With 1 KB of Flash, the firmware image must be lean — think a few hundred lines of C for a temperature monitor, a simple PWM fan controller, or a battery-charge state machine. The 128 bytes of RAM handle a small call stack and a handful of variables; any data logging or buffering beyond a few bytes will overflow. This part is not for complex protocol stacks or multi-tasking kernels. It fits where an 8-bit MCU might go but brings the 16-bit MSP430 architecture's lower active power and better C-code efficiency. Housed in a 16-pin VQFN with exposed pad (4x4 mm body), this package is compact but reworkable with a hot-air station if you pre-bake per MSL requirements. For dual-sourcing resilience, the MSP430G2xx family includes several pin-compatible density variants — the MSP430G2231 (2 KB Flash) and MSP430G2452 (8 KB Flash) share the same 16-QFN footprint and peripheral set, allowing a BOM upgrade without a board spin if the firmware grows.","metaTitle":"MSP430G2152IRSA16R 16-bit MCU, 16 MHz, 1 KB Flash, 16-QFN","metaDescription":"Texas Instruments MSP430G2152IRSA16R 16-bit MCU with 16 MHz core, 1 KB Flash, 128 B RAM, 10 I/O, 8x10b ADC, I²C/SPI/USI, -40 to 85°C, active.","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, DMA, POR, PWM, WDT","Connectivity":"I²C, SPI, USI","Mounting Type":"Surface Mount","Number of I/O":"10","Core Processor":"MSP430 CPU16","Package / Case":"16-VQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2152","Program Memory Size":"1KB (1K 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":"$0.7459","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8acb3ddcf2d6da6c182cb35a69f021be.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2152IRSA16R/alternatives.json"},"ai":{"faq":[{"question":"Does MSP430G2152IRSA16R have an internal oscillator?","answer":"Yes, the oscillator type is internal, so no external crystal or resonator is required for basic clocking."},{"question":"How many I/O pins does MSP430G2152IRSA16R have?","answer":"It has 10 I/O pins, which includes the pins shared with the ADC and USI peripheral functions."},{"question":"What is the closest pin-compatible alternative to MSP430G2152IRSA16R in the MSP430G2xx family?","answer":"The MSP430G2231 (2 KB Flash) and MSP430G2452 (8 KB Flash) share the same 16-QFN footprint, supply range, and peripheral set, offering a firmware-upgrade path without a PCB change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430G2152IRSA16R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430G2152IRSA16R when reusing this data.
