FRAM-based 16-bit MCU with integrated LCD drive
Its distinguishing feature is 32KB of FRAM program memory — non-volatile storage that writes at near-SRAM speeds with 10^15 cycle endurance, eliminating the erase-before-write penalty of Flash. A 2K x 8 SRAM complements the FRAM for stack and variable storage. The part integrates an LCD driver, a 12-bit ADC with 8 channels, and a full set of peripherals including DMA, PWM, brown-out reset, and watchdog timer. The supply range spans 1.8V to 3.6V, suiting both single-cell battery and regulated 3.3V rail applications.
32KB FRAM — no erase cycles, no wear-leveling needed
FRAM writes at bus speed without the sector-erase latency of Flash. For data-logging, parameter storage, or over-the-air update staging, this means the firmware can commit a byte or a word in a single cycle — no buffering to a full page, no erase-before-write. The 10^15 write-cycle endurance effectively eliminates wear-out for any realistic product lifetime, so the software stack does not need wear-leveling or a separate EEPROM emulation layer.
Package and thermal pad
The MSP430FR6970IRGCR comes in a 64-VFQFN exposed-pad package (supplier package 64-VQFN, 9x9 mm).
TI lists the MSP430FR6970IRGCR as an active product. The FRAM MSP430 family remains a current portfolio focus for TI, so this part is safe for new designs and production ramp without obsolescence risk.
