The 8-channel 10-bit ADC samples analog inputs like thermistors or potentiometers without an external converter. ## Active lifecycle — no EOL risk for production builds That means no last-time-buy window to manage, no forced redesign for a replacement. For dual-sourcing or higher-performance needs, the MSP430G2553 is a common sibling in the same G2xx family with more Flash and RAM, but the G2433 remains a cost-optimized entry point for 8 KB designs. ## 16 I/O and 20-TSSOP — layout and rework notes The 0.65 mm pitch is fine enough for a two-layer board but needs careful soldermask definition.","metaTitle":"MSP430G2433IPW20 16-bit MCU, 16 MHz, 8 KB Flash, 20-TSSOP","metaDescription":"Texas Instruments MSP430G2433IPW20 16-bit MCU with 16 MHz core, 8 KB Flash, 512x8 RAM, 1.8-3.6V supply, industrial temp -40°C to 85°C.","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":"512 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":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2433","Program Memory Size":"8KB (8K 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":"$3.5200","priceTiers":[{"qty":1,"price":"$3.52000","currency":"USD"},{"qty":10,"price":"$3.16100","currency":"USD"},{"qty":25,"price":"$2.98200","currency":"USD"},{"qty":100,"price":"$2.54070","currency":"USD"},{"qty":250,"price":"$2.38560","currency":"USD"},{"qty":500,"price":"$2.08740","currency":"USD"},{"qty":1000,"price":"$1.72956","currency":"USD"},{"qty":2500,"price":"$1.61028","currency":"USD"},{"qty":5000,"price":"$1.55064","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/aa1021d14ccf54bbadb16cd01958dd1f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2433IPW20/alternatives.json"},"ai":{"faq":[{"question":"Can MSP430G2433IPW20 be used in battery-powered applications?","answer":"Yes. The 16-bit MSP430 core is designed for low power consumption, with multiple sleep modes that draw microamps, making it a good fit for battery-powered sensor nodes and portable devices."},{"question":"What programming tools support MSP430G2433IPW20?","answer":"The MSP430G2433IPW20 is programmed and debugged via the standard Spy-Bi-Wire (SBW) two-wire interface, supported by TI's MSP-FET programmer, the LaunchPad development boards, and third-party tools like the Segger J-Link. The SBW interface uses the TEST and RST pins, so reserve those on your PCB."},{"question":"What is the difference between MSP430G2433IPW20 and MSP430G2553?","answer":"The MSP430G2553 is a higher-density sibling in the same G2xx family, offering up to 16 KB Flash and 512 bytes RAM versus the G2433's 8 KB Flash and 512 x 8 RAM. The G2553 also adds a second 16-bit timer and a comparator. Both are pin-compatible in the 20-TSSOP package, so a firmware-only migration is possible if the extra memory is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430G2433IPW20","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430G2433IPW20 when reusing this data.
