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.
The 51 general-purpose I/O lines, I²C, SPI, UART, and IrDA connectivity cover most sensor and actuator interfaces.
