FRAM-based 16-bit MCU for low-power sensing and display applications
Its 64 KB of FRAM program memory combines the non-volatility of Flash with faster write speeds and essentially unlimited endurance — a practical advantage for data-logging, over-the-air firmware updates, and frequent parameter storage. The device integrates 2K x 8 SRAM, 51 general-purpose I/O lines, an internal oscillator, and a rich set of peripherals including a 12-bit ADC (8 channels), LCD driver, DMA, and PWM.
Connectivity and interface options
The 51 I/O lines in a 64-LQFP package leave room for a segmented LCD panel and a keypad matrix alongside the serial buses.
Supply voltage and power management
The base product number is MSP430FR6872, so pin-compatible siblings with different memory or peripheral mixes share the same 64-LQFP footprint for a board-spin upgrade path.
