1. INTRODUCTION
This document describes EMDB6812 Demoboard for EM6812 microcontroller.
This board contains a Flash EM6812 microcontroller and additional parts to evaluate EM6812 product and
test your application.
You will be able to :
-
Program with external programmer the Flash EM6812 through the dedicated In-System-Programming
connector or by On-Socket insertion mode
- Evaluate or run your application with the help of the existing components assembled on the board
(push-button, leds, buzzer, RS232 interface, switches) and open extensions (connectors, user area).
