An internal oscillator and a brown-out detect / POR / WDT peripheral set mean it can run standalone in an industrial enclosure with minimal support components. ## 28 I/O and the 48-VQFN footprint The 48-VFQFN with exposed pad (7x7 mm body) is the package you see on a lot of compact motor-drive and PLC-I/O cards. Tape & Reel delivery means it feeds straight into a pick-and-place for volume builds. ## On-site swap reality If you are carrying a field kit and need to swap this on a customer's panel, the 48-VQFN is not socket-friendly — you will need hot air or a rework station to get the exposed pad off the board. No ESD bench? Ground yourself to the enclosure before handling.","metaTitle":"LM3S308-IGZ25-C2T Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"Texas Instruments LM3S308-IGZ25-C2T 32-bit ARM Cortex-M3 MCU at 25 MHz with 16 KB Flash, 4 KB RAM, 28 I/O, industrial temp -40°C to 85°C, 48-VQFN.","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":"Stellaris® ARM® Cortex®-M3S 300","Package":"Tape & Reel (TR)","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"28","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-VFQFN Exposed Pad","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S308","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-VQFN (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/90a978bd331b0d8880daa32faecfc169.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the core speed of LM3S308-IGZ25-C2T?","answer":"The core runs at 25 MHz, which is the maximum clock from the internal oscillator or an external crystal. At this speed, the Flash requires zero wait states for single-cycle access, so interrupt latency stays predictable for control loops."},{"question":"How many I/O pins does LM3S308-IGZ25-C2T have?","answer":"It has 28 general-purpose I/O pins.
