Electronic Paper Display, E-Paper, E-Ink, EPD. EFM32 Cortex-M3. PDI

Electronic paper is the lowest power display technology because the devices do not consume energy after they have been updated, however long the image is displayed.

The ARM Cortex-M3 EFM32 Gecko MCU is used to control the low power e-paper (EPD) displays from PDI.

PDI's e-paper displays are ruggedly designed for industrial and commercial applications, reflect light like ordinary paper, making them easy to read in both outdoor and indoor applications. They are currently available in sizes from 1.44-inch to 10.2-inch (37mm to 260mm), the largest with a resolution of 1280 x 1024 (160dpi).

Energy Micro's EFM32G890F128 Gecko MCU combines ultra-low power and high processing capabilities based on the powerful 32-bit ARM Cortex-M3 processor.

Efficient energy modes, a low energy UART and the device's Peripheral Reflex System make the EFM32 the ideal controller for e-paper applications. The Gecko MCU delivers the processing power needed to refresh the EPD display very quickly. The "EPD-On SK2" reference design uses the standard EFM32 Gecko starter kit (STK) to handle waveform library functions, image transmission via a USB and UART bridge, driving the electrophoretic display's chip-on-film controller, and displaying the optimized result. The complete reference design from Retronix is powered by USB or a CR2032 coin cell battery.
