The 72 GPIOs in a 100-LQFP package leave enough headroom for a parallel LCD data bus alongside a keypad matrix and sensor interfaces. Its dual ADC block — 8 channels of 10-bit successive-approximation plus 3 channels of 24-bit sigma-delta — is the main differentiator versus smaller MSP430 derivatives. The 24-bit channels resolve microvolt-level signals from bridge sensors or thermocouples without an external amplifier, while the 10-bit SAR handles faster multiplexed scans for system monitoring. ## Industrial temp range and single-supply operation The internal oscillator eliminates the external crystal for many applications, though the I²C, SPI, UART, LINbus, and IrDA interfaces remain available for wired sensor buses. The brown-out detect and POR peripherals ensure a clean reset on power-up and during supply dips — critical for battery-powered instruments where the rail decays slowly.","metaTitle":"TI MSP430A155IPZ 16-bit MCU, 25 MHz, 64 KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430A155IPZ 16-bit MCU, 25 MHz, 64 KB Flash, 4 KB RAM, LCD/DMA/PWM, dual ADC (8×10b + 3×24b), -40 to 85 °C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F6xx","Package":"Tray","RAM Size":"4K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"72","Core Processor":"MSP430","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 8x10b, 3x24b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430A155","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.6918","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4d6497d44b37ad9be23ad8aca111200b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430A155IPZ/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430A155IPZ?","answer":"The MSP430F6xx family includes other 100-LQFP devices with similar peripheral sets (LCD, DMA, dual ADC), but the exact memory and ADC configuration differs per variant.
