Four digit seven segment LED displays combined with an 8 digit, multiplexed drive, integrated circuit with a cascadable serial interface. The cascadable feature allows units to be daisy chained and run from the same 3 wire bus. Four digits are mounted with the driver on to the PCB which also has connections for the BM multiplexed display family allowing expansion to 8 digits. The serial interface is compatible with SPI, QSPI and MICROWIRE. The board has jumpers that allow selection of the cascade direction. An on chip decoder allows code B or undecoded modes and supports 16 level digital dimming, low power shutdown and test modes. A single +5 volt supply is required. Each display has a right hand decimal point. LED sizes include 14mm (0.56inch), 20mm (0.8inch) 25mm (1inch) and 38mm (1.5inch) display areas. The BIFC may be used to control this display.
