Product details

The part is rated for industrial temperature range (-40°C to 85°C) and runs on a supply from 1.08 V to 3.63 V. Typical applications include industrial control, motor drives, sensor hubs, and CAN-bus gateway nodes where the Cortex-M4F DSP extensions and the integrated 12-bit ADC array (12 channels) handle mixed-signal workloads without an external converter.

80 MHz Cortex-M4F — what it buys you

The 80 MHz core with single-cycle MAC and hardware divide handles PID loops, Modbus RTU, and CANopen nodes. The FPU processes sensor fusion math in firmware.

Memory budget — 64 KB Flash, 24 KB SRAM, 2 KB EEPROM

64 KB of Flash supports a bootloader and a moderate application. The 24 KB SRAM leaves room for buffers and stack. The 2 KB EEPROM stores calibration constants.

Frequently asked questions

What is the speed of TM4C1231D5PMI7R?

The core runs at 80 MHz. That is the maximum clock for the ARM Cortex-M4F on this device.

What is the closest pin-compatible alternative to TM4C1231D5PMI7R?

No official pin-compatible successor is listed in the lifecycle record. The Tiva C family includes higher-density Flash variants (e.g., 128 KB or 256 KB) in the same 64-LQFP package, but pin compatibility should be verified against the respective datasheets before substitution.
