Description

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, the devices embed up to 2 Mbytes of embedded Flash, up to 560 Kbytes of SRAM and 16 Kb of Instruction and 8 Kb of Data Cache or Tightly Coupled Memory (TCM) on-chip.

A QSPI interface with eXecute-in-Place (XiP) coupled with on-the-fly AES128 encryption bridge futureproofs the devices and ensures platform scalability in case of memory extension needs or changing system requirements.

A Secure Boot and secure key storage coupled with advanced cryptographic/Hash hardware accelerators, such as ECC, RSA, AES128/256, and SHA256/512, support the different encryption and authentication protocols.

The series also features a segmented LCD controller, anti-tampers, Floating Point Unit (FPU), MPU, FLEXCOM peripherals supporting I²C, SPI, UART/USART interfaces, three PWMs for pulse output functions, 12-channel general-purpose 32-bit timers, 12-bit ADC, analog comparators and a battery backed-up RTC running as low as 1 μA.

PIC32CXMTC devices are available in an EP-TQFP128 pin-exposed package.
