概述

Description

TM4C123GH6PZI7 is TI’s Tiva C Series 32‑bit microcontroller built around an ARM Cortex‑M4F core, running up to 80 MHz. It pairs 256 KB of flash with about 32 KB of SRAM. Peripherals typically include USB 2.0 Full‑Speed, multiple serial interfaces (UARTs, SPI/SSI, I2C), GPIO, timers, PWM, a 12‑bit ADC, CRC, and a DMA controller. It supports low‑power modes and a watchdog, plus a built‑in bootloader for firmware updates. Development is supported by Code Composer Studio or Keil, with the TivaWare driver library and TI LaunchPad boards for quick prototyping. Applications span embedded control, data acquisition, USB devices, motor control, and general hobbyist projects. Debugging is via JTAG/SWD. Packaging varies (e.g., LQFP, other forms); check the datasheet or product page for exact pinout, memory map, and peripheral counts.
