Xintang N76E003AT20 to C51 standard DIP40 adapter board

Overview

illustrate:

1. This project is an N76E003AT20 microcontroller adapter board, which is directly compatible with the standard DIP40 packaged C51 development board. All pins have been lead out.

2. Since the N76E003 series chips do not support external crystal oscillators, pins 18 and 19 are not connected.

3. The "power indicator light" lights up to indicate that the power supply of the microcontroller is connected.

4. The "power selection switch" is used to select the development board's own power supply or the downloader power supply.

5. "Downloader voltage selection switch" is used to select the input voltage of the downloader (this switch is only effective when using a 10Pin downloader).

Revision log:

2012-02-17 Fixed a fatal error that could cause a power short circuit.

If there is any error, please contact guysxpf@163.com Thank you
