Product details

80 MHz Cortex-M3 with Ethernet, USB OTG, and CAN on one die

The LM3S9B96-IQC80-B1: 65 GPIOs and a 16-channel 10-bit ADC in a 100-LQFP package.

Texas Instruments has marked the LM3S9B96-IQC80- as Obsolete. There is no factory last-time-buy window remaining, and no direct pin-compatible replacement announced from TI. Any new design should look at current-generation Cortex-M4 or M7 parts with equivalent Ethernet+USB+CAN — the Stellaris family was folded into the Tiva C Series, but the package and pinout differ.

The 100-LQFP (14x14 mm) is a standard fine-pitch package, hand-solderable with a decent hot-air station, and the 0.5 mm pitch means a two-layer PCB is feasible for simpler designs. Supply voltage is 1.235 V to 1.365 V core with separate 3.3 V I/O rail — plan for a dual-output regulator or a small LDO for the core.

Frequently asked questions

Is LM3S9B96-IQC80- obsolete?

Yes, Texas Instruments lists the LM3S9B96-IQC80- as Obsolete. No factory last-time-buy is active. Supply is limited to the surplus and broker channel.

What is the replacement for LM3S9B96-IQC80-?

TI has not announced a direct pin-compatible replacement. The Stellaris family evolved into the Tiva C Series (TM4C123/129), but those parts use different packages and pinouts. For a new design, evaluate a current Cortex-M4 or M7 MCU with Ethernet, USB OTG, and CAN peripherals — the TM4C1294NCPDT is a functional equivalent but requires a PCB layout change.

What are the specifications of LM3S9B96-IQC80-?

32-bit ARM Cortex-M3 at 80 MHz, 256 KB Flash, 96 KB RAM, 65 GPIO, 16-channel 10-bit ADC, Ethernet MAC+PHY, USB OTG, two CAN 2.0B, EBI/EMI, I²C, SPI, UART, SSI, QEI, PWM, and internal oscillator. Operating temperature -40 to 85 °C. Package 100-LQFP (14x14 mm). Supply 1.235 V to 1.365 V core.

What is LM3S9B96-IQC80-'s listed speed?

The core is rated for 80 MHz operation.
