BL55076 Overview
The BL55076 is a peripheral device, which interfaces to almost any Liquid Crystal Display (LCD) having low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four back planes and up to 40 segments and can easily be cascaded for larger LCD applications. The BL55076 is patible with most microprocessors/micro controllers and municates via a two-line bi-directional IIC...
