Built around the ARM Cortex-M4F core with hardware floating-point unit, it delivers 150 DMIPS at 120 MHz. The device stands out with its integrated 10\/100 Ethernet MAC and PHY, supporting IEEE 1588 Precision Time Protocol for time-synchronized network applications. With 512KB Flash, 256KB SRAM, and 6KB EEPROM, it provides ample memory for complex networked applications. The extensive peripheral set includes USB 2.0 OTG, dual CAN, and 8 UART ports for multi-protocol communication.","working_principle":"The TM4C1294KCPDTI3 is powered by an ARM Cortex-M4F processor with a hardware floating-point unit (FPU) that accelerates single-precision floating-point math operations critical for DSP and control algorithms. The integrated Ethernet MAC+PHY provides a complete physical layer interface, eliminating the need for an external Ethernet PHY chip. The 32-channel \u00b5DMA controller offloads data transfer tasks from the CPU, enabling concurrent peripheral operations. The External Peripheral Interface (EPI) supports connections to external memory and peripherals with configurable data widths (8\/16\/32-bit). The Hibernate module maintains RTC operation and backup register data in ultra-low-power mode, enabling time-stamped event logging in power-conscious applications.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>VDD<\/td><td>Power Supply (3.3V)<\/td><\/tr><tr><td>2<\/td><td>PA0\/U0Rx<\/td><td>GPIO Port A0 \/ UART0 Receive<\/td><\/tr><tr><td>3<\/td><td>PA1\/U0Tx<\/td><td>GPIO Port A1 \/ UART0 Transmit<\/td><\/tr><tr><td>4<\/td><td>PA2\/SSI0Clk<\/td><td>GPIO Port A2 \/ SSI0 Clock<\/td><\/tr><tr><td>5<\/td><td>PA3\/SPI0Fss<\/td><td>GPIO Port A3 \/ SSI0 Frame<\/td><\/tr><tr><td>6<\/td><td>PA4\/SPI0Rx<\/td><td>GPIO Port A4 \/ SSI0 Receive<\/td><\/tr><tr><td>7<\/td><td>PA5\/SPI0Tx<\/td><td>GPIO Port A5 \/ SSI0 Transmit<\/td><\/tr><tr><td>64<\/td><td>PH0\/EP0S0<\/td><td>GPIO Port H0 \/ EPI Signal<\/td><\/tr><tr><td>65<\/td><td>PH1\/EP0S1<\/td><td>GPIO Port H1 \/ EPI Signal<\/td><\/tr><\/table>","application_scenarios":"The TM4C1294KCPDTI3 excels in networked industrial applications requiring integrated Ethernet connectivity. In smart grid systems, the IEEE 1588 PTP support enables precise time synchronization across distributed nodes. The dual CAN interfaces make it suitable for automotive gateway controllers bridging CAN and Ethernet networks. For building automation, the combination of Ethernet, multiple UARTs, and GPIO enables centralized control of HVAC, lighting, and security systems. The USB OTG capability allows the device to function as both a USB host for peripheral connectivity and a USB device for programming and data transfer.","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>TM4C1290NCPDTI3<\/td><td>Texas Instruments<\/td><td>No Ethernet PHY variant<\/td><\/tr><tr><td>TM4C1294KCPDTI3R<\/td><td>Texas Instruments<\/td><td>Tape & Reel packaging<\/td><\/tr><tr><td>TM4C129ENCPDTI3<\/td><td>Texas Instruments<\/td><td>Enhanced version with more memory<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6476","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=6476"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6476\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6476"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6476"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6476"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6476"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
