Shutdown Mode
The AS1116 devices feature a shutdown mode, where they consume only 200nA (typ) current. Shutdown mode is
entered via a write to the Shutdown Register (see
and digital drivers are switched off, so that all segments are blanked.
Note: During shutdown mode the Digit-Registers maintain their data.
Shutdown mode can either be used as a means to reduce power consumption or for generating a flashing display
(repeatedly entering and leaving shutdown mode). For minimum supply current in shutdown mode, logic input should
be at GND or V
When entering or leaving shutdown mode, the Feature Register is reset to its default values (all 0s) when Shutdown
Register bit D7 (page 10) = 0.
Note:
Digit- and Control-Registers
The AS1116 devices contain 8 Digit-Registers,11 control-registers and 8 diagnostic-registers, which are listed in
7. All registers are selected using a 8-bit address word, and communication is done via the serial interface.
