Product details

On the peripheral side you get CAN, I²C, SPI, SSI, UART, and a 12-channel 12-bit ADC — enough connectivity to tie into a CAN-based industrial network or a multi-sensor analog front-end without extra chips.

The FPU keeps sensor linearization from eating into interrupt latency.

256 KB Flash holds a typical FreeRTOS + TCP/IP stack + application image. The 32 KB RAM splits between stack, heap, and DMA buffers. The 2 KB EEPROM stores calibration coefficients and node ID without wearing the Flash.

The lifecycle status for this part is marked as EOL hot. We source this part through independent distribution and quote it to order against an RFQ.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C123BH6PMI7R?

The TM4C123GH6PMI7R is a pin-compatible alternative within the same Tiva C family, with the same 256 KB Flash, 32 KB RAM, and 64-LQFP package. Verify the exact order code against your BOM before substituting.

What is the speed rating of TM4C123BH6PMI7R?
