A typical interrupt service routine with a few local variables can consume 20–40 bytes of stack; a UART receive buffer of 64 bytes leaves about 150 bytes for the main loop's working set. This part is not suited for large data arrays, TCP/IP stacks, or multi-level state machines with deep call trees. It fits best in applications where the firmware fits in a few hundred bytes of code and uses register-based or single-buffer I/O. TI has not issued a last-time-buy notice or end-of-life notification for this device as of the current record. ## Package and thermal pad — what the layout sees The exposed pad also serves as the ground return for the core and I/O — the layout should connect it to the ground plane with multiple vias to keep the inductance low.","metaTitle":"MSP430G2253IRHB32T 16-bit MCU, 16 MHz, 2 KB Flash, 32-VQFN","metaDescription":"Texas Instruments MSP430G2253IRHB32T 16-bit MCU, 16 MHz, 2 KB Flash, 256 B RAM, 1.8-3.6 V, -40 to 85 °C, 32-VQFN.","metaKeywords":null},"attributes":{"series":"MSP430G2xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"256 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"24","Core Processor":"MSP430 CPU16","Package / Case":"32-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2253","Program Memory Size":"2KB (2K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"32-VQFN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2100","priceTiers":[{"qty":1,"price":"$2.21000","currency":"USD"},{"qty":10,"price":"$1.98400","currency":"USD"},{"qty":25,"price":"$1.87200","currency":"USD"},{"qty":100,"price":"$1.59490","currency":"USD"},{"qty":250,"price":"$1.49760","currency":"USD"},{"qty":500,"price":"$1.31040","currency":"USD"},{"qty":1250,"price":"$1.08576","currency":"USD"},{"qty":2500,"price":"$1.01088","currency":"USD"},{"qty":6250,"price":"$0.97344","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3d71879787f17220358164ce00b183ce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2253IRHB32T/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430G2253IRHB32T obsolete or end-of-life?","answer":"No. It remains a current-production device suitable for new designs."},{"question":"What are the alternative parts to MSP430G2253IRHB32T?","answer":"The peer F280041PZQR is a 32-bit C2000 C28x MCU running at 100 MHz with 12-bit ADC and automotive qualification — it targets a different performance and price tier.
