Overview
The PIC32CXMTC-DB lets designers quickly evaluate and develop code for smart energy applications built around two high performance 32-bit Arm® Cortex® -M4F processors. PIC32CMXTC dual Arm Cortex-M4F architecture allows the integration of the application layer, communications layers and metrology functions in a single device. PIC32CMXTC 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. The board includes a Poly-phase (ATSENSE-301) Energy Metering Analog Front End with three voltage and four current sense channels. Current channels are designed to interface with current transformers, Rogowski coils and shunt current sensors. It can also interface with communications devices such as PLC and/or RF modules.
- Dual Arm Cortex-M4F core (application and metrology)
- 3-Phase AFE ATSENSE301 (3 voltages and 4 currents) with network divider and filters
- Measurement voltage range is from 90 Vac to 264 Vac. It can be extended to 291 Vac removing the power supply (U1)
- Measurement current range depends on the CT ratio used (default burden resistor value is 3.24Ω). Compliant with CT, Shunt or Rogowski Coil sensors
- 64 Mbit Quad IO SPI Flash memory for meter data storage and firmware update
- User Interfaces:
- Isolated UART interface by USB bridge
- Opto-Port interface compliant with ANSI C12.20 protocol for AMR
- Isolated access to metering pulses (Wh, VARh, VAh) by an Opto-Port and/or an isolated interface
- Extension connector for External AFE connection such as MCP3910
- Custom Liquid Crystal Display dedicated for Microchip metering platform
- Interface for Xplained PRO boards (such as ATREB215-XPRO and PL460-EK) with XPRO Power Header and mikroBUS™ standard add-on boards
- Safety case to handle the board without electrical shock risk
