TM4C1231D5PZI7R

The TM4C1231D5PZI7R is TI’s Tiva C Series microcontroller built around a 32‑bit ARM Cortex‑M4F core. It runs up to 80 MHz and includes a hardware FPU and DSP instructions. On‑chip memory typically includes 256 KB of flash and about 32 KB of SRAM for code and data. Peripherals cover a broad embedded feature set: GPIO, multiple timers and PWM, 12‑bit ADC, UART/USART, SPI (SSI), I2C, and USB 2.0 full‑speed device support, plus CRC, watchdog, and various low‑power modes. It’s supported by TI’s TivaWare libraries and development tools (Code Composer Studio, IAR, Keil), with TI LaunchPad kits and numerous reference designs for USB devices, data acquisition, motor control, and education. For exact pinout, memory configuration, and electrical specs, consult the TM4C1231D5PZ/TM4C1231D5PZI7R datasheet and product page.
