No last-time-buy window remains open. The base product number is LM3S1N11; the IBZ50 suffix identifies the 108-BGA package and 50 MHz speed grade, while C3T indicates tape-and-reel packaging. ## Cortex-M3 core with 50 MHz and 64 KB flash The 64 KB on-chip flash (64K x 8) and 12K x 8 SRAM provide enough code and data space for moderate-complexity control applications such as motor drives, human-machine interfaces, or sensor hubs. Connectivity options include I²C, SPI, SSI, UART/USART, IrDA, LINbus, and Microwire — enough serial interfaces to handle multiple sensor buses, a debug UART, and a display link simultaneously. The 67 GPIOs are available on the 108-ball BGA package (10x10 mm), which is a compact footprint for space-constrained PCBs. On-chip peripherals include a brown-out detect/reset, DMA controller, POR, PWM outputs, and a watchdog timer. The 8-channel 10-bit ADC handles analog inputs like potentiometers or current-sense resistors without an external converter.","metaTitle":"LM3S1N11-IBZ50-C3T Texas Instruments Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S1N11-IBZ50-C3T Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 12K x 8 RAM, 108-BGA.","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":"Tape & Reel (TR)","RAM Size":"12K 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":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1N11","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/382ae1f60fbe7febad9e9e5bf72a2bb6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1N11-IBZ50-C3T/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the LM3S1N11-IBZ50-C3T?","answer":"A board spin may be required to migrate to a current Stellaris or Tiva-C series MCU with similar core and peripheral count."},{"question":"What is the LM3S1N11-IBZ50-C3T's core speed and memory?","answer":"The ARM Cortex-M3 core runs at 50 MHz.
