Product details

What this Stellaris MCU brings to an industrial design

The Texas Instruments LM3S9B95-IBZ80-C1 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 9000 series, clocked at 80 MHz. It integrates 256 KB of Flash and 96 KB of SRAM.

80 MHz Cortex-M3 — what it means for protocol throughput

At 80 MHz the Cortex-M3 core can sustain a full-duplex Ethernet MAC while servicing a CAN bus and a USB OTG bulk transfer. The 96 KB SRAM provides buffer space for Ethernet packets and a CAN message queue.

Obsolete — last-time-buy already passed

The LM3S9B95-IBZ80-C1 is officially obsolete. There is no active replacement listed by Texas Instruments within the Stellaris family; the entire Stellaris line has been superseded by the Tiva C series, which uses a different pinout and requires a board redesign.

Connectivity and peripheral integration

The part carries Ethernet MAC, two CAN controllers, USB OTG, and multiple UART/SPI/I²C serial ports. The 65 GPIOs are multiplexed with these peripherals.

Frequently asked questions

Is LM3S9B95-IBZ80-C1 obsolete?

Yes, the LM3S9B95-IBZ80-C1 is officially obsolete. No further production runs are planned. Stock is limited to surplus inventory from the original manufacturing cycle.

What is the replacement for LM3S9B95-IBZ80-C1?

Texas Instruments does not list a direct pin-compatible replacement. The Tiva C series (TM4C123/129) offers similar peripherals but uses a different pinout and package, requiring a PCB redesign. For an exact form-fit-function substitute, the only option is sourcing the original order code through independent distribution.

Does LM3S9B95-IBZ80-C1 have Ethernet MAC?

Yes, the LM3S9B95-IBZ80-C1 includes an integrated Ethernet MAC controller with an external PHY interface.
