Product details

The TM4C1237D5PMI is a Texas Instruments Tiva™ C series 32-bit ARM Cortex-M4F microcontroller with a single-precision floating-point unit running at 80 MHz. That FPU shaves cycles off sensor-fusion math and PID loops compared to a software-emulated float library. The 64 KB of Flash (64K x 8) and 24 KB of SRAM (24K x 8) are sized for a single control or protocol-stack task — think a CANopen node with a USB service port, or a motor drive running field-oriented control on one axis. The 2 KB EEPROM (2K x 8) holds calibration coefficients and configuration parameters without an external serial EEPROM, which saves a board position and a programming step on the line.

Connectivity and I/O — USB OTG, CAN, and serial buses

That means it can act as a USB-to-CAN gateway, a human-machine interface with a touch panel, or a data concentrator talking to multiple sensor buses.

Frequently asked questions

Will TM4C1237D5PMI drop into a panel that was specified around F280041PZQR without rewiring?

No — the F280041PZQR is a C2000 C28x core (100 MHz) in a different package and pinout, with a different peripheral set and a 125°C temperature grade. The TM4C1237D5PMI is not pin-compatible and would require a board redesign. They are not drop-in replacements.
