Running a real-time operating system or a USB stack will exhaust the Flash before the first peripheral is configured. The 8 MHz core speed, combined with the 16-bit architecture, delivers enough throughput for periodic ADC reads, PWM generation, and UART communication at standard baud rates. Expect interrupt latency in the sub-microsecond range — adequate for most industrial sensor polling but too slow for high-frequency motor control loops that need tens of kilohertz update rates. The industrial temperature range covers cold-start scenarios and passively cooled enclosures, but it is not qualified for under-hood automotive or downhole drilling environments where 125°C or higher is required. ## Peripheral set and supply rails On-chip peripherals include POR, PWM, and WDT, plus a SPI and UART/USART serial interface. The 22 general-purpose I/O pins give enough headroom for a keypad matrix, a small character LCD, or a handful of discrete sensors.","metaTitle":"Texas Instruments MSP430F122IDW 16-bit MCU, 8 MHz","metaDescription":"Texas Instruments MSP430F122IDW 16-bit MCU, 8 MHz core, 4 KB Flash, 256 B RAM, 22 I/O, SPI/UART, -40°C to 85°C, 28-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x1xx","Package":"Tube","RAM Size":"256 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"POR, PWM, WDT","Connectivity":"SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"22","Core Processor":"MSP430 CPU16","Package / Case":"28-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","Data Converters":"Slope A/D","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F122","Program Memory Size":"4KB (4K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"28-SOIC","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec6de63ed9468b19219071451a99871b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F122IDW/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430F122IDW in this component family?","answer":"Within the MSP430x1xx family, the MSP430F1232IDW offers the same pinout with 8 KB Flash and 256 B RAM.
