Texas Instruments has discontinued the Stellaris family and no longer manufactures the LM3S5P3B-IBZ80-C5. Date-code provenance and authenticity screening are critical when buying from this channel — verify the PCN timeline and request traceable stock. ## 64 KB Flash and 24 KB SRAM — sizing the firmware budget The 24 KB SRAM is adequate for a few packet buffers and a modest heap, but consider external SRAM or a larger-memory sibling if your design requires significant data buffering. The 80 MHz core executes from Flash with wait states; the memory map and prefetch buffer details are in the datasheet for timing closure. ## 108-ball BGA — footprint and assembly notes The 108-LFBGA package measures 10x10 mm. It requires multi-layer PCB routing and X-ray inspection after reflow.","metaTitle":"LM3S5P3B-IBZ80-C5 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"Texas Instruments LM3S5P3B-IBZ80-C5 is a 32-bit ARM Cortex-M3 MCU at 80 MHz with 64 KB Flash, 24 KB SRAM, CAN/USB, 67 I/O.","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, I²S, 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":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5P3B","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 ~ 1.32V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e170c9265950f6bd18c989aa04fd562.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5P3B-IBZ80-C5/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S5P3B-IBZ80-C5?","answer":"There is no official direct replacement or successor order code from Texas Instruments for the LM3S5P3B-IBZ80-C5. The entire Stellaris ARM Cortex-M3 series is discontinued. A migration to a current TI MCU family (such as the TM4C or MSP432 series) would require a redesign, as the pinout, peripheral set, and voltage supply differ.
