The standout feature here is the integrated analog: five 16-bit ADC channels and one 12-bit DAC, which saves board space and BOM cost in designs that need precision measurement and a clean analog output. The 113-VFBGA Microstar Junior package (7x7 mm) keeps the footprint small, but that BGA means rework is a hot-air station job — not a field-swap part. If you have this on a legacy BOM, you are looking at the independent surplus and broker channel for supply. No direct factory orders; no lead-time promise from TI. Plan for a qualification effort if you need to move to a current-production alternate. ## 8 MHz core and the analog payload At 8 MHz the CPU16 core is not a speed demon — this is a power-conscious part, not a number cruncher. The real value is the 16-bit ADC resolution: five channels give you simultaneous or multiplexed readings for multi-sensor inputs (pressure, temperature, flow) without an external ADC. The single 12-bit DAC handles one analog output, say a setpoint or a waveform. The 48 I/O lines, with the LCD driver and PWM peripheral, make it a fit for instrument panels or motor-control interfaces that need local display drive. The 113-ball VFBGA (7x7 mm array) is a fine-pitch BGA. No lab, no bench, let us go — but you will need a rework station with a bottom heater and a stencil for solder paste. The package is MSL-rated; check the moisture-sensitive label before baking. This is not a socketed part you swap in the field; it is a production-solder device.","metaTitle":"Texas Instruments MSP430F478IZQWR 16-bit MCU, 8 MHz","metaDescription":"Texas Instruments MSP430F478IZQWR 16-bit MCU, 8 MHz core, 48 KB Flash, 2K x 8 RAM, 5x16-bit ADC, 1x12-bit DAC, 113-VFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x4xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, LCD, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"48","Core Processor":"MSP430 CPU16","Package / Case":"113-VFBGA","Product Status":"Obsolete","Data Converters":"A/D 5x16b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F478","Program Memory Size":"48KB (48K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"113-BGA Microstar Junior (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2a12a9cec3fa4ae1bde1fe530182f33b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F478IZQWR/alternatives.json"},"ai":{"faq":[{"question":"What is the exact replacement for MSP430F478IZQWR?","answer":"Texas Instruments does not list a direct pin-compatible replacement for the MSP430F478IZQWR in the current MSP430 portfolio.
