71M6531 Demo Board

QUICK START GUIDE

Getting Started

The TERIDIAN Semiconductor Corporation (TSC) 71M65131 Demo Board is a demonstration board for evaluating
the 71M6531 IC for single-phase electronic energy metering applications on a two-layer PCB. It incorporates a
71M6531 integrated circuit, peripheral circuitry such as a serial EEPROM, emulator port, and on-board power supply
as well as a companion Debug Board that allows a connection to a PC through a RS232 port. The Demo Board
allows the evaluation of the 71M6531 energy meter IC for measurement accuracy and overall system use.

The Demo Board is pre-loaded with MPU Demo Code in the FLASH memory of the 71M6531 IC. This embedded
application is developed to exercise all peripherals, flash programming, and CPU management (clock, timing, power
savings, etc.), and to provide easy access to all metering information.

Downloading of any other TSC or custom application can be done through the in-circuit emulator port using the
Signum ADM51 emulator or the Flash Programmer Module (TFP-2).

Safety and ESD Notes

Connecting live voltages to the demo board system will result in potentially hazardous voltages on the demo board.

EXTREME CAUTION SHOULD BE TAKEN WHEN HANDLING THE DEMO BOARD ONCE
IT IS CONNECTED TO LIVE VOLTAGES!

THIS DEMO SYSTEM IS ESD SENSITIVE! ESD PRECAUTIONS SHOULD BE TAKEN

WHEN HANDLING THE DEMO BOARD!
