Product details

Polyphase energy metering MCU with integrated sigma-delta ADCs

The Texas Instruments MSP430F67641AIPZR is a 16-bit MSP430 CPUXV2 microcontroller clocked at 25 MHz, with 128 KB of Flash program memory and 8 KB of RAM. Its distinguishing feature is the set of three 24-bit sigma-delta analog-to-digital converters integrated on-chip, purpose-built for direct current and voltage sensing in polyphase energy metering. The MCU also includes an 8-channel 10-bit SAR ADC, 72 general-purpose I/O lines, and connectivity peripherals covering I²C, SPI, and UART/USART with IrDA support. Operating from 1.8 V to 3.6 V and rated over -40°C to 85°C, it is housed in a 100-pin LQFP (14x14 mm) package.

Three 24-bit sigma-delta converters — no external AFE needed

Package and memory fit for a BOM line

The 100-LQFP (14x14 mm) footprint is a common MCU package that routes easily on a two-layer PCB. The 128 KB Flash and 8 KB RAM are sized for a metrology application with a communication stack (e.g., Modbus RTU over UART) and a small LCD driver — the MCU includes an LCD controller as a peripheral. The 72 I/O provide ample room for tamper detection, relay drivers, and status LEDs without an external GPIO expander.

Frequently asked questions

Can MSP430F67641AIPZR be used for three-phase energy metering?

Yes, the three integrated 24-bit sigma-delta converters are designed for direct sampling of voltage and current from three phases. The 25 MHz CPUXV2 core has sufficient throughput to run a metrology algorithm and communication stack on a single chip.

What is the speed of MSP430F67641AIPZR?

The MSP430 CPUXV2 core runs at 25 MHz.
