2.1.2 Function pins

Each function pin except I/O ports is described below.

(1) Pins VCC and VSS

Power source input pins. In the high-speed mode, apply (

+ 2) V–5.5 V to the VCC pin.

In the middle-speed mode or the low-speed mode, apply 2.5 V–5.5 V to the VCC pin.

In all modes, apply 0 V to the VSS pin.

(2) Pins VL1, VL2 and VL3

Power source input pins for LCD. Apply 0

≤ VL1 ≤ VL2 ≤VL3 ≤ VCC of voltage to these pins.

(3) Pins XIN and XOUT

An input pin and an output pin for the main clock generating circuit.

(4) RESET pin

The 3820 group is reset internally by keeping the level of this pin at “L” for 2

µs or more. Reset state

is released by returning the level of this pin to “H”.

(5) Pins SEG0 to SEG15

Segment signal output pins for LCD.

(6) Pins COM0 to COM3

Common signal output pins for LCD.

When Ta = –40

°C to –20 °C, use the extended operating temperature version, and apply

3.0 V–5.5 V to the VCC pin.
