Enhanced 1T 8051 single-chip microcomputer microcontroller MCU

Product introduction

              A single-chip microcomputer, also known as a single-chip microcontroller, is not a chip that performs a specific logical function. Instead, it integrates a computer system onto a single chip. It is equivalent to a miniature computer. Compared with a computer, a single-chip microcomputer only lacks I/O devices. In a nutshell: A chip becomes a computer. It is small in size, light in weight and low in price, providing convenient conditions for learning, application and development. At the same time, learning to use a single-chip microcomputer is a good choice for understanding the principles and structure of computers.

Product parameter

1. Download using PL2303-GL, and simulation is also supported

ISP download steps

1. Power off the target chip. Be sure not to power off the USB-to-serial chip (such as CH340, PL2303-GL, etc.).

2. Since the sending pin of the USB-to-serial chip is generally a strong push-pull output, a diode must be connected in series between the P3.0 port of the target chip and the sending pin of the USB-to-serial chip; otherwise, the target chip cannot be completely de-energized, and the goal of powering off the target chip cannot be achieved.

3. Click the "Download/Program" button in the STC-ISP download software.

4. Power on the target chip.

5. Start the ISP download.

2.The USB direct ISP download simulation only supports ISP download and does not support emulation

Note: When downloading via USB, P3.2 needs to be connected to Gnd for normal downloading.

ISP download steps

1.Cut off the power supply to the target chip.

2. Connect P3.0/P3.1 to the USB port in the way shown in the figure.

3. Short-circuit P3.2 to GND.

4. Power on the target chip and wait for "STC USB Writer (USB1)" to be automatically recognized in the STC-ISP download software.

5. Click the "Download/Program" button in the download software (Note: The operation sequence is different from that of serial port download).

6. Start the ISP download.
