Its program memory is 16KB of FRAM — not Flash — which means writes are fast, nearly unlimited in endurance (10^15 cycles typical), and consume less power per byte than an EEPROM write.
Runs on 2V to 3.6V, so a single 3.3V or 3.0V lithium cell works fine. Not rated for under-hood or downhole, but fine for most commercial and industrial enclosures.
Lifecycle status is Active per TI's product bulletin. No last-time-buy notice, no end-of-life window.
The MSP430FR5739 steps up to 24KB FRAM and 2K x 8 RAM, versus 16KB FRAM and 1K x 8 RAM on the FR5729. Both share the same 38-TSSOP package, 8MHz core, and peripheral set — the extra memory headroom on the FR5739 matters if your firmware or data buffer grows beyond the FR5729's capacity.
38-TSSOP, 0.240" body width, 6.10mm wide. The 'IDAR' suffix indicates Tape & Reel or Cut Tape shipping format.
