Peripherals and connectivity for a metering SoC
On the digital side you get I²C, SPI, and UART serial interfaces, plus IrDA for optical communication — common in meter reading. The LCD driver on the peripheral list can drive a segment display directly, saving an external driver IC. Brown-out detect and POR are built in, along with a DMA controller for moving samples without CPU intervention. The internal oscillator keeps the BOM simple for non-critical timing; an external crystal can be added for the sigma-delta clock if accuracy demands it.
Lifecycle and sourcing reality
The lifecycle stage for this part is recorded as eol_hot, which indicates end-of-life planning is active. The official product status is marked Active, so production has not ceased, but procurement should treat this as a part with a finite window. We source and quote the MSP430F67621IPNR to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. For dual-sourcing or a drop-in replacement, the MSP430F67621 family shares the same pinout across density options — verify the specific Flash/RAM and ADC count against your firmware image.
