The device operates from a 1.8 V to 3.6 V supply and is rated over the industrial temperature range of -40°C to 85°C, making it suitable for factory automation, remote telemetry, and portable instrumentation where low power and mixed-signal integration are required. The MSP430F156IRTDR includes a brown-out detect and reset circuit, DMA controller, POR, PWM timer, and watchdog timer. Serial interfaces cover I²C, SPI, and UART/USART, supporting common sensor and actuator communication protocols. With 48 general-purpose I/O lines in a 64-VFQFN package (9x9 mm), the part provides sufficient pin count for mixed-signal control boards without requiring port expansion. Brown-out detection and POR ensure reliable startup and operation under brownout conditions common in battery-powered or energy-harvesting designs.","metaTitle":"TI MSP430F156IRTDR 16-bit MCU, 8MHz, 24KB Flash, 1KB RAM, -40°C to 85°C","metaDescription":"Texas Instruments MSP430F156IRTDR 16-bit MSP430 CPU16 MCU, 8MHz, 24KB Flash, 1KB RAM, 48 I/O, 8×12b ADC + 2×12b DAC, 1.8-3.6V, -40°C to 85°C, 64-VFQFN.
