7 Segment LED
Overview
The CB-035 device is an, 8-digit 7-segment display.
Each segment can be individually addressed and updated separately using a 2 wire
interface. Only one external resistor (RSET) is required to set the current. LED brightness
can be controlled by analog or digital means.
The device include an integrated BCD code-B/HEX decoder, multiplex scan circuitry,
segment and display drivers, and a 64-bit memory. Internal memory stores the shift
register settings, eliminating the need for continuous device reprogramming.
