The part integrates a 6-channel 14-bit ADC, a direct-drive LCD controller, a UART/USART serial interface, a power-on reset (POR), and a watchdog timer (WDT). The LCD driver and the 14-bit ADC make this device a fit for metering, instrumentation, and human-interface panels where firmware is finalized before production and field updates are not required. ## OTP memory means no field updates The 16 KB program memory is OTP (one-time programmable). Once the device is programmed, the code cannot be erased or rewritten. This locks the firmware at the factory, so any bug fix, feature change, or calibration update requires a new device. For production, this means the firmware must be validated thoroughly before programming. For sourcing, OTP parts are typically programmed by the distributor or a programming house before shipment; verify that your supply chain supports this step. The 512 x 8 RAM is small — budget for interrupt service routines and stack depth; a deep call tree or large local variables will overflow quickly. The MSP430P325AIPM is marked as Obsolete by Texas Instruments. New designs should not target this part. Because OTP parts are programmed before shipment, verify that any stock you source is either unprogrammed (blank) or matches your firmware image exactly — a programmed part with different code is scrap.","metaTitle":"TI MSP430P325AIPM 16-bit MCU, 8 MHz, OTP, 64-LQFP","metaDescription":"Texas Instruments MSP430P325AIPM 16-bit MCU, 8 MHz core, 16 KB OTP program memory, 512 x 8 RAM, 6x14-bit ADC, LCD driver, -40°C to 85°C, 64-LQFP.","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":"512 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"LCD, POR, WDT","Connectivity":"UART/USART","Mounting Type":"Surface Mount","Number of I/O":"14","Core Processor":"MSP430 CPU16","Package / Case":"64-LQFP","Product Status":"Obsolete","Data Converters":"A/D 6x14b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430P325","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"OTP","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2.5V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/686e7ac6e8e62a7f9892503269cd677c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430P325AIPM/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MSP430P325AIPM?","answer":"The evidence does not list an official replacement or successor for the MSP430P325AIPM. Because the part uses OTP memory and integrates an LCD driver and 14-bit ADC, a direct pin-compatible substitute is unlikely. For new designs, consider a current MSP430 family member with Flash memory and similar peripheral set, but verify the package and pinout — a board layout change may be required."},{"question":"Where can I buy MSP430P325AIPM?","answer":"The MSP430P325AIPM is obsolete and not available through authorized distribution.
