Product details

The TM4C123GE6PMI7R is a Texas Instruments Tiva C series 32-bit ARM Cortex-M4F MCU clocked at 80 MHz. The 43 GPIOs are in a 64-LQFP package.

Connectivity mix: CAN and USB OTG on the same die

This part carries CAN, USB OTG, three UART/USART blocks, SPI, I2C, and SSI. The CAN controller and USB OTG can run simultaneously.

This means the manufacturer may have issued a last-time-buy notice or is winding down production. The base product number TM4C123 covers a range of Flash and RAM options; a pin-compatible upgrade path exists within the Tiva C series if the original code becomes unavailable.

Industrial temperature grade — deployment envelope

Brown-out detect and POR peripherals handle supply-rail glitches.

Frequently asked questions

Is TM4C123GE6PMI7R still active or going end-of-life?

The official product status shows Active, but the sourcing record flags an end-of-life hot indicator. Confirm current lifecycle status at quote time before committing the BOM line.

What is a direct replacement for TM4C123GE6PMI7R?

A pin-compatible upgrade within the Tiva C series is the TM4C123GH6PM, which offers 256 KB Flash and 32 KB RAM in the same 64-LQFP package. Verify firmware and peripheral compatibility before substituting.

Does TM4C123GE6PMI7R support CAN bus and USB OTG simultaneously?

Yes, the CAN controller and USB OTG can run concurrently. The DMA engine and shared RAM handle buffer arbitration without software bit-banging.

Where can I buy TM4C123GE6PMI7R with stock in the USA?

We source this part to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock figure on this page is a firm offer.

What is TM4C123GE6PMI7R's listed speed?

The core runs at 80 MHz, with a single-precision floating-point unit that accelerates math-heavy control loops without a separate DSP.
