EV58E84A

EV58E84A is a PIC32CXMTC-DB evaluation kit. 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 this device particularly well suited for applications such as polyphase shunt smart meters. The board includes a poly-phase (ATSENSE-301) energy metering analogue front end with three voltages 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.

• 3-phase AFE ATSENSE301 (3 voltages and 4 currents) with network divider and filters
• Measurement voltage range from 90V AC to 264V AC (Extended to 291 V AC removing power supply U1)
• Measurement current range depends on CT ratio used (default burden resistor value is 3.24ohm)
• 64Mbit 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
• Safety case to handle the board without electrical shock risk
