AD6311

1/8- to 1/16 Duty VFD Controller/Driver

ꢀ Function Description

1.0 Command

A command sets the display mode and status of the VFD driver. The first 1 byte input to the AD6311

through the Din pin after the STB pin has fallen is regarded as a command. If STB is made high while a

command/data is transmitted, serial communication is initialized, and the command/data being

transmitted is invalid (however, the command/data already transmitted remains valid).

1.1 Display mode setting command

This command initializes the AD6311 and selects the number of segments and number of grids (8 grid

& 20 segments to 16 grid & 12 segments). When this command is executed, display is forcibly turned

off, and key scanning is also stopped. To resume display, a display ON command must be executed. If

the same mode is selected, however, nothing is performed.

0xxx : 8 digits, 20 segments

1000: 9 digits, 19 segments

1001: 10 digits, 18 segments

1010: 11 digits, 17 segments

1011: 12 digits, 16 segments

1100: 13 digits, 15 segments

1101: 14 digits, 14 segments

1110: 15 digits, 13 segments

1111: 16 digits, 12 segments

On power application, the 16-digit, 12-segment mode is selected.

1.2 Data setting command

This command sets data write and data read modes. On power application, the normal operation mode

and address increment mode are set.
