Runs at 80 MHz with 512 KB Flash and 96K x 8 SRAM.
80 MHz Cortex-M3 core with 512 KB Flash and 96 KB RAM supports a TCP/IP stack alongside a CANopen or Modbus application.
Texas Instruments has marked the LM3S9D90-IBZ80-A2 as obsolete. No official successor order code is listed.
There is no pin-compatible direct replacement from TI. The Stellaris line was replaced by the Tiva C Series (TM4C129x) and MSP432E4 families, which require a board redesign due to different pinouts and peripheral maps.
This obsolete part is sourced through independent distribution. Submit an RFQ for current pricing and availability — stock is confirmed at quote time.
Yes, the connectivity block includes a USB OTG controller, supporting host, device, and OTG modes.
The core runs at 80 MHz, which is the maximum clock frequency for this device.
