It packs 16 KB of on-chip Flash and 4K x 8 bytes of SRAM, enough for a modest control loop or sensor fusion task without external memory. ## Package, temperature grade, and board-fit The internal oscillator means you can skip an external crystal for many applications, saving two pins and a couple of passives — though if you need tight timing for a UART baud rate, you'll still want a resonator. ## On-chip peripherals and serial connectivity Beyond the serial interfaces, the MCU includes a brown-out detect/reset, a power-on reset, a PWM module, and a watchdog timer — enough to build a simple motor controller or a safety watchdog without an external supervisor IC. The 16 KB Flash and 4 KB SRAM budget is tight for a full RTOS but comfortable for a bare-metal state machine or a lightweight scheduler like protothreads.","metaTitle":"Texas Instruments LM3S300-EGZ25-C2T Stellaris Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S300-EGZ25-C2T Stellaris ARM Cortex-M3 MCU, 25MHz, 16KB Flash, 4K x 8 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":"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":"36","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-VFQFN Exposed Pad","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S300","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/b0079ff5b3d77e4f86c3abfcf8857684.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM3S300-EGZ25-C2T in this Stellaris family?","answer":"Within the Stellaris® ARM® Cortex®-M3S 300 series, the LM3S301 and LM3S310 variants share the same 48-VQFN footprint and pinout but offer different Flash/RAM combinations.
