If you are writing a Modbus slave with a multi-page LCD menu, you will fill it fast. The 256 B of additional memory (likely info memory) can store calibration constants or serial numbers. Plan for a bootloader if field updates are needed — the Flash is reprogrammable in-system over SPI or UART. ## Lifecycle and sourcing — active, stable, no LTB watch ## Package and field replacement — 100-LQFP, no socket The 100-LQFP (14x14 mm) is a fine-pitch surface-mount package. Is it in the kit? Only if you carry a hot-air rework station and a stencil. This is not a socketed DIP you swap on site with a chip puller. If the board fails in the field, the whole PCB likely gets replaced — plan for a spare board rather than a loose IC.","metaTitle":"TI MSP430F4351IPZ 16-bit MCU, 8 MHz, 16 KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430F4351IPZ 16-bit MCU with 8 MHz core, 16 KB Flash, 512 B RAM, LCD driver, SPI/UART, -40 to 85°C.
