AS1107WL集成電路（IC）的顯示驅(qū)動器規(guī)格書PDF中文資料

General Description

The AS1106 and the AS1107 are compact display drivers for 7-segment numeric displays of up to 8 digits. The devices can be programmed via SPI, QSPI, and Microwire as well as a conventional 4-wire serial interface. The devices include an integrated BCD code-B/HEX decoder, multiplex scan circuitry, segment and display drivers, and a 64-bit memory. Internal memory stores the LED settings, eliminating the need for continuous device reprogramming.
