Product details

The TM4C123AE6PMI7R is a 32-bit ARM Cortex-M4F MCU from the Tiva C series, clocked at 80 MHz with a single-precision floating-point unit. That FPU is the differentiator here: for motor-control FOC, sensor fusion, or audio filtering, the hardware divide and MAC instructions cut cycle count versus a software-emulated M3. The 128 KB Flash and 32 KB SRAM are sized for mid-complexity firmware — a CANopen stack plus a PID loop fits without external memory. 49 GPIOs in a 64-LQFP package give enough headroom for a mixed I/O board with a parallel LCD or encoder interface.

Peripheral list covers CAN, I²C, SPI, UART, QEI, and motion PWM.

Lifecycle: EOL — plan the last-time buy

This part is flagged end-of-life (EOL). We source and quote it to order against an RFQ.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C123AE6PMI7R?

The TM4C123 family shares the same 64-LQFP footprint and peripheral set across density options. A sibling like the TM4C123GH6PMI7 (256 KB Flash, 32 KB SRAM) is pin-compatible — check that your firmware fits the larger Flash before substituting.

What is the core speed of TM4C123AE6PMI7R?

The ARM Cortex-M4F core runs at 80 MHz, with a hardware FPU for single-precision math.

Where can I buy TM4C123AE6PMI7R?
