Mixed-signal metrology MCU with integrated sigma-delta AFE
The Texas Instruments MSP430F67771IPZ is a 16-bit microcontroller from the MSP430F6xx family, built around the MSP430 CPUXV2 core clocked at 25MHz. It packs 256KB of Flash program memory and 32KB of RAM.

Peripherals and integration checklist
Beyond the AFE, the peripheral set includes a brown-out detect/reset, power-on reset, DMA controller, LCD driver (segment count not specified in this listing), PWM timer, and watchdog timer. The internal oscillator eliminates the need for an external crystal in many metering applications. The 62 I/O lines are enough to drive a local display, keypad, and communication module alongside the metrology front-end. The 100-LQFP footprint is a standard 14x14 mm body — no exotic pitch or hidden balls.
