The Microchip PIC32CXMTSH series is a family of system-on-chip solutions for residential single- and dual-phase metering applications, offering up to class 0.2 metrology accuracy over a dynamic range of 3000:1 within the industrial temperature range and are compliant with ANSI C12.20-2002 and IEC 62053-22 standards. These metrology-enabled microcontrollers offer an unprecedented level of integration and flexibility around dual 32-bit Arm® Cortex®-M4F RISC processors to allow integration of the application layer, communications layers and metrology functions in a single device.

The PIC32CXMTSH series has been designed to meet the requirements of international Metering standards, with a distinct separation between Application/Communication and Metrology functions. Each core features an embedded Memory Protection Unit (MPU) and a high-speed bus matrix, ensuring protection of the legally relevant code from both core and peripherals access.
