Dot matrix with built-in control

24 October 2001 Opto-Electronics

Kingbright offers a dot matrix display that has a built-in control IC. The on-board CMOS has a 10 x 14 bit RAM, one bit associated with one LED, each to generate user-defined characters. The product is designed to work with the serial port of most common microprocessors. Data is transferred into the display through serial data input [data], clocked by the serial data clock [sdclk], and enabled by the load input [load].

LED drivers, decoders, muxes, and oscillator are built in. Eight dimming levels are possible (internal software brightness control: 0, 66, 13, 20, 27, 40, 53, 100%). Hardware/software clear functions and lamp test.
