The Texas Instruments LM3S1162-EQC50-A2 is a Stellaris ARM Cortex-M3S 1000 series microcontroller built around a 32-bit single-core ARM Cortex-M3 processor running at 50 MHz.
The 46 I/O lines in a 100-LQFP package leave room for parallel displays or keypad matrices without a port expander.
A pin-compatible alternative within the Stellaris ARM Cortex-M3 family with the same 100-LQFP footprint and 2.5 V supply rail should be evaluated.
