That FPU is the difference between a 32-bit software-emulated divide taking dozens of cycles and a hardware divide in one cycle — relevant for control loops in motor drives, power inverters, and sensor fusion where the math budget is tight. The 80 MHz clock also keeps the flash wait-state penalty manageable: at that speed the prefetch buffer hides most of the latency for sequential code. ## 64 KB Flash and 24 KB SRAM — sizing the firmware envelope 64 KB of program Flash and 24K x 8 of SRAM define the firmware footprint. For a typical industrial CAN node running a real-time OS, a USB stack, and a control loop, 64 KB is workable but leaves little headroom for over-the-air update staging or extensive lookup tables. The 2K x 8 EEPROM emulation block handles calibration and configuration storage without wearing the Flash. If the firmware grows beyond 64 KB, the pin-compatible TM4C123GH6PM (256 KB Flash) is the natural step up within the same 64-LQFP footprint. ## Peripheral mix — CAN, USB, and serial for industrial connectivity The Tiva C series has broad distribution support, so multi-sourcing through independent channels is straightforward.","metaTitle":"TM4C1233D5PMIR Tiva C MCU, ARM Cortex-M4F 80 MHz","metaDescription":"TM4C1233D5PMIR Texas Instruments Tiva C series 32-bit ARM Cortex-M4F MCU. 80 MHz, 64 KB Flash, 24K x 8 RAM, 2K x 8 EEPROM, CAN/USB, -40 to 85°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":"Tape & Reel (TR)","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, USB","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":"TM4C1233","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.63V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.7813","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/83f9e97a8ff83befa9da0bf21a034ad0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C1233D5PMIR/alternatives.json"},"ai":{"faq":[{"question":"What is the flash memory size of TM4C1233D5PMIR?","answer":"The program memory is 64 KB (64K x 8) of Flash.
