Product details
Frequently asked questions
What is the closest pin-compatible alternative to TM4C1230C3PMIR?
The TM4C1231C3PM is the closest active pin-compatible sibling in the Tiva C family, adding USB OTG. For more Flash and SRAM, the TM4C123GH6PM (256 KB Flash, 32 KB SRAM, USB) is also pin-compatible but requires a firmware port.
What is TM4C1230C3PMIR's listed speed?
80 MHz on the ARM Cortex-M4F core — enough for real-time motor control and CAN communication without cycle-count pressure.
What series is TM4C1230C3PMIR?
Tiva C series from Texas Instruments — a family of ARM Cortex-M4F MCUs with integrated CAN, ADC, and multiple serial interfaces.
