- TOKYO, Japan, February 28, 2018 -

Seiko Epson Corporation (TSE: 6724, "Epson") has begun shipping samples of a new memory display controller2. The new S1D13C00 controller is ideal for feature-rich digital watches and other wearable products that have a low-power memory display. Epson plans to produce 200,000 units per month when volume production begins in April 2018.

Epson is already volume-producing the S1C31D01, a microcontroller with an ARM® Cortex®-M0+ processor3 that supports memory displays. Epson believes that the S1C31D01 is the world's first4 microcontroller to have an embedded memory display controller. In contrast, the new S1D13C00 is a memory display controller that can be connected to a variety of different microcontrollers on the market. With three types of built-in host interfaces (indirect 8-bit parallel, QSPI, and SPI), the controller supports a wide variety of microcontrollers used by customers.

In addition to the embedded memory LCD controller for graphics, the S1D13C00 provides two programmable supply voltages for powering the different panels that are supported. This feature is important because it eliminates the need for external components and interface software development, allowing manufacturers to reduce product size and saving them time and effort. The new controller also has a 6-bit RGB parallel interface that accelerates video playback.

The controller also features a new event processor that renders video without going through a host CPU, so manufacturers can expect to extend the battery life of their products. The liquid crystal controller circuitry has been modified so that images can be rapidly written at speeds of up to 30 frames per second.

The controller chip also has an abundance of embedded peripheral circuits, among them a real-time clock/calendar (RTC), DMAC, QSPI, and sound generator.

Epson is committed to helping its customers improve the performance of their products with solutions that leverage Epson's efficient, compact, and precision technologies.

  1. *1 The footprints of the package and chip are the same size.
  2. *2 A liquid crystal display that has a memory function. On ordinary LCDs, even still images have to be refreshed. On memory LCDs, however, once an image is drawn on the display, it can be held there without being refreshed. This helps limit power consumption and saves battery life.
  3. *3 A processor designed by U.K-based ARM Limited, the ARM® Cortex®-M0+ is ARM's most energy-efficient processor and by far the most widely used processor in the market.
  4. *4 First among general-purpose microcontrollers (per Epson research conducted at the end of January 2018)
