For a typical application — say, a temperature transmitter reading the ADC, running a PID loop, and outputting a 4-20 mA DAC signal with Modbus RTU over UART — this is adequate. It does not leave room for a full RTOS or a TCP/IP stack; the firmware stays bare-metal or uses a lightweight scheduler. The 512-byte RAM is the data memory limit, so look-up tables and large buffers need to live in Flash or be streamed. ## Peripherals and I/O count With 48 I/O lines in a 64-LQFP package, there is enough pinout for a parallel LCD, a keypad matrix, or a bank of optocoupled inputs alongside the serial interfaces. The ROHS3 compliance covers EU regulatory requirements without a waiver.","metaTitle":"TI MSP430F155IPM 16-bit MCU, 16KB Flash, 8MHz, 64-LQFP","metaDescription":"Texas Instruments MSP430F155IPM 16-bit MCU with 16KB Flash, 8MHz CPU, 512B RAM, 48 I/O, 12-bit ADC/DAC, -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":"Tray","RAM Size":"512 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"48","Core Processor":"MSP430 CPU16","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 8x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F155","Program Memory Size":"16KB (16K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.7800","priceTiers":[{"qty":1,"price":"$17.78000","currency":"USD"},{"qty":10,"price":"$16.34200","currency":"USD"},{"qty":25,"price":"$15.66440","currency":"USD"},{"qty":160,"price":"$13.80156","currency":"USD"},{"qty":320,"price":"$13.12416","currency":"USD"},{"qty":480,"price":"$12.27744","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/eb54a0334359f82a23bc86a5655b7764.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F155IPM/alternatives.json"},"ai":{"faq":[{"question":"What is the exact flash memory size of MSP430F155IPM?","answer":"The program memory is 16 KB, organized as 16K x 8 bits plus an additional 256 bytes.
