Product details

MSP430F67641IPZR — 16-bit metering MCU with integrated sigma-delta

The Texas Instruments MSP430F67641IPZR is a 16-bit microcontroller built around the MSP430 CPUXV2 core, running at 25 MHz. It packs 128 KB of Flash program memory and 8 KB of RAM, with a peripheral set tailored for precision measurement and mixed-signal control: three 24-bit sigma-delta ADCs for direct sensor interface, plus an 8-channel 10-bit auxiliary ADC. Connectivity includes I²C, SPI, UART, and IrDA, and the device drives up to 72 general-purpose I/O lines. It operates from 1.8 V to 3.6 V over the industrial temperature range of -40°C to 85°C, housed in a 100-pin LQFP (14×14 mm) package. Typical applications include polyphase energy metering, power-quality monitoring, and industrial sensor hubs where the on-chip sigma-delta converters eliminate external analog front-end components.

25 MHz core — what it buys the metering loop

The 25 MHz CPUXV2 core services three simultaneous 24-bit sigma-delta conversions and handles communication stacks.

Lifecycle and sourcing reality

Frequently asked questions

What is the operating voltage range of MSP430F67641IPZR?

The supply voltage range is 1.8 V to 3.6 V (Vcc/Vdd). All I/O pins are 5 V tolerant on most ports, but the core and analog blocks must stay within the rated supply.

What are the alternatives or replacement for MSP430F67641IPZR?

Within the MSP430F6xx family, pin-compatible alternatives include the MSP430F677x series with larger RAM (16 KB) and additional sigma-delta channels. No direct second-source from another manufacturer is listed; verify pin compatibility against the specific package variant before substituting.
