Peripheral set includes POR, PWM, and WDT, plus SPI and UART/USART connectivity. ## Memory budget — plan the firmware before you commit 8 KB of Flash and 256 bytes of RAM are tight. A full RTOS kernel or a large lookup table will not fit. The Flash is field-reprogrammable via the internal bootloader or an MSP-FET debug probe, but the RAM limits runtime data buffers to a few hundred bytes. If the application needs more headroom, the MSP430x1xx family offers pin-compatible parts with larger Flash and RAM — though the exact density options vary by suffix.","metaTitle":"Texas Instruments MSP430F123IDW 16-bit MCU, 8 MHz","metaDescription":"Texas Instruments MSP430F123IDW 16-bit MCU with 8 MHz core, 8 KB Flash, 256 B RAM, SPI/UART, industrial -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"MSP430x1xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x1xx","Package":"Tube","RAM Size":"256 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"POR, PWM, WDT","Connectivity":"SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"22","Core Processor":"MSP430 CPU16","Package / Case":"28-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","Data Converters":"Slope A/D","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F123","Program Memory Size":"8KB (8K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"28-SOIC","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.7800","priceTiers":[{"qty":1,"price":"$7.78000","currency":"USD"},{"qty":10,"price":"$6.99100","currency":"USD"},{"qty":25,"price":"$6.60960","currency":"USD"},{"qty":100,"price":"$5.72830","currency":"USD"},{"qty":250,"price":"$5.43456","currency":"USD"},{"qty":500,"price":"$4.87642","currency":"USD"},{"qty":1000,"price":"$4.11264","currency":"USD"},{"qty":2500,"price":"$3.90701","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ec6de63ed9468b19219071451a99871b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F123IDW/alternatives.json"},"ai":{"faq":[{"question":"Can MSP430F123IDW be programmed with MSP-FET?","answer":"Yes, the MSP430F123IDW uses the standard MSP430 Spy-Bi-Wire (SBW) debug interface, which is supported by the MSP-FET programmer/debugger.
