 2.0 and above

    ② STVD 4.2.1 and above

    ③ STVP 3.2.3 and above

    ④ IAR EWARM V6.20 and above

    ⑤ IAR EWSTM8 V1.30 and above

    ⑥ KEIL RVMDK V4.21 and above

  3. Supports automatic firmware upgrade to ensure subsequent support for the company’s products. The firmware is upgraded to the new V2.J17.S4 at the factory;
  4. Added 5V power output, and the output I/O ports are all protected, so there is no fear of damage caused by operational errors!
  5. The interface uses pure copper gold-plated 2.54-pitch simple 牛角座 (horn sockets), equipped with 20CM Dupont wires, which can cope with different target board wire sequences and enable flexible wiring;
  6. The motherboard is protected by an aluminum alloy U-disk shell, which is easy to carry, and is not afraid of static electricity or falling and bumping.

Eight highlights of our store's STLINK ST V2:

  1. The internal mainboard is installed using an aluminum alloy USB flash drive shell, which is convenient to carry, safe and reliable!
  2. The interface definitions are directly marked on the shell, which is clear at a glance and convenient for practical use!
  3. 5V and 3.3V are provided externally at the same time, making it convenient for you to connect 5V and 3.3V target boards.
  4. The characters on the shell are marked by laser etching, with laser engraving!
  5. The internal mainboard is equipped with a 500mA self-recovering fuse to protect your precious computer mainboard!
  6. Red and blue dual-color LED indicator lights, convenient for you to observe the working status of ST-LINK V2 at any time!
  7. 4 Dupont wires are provided, allowing you to easily deal with different target board wire sequences!
  8. The outer packaging uses an anti-static bag and is sealed by an automatic sealing machine, which is safe and reliable, not afraid of static electricity or water ingress!

Product Features

  1. Enhanced 8051 single-chip microcomputer. 6 clocks/machine cycle and 12 clocks/machine cycle can be arbitrarily selected, and the instruction code is fully compatible with the traditional 8051.
  2. Operating voltage: 5.5V – 3.3V (for 5V single-chip microcomputer) / 3.8V – 2.0V (for 3V single-chip microcomputer)
  3. Operating frequency range: 0 – 40MHz, equivalent to 0 – 80MHz of ordinary 8051, and the actual operating frequency can reach 48MHz.
  4. User application program space is 8K bytes.
  5. On-chip integrated 512-byte RAM.
  6. General-purpose I/O ports (21 in total). After reset: P1/P2/P3/P4 are quasi-bidirectional ports with weak pull-up. P0 port is open-drain output. When used for bus expansion, there is no need to add pull-up resistors; when used as an I/O port, pull-up resistors need to be added.
  7. ISP (In-System Programming) / IAP (In-Application Programming). No special programmer or emulator is required. User programs can be directly downloaded through the serial port (RxD/P3.0, TxD/P3.1), and one chip can be completed in a few seconds.
  8. With EEPROM function.
  9. With watchdog function.
  10. There are 3 16-bit timers/counters in total, namely Timer T0, T1, and T2.
  11. 4 external interrupts, with falling-edge interrupt or low-level trigger circuit. The PowerDown mode can be awakened by the external interrupt low-level trigger interrupt method.
  12. General-purpose asynchronous serial port (UART). Multiple UARTs can also be implemented with timer software.

Working Modes

  • Power – down mode: Typical power consumption < 0.1 μA. It can be awakened by an external interrupt. After the interrupt returns, the original program continues to execute.
  • Idle mode: Typical power consumption is 2 mA.
  • Normal working mode: Typical power consumption is 4 mA – 4 mA.
The power – down mode can be awakened by an external interrupt and is suitable for battery – powered systems such as water meters and gas meters, as well as portable devices.

Application

  • Education:Widely used in universities and training institutes for teaching embedded system fundamentals, as the 51 single chip microcomputer is easy to understand for beginners.
  • Home Automation:Controlling simple devices like lights, fans, and small robotic systems. For example, a 51 mcu development board with Stc89c52rc can be used to build a system that turns on lights at a specific time.
  • Industrial Control:Basic monitoring and control tasks where high – end controllers like Stm32 are not necessary, such as simple sensor data logging (temperature, humidity sensors connected via I/O ports).
  • Hobbyist Projects:Enthusiasts use 51 MCU and Stc89c52rc for building robots, remote – controlled cars, and DIY electronic gadgets.
