The Microchip PIC32CXMTC series is a family of system-on-chip solutions built around dual 32-bit Arm® Cortex®-M4F RISC processors. The series features an optimized two-wire interface for reducing the isolated interconnect with Microchip's Analog Front End (AFE), making these devices particularly well suited for applications such as polyphase shunt smart meters.

With the Application core running at a maximum speed of 200 MHz, and up to 240 MHz for the Metrology core, PIC32CX5112MTC128 includes 512 kBytes of embedded Flash, 176 kBytes of SRAM and 16 kB of Instruction and 8 kB of Data Cache/Tightly Coupled Memory (TCM) on-chip. PIC32CX5112MTC128 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.
