Product details

The LM3S9D96-IQC80-A2: Packaged in a 100-LQFP (14x14 mm body), surface-mount, with 65 general-purpose I/O lines and a 16-channel 12-bit ADC.

Connectivity and peripheral set

This part integrates Ethernet MAC+PHY, USB OTG, CAN, and multiple serial interfaces (UART, I²C, SPI, SSI, IrDA, LIN, Microwire) — it can serve as a central node in a mixed-protocol industrial control network. On-chip peripherals include a quadrature encoder interface (QEI) for motor position feedback, PWM outputs, DMA, and a brown-out detect with POR — reducing external glue logic in a motor-drive or motion-control design.

Lifecycle reality — officially obsolete

For a BOM line that requires this exact order code, sourcing runs through independent distribution and surplus channels. Availability is lot-specific; quantities and date codes are confirmed at RFQ time.

Frequently asked questions

What is the closest pin-compatible alternative to the LM3S9D96-IQC80-A2?

No direct pin-compatible replacement is listed by Texas Instruments for this specific order code within the Stellaris family. A board-level redesign with a different MCU family would be required for new production.
