That combination is unusual in a 144-pin LQFP — it means a single TM4C123GH6PGEI can act as a USB-to-CAN gateway, a motor-drive node talking CANopen, or a data-logger with USB mass-storage class. The Motion PWM peripheral is there for three-phase motor drive, and the quadrature encoder interface (QEI) reads position feedback directly. ## Temperature grade and supply — field-fit check The 144-LQFP (20×20 mm) is a hand-solderable package; no hot-air station needed for a field swap if you have a fine-tip iron and steady hands. ## Lifecycle: still in active production For dual-sourcing, the TM4C123GH6PMI is the same die in a 64-pin LQFP; the PGEI is the full 105-I/O version.","metaTitle":"Texas Instruments TM4C123GH6PGEI Tiva C MCU, 80MHz","metaDescription":"TM4C123GH6PGEI 32-bit ARM Cortex-M4F MCU at 80MHz with 256KB Flash, 32KB RAM, USB OTG, CANbus, 105 I/O, -40 to 85°C, 144-LQFP.","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, Motion PWM, POR, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, QEI, 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 24x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"TM4C123","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":"$16.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8040ef6c385e4a42724c396e9aa2bace.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C123GH6PGEI/alternatives.json"},"ai":{"faq":[{"question":"Does TM4C123GH6PGEI have USB OTG and CANbus?","answer":"Yes, it includes both USB OTG and CANbus controllers, plus I²C, SPI, SSI, UART, IrDA, and QEI — all on-chip."},{"question":"What are the differences between TM4C123GH6PGEI and TM4C123GH6PMI?","answer":"The PGEI comes in a 144-LQFP with 105 I/O and the full 24-channel ADC; the PMI is a 64-pin LQFP with fewer I/O and fewer ADC channels.
