Product details

80 MHz Cortex-M4F with FPU — what it buys you on the bench

The TM4C123FH6PMI7R is a Texas Instruments Tiva C Series 32-bit ARM Cortex-M4F microcontroller running at 80 MHz. Program memory is 256 KB Flash, backed by 32K x 8 RAM and 2K x 8 EEPROM.

Industrial temperature range — where it lives in the panel

Supply range is 1.08 V to 3.63 V.

Lifecycle reality — EOL hot means move now

The lifecycle stage on this part is marked EOL hot. That means the last-time-buy window is active and closing — TI has issued the end-of-life notice, and the final order date is approaching. If this MCU is on your BOM, the procurement action is to secure lifetime buy quantities or identify a migration path now.

Frequently asked questions
