Product details

80 MHz Cortex-M3 with Ethernet and USB OTG

The LM3S9B92-IBZ80-C3 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 9000 series, clocked at 80 MHz with a single core.

256 KB Flash and 96 KB SRAM — sizing the firmware and data buffers

The 256 KB Flash is the program memory; the 96 KB SRAM is split between stack, heap, and DMA buffers.

Texas Instruments has marked the LM3S9B92-IBZ80-C3 as obsolete.

Connectivity and I/O — what the peripheral set delivers

The 65 GPIOs are multiplexed with the peripheral functions. The Ethernet MAC requires an external PHY; the USB OTG needs an external transceiver.

Frequently asked questions

What is LM3S9B92-IBZ80-C3's listed speed?
