The 4 KB RAM supports a few hundred bytes of stack plus moderate-sized data buffers for UART or SPI transactions. For designs that need more memory headroom, the Stellaris family offers pin-compatible density upgrades without a board respin. ## Package and board-level fit The 48-VFQFN exposed pad package (7x7 mm body) needs a via-stitched thermal land on the PCB for heat dissipation. For dual-sourcing or supply resilience, the Stellaris family includes multiple density and package variants that share the same Cortex-M3 core and peripheral set, though pin compatibility should be verified against the specific ordering code.","metaTitle":"TI LM3S310-EGZ25-C2 ARM Cortex-M3 MCU, 25 MHz, 16 KB Flash","metaDescription":"Texas Instruments Stellaris LM3S310-EGZ25-C2: 32-bit ARM Cortex-M3 MCU at 25 MHz, 16 KB Flash, 4 KB RAM, 36 I/O, -40 to 105°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":"Tray","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"36","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-VFQFN Exposed Pad","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S310","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°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/bdef0478df91eed4b7a3abae6c372c23.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the LM3S310-EGZ25-C2 and what is the lead time?","answer":"This part is sourced to order through independent distribution against an RFQ.
