Microcontrollers Procurement Notes

Verify the suffix 'R' indicates reel packaging when ordering. Confirm the specific speed grade and temperature range match the application requirements. Ensure the LQFP-64 footprint aligns with the PCB design. Check for RoHS compliance status in the latest datasheet before finalizing procurement specifications.

Microcontrollers Selection Notes

Select this component when a balance of processing power and peripheral count is needed in a compact package. The 64 kB flash and 24 kB RAM suit moderate complexity firmware. The inclusion of CAN interface makes it suitable for automotive or industrial networks where other variants may lack this specific controller.

Microcontrollers Part Context

This part belongs to the TM4C123 family of high-performance 32-bit MCUs based on the ARM Cortex-M4F core. It shares architectural similarities with other Tiva C Series devices but differs in memory size and pin count. The AH6 variant specifically denotes the 64 kB flash configuration within the 64-pin form factor.

Microcontrollers Replacement Considerations

TM4C123AH6PMI is the tape-and-reel equivalent without the trailing R suffix. TM4C123BH6PMI offers similar features but may differ in specific pinout assignments or peripheral availability. Verify electrical characteristics and software compatibility before substituting.
