Epson Shipping Samples of New 16-bit MCU for Driving LEDs at Up to 56 mA

Ideal for control panels with displays for factory automation systems and home applications

- TOKYO, Japan, July 20, 2016 -
Seiko Epson Corporation (TSE: 6724, "Epson") has begun shipping samples of the
S1C17M13, a new 16-bit microcontrol unit (MCU) with Flash memory integrated onchip.
This MCU is designed to drive light-emitting diodes (LEDs) at up to 56 mA*.
Epson plans to produce 200,000 units per month when volume production beings in
March 2017.

Epson has long integrated drivers in its MCUs to control LCDs in applications that
use them. Recently, however, there has also been a sharp increase in the number of
factory automation products and home appliances that use 7-segment LED displays
or LED indicators. Epson anticipates ongoing demand for LEDs as a means for
displaying simple information, as LEDs are bright, self-emitting, and easily visible
even in dark environments.

On the other hand, LEDs have to be driven at a current of about 10 mA to produce a
constant level of brightness. This has made it necessary to add dedicated external
driving circuits to today's low-voltage, low-power MCUs. Moreover, users have had to
develop their own control software and embed it in an MCU to achieve efficient
multiple-digit segment displays. LEDs are simple, but they require more external
driving components than LCDs. Users have thus had to spend considerable time
and money developing LED software-as much if not more than for LCDs. Reducing
users' costs and development times has thus been an issue.

The S1C17M13, Epson's first MCU for LED display applications, is ideally
engineered to solve this issue. This product operates at voltages ranging from 1.8 V
to 5.5 V and readily supports the 5 V needed for most factory automation products.
The new MCU has five pins that can output up to 56 mA*. By using these high-output
pins as common pins in combination with an additional eight other segment pins,
users can drive a segment LED display with up to 8 segments x 5 common pins
without the use of external transistors on the common lines.

In addition, the MCU has an integrated hardware controller that supports dynamic
lighting control. Customers can use a simple software setting to select any segment
(LED) they wish to light up. They can fine-tune the lighting interval and adjust the
brightness to any of four levels. These new features will help users reduce the cost of
their products as well as their total development times.

Epson also plans to commercialize a derivative product in the series (the
S1C17M12) that does not include the 12-bit AD converter. Two types of evaluation
boards are also available for the new product.

* Maximum output current per pin at an operating voltage of 5 V. Not capable of
multiple simultaneous outputs.
