The ARM Cortex-M4F core includes a single-precision floating-point unit that executes multiply-accumulate in one cycle. For a PID loop running at 10 kHz, the FPU handles the coefficient math in firmware rather than requiring an external DSP or a lookup table. The 80 MHz clock gives about 12.5 ns per instruction cycle — enough headroom for a 20 kHz current loop with a few hundred lines of C code before you hit the timing wall. The internal oscillator means it boots without a crystal — useful for a quick prototype or a cost-sensitive run where ±1% accuracy is acceptable. ## Memory sizing for a typical BOM 256 KB of Flash fits a FreeRTOS kernel, a CANopen or Modbus stack, and about 80 KB of application code before you start compressing. The 32 KB SRAM holds a couple of 1 KB CAN message buffers, a 4 KB TCP stack, and still leaves room for a 16 KB data acquisition ring buffer. The 2 KB EEPROM is handy for calibration constants and serial numbers — no external 24LCxx needed. The base product number TM4C123 covers a range of Flash and pin-count options, so if a future design needs more memory or I/O, a pin-compatible migration within the family is possible without a board spin.","metaTitle":"Texas Instruments TM4C123BH6PZIR ARM Cortex-M4F MCU, 80 MHz","metaDescription":"Texas Instruments TM4C123BH6PZIR Tiva C Series MCU: 32-bit ARM Cortex-M4F at 80 MHz, 256 KB Flash, 32 KB SRAM, 2 KB EEPROM, 22x12b ADC, CAN/I²C/SPI/UART, -40","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":"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","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 22x12b","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":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.63V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9741","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e87050f2b106e42b7e34a0966f4c68dd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TM4C123BH6PZIR/alternatives.json"},"ai":{"faq":[{"question":"What is the TM4C123BH6PZIR's core speed and memory?","answer":"It runs an ARM Cortex-M4F core at 80 MHz with a hardware FPU."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TM4C123BH6PZIR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TM4C123BH6PZIR when reusing this data.
