Pin Description

Pin No.

Symbol

Name

Function

1

Power supply output

RAM and the like.

2

Backup power supply

input

Backup power supply is connected to this pin.

If a lithium battery is used, insert a resistor in series for safety purposes.

3

Power supply input

+3V input pin. Connect to a logic power supply.

4

Delay capacitor

connection pin

A delay capacitor is connected to this pin. By connecting a capacitor, it is

possible to delay each output.

5

RES

Positive reset output

Connect to the positive reset input of a microcontroller. The pin is

capable of flowing 1mA sink current.

6

GND

Ground

Reference for all signals.

7

RES

Negative reset output

Connect to the negative reset input of a microcontroller. The pin is

capable of flowing 1mA sink current.

8

CS

Chip select output

Connect to the

Chip Select of RAM. The CS output is at low level in

normal state thereby letting RAM be active. Under failure or backup

condition, the CS output is set to high level, then RAM enters standby

state disabling read/write function. The pin is capable of flowing a 1mA

sink current.
