... TERIDIAN Semiconductor Corporation’s (TSC) 71M652X single chip Energy Meter Controllers are a family of Systems- on-Chip that supports all functionalities required to build a low-cost power meter. Demo Boards are available for each chip (71M6521DE/FE, 71M6521BE) to allow development of embedded application, in conjunction with an In-Circuit Emulator. Development of a 71M652X application can be started in either 80515 assembly language, or more favorably in C using the Demo Boards. TSC provides, along with the 71M652X Demo Boards, a development toolkit that includes a demonstration program (“ ...
