A firmware engineer needs to account for the call stack, interrupt context saves, and any I²C or SPI transmit/receive buffers within that budget. With 10 general-purpose I/O pins on a 16-pin package, the MSP430G2252IRSA16R leaves six pins for power, ground, and the exposed thermal pad. The I/O count is enough for a few sensor inputs, a serial bus, and a couple of control outputs, but any design needing more than 10 GPIOs should look at the higher-pin-count variants in the MSP430G2xx family. There is no NRND notice, no last-time-buy window, and no announced obsolescence.","metaTitle":"TI MSP430G2252IRSA16R 16-bit MCU, 16MHz, 2KB Flash, 16-QFN","metaDescription":"Texas Instruments MSP430G2252IRSA16R 16-bit MCU, 16MHz core, 2KB Flash, 256B RAM, 10 I/O, 8ch 10-bit ADC, -40 to 85°C, 16-QFN.","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)","RAM Size":"256 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":"MSP430G2252","Program Memory Size":"2KB (2K 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":"$0.8570","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8acb3ddcf2d6da6c182cb35a69f021be.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2252IRSA16R/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum clock frequency of MSP430G2252IRSA16R?","answer":"The MSP430G2252IRSA16R runs at a maximum clock speed of 16 MHz.
