The 100-LQFP package (14x14 mm) provides 52 GPIOs, enough for a mixed-signal control board with parallel LCD or keypad matrix. That means the board's LDO or DC-DC must hold the rail within 200 mV of 2.5 V, which rules out a simple 3.3 V rail and a series resistor. Plan for a dedicated 2.5 V regulator with ±10% tolerance. Texas Instruments has ended production; no last-time-buy window remains open through the factory.","metaTitle":"LM3S2608-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S2608-EQC50-A2T Stellaris ARM Cortex-M3 MCU: 50 MHz, 128 KB Flash, 32 KB RAM, CAN/I²C/SPI/UART, -40°C to 105°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tape & Reel (TR)","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2608","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a2ff937540c4d13996596b9d7b90b705.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2608-EQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2608-EQC50-A2T obsolete?","answer":"Yes, the LM3S2608-EQC50-A2T is listed as Obsolete.
