The 4 KB Flash is the hard limit for compiled code — expect to fit a bootloader, a UART command parser, and a few hundred lines of application logic, but not a full RTOS or a TCP/IP stack. The 256 bytes of RAM means careful allocation: a 128-byte buffer plus a few global variables leaves little headroom for stack-heavy functions. It is not AEC-Q100 qualified, so it is not the first choice for under-hood automotive or engine-bay applications, but it works in cabin or chassis domains where the temperature stays within the industrial band.","metaTitle":"TI MSP430F2121IDGV 16-Bit MCU, 16 MHz, 4 KB Flash, 20-TFSOP","metaDescription":"Texas Instruments MSP430F2121IDGV 16-bit MCU, 16 MHz core, 4 KB Flash, 256 B RAM, 1.8 V to 3.6 V supply, -40°C to 85°C, 20-TFSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430F2xx","Package":"Tray","RAM Size":"256 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"-","Mounting Type":"Surface Mount","Number of I/O":"16","Core Processor":"MSP430 CPU16","Package / Case":"20-TFSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"Slope A/D","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F2121","Program Memory Size":"4KB (4K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-TVSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3332","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/915f3387ecbce04a8fd7c7e9a4da9617.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F2121IDGV/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430F2121IDGV in this component family?","answer":"The MSP430F2121IDGV is pin-compatible with other MSP430F2xx devices in the same 20-pin TFSOP package, such as the MSP430F2121IPW (same die in a TSSOP package).
