For a design that needs to talk to a CAN bus on one side and a USB host on the other — say an industrial gateway or a vehicle telematics node — this single chip covers both without an external USB-to-CAN bridge. The 105 I/O pins in the 144-LQFP package leave plenty of GPIO for local sensors, buttons, and indicators. The 22-channel 12-bit ADC can sample analog inputs across that temperature range with the internal oscillator — no external reference needed for moderate accuracy. For dual-sourcing resilience, the Tiva C family includes several 144-pin parts with the same footprint — the TM4C123GH6PM is a common cross-shop candidate with additional Ethernet MAC+PHY, though the pinout differs in the Ethernet signal group.","metaTitle":"TM4C1237H6PGEI Tiva C ARM Cortex-M4F MCU, 80 MHz","metaDescription":"Texas Instruments TM4C1237H6PGEI 32-bit ARM Cortex-M4F MCU at 80 MHz with 256 KB Flash, 32 KB RAM, 2 KB EEPROM, USB OTG, CAN, 105 I/O.","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":"Tray","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":"105","Core Processor":"ARM® Cortex®-M4F","Package / Case":"144-LQFP","Product Status":"Active","Data Converters":"A/D 22x12b","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":"144-LQFP (20x20)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.63V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.9438","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cf22c1aa58220ec5e8fd6cfe19173ceb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C1237H6PGEI/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TM4C1237H6PGEI and TM4C123GH6PM?","answer":"The TM4C123GH6PM adds an integrated 10/100 Ethernet MAC+PHY that the TM4C1237H6PGEI lacks.
