The Texas Instruments LM3S801-EGZ50-C2 is a 32-bit ARM Cortex-M3 MCU from the Stellaris® ARM® Cortex®-M3S 800 series, clocked at 50 MHz with 64 KB of Flash program memory and 8 KB of SRAM. It packs 36 general-purpose I/O lines, a full set of serial interfaces (I²C, Microwire, QEI, SPI, SSI, UART/USART), and on-chip brown-out detect, POR, PWM, and watchdog timer peripherals. This is a mid-range industrial microcontroller meant for motor control, sensor fusion, human-machine interface front ends, and distributed I/O nodes where deterministic interrupt response and a -40 to 105 °C operating range are required.

Frequently asked questions
Who supplies LM3S801-EGZ50-C2 and how is it quoted?
This part is sourced through independent distribution channels and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and delivery commitment.
What is the closest pin-compatible alternative to LM3S801-EGZ50-C2?
Within the Stellaris family, higher-density siblings (e.g., LM3S811 with more Flash/RAM) share the same 48-VQFN footprint and peripheral set, but verify the exact pinout and register map against your firmware before committing. There is no direct, fully pin-compatible Tiva-C replacement — TI's migration guides require a board spin.
What is LM3S801-EGZ50-C2's listed speed?
The core runs at 50 MHz, which is the maximum clock from the internal oscillator or an external source.
