IAP12C5A60S2-LQFP-44

Overview

IAP12C5A60S2-LQFP-44 core board, this chip does not have an emulation function! This time, an offline download button has been added again, for when someone breaks the board and uses it as a download board. I have made several such boards just to reduce the time required. The trouble of pressing the switch.

The principle of the online download circuit will not be introduced anymore. You can see this link:

The picture below shows the core board. It is led out with 2.54 pin headers. It can also be replaced with female headers. The circuit is very simple. , a switch that allows updating the program, and a 12.00MHZ 3225 passive chip crystal oscillator.
