SB LCD Keyswitches

The SB switches from [E³] are the industry-leading family of RGB-backlit, programmable LCD keys.

The SB6432 switch is a programmable LCD keyswitch with command-driven serial interfaces. The SB6432 integrates a graphical liquid crystal display with RGB backlighting in a keyswitch. The SB6432 keys are controlled via a serial interface to the integrated Advanced Technology™ electronics, which controls the interface, display and backlighting. The SB6432 self-initialises without external setup commands. Data only needs to be transmitted when a change is made to the display or background colors. Only six contact terminals are needed to provide power, clock and data lines as well as switch contacts. The contact pins of the internal switch are isolated from the internal electronics.

Features:

Resolution: 64 x 32 pixels

RGB Backlighting: over 10,000 RGB colors

Interface: SPI 2-wire serial (60kHz – 2Mhz)

No external clock required

Color Calibration: No color sorting due to Advanced Technology™ electronics. The RGB backlighting of all keyswitches is calibrated for maximum uniformity.

Initialisation: All keys self-initialise. No external setup commands required.

Power Consumption: Less than 60mA maximum current is needed when bright white backlighting is selected. Typical value is less than 25mA with one of the RGB colors.

New Extended Command Set

Write Display data with 8 data bits per transmitted data byte

Turn Display OFF, while maintaining bitmap

Turn Display ON; restoring last transferred bitmap

Additional color command including more than 100 brightness settings

Grouping of keys for simultaneous addressing and changing of color settings (flashing)
