6.1 Pin functions

6.1.1 R0 TO R64: ROW DRIVER OUTPUTS

These pins output the row signals.

6.1.2 C0 TO C101: COLUMN DRIVER OUTPUTS

These pins output the column signals.

6.1.3 VSS1 AND VSS2: GROUND SUPPLY RAILS

The supply rails VSS1 and VSS2 must be connected

together.

6.1.4 VDD1, VDD2 AND VDD3: SUPPLY VOLTAGE RAILS

VDD2 and VDD3 are the supply voltage for the internal

voltage generator. Both have the same voltage and should

be connected together outside the chip. VDD1 is used as

supply voltage for the rest of the chip. VDD1 can be

connected together with VDD2 and VDD3 but in this case

care must be taken to respect the supply voltage range

(see Chapter 11).

If the internal voltage generator is not used the pins

VDD2 and VDD3 must be connected to pin VDD1 or

connected to the supply voltage.

6.1.5 VLCDIN: LCD SUPPLY VOLTAGE

Positive supply voltage for the liquid crystal display. An

external LCD supply voltage can be supplied using

pin VLCDIN. In this case, VLCDOUT has to be left open and

the internal voltage generator has to be programmed to

zero. If the OM6206 is in Power-down mode, the external

LCD supply voltage has to be switched off.

6.1.6 VLCDOUT: VOLTAGE MULTIPLIER OUTPUT

Positive supply voltage for the liquid crystal display. If the

internal voltage generator is used, the two supply rails

VLCDIN and VLCDOUT must be connected together. If an

external supply is used this pin must be left open.

6.1.7

VLCDSENSE: VOLTAGE MULTIPLIER REGULATION

INPUT

VLCDSENSE is the input of the internal voltage multiplier

regulation.

If the internal voltage generator is used then VLCDSENSE

must be connected to VLCDOUT. If an external supply

voltage is used then VLCDSENSE can be left open or

connected to ground.

6.1.8 T1 TO T5: TEST PINS

T1, T3, T4 and T5 must be connected to VSS, T2 must be

left open. Not accessible to user.
