The 25 MHz CPU speed places this part in the mid-range of the MSP430F5xx family. The 128 KB Flash and 10 KB RAM support moderate firmware footprints.
The MSP430F5329IPN carries an EOL (end-of-life) lifecycle flag, meaning Texas Instruments has issued a product discontinuation notice. Official last-time-buy windows have typically closed for this device, and new-production units are no longer being manufactured.
The supply voltage range is 1.8 V to 3.6 V (Vcc/Vdd). This covers both 3.3 V regulated rails and single-cell Li-ion battery applications down to 1.8 V.
Texas Instruments does not list a direct pin-compatible replacement within the MSP430F5xx family for this specific order code. For an active-production alternative, consider the MSP430F5438A or MSP430F533x series — these share the same CPUXV2 core and peripheral set but may differ in pinout and memory. Verify compatibility using the TI MSP430 migration guide before redesigning your board.
Submit an RFQ through this listing. We source this part through independent distribution and can confirm current pricing, available quantities, and date-code condition at quote time. No stock or price figures are published here because availability changes daily for an EOL part.
