1000 Series
1400's
Featuring 96K bytes of single cycle flash, 32K bytes of single cycle SRAM, and 50 MHz performance, Stellaris LM3S1400 series microcontrollers are perfect for cost-effective embedded control applications. The LM3S1400 series includes a battery-backed hibernation module featuring a real time clock (RTC) and 256 bytes of non-volatile state-save memory. Analog features in the LM3S1400 series include an analog comparator and up to 4 channels of 10-bit ADC at 500K samples per second. In addition, the series features 6 PWM outputs and a quadrature encoder input for sophisticated motion control.
