The MSP430F67651IPEU: Six independent 24-bit sigma-delta ADCs on-chip. 90 I/O lines, LCD driver, PWM, and watchdog timer.
The 128-LQFP package with a 20x14 mm body is a common footprint for metrology MCUs. The 0.5 mm pitch requires careful routing on the analog front-end traces to the ΣΔ inputs.
There is no announced PCN or EOL for this base product number.
The CPU core runs at 25 MHz. This sets the timing budget for the metrology loop and real-time peripheral updates.
No direct replacement is necessary — the part is active and in production. If a second source is needed, the MSP430F67651IPNR is the same die in a different reel quantity.
