It integrates 512KB Flash, 256KB SRAM, 6KB EEPROM, and a comprehensive set of communication peripherals including 10\/100 Ethernet MAC+PHY with IEEE 1588 PTP, USB 2.0 OTG, 2 CAN controllers, 8 UARTs, 4 SSI modules, and 10 I2C modules. The device features a hardware floating-point unit, 32-channel micro DMA, EPI for external memory\/peripheral interfacing, cryptographic acceleration, and a hibernation module with calendar mode. Internal ROM contains the TivaWare for C Series software library.","working_principle":"The TM4C1294KCPDTI3 is built around the ARM Cortex-M4F core with FPU executing single-precision floating-point operations in hardware, delivering 150 DMIPS at 120 MHz. The bus matrix connects the core to Flash, SRAM, and peripherals through multiple AHB and APB buses. The integrated Ethernet subsystem consists of a MAC layer connected to an internal PHY via MII, supporting 10\/100 Mbps with IEEE 1588 PTP hardware timestamps for precise time synchronization. The USB 2.0 OTG controller supports host, device, and OTG modes with optional ULPI interface for external high-speed PHYs. The 32-channel micro DMA controller offloads data transfers between memory and peripherals without CPU intervention. The EPI provides 8\/16\/32-bit parallel interface to external SRAM, SDRAM, or FPGA. Cryptographic acceleration supports AES, DES, SHA, and HMAC operations.","pin_description":"\n
