Product details

80 MHz Cortex-M4F with FPU — real-time headroom for mixed-signal control

Memory map and peripheral mix — what fits, what does not

64 KB of program Flash with 2 KB of dedicated EEPROM. The EEPROM is useful for calibration constants and fault logs that survive a firmware update — no separate serial EEPROM needed on the board. The 24 KB SRAM is tight for large frame buffers; if your application uses the USB OTG with isochronous transfers, budget the RAM carefully.

Industrial temperature and supply range — board-level fit

Supply range is 1.08 V to 3.63 V.

Frequently asked questions

What is the closest pin-compatible alternative to TM4C1237D5PZI7R in this family?

Within the Tiva C TM4C123x family, the TM4C123GH6PMI7R is a common pin-compatible upgrade with 256 KB Flash and 32 KB RAM in the same 100-LQFP package. Verify the peripheral set differences — the GH6 adds more USB endpoints and a second CAN controller — before swapping into an existing BOM.

What compliance documentation does TI provide for TM4C1237D5PZI7R?

Texas Instruments provides RoHS and REACH compliance declarations for this part. The 100-LQFP package is lead-free (green) per TI's standard material declaration. No separate UL or IEC certification is listed for this component; system-level certification depends on the end application.
