Product details

24-bit ADC — the part's reason for being

Memory and I/O — right-sized for a single-function sensor node

16 KB Flash and 512 B RAM are tight — enough for a dedicated metrology firmware image, but not for a multitasking RTOS or large data buffers. The 11 general-purpose I/O pins handle local control (relay drive, LED indication) and interface to a host via SPI or UART. Brown-out detection and a watchdog timer are built in, so an external supervisor IC is unnecessary. The 24-TSSOP package (4.4 mm wide) fits on compact two-layer boards common in smart-plug and power-monitor designs.

Frequently asked questions

What is the datasheet for msp430afe251ipwr?

The full datasheet for the MSP430AFE251IPWR is available from Texas Instruments under the base product number MSP430AFE251. It covers the 24-bit ADC timing, Flash endurance, and power consumption curves.

What is the closest pin-compatible alternative to MSP430AFE251IPWR?

Within the same MSP430AFE2xx family, the MSP430AFE253IPWR is a pin-compatible variant with two 24-bit ADC channels instead of one, sharing the same 24-TSSOP footprint and supply range.

Is MSP430AFE251IPWR compatible with 3.3 V logic?

Yes, the device operates from 1.8 V to 3.6 V, so it is fully compatible with 3.3 V logic levels without level shifters.
