概述

Description

TM4C1231D5PZI7R is TI’s TM4C/Tiva C Series 32‑bit microcontroller built around an ARM Cortex‑M4F core. Key points:
- Clock up to 80 MHz
- On‑chip memory: typically 256 KB flash and 32 KB RAM (plus small non-volatile storage in some variants)
- Peripherals: USB 2.0 Full‑Speed (device), multiple UART/SPI/I2C, GPIO, timers, PWM, 12‑bit ADC, analog comparators, watchdog
- Debug/Development: supported by TI’s TivaWare libraries and toolchains (Code Composer Studio, IAR)
- Applications: embedded control, data acquisition, sensing, motor control, and small IoT nodes
- Packaging/pins vary by option; consult the datasheet for exact counts
In short, it’s a high‑integration, Cortex‑M4F MCU designed for robust, cost‑effective embedded designs with a broad peripheral set.
