Product details

80 MHz Cortex-M3 with integrated Ethernet and CAN

The Texas Instruments LM3S9L97-IBZ80-C5T is a 32-bit ARM Cortex-M3 MCU from the Stellaris series, running at 80 MHz with 128 KB of Flash and 48 KB of RAM. It integrates an Ethernet MAC, CANbus, USB OTG, and a 16-channel 10-bit ADC.

This part is marked Obsolete (EOL/Hot) by Texas Instruments. No official successor order code is listed. If you are still in design phase, consider evaluating a current-production Cortex-M3 or -M4 from TI's portfolio; we can help identify a pin-compatible or functionally equivalent alternative.

Connectivity set: Ethernet, CAN, USB OTG, and more

The 80 MHz core runs a lightweight TCP/IP stack alongside the control loop.

Core supply is 1.235 V to 1.365 V. Internal oscillator and brown-out detect reduce external component count.

Frequently asked questions

What is the replacement for LM3S9L97-IBZ80-C5T?
