Product details

7×24-bit sigma-delta ADC array — the distinguishing feature

Its program memory is 512 KB of Flash with 16 KB of RAM. What sets this part apart is the peripheral set: seven 24-bit sigma-delta analog-to-digital converters, plus an additional 8×10-bit ADC, a segment LCD controller, and a DMA engine.

Housed in a 128-LQFP (20×14 mm body) — a standard fine-pitch QFP that routes easily on a four-layer board.

That means no last-time-buy clock is ticking; it remains a viable choice for both prototype builds and production runs.

Frequently asked questions

What is the closest pin-compatible alternative to the MSP430F67781AIPEU?

The MSP430F67781AIPEU is a specific Flash and RAM density variant within the MSP430F6xx family. Pin-compatible siblings exist across the MSP430F67xx series sharing the same 128-LQFP footprint, differing mainly in Flash (256 KB to 512 KB) and sigma-delta ADC channel count. Confirm the exact memory and peripheral complement against the target application before substituting.

How to program the MSP430F67781AIPEU?

Programming is done through the Spy-Bi-Wire (SBW) two-wire JTAG interface, supported by TI's Code Composer Studio and IAR Embedded Workbench. The bootloader is factory-loaded; no external programmer is needed beyond a standard SBW debug probe.
