It packs 60 KB of Flash program memory and 2 KB of RAM, plus a 12-channel 12-bit ADC and a dual 12-bit DAC on-chip — enough analog front-end for multi-sensor data acquisition or closed-loop control without external converters. The 48 general-purpose I/O lines, SPI and UART/USART connectivity, and internal oscillator keep the BOM lean for industrial or portable instruments. ## Mixed-signal integration — what the ADC and DAC mean for your design The 12-bit ADC with 12 input channels covers most analog sensor interfaces — thermocouples, strain gauges, current shunts — without an external multiplexer. The two 12-bit DAC outputs can drive analog setpoints or generate reference voltages for external circuitry. Combined with the brown-out detect and POR, the part handles power-on sequencing and brown-out recovery autonomously, which simplifies the supervisor logic on the board. This part carries an EOL lifecycle stage, meaning Texas Instruments has discontinued production. For existing BOM lines, procurement should plan for last-time-buy or transition to a pin-compatible alternative within the MSP430FG439 family.","metaTitle":"TI MSP430FG439IZCAR 16-bit MCU, 8 MHz, 60 KB Flash, 113-VFBGA","metaDescription":"Texas Instruments MSP430FG439IZCAR 16-bit MCU, 8 MHz MSP430 CPU16, 60 KB Flash, 2 KB RAM, 12-bit ADC/DAC, SPI/UART, -40°C to 85°C, 113-VFBGA.
