If the application needs more code space or RAM, consider a pin-compatible upgrade within the MSP430x1xx family that offers higher Flash density and more SRAM while keeping the same 20-SOIC footprint. The integrated slope A/D converter provides a low-component-count method for reading resistive sensors (thermistors, RTDs, strain gauges) without an external ADC. The POR (power-on reset) and WDT (watchdog timer) peripherals are included on-chip, reducing external supervisor IC requirements.","metaTitle":"TI MSP430F1121AIDWR 16-bit MCU, 8MHz, 4KB Flash, 20-SOIC","metaDescription":"Texas Instruments MSP430F1121AIDWR 16-bit MCU with 8MHz core, 4KB Flash, 256B RAM, slope A/D, -40 to 85°C.
