Product details

80 MHz Cortex-M3 with Ethernet and USB OTG

The Texas Instruments LM3S9U96-IQC80-A2T is a 32-bit ARM Cortex-M3 MCU from the Stellaris 9000 series, clocked at 80 MHz with a single-cycle multiply and hardware divide. It carries 384 KB of Flash and 96K x 8 of SRAM, enough for a modest TCP/IP stack and application code in a single-chip Ethernet node. The 100-LQFP package brings out 65 GPIOs alongside the full peripheral set: CAN, Ethernet MAC+PHY, USB OTG, multiple I²C/SPI/UART serial ports, and a 16-channel 12-bit ADC.

16-channel ADC and industrial I/O

The 16-channel 12-bit ADC is integrated. DMA-driven buffering offloads the CPU.

Frequently asked questions

What is the closest pin-compatible alternative to LM3S9U96-IQC80-A2T?

There is no direct pin-compatible replacement from TI's current portfolio. A board redesign to a Cortex-M4 or M7 series MCU would be required for an active-sourced BOM line.

What is LM3S9U96-IQC80-A2T's listed speed?

The core runs at 80 MHz. That clock rate, combined with the single-cycle multiply and hardware divide, gives enough headroom for a real-time control loop plus a lightweight Ethernet stack without external RAM.
