At this speed, a typical PID loop or UART polling routine executes with single-cycle instruction fetch from the 16 KB Flash, assuming zero wait states. The 512 x 8 RAM (512 bytes) is the scratchpad — enough for small data buffers and stack frames in a sensor node or keypad controller, but tight for any protocol buffering beyond a few dozen bytes. The I²C and SPI modules are independent hardware peripherals, so simultaneous operation on both buses is supported without bit-banging. The 12-channel 10-bit ADC (A/D 12x10b) samples analog inputs from the 32 available I/O pins, enough for multi-sensor acquisition in a thermostat or motor feedback circuit. ## Package and temperature grade: 40-VQFN, industrial range Housed in a 40-VFQFN with exposed pad (supplier package 40-VQFN 6x6 mm), this is a surface-mount part intended for reflow assembly.","metaTitle":"MSP430G2544IRHA40R 16-bit MCU, 16 MHz, 16 KB Flash, 40-VQFN","metaDescription":"Texas Instruments MSP430G2544IRHA40R 16-bit MCU, 16 MHz, 16 KB Flash, 512 B RAM, I2C/SPI/UART, -40°C to 85°C, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430G2xx","Package":"Tape & Reel (TR)","RAM Size":"512 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"32","Core Processor":"MSP430 CPU16","Package / Case":"40-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 12x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2544","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"40-VQFN (6x6)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8003","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fecf014f6a31b9f07bed9857b04b4a93.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2544IRHA40R/alternatives.json"},"ai":{"faq":[{"question":"Does MSP430G2544IRHA40R support I2C and SPI simultaneously?","answer":"Yes.
