Product details

The 50 MHz core delivers roughly 1.25 DMIPS/MHz, enough to handle a UART-to-SPI bridge, a PWM motor-control loop, and a 10-bit ADC scan without stalling the main loop. Program memory is 64 KB of Flash (64K x 8), which fits a moderate firmware image with a bootloader and one or two application layers; the 8K x 8 SRAM provides workspace for stack and small data buffers.

Peripherals and connectivity — what is on the bus

The 32 general-purpose I/O lines are multiplexed with these peripherals; check the alternate-function map in the datasheet before committing the pinout. The 4-channel 10-bit ADC samples at a rate adequate for current-sense or temperature monitoring, but not for high-speed audio or vibration analysis.

No stock or lead-time figures are published here, but the RFQ process returns a firm commitment.

Frequently asked questions

Does the LM3S811-EGZ50-C2 have Flash memory?

Yes — it has 64 KB of on-chip Flash program memory (64K x 8), plus 8K x 8 SRAM for data.

Can the LM3S811-EGZ50-C2 replace the LM3S811-EGZ50-C1?

The LM3S811-EGZ50-C2 is a later revision in the same base product family (LM3S811). Pin compatibility and functional equivalence should be verified against the datasheet revision history, but the -C2 suffix typically indicates a stepping or minor process change — not a footprint change.
