Frequently asked questions
What is the closest pin-compatible alternative to MSP430F2491TPM in this component family?
Within the MSP430F2xx series, the MSP430F2491TPM is a specific Flash and RAM density variant. Pin-compatible siblings exist across the F2xx lineup with different memory sizes — for example, the MSP430F2481 offers 48 KB Flash with the same pinout and peripheral set. Check the TI device comparison table for exact memory and feature deltas.
What programmer is compatible with MSP430F2491TPM?
The MSP430F2491TPM uses the standard Spy-Bi-Wire (SBW) or JTAG debug interface common to all MSP430F2xx devices. TI's MSP-FET programmer, the eZ-FET on LaunchPad boards, and third-party tools like the Segger J-Link (with MSP430 support) all work. The SBW two-wire interface requires only SBWTCK and SBWTDIO connections.
