For a design that polls a 12-bit ADC, runs a PID loop, and refreshes a segment LCD, 8 MHz is adequate. ## 60 KB Flash and 2K RAM — firmware budget and data buffer 60 KB of Flash (organized as 60K x 8 plus 256 bytes) holds moderate firmware — enough for a communication stack (SPI, UART), LCD driver routines, and calibration tables. The 2K x 8 RAM is tight; expect to use the Flash for lookup tables and rely on the DMA for ADC buffering rather than large software FIFOs. Designs that need more RAM should look at the MSP430x4xx parts with 4K or 8K options, but those typically drop the LCD or DAC integration. Brown-out detection and POR are built in, so external reset supervision is optional.","metaTitle":"TI MSP430FG439IZCAT 16-bit MCU, 8 MHz, 60 KB Flash, 113-BGA","metaDescription":"MSP430FG439IZCAT from TI: 16-bit MCU, 8 MHz, 60 KB Flash, 2K RAM, 12-bit ADC/DAC, LCD driver, -40 to 85°C, 113-NFBGA.

TI no longer manufactures it in the 113-NFBGA package. For a pin-compatible alternative, the MSP430FG439IPN in LQFP-80 uses the same core and peripherals but requires a different PCB footprint."},{"question":"What is the operating voltage and temperature range of MSP430FG439IZCAT?","answer":"Supply voltage is 1.8 V to 3.6 V. Operating temperature range is -40°C to 85°C (industrial grade)."},{"question":"Is MSP430FG439IZCAT equivalent to MSP430F449?","answer":"No. The MSP430F449 is a different variant with 60 KB Flash and an LCD driver but no on-chip DAC and fewer ADC channels (8 vs 12). The FG439 adds a 12-bit DAC and a 12-channel ADC. Pinout and package also differ — the FG439IZCAT is BGA-only, while the F449 is available in LQFP. They are not drop-in replacements."},{"question":"Where can I buy MSP430FG439IZCAT available via RFQ confirmation?","answer":"We source MSP430FG439IZCAT through independent distribution. Submit an RFQ for current availability and pricing — stock levels and lead times are confirmed at quote time. Given the EOL status, prompt ordering is advised."},{"question":"What is MSP430FG439IZCAT's listed speed?","answer":"The core runs at 8 MHz. That is the maximum clock frequency for this MSP430 CPU16 device."},{"question":"What is the closest pin-compatible alternative to MSP430FG439IZCAT?","answer":"Within the same BGA footprint, there is no direct pin-compatible alternative — TI did not release a second BGA variant with the same ball-out. The MSP430FG439IPN (LQFP-80) uses the same die but a different package. For a BGA-to-BGA swap, you would need a PCB redesign."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FG439IZCAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FG439IZCAT when reusing this data.
