The 8 KB Flash is the entire program store — no external memory interface, so the firmware image must fit entirely in that space. The 256-byte RAM is the working set: stack, global variables, and a small FIFO. That rules out any application needing a large lookup table, a real-time OS with multiple task stacks, or a TCP/IP stack. For a single-ended UART polling loop or an I²C sensor readout, it's enough — but the linker map needs watching. ## Peripherals and connectivity on a 20-pin DIP The internal oscillator means no external crystal is needed for basic operation — useful for a minimal BOM count in a low-cost sensor node.","metaTitle":"Texas Instruments MSP430G2432IN20 16-Bit MCU, 16MHz","metaDescription":"Texas Instruments MSP430G2432IN20 16-bit MCU with 16MHz CPU, 8KB Flash, 256B RAM, 16 I/O, 8x10-bit ADC, I²C/SPI/USI, industrial temp -40°C to 85°C, 20-DIP","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, DMA, POR, PWM, WDT","Connectivity":"I²C, SPI, USI","Mounting Type":"Through Hole","Number of I/O":"16","Core Processor":"MSP430 CPU16","Package / Case":"20-DIP (0.300\\\", 7.62mm)","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2432","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-PDIP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3000","priceTiers":[{"qty":1,"price":"$3.30000","currency":"USD"},{"qty":10,"price":"$2.96700","currency":"USD"},{"qty":25,"price":"$2.79920","currency":"USD"},{"qty":100,"price":"$2.38470","currency":"USD"},{"qty":250,"price":"$2.23920","currency":"USD"},{"qty":500,"price":"$1.95930","currency":"USD"},{"qty":1000,"price":"$1.62342","currency":"USD"},{"qty":2500,"price":"$1.51146","currency":"USD"},{"qty":5000,"price":"$1.45548","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/60ac4c619fe70e0fb4fb2fb2f00e3c97.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2432IN20/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between the MSP430G2432 and the MSP430G2452?","answer":"The MSP430G2452 is a pin-compatible sibling in the same MSP430G2xx family. The primary difference is program memory: the G2432 has 8 KB Flash, while the G2452 carries 8 KB as well (same density). The real differentiator is the peripheral set — the G2452 adds a comparator and a higher-resolution ADC in some variants.
