AS1106, AS1107

Data Sheet - Detailed Description

Shutdown Mode

The AS1106/AS1107 devices feature a shutdown mode, where they consume only 10µA (max) current. Shutdown

mode is entered via a write to the Shutdown Register (see Table 8). For the AS1106, at that point, all segment current

sources are pulled to ground and all digit drivers are connected to VDD, so that all segments are blanked. The AS1107

behavior is identical except the drivers are high impedance.

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 VDD (CMOS logic level).

The devices need typically 250µs to exit shutdown mode, and during shutdown mode the AS1106/AS1107 is fully pro-

grammable. Only the display test mode (see page 11) overrides shutdown mode.

When entering or leaving shutdown mode, the Feature Register is reset to its default values (all 0s) when Shutdown

Note: If the AS1106/AS1107 is used with an external clock, Shutdown Register bit D7 should be set to 1 when writing

to the Shutdown Register.

Digit- and Control-Registers

The AS1106/AS1107 devices contain 8 Digit-Registers and 6 control-registers, which are listed in Table 7. All registers

are selected using a 4-bit address word, and communication is done via the serial interface.

ꢀ

Digit Registers – These registers are realized with an on-chip 64-bit memory. Each digit can be controlled directly

without rewriting the whole register contents.

Control Registers – These registers consist of decode mode, display intensity, number of scanned digits, shut-

down, display test and features selection registers.
