The peripheral list includes CAN, USB, UART, SPI, I2C, LIN, and a quadrature encoder interface, so it can sit in an industrial drive or an automotive body controller without glue logic. ## Industrial temperature, single-core, 1.08 V to 1.32 V core supply The core runs from a 1.08 V to 1.32 V supply, so the board needs a dedicated low-voltage rail. TI lists this device as obsolete. That means the only channel is the surplus and broker market. ## 10-bit ADC and DMA for sensor fusion Sixteen 10-bit ADC channels sample analog inputs from current sensors, thermistors, or potentiometers. The DMA engine moves data without CPU intervention, which matters when the 80 MHz core is busy with CAN message handling or USB packet processing.","metaTitle":"LM3S5P31-IQC80-C3 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S5P31-IQC80-C3 Stellaris ARM Cortex-M3 MCU, 80MHz core, 64KB Flash, 24K x 8 RAM, -40°C to 85°C industrial temp, 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":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 5000","Package":"Tray","RAM Size":"24K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5P31","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 1.32V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6eb0e448a2435bd671cb24636bc93dca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5P31-IQC80-C3/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S5P31-IQC80-C3 obsolete?","answer":"Yes, TI lists the LM3S5P31-IQC80-C3 as obsolete.
