The LCD reference design is developed using the Kinetis KL28Z through the standalone peripheral module FlexIO. The polling method is used to copy data from SRAM or flash to FlexIO’s shifter buffer. Image Kinetis board is powered by an ARM® Cortex-M0, providing up to 96 MHz CPU performance besides supporting ultra-low power. KL28Z’s FlexIO emulates 8080 interface, and drives a 320×240 TFT LCD module. DAM or displaying applications, such as HMI, can be built based on this demo. The refresh rate is up to 128 fps with 16-bit width data bus and 48MHz core clock.
