SC16458
LED DRIVER IC (10 X 4 SEGMENTS)
DESCRIPTION
SC16458 is an LED controller driven on a 1/6 duty factor. It is
suitable for most application in a lot of consumer products and is
composed of one display memory, ten segment outputs, four grid
outputs and control circuit. The microcomputer often needs this chip
to build a highly reliable peripheral device. A three-line serial interface
is used by SC16458 to get serial data.
FEATURES
* CMOS technology
* Low power consumption
* 8-step dimming circuitry
* Serial interface for clock, data input, strobe pins
APPLICATIONS
* Microcomputer peripheral device
