This part is aimed at industrial control, metering, and human-machine interface applications where the firmware is locked at the factory and field updates are not needed. ## 32KB OTP — no field updates possible The program memory is OTP (one-time programmable), meaning once the device is programmed, the code cannot be changed. This is a deliberate choice for high-volume production where firmware is mature and field updates are not required. For prototyping or designs that may need firmware patches, a Flash-based MSP430 sibling would be the better fit. The OTP decision also affects the supply chain: the part must be programmed before assembly, typically by a programming house or in-house with a gang programmer, and any code change means scrapping the programmed devices.","metaTitle":"TI MSP430P337AIPJMR 16-bit MCU, 8MHz, 32KB OTP, 100-QFP","metaDescription":"Texas Instruments MSP430P337AIPJMR 16-bit MCU, 8MHz MSP430 CPU16, 32KB OTP, 1KB SRAM, 40 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x3xx","Package":"Tape & Reel (TR)","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"LCD, POR, PWM, WDT","Connectivity":"SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"40","Core Processor":"MSP430 CPU16","Package / Case":"100-BQFP","Product Status":"Obsolete","Data Converters":"Slope A/D","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430P337","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"OTP","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-QFP (20x14)","Voltage - Supply (Vcc/Vdd)":"2.5V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/340afbe1427ba25f4b7b58726f9a4619.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430P337AIPJMR/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy MSP430P337AIPJMR?","answer":"Submit an RFQ for current availability and pricing — we confirm both at quote time.
