The LM3S6C65-IBZ80-A2: The LM3S6C65 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 6000 series, running at 80 MHz with 512 KB of Flash program memory and 64 KB of SRAM.
The 80 MHz ARM Cortex-M3 core runs a lightweight RTOS alongside an Ethernet protocol stack without an external co-processor.
There is no direct pin-compatible drop-in from TI's current portfolio. The TM4C123 and TM4C129 series offer similar Cortex-M4 cores with Ethernet but require a PCB layout change due to different BGA ball assignments. For an existing design, we recommend procuring the exact LM3S6C65-IBZ80-A2 through our RFQ process while inventory lasts.
The core runs at 80 MHz, based on the ARM Cortex-M3 processor.
This obsolete part is sourced to order against an RFQ through our independent distribution network. Submit a request for current availability and pricing — we confirm both at quote time.
