The 1K x 8 RAM handles stack and scratchpad. ## Serial interfaces and I/O count That's enough to hang a display, a couple of sensors, and a wireless module without an external port expander. The 14-channel 12-bit ADC (A/D 14x12b) captures analog inputs directly — no separate converter needed for thermistor or current-sense feedback. Housed in a 40-VFQFN exposed-pad package (6x6 mm body, 40-VQFN). Surface-mount only. ROHS3 compliant. The base product number is MSP430FR5957, so variants with different package or temperature grade share the same core. For a spare-parts storeroom, this part is a safe stock-keeping choice: it's current, widely available through distribution, and the FRAM technology avoids the wear-out concerns of flash-based MCUs in long-life field deployments.","metaTitle":"MSP430FR5957IRHAT 16-bit MCU, 32KB FRAM, 16 MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430FR5957IRHAT 16-bit MCU with 32KB FRAM, 16 MHz CPU, 33 I/O, I2C/SPI/UART, 1.8V-3.6V, -40°C to 85°C.

It is not a pin-compatible second source — different core architecture, supply voltage (1.14 V core), and package.
