That means you can treat it as a single memory pool for firmware and persistent data, which simplifies the BOM by eliminating a separate serial EEPROM for calibration constants or configuration parameters. The 24 MHz clock is enough for sensor polling, communication protocol handling, and control loops, but this isn't a part for heavy DSP or video processing — it's a low-power, mixed-signal MCU for applications where the FRAM write endurance and speed matter more than raw MIPS. ## Supply and temperature — where this part lives on the board The MSP430FR5738IRGER runs from a 2V to 3.6V supply, which covers two alkaline cells in series or a regulated 3.3V rail. The wide range means you can skip a boost converter in battery-powered designs and still have headroom for the internal LDO. ## Peripherals and I/O — what's on the pins That covers the common serial buses for sensor interfaces, display modules, and industrial fieldbuses. The internal oscillator means you don't need an external crystal for the core clock, though the accuracy is good enough for UART at typical baud rates — if you need a precise timebase for CAN or high-speed SPI, you'll still want an external resonator. The 8-channel 10-bit ADC is there for analog sensor inputs, and the built-in brown-out reset and POR handle power-up sequencing without an external supervisor. ## Lifecycle and sourcing — no LTB pressure here TI lists this part as Active in production, so there's no last-time-buy clock ticking.","metaTitle":"MSP430FR5738IRGER Texas Instruments 16-bit MCU, 24MHz","metaDescription":"TI MSP430FR5738IRGER 16-bit MCU with 24MHz CPU, 16KB FRAM, 1K x 8 RAM, 17 I/O, I²C/SPI/UART, -40°C to 85°C, 24-VQFN.
