The 2 KB EEPROM allows parameter storage without external serial memory — useful for calibration constants or node address retention across power cycles. ## CANbus and USB OTG — network-ready for industrial and automotive buses With CANbus, USB OTG, and multiple UART/SPI/I²C ports, this MCU can serve as a gateway node between a CAN-based sensor network and a USB-connected host, or as a multi-protocol bridge in a distributed control system. The 69 I/O pins provide ample GPIO for local sensing and actuation. ## Active lifecycle — no near-term end-of-life risk","metaTitle":"TM4C1237H6PZI7 Tiva C ARM Cortex-M4F MCU, 80MHz, 256KB Flash","metaDescription":"Texas Instruments TM4C1237H6PZI7 32-bit ARM Cortex-M4F MCU, 80MHz, 256KB Flash, 32KB SRAM, 2KB EEPROM, CAN/USB OTG, 100-LQFP, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Tiva™ C","Package":"Tube","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"2K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"69","Core Processor":"ARM® Cortex®-M4F","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 24x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"TM4C1237","Program Memory Size":"256KB (256K 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 ~ 3.63V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.5248","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a867ed917cc536d142ba3e11c70c6bde.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C1237H6PZI7/alternatives.json"},"ai":{"faq":[{"question":"Is TM4C1237H6PZI7 obsolete?","answer":"There is no indication of obsolescence or a last-time-buy window."},{"question":"What is the difference between TM4C1237H6PZI7 and TM4C1237H6PZIR?","answer":"The suffix 'R' typically denotes a different packaging or shipping option (e.g., Tape & Reel vs. Tube).
