At 16MHz the core can poll a sensor, update a segment LCD, and log data to FRAM in a single active burst before dropping back to sleep. The internal oscillator means no external crystal is needed for many applications, though the peripheral clock tree can still run a real-time counter from a 32 kHz watch crystal if the application demands it. For designs that need deterministic interrupt response, the 16-bit RISC pipeline delivers single-cycle multiply and hardware multiplier support without wait states from FRAM at this speed. ## 64KB FRAM — no wear-leveling, no erase cycles, no separate EEPROM FRAM writes at bus speed and consumes roughly 250x less energy per byte than Flash. For a metering application that logs consumption data every second over a ten-year product life, FRAM handles over 10^15 write cycles — effectively unlimited. The 64KB space is unified: code and data share the same memory map, so calibration constants, configuration tables, and firmware patches all live in the same FRAM array without sector-erase overhead. The 2K x 8 RAM handles stack and scratchpad; FRAM handles the rest. This architecture simplifies the firmware engineer's job and reduces BOM cost by removing the external serial EEPROM that a Flash-only MCU would need for non-volatile data storage. ## Supply range and temperature — industrial-grade operation Brown-out detect and POR are integrated, so the reset circuit is internal — no external supervisor IC needed. The 56-TSSOP package with 0.65mm pitch is a standard footprint for hand-assembly or reflow, and the exposed pad (if present on this variant) should be stitched to ground with thermal vias if the application draws sustained current above a few mA. Texas Instruments continues to manufacture this part, and no last-time-buy or end-of-life notification has been issued. The base product number MSP430FR6922 covers multiple package and temperature variants, so a PCN affecting one package option would not necessarily impact the 56-TSSOP version. ## Sourcing this part for your BOM For a production BOM line, the 56-TSSOP package and active lifecycle mean the part can be dual-sourced across multiple TI-authorized channels without qualification risk. If your design requires the same FRAM and LCD feature set in a smaller footprint, the MSP430FR6922 family includes a 48-pin QFP variant; pin compatibility should be verified against the specific package drawing before swapping.","metaTitle":"MSP430FR6922IG56R 16-bit MCU, 16MHz, 64KB FRAM, 56-TSSOP","metaDescription":"Texas Instruments MSP430FR6922IG56R 16-bit MCU with 16MHz CPU, 64KB FRAM, 2KB RAM, 8x12-bit ADC, LCD driver, 46 I/O, -40°C to 85°C.
