• FRAM (Pin 38)

This is an input and output pin for the frame synchronizing signal to be used for master/slave

configuration. It becomes an output pin in master mode and an input pin in slave mode.

• SI (Pin 34)

This is a serial data input pin of address data (8 bits) and segment data (64 bits). A pull-up

resistor (10 kW - 60 kW) and the Schmitt circuit are contained. The serial data is shifted at the

rising edge of SCK.

• SCK (Pin 35)

This is a shift clock input pin of address data (8 bits) and segment data (64 bits). The serial data

is shifted at the rising edge of SCK pulse. A pull-up resistor (10 kW - 60 kW) and the Schmitt

circuit are contained.

• LATCH (Pin 32)

This is a latch pulse input pin of address data (8 bits) and segment data (64 bits). The latch data

comes through at "H" level of LATCH and the data just before "H" level is latched at "L" level.

A pull-up resistor (10 kW - 60 kW) and the Schmitt circuit are contained.

• A/D (Pin 33)

This is a data select signal input pin of address data (8 bits) and segment data (64 bits). "H" level

is set in the case of address 8-bit input and "L" level is set in the case of segment data 64-bit input.

A pull-up resistor (10 kW - 60 kW) and the Schmitt circuit are contained.

• VDSP (Pin 44), V1 (Pin 29), V2 (Pin 45), V3 (Pin 46), V4 (Pin 28), VCC (Pin 42), GND (Pin 43)

These are power supply pins for this LSI and bias power supply pins for LCD driving.

VCC, which is a power supply pin, is from 4.5V to 5.5V; GND, which is a ground pin, is 0V; VDSP,

which is an LCD driving power supply pin, is usually used in the range between 6V and 16V.

V1, V2, V3 and V4 are bias power supply pins for LCD driving and are usually used by

supplying bias voltage from an external source.
