7 PIN FUNCTIONS

7.1 ROW 0 to ROW 47 row driver outputs

These pads output the display row signals.

7.2 COL 0 to COL 83 column driver outputs

These pads output the display column signals.

7.3 VSS1 and VSS2: negative power supply rails

Negative power supply rails VSS1 and VSS2 must be

connected together, hereafter referred to as VSS. When a

pin has to be connected externally to VSS, then pin VSS1

should be used.

7.4 VDD1 to VDD3: positive power supply rails

Positive power supply rails: VDD1 for logic supply, VDD2 and

VDD3 for voltage multiplier. VDD2 and VDD3 must be

connected together, hereafter referred to as VDD2.

7.5 VLCDOUT, VLCDIN and VLCDSENSE: LCD power

supply

If the internal VLCD generator is used, then all three pins

must be connected together. If not (VLCD generator is

disabled and an external voltage is applied to VLCDIN), then

VLCDOUT must be left open-circuit, VLCDSENSE must be

connected to VLCDIN, VDD2 and VDD3 should be applied

according to the specified voltage range. The following

settings are also required: HVE = 0, S1 = 1 and S0 = 0.

7.6 VOS4 to VOS0: calibration inputs

Five pull-up input pins for on-glass VLCD calibration. Each

pin may be connected to VSS, which corresponds to

logic 0, or left open-circuit, which corresponds to logic 1.

All five pins define a 5-bit two’s complement number

ranging from −16 to 15 decimal (from 10000 to 01111).

The default value, with all pins connected to VSS, is

0 decimal (00000).
