FRAM MCU with integrated LCD and 12-bit ADC
FRAM writes at bus speed, consumes negligible power, and retains data without a backup battery — a practical advantage over Flash for frequent-logging or field-update applications. An integrated 8-channel 12-bit ADC, LCD driver, and DMA controller let it handle mixed-signal sensing and segmented-LCD display tasks without external analog or display-interface ICs.
What the 64 KB FRAM means for your BOM
FRAM endurance is orders of magnitude higher than Flash — typically 10^15 write cycles — so the MSP430FR68721IPMR can treat its program memory as data EEPROM without wear-leveling or separate serial EEPROM. For a design that stores calibration constants, event logs, or OTA update staging, this eliminates a discrete memory component and the associated I²C/SPI bus traffic. The 64 KB capacity fits firmware images for sensor nodes, metering, and portable medical instruments where code size stays under 50 KB.
Industrial temperature and peripheral set
The 51 general-purpose I/O lines, I²C, SPI, UART, and IrDA connectivity cover most sensor and actuator interfaces. An internal oscillator keeps the BOM lean — no external crystal needed for the core clock, though the LCD frame rate may still benefit from a 32 kHz watch crystal if precise timekeeping is required.
Package and supply range
Housed in a 64-LQFP (10x10 mm) package with a 0.5 mm pitch, the device is hand-solderable and reflow-friendly.
Lifecycle and sourcing posture
Texas Instruments lists the MSP430FR68721IPMR with an active product status. The base product number MSP430FR68721 covers the full family — verify the package and temperature suffix (IPMR) matches your assembly requirements.
