The LM3S3748-IQC50-A0T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris® 3000 series, built around a 50 MHz single-core processor with 128 KB of Flash program memory and 64K x 8 of SRAM. The industrial temperature range (-40 to 85 °C) suits factory-floor and outdoor telecom enclosures.
The 50 MHz Cortex-M3 core and 64K x 8 SRAM support real-time control loops and moderate protocol stacks.
The Stellaris LM3S3xxx family members in the same 100-LQFP package are pin-compatible across the series, so a board respin may be avoided. Check the specific Flash and RAM options within the family for a drop-in replacement.
The core runs at 50 MHz.
