If your firmware image approaches 48 KB compiled, you will be tight on headroom for field-update staging. ## Peripheral set for industrial control The 52 GPIOs give enough headroom for a keypad, display, and a handful of sensors without an external port expander. Internal oscillator means one less BOM line, though a precision crystal is still recommended if you need tight baud-rate accuracy on the UARTs. TI lists the LM3S1150-EQC50-A2 as obsolete. No last-time-buy window remains open through the factory channel. For legacy BOM lines already in production, we can support bridge buys while you migrate.","metaTitle":"LM3S1150-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1150-EQC50-A2 is a 32-bit ARM Cortex-M3 MCU from TI's Stellaris series. 50 MHz core, 64 KB Flash, 16 KB SRAM, 52 I/O, industrial temp -40°C to 105°C.","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 1000","Package":"Tray","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, Microwire, QEI, 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":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1150","Program Memory Size":"64KB (64K 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is the LM3S1150-EQC50-A2 obsolete?","answer":"Yes, TI lists the LM3S1150-EQC50-A2 as obsolete.
