The 1K x 8 RAM is tight by modern standards; designs that needed larger data buffers or dynamic firmware patching would have hit the ceiling quickly. ## Peripheral set: LCD and slope A/D targeted metering and display The integrated LCD driver and slope A/D converter were the distinguishing features of this MSP430x3xx variant — it was designed for applications like utility meters, thermostats, and panel instruments that needed a local display and basic analog measurement without external components. The 40 I/O pins in a 100-BQFP package gave enough headroom for segmented displays and keypad scanning. ## 8 MHz core — adequate for its era, limited for new designs At 8 MHz the CPU16 core delivered modest throughput, but the MSP430 architecture's low-power efficiency meant it could run from a coin cell in sleep-heavy metering applications. For any new design requiring higher throughput or field reprogrammability, a current MSP430 FRAM or MSPM0 series part would be the practical migration path. ## Sourcing reality for an obsolete part The MSP430P337AIPJM is officially obsolete per the manufacturer's product status. Availability is limited to independent-distribution surplus and last-time-buy inventory.","metaTitle":"Texas Instruments MSP430P337AIPJM 16-bit MCU, 8MHz, 32KB OTP","metaDescription":"MSP430P337AIPJM is an obsolete 16-bit MSP430 MCU with 8MHz core, 32KB OTP program memory, 1K x 8 RAM, LCD driver, slope A/D, SPI/UART.","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":"Tray","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/MSP430P337AIPJM/alternatives.json"},"ai":{"faq":[{"question":"Can MSP430P337AIPJM be programmed with MSP430 flash tools?","answer":"No — the MSP430P337AIPJM uses OTP (one-time programmable) memory, not flash. Standard MSP430 flash programming tools are not compatible. Programming requires a device programmer that supports the MSP430x3xx OTP family, typically a gang programmer or a dedicated OTP programming adapter."},{"question":"What is the replacement for MSP430P337AIPJM?","answer":"There is no official pin-compatible replacement listed in the manufacturer's lifecycle record. For new designs, a current MSP430 FRAM series MCU (e.g., MSP430FRxx) or the newer MSPM0 family would be the practical migration path, though a full board redesign and firmware port will be required due to differences in package, peripheral set, and memory architecture."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430P337AIPJM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430P337AIPJM when reusing this data.
