The 1K x 8 SRAM handles stack and scratchpad, while the integrated 8-channel 10-bit ADC and serial interfaces (I²C, IrDA, SCI, SPI, UART/USART) reduce external glue logic for sensor-node and control-loop designs. ## FRAM vs Flash — the real difference in a production build The 3.75 KB FRAM is the part's defining differentiator against Flash-based MCUs. FRAM writes at bus speed without a page-erase cycle, so a firmware parameter update that takes 5 ms on a typical Flash part happens in microseconds here. Endurance is effectively unlimited — rated for 10^15 write cycles versus Flash's 10^4–10^5. For a design that logs sensor readings every second over a ten-year service life, that eliminates wear-leveling logic and the risk of silent data loss. The trade-off: FRAM density is lower than Flash at the same price point, so code size needs to fit within 3.75 KB. This part targets code-constrained, write-heavy applications — not a general-purpose replacement for a 64 KB Flash MCU. ## Peripheral set — what hooks up without extra chips The 8-channel 10-bit ADC samples at rates adequate for slow sensor readouts — think thermistor, photodiode, or strain-gauge bridges. The internal oscillator runs at 16 MHz, saving a crystal for non-critical timing; for precision clocking, an external crystal connects to the LFXT pins. Watch the 4.40 mm-wide 16-TSSOP footprint — it is the same 4.4 mm body as a standard SOIC-16, so layout reuse is straightforward.","metaTitle":"TI MSP430FR2311IPW16R 16-bit MCU, 3.75KB FRAM, 16MHz","metaDescription":"Texas Instruments MSP430FR2311IPW16R 16-bit MCU with 3.75KB FRAM, 1KB SRAM, 8ch 10-bit ADC, I2C/SPI/UART.
