Having both CAN and Ethernet on a single die at 50 MHz means this part can serve as a protocol bridge in a distributed control network without an external communication co-processor. The 36 general-purpose I/O lines, plus an 8-channel 10-bit ADC, cover sensor readout and actuator drive for most panel-mount or DIN-rail equipment. ## Lifecycle reality: obsolete, not dead Texas Instruments has ended production of this Stellaris family MCU. ## Memory and performance for the task The 50 MHz Cortex-M3 runs at 50 MHz. The 64 KB SRAM and 96 KB FLASH support a TCP/IP stack and application data. The internal oscillator reduces external component count. The 100-LQFP (14x14 mm) package is a standard quad flat pack.","metaTitle":"LM3S8538-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S8538-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz, 96KB Flash, 64KB SRAM, CANbus/Ethernet, -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 8000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, Ethernet, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"36","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":"LM3S8538","Program Memory Size":"96KB (96K 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":"Does LM3S8538-EQC50-A2T have ethernet?","answer":"Yes, the LM3S8538-EQC50-A2T includes an Ethernet MAC controller on-chip, enabling direct connection to 10/100 Ethernet networks with an external PHY."},{"question":"What is the replacement for LM3S8538-EQC50-A2T?","answer":"Texas Instruments has not listed an official replacement for this obsolete Stellaris MCU.
