概述

Description

TM4C1231H6PMI7R is a Texas Instruments Tiva C Series microcontroller based on the ARM Cortex-M4F core. It targets embedded control and data-acquisition applications, typically running up to about 80 MHz with DSP/FPU support. On‑chip memory usually includes hundreds of kilobytes of flash and tens of kilobytes of SRAM (exact amounts depend on the package). Peripherals include GPIO, multiple serial interfaces (UART, I2C, SPI/SSI), timers and PWM, 12-bit ADCs, analog comparators, and USB on some variants. It provides ROM-based libraries (TivaWare) and a flexible interrupt system. Development is supported by TI Code Composer Studio and Keil, with Energia offering an Arduino-like option. Packaging comes in LQFP/QFN variants with pin counts matching the package. Use cases include hobbyist projects, education, and small embedded products requiring a reliable MCU with TI ecosystem.
