This is a legacy part commonly found in sensor interfaces, low-power data loggers, and simple control loops where the 16-bit core and low pin count keep the BOM lean. Procurement for this part runs through independent distribution and surplus inventory channels. ## Peripheral set and memory — what fits and what does not With 4 KB Flash and 256 bytes of RAM, this part is sized for a single control loop or a small state machine with a UART or SPI link to a host. The 22 I/O lines give enough headroom for a 16-bit parallel LCD bus or a keypad matrix plus a few sensors. The slope A/D is a low-resolution converter — it works for battery monitoring or temperature thresholds but not for precision analog acquisition. ## 28-SOIC wide-body — footprint and storage The supplier device package is 28-SOIC.","metaTitle":"TI MSP430F122IDWR 16-bit MCU, 8MHz, 4KB Flash, 28-SOIC","metaDescription":"Texas Instruments MSP430F122IDWR 16-bit MCU, 8MHz, 4KB Flash, 256B RAM, SPI/UART, -40°C to 85°C, 28-SOIC.","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":"MSP430x1xx","Package":"Tape & Reel (TR)","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":"Obsolete","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":"$1.7000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec6de63ed9468b19219071451a99871b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F122IDWR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430F122IDWR obsolete and can it still be purchased?","answer":"Yes, the MSP430F122IDWR is obsolete per the lifecycle record.
