Program memory is 64 KB of Flash, paired with 24 KB of SRAM and a separate 2 KB EEPROM block for calibration constants or boot parameters that survive reprogramming. ## Package and supply — board-level fit Housed in a 64-LQFP with a 10x10 mm body and 0.5 mm pitch, it reflows on a standard lead-free profile. The internal oscillator starts up without a crystal — useful for cost-sensitive boards where the CAN or USB clock accuracy isn't critical. The base product number TM4C1231 covers a density family, so if a future BOM needs more Flash the TM4C1233 variants are the natural step-up.","metaTitle":"Texas Instruments TM4C1231D5PMT Tiva C MCU","metaDescription":"TM4C1231D5PMT 32-bit ARM Cortex-M4F MCU, 80MHz, 64KB Flash, 24KB SRAM, 2KB EEPROM, -40°C to 105°C, 64-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":"24K 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","Mounting Type":"Surface Mount","Number of I/O":"43","Core Processor":"ARM® Cortex®-M4F","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 12x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"TM4C1231","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.63V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.8644","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/86a4b223dde2091ea8eab792cf4d86b2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C1231D5PMT/alternatives.json"},"ai":{"faq":[{"question":"Does the TM4C1231D5PMT have USB connectivity?","answer":"No. The connectivity block includes CAN, I²C, IrDA, Microwire, SPI, SSI, and UART/USART, but there is no USB peripheral on this die.
