The 80 MHz core delivers enough throughput for a control loop with sensor acquisition, a protocol stack (TCP/IP or CANopen), and local decision logic. The 60 GPIOs in the 100-LQFP package give the board designer pin budget for parallel LCD interfaces, keypad matrices, or multiple chip-select lines without a port expander. ## Industrial temperature grade and peripheral set The 16-channel 12-bit ADC captures analog signals from multiple sensors — thermistors, pressure transducers, current shunts — without an external multiplexer. The internal oscillator eliminates the external crystal for the main clock, saving two pins and a board component, though an external source can still drive the PLL for tighter timing accuracy. The 100-LQFP (14x14 mm) footprint uses 0.50 mm pitch, which is reworkable with a standard hot-air station and inspectable under a microscope. For a BOM line already qualified to this MCU, the sourcing strategy is to secure remaining inventory through independent distribution. No factory last-time-buy window remains open.","metaTitle":"TI LM3S1C58-IQC80-A1 Cortex-M3 MCU, 80 MHz, 512 KB Flash","metaDescription":"Texas Instruments LM3S1C58-IQC80-A1 Stellaris ARM Cortex-M3 MCU, 80 MHz, 512 KB Flash, 64 KB SRAM, 60 GPIO, 16-ch 12-bit ADC.","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 1000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1C58","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5b3e46e7d240a1f47e57804cae735c76.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM3S1C58-IQC80-A1?","answer":"Texas Instruments has not published an official pin-compatible successor for this part.
