Product details

The TM4C1230C3PMI7R: 32-bit ARM Cortex-M4F MCU from TI's Tiva C series, clocked at 80 MHz with a single-precision FPU. 32 KB Flash and 12 KB RAM define the value-line envelope.

The 49 I/O lines are mapped through a 64-LQFP package — a 10x10 mm footprint that fits on compact 2-layer boards. CAN is the key for industrial bus nodes; the rest covers sensor and display links. Internal oscillator means no external crystal for basic timing, though a precision clock still helps for CAN bit-timing margin.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C1230C3PMI7R?

The TM4C123GH6PM series (same 64-LQFP package, same 80 MHz Cortex-M4F core) offers more Flash and RAM while maintaining pin compatibility. It is a direct upgrade path for designs needing additional code space or data buffering.

What is TM4C1230C3PMI7R's listed speed?

The core runs at 80 MHz, which is the maximum clock for this Tiva C value-line MCU. That speed is sufficient for real-time control loops and CAN message handling at 1 Mbps.
