概要
Description
TM4C123GH6PZI7 is TI’s Tiva C Series microcontroller, based on the ARM Cortex-M4F core. It operates up to 80 MHz and typically provides 256 kB of flash and 32 kB of RAM. Peripherals include USB 2.0 Full‑Speed, a 12‑bit ADC, multiple PWM/timers, GPIO, and serial interfaces (UARTs, I2C, SPI/SSI). It also features a floating‑point unit, a nested vectored interrupt controller, a watchdog, and various power modes for low‑power operation. Packaging varies (available in multiple options), and the device is common on LaunchPad boards. Development is supported by TI’s TivaWare libraries and Code Composer Studio; other toolchains (Keil, IAR, GCC) can also be used. Typical uses: embedded control, sensing, data acquisition, and USB peripherals. For exact specifications (memory counts, peripherals, and packaging) refer to the official TM4C123GH6PZI7 datasheet and Technical Reference Manual.
Equivalent
Equivalents are other packaging variants of the same TM4C123GH6x MCU from TI. The core silicon is identical to devices like TM4C123GH6PM (common LQFP-64) and other package/lot variants such as TM4C123GH6PZ. The TM4C123GH6PZI7 itself is the same MCU in a different package/lot; there aren’t different silicon equivalents with the same features.
