The Flash holds the compiled firmware image; a typical MSP430G2xx interrupt vector table and startup code consumes about 32 to 64 bytes, leaving roughly 450 bytes for the application loop, peripheral initialization, and any lookup tables. The 128-byte RAM must cover stack, global variables, and interrupt context — a single 64-byte buffer eats half the budget. If your firmware fits within these limits, the MSP430G2001IRSA16R delivers the lowest active power in the MSP430G2xx lineup, with a typical active-mode draw around 220 µA at 1 MHz and 2.2 V. For designs that need more headroom, the MSP430G2x13 or G2x53 siblings offer 1 KB to 8 KB Flash and 128 to 512 bytes RAM in the same 16-QFN footprint. ## Package and mounting: 16-QFN with exposed pad The part comes in a 16-VQFN Exposed Pad package (supplier device package 16-QFN, 4x4 mm). The QFN footprint is compact, but the 0.5 mm pitch and the center pad require a stencil with good paste coverage to avoid voids.","metaTitle":"TI MSP430G2001IRSA16R 16-bit MCU, 16 MHz, 512B Flash","metaDescription":"Texas Instruments MSP430G2001IRSA16R 16-bit MCU, 16 MHz core, 512B Flash, 128B RAM, 10 I/O, 1.8V-3.6V, -40°C to 85°C, QFN-16.","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":"MSP430G2xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"128 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":"10","Core Processor":"MSP430 CPU16","Package / Case":"16-VQFN Exposed Pad","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2001","Program Memory Size":"512B (512 x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"16-QFN (4x4)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6972","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/937fce24b59bfba17c8b94ce6eb9d6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2001IRSA16R/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430G2001IRSA16R a good replacement for MSP430G2001IPW?","answer":"The MSP430G2001IPW is the TSSOP-16 package variant of the same die. They are electrically identical — same core, memory, peripherals, and supply range — but the footprint and thermal behavior differ. The QFN version offers a smaller PCB area and better thermal dissipation through the pad, but requires a different land pattern and stencil design. If your board layout can accommodate either package, the IRSA16R is a drop-in functional replacement for the IPW after adjusting the footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430G2001IRSA16R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430G2001IRSA16R when reusing this data.
