The 16-bit RISC core draws microamps in standby, which is the whole point of the MSP430 architecture: you trade throughput for battery life. ## 256 bytes RAM — plan your stack carefully 256 x 8 RAM is tight. A single UART buffer of 64 bytes eats a quarter of it. If the application needs any significant call stack, local variables, or interrupt nesting, the firmware engineer will be counting bytes. This part is not for data logging, protocol stacks, or anything that buffers more than a few dozen bytes. It fits a state machine that reads an ADC, checks a threshold, and toggles a GPIO. The internal oscillator means no external crystal is needed for the core clock, saving two pins and a couple of passives. Brown-out detect and the watchdog timer are built in, so the reset circuit can be minimal. It is not automotive-qualified (no AEC-Q100 marking), so it stays out of under-hood or chassis-mounted applications unless the customer accepts non-automotive-grade risk.","metaTitle":"MSP430G2303IPW20 16-bit MCU, 4KB Flash, 256B RAM, 16 MHz","metaDescription":"Texas Instruments MSP430G2303IPW20 16-bit MCU, 4KB Flash, 256B RAM, 16 MHz, -40°C to 85°C, 20-TSSOP.","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":"Tube","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":"16","Core Processor":"MSP430 CPU16","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2303","Program Memory Size":"4KB (4K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1400","priceTiers":[{"qty":1,"price":"$2.14000","currency":"USD"},{"qty":10,"price":"$1.92400","currency":"USD"},{"qty":25,"price":"$1.81520","currency":"USD"},{"qty":100,"price":"$1.54640","currency":"USD"},{"qty":250,"price":"$1.45200","currency":"USD"},{"qty":500,"price":"$1.27050","currency":"USD"},{"qty":1000,"price":"$1.05270","currency":"USD"},{"qty":2500,"price":"$0.98010","currency":"USD"},{"qty":5000,"price":"$0.94380","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/aa1021d14ccf54bbadb16cd01958dd1f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2303IPW20/alternatives.json"},"ai":{"faq":[{"question":"What are the alternatives to MSP430G2303IPW20?","answer":"Within the MSP430G2xx family, higher-density parts with more Flash and RAM share the same 20-pin TSSOP footprint and peripheral set.
