FRAM at 3.75 KB — no more sector-erase planning
The MSP430FR2311IPW16 is a 16-bit microcontroller from TI's MSP430 FRAM family, built around the MSP430 CPU16 core running at 16 MHz. Its program memory is 3.75 KB of FRAM — ferroelectric RAM that writes at bus speed with effectively unlimited endurance, unlike Flash or EEPROM. That means you treat it like RAM for data logging and configuration storage, without managing sector-erase cycles or wear-leveling. The 1 K x 8 SRAM handles stack and scratchpad. On-chip peripherals include a 10-bit ADC with 8 channels, I²C, SPI, UART, PWM, and a brown-out reset.
At 16 MHz the single-cycle multiply and 16-bit RISC pipeline give deterministic throughput for sensor read-and-react loops. For a 10-bit ADC conversion triggered by a timer, the CPU can process the result and update a PWM duty cycle within a few microseconds — no cache misses, no branch prediction stalls.
Active, ROHS3, and in a 16-TSSOP
It ships in a 16-TSSOP package (4.40 mm width, 0.65 mm pitch), surface-mount only.
Supply range and I/O — sizing the BOM
With 11 GPIOs available in the 16-TSSOP package, the pin count is tight. If your design needs more than 11 I/O or a larger code space, the MSP430FR2x family offers higher-density FRAM options in larger packages.
