The 16 MHz clock allows tight timing for bit-banged protocols or PWM generation, but the firmware must fit within the 2 KB program memory — no room for a full RTOS or large lookup tables. The 256-byte RAM limits stack depth and buffer sizes; careful allocation is needed for interrupt service routines and serial data handling. The brown-out detect resets the core cleanly during supply droop, critical for battery-operated systems. ## Package and footprint — 32-VFQFN with exposed pad The supplier device package is 32-VQFN (5x5). It is ROHS3 compliant.","metaTitle":"MSP430G2203IRHB32T 16-Bit MCU, 2KB Flash, 16 MHz, 32-VQFN","metaDescription":"Texas Instruments MSP430G2203IRHB32T 16-bit MCU, 16 MHz, 2KB Flash, 256B RAM, I²C/SPI/UART, -40°C 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, 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":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2203","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":"$2.8900","priceTiers":[{"qty":1,"price":"$2.89000","currency":"USD"},{"qty":10,"price":"$2.59500","currency":"USD"},{"qty":25,"price":"$2.44800","currency":"USD"},{"qty":100,"price":"$2.08570","currency":"USD"},{"qty":250,"price":"$1.95840","currency":"USD"},{"qty":500,"price":"$1.71360","currency":"USD"},{"qty":1250,"price":"$1.41984","currency":"USD"},{"qty":2500,"price":"$1.32192","currency":"USD"},{"qty":6250,"price":"$1.27296","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a2be46819bdc521a7182d43a0d5cd6a3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2203IRHB32T/alternatives.json"},"ai":{"faq":[{"question":"What is MSP430G2203IRHB32T's listed speed?","answer":"The core processor runs at 16 MHz, which is the maximum clock frequency supported by the internal oscillator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430G2203IRHB32T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430G2203IRHB32T when reusing this data.
