Introduction

The

consists

of

six

(LH1552F)

and

a

com-

(LH1553F).

The

has

240

circuits

and

operates

under

The

driver

has

168

internal

driver

circuits.

To

abate

the

CPU

load,

connection

is

made

only

to

the

common

driver,

and

the

common

driver

transfers

data

with

a

several

(8

maxi-

mum)

segment

drivers.

The

8-bit

display

data

received

from

the

CPU

are

sent

to

the

common

driver,

and

sent

"after

completing

processing

Introduction

The

SMC5245

is

a

calendar

combined

real

time

clock.

It

has

a

basic

frequency

of

32,768Hz

generated

from

a

crystal

oscillator

to

produce

second,

minute,

hour,

day,

day

of

week,

month,

and

year.

It

has

an

automatic

leap

year

interrogating

feature

of

the

world

calendar,

cyclic

interrupt

feature,

2-channel

alarm

feature,

and

a

4-channel

external

voltage

detect

feature.

For

interfacing

with

a

microcomputer,

it

uses

8-bit

data

bus,

5-bit

address

bus,

3-bit

chip

select

and

read/write

signals,

allowing

to

set

time,

alarm,

interrupt

and

to

read

time,

interrupt

cause,

and

voltage

detect

result.

A

part

of

the

oscillation

circuit

and

the

frequency

divider

are

driven

by

a

low

voltage

for

a

low

power

consumption.

5)

Pin

functions

@

D0~D7:

8-bit

data

bus

These

are

bidirectional

data

bus

that

connected

with

the

microcomputer

data

bus

and

used

to

read/write

counters

and

registers.

The

data

bus

is

at

a

high

impedance

except

when

CS0~CS2

is

active

and

R/W

is

at

a

high.

@

A0~A4:

5-bit

address

bus

These

are

address

input

lines

that

are

within

the

microcomputer

address

bus

and

used

to

assign

read/write

counters

and

registers.

@

CS0~CSS5:

5-bit

address

bus

These

are

chip

select

lines

used

to

set

active

and

inactive

the

IC.

Normally,

address

decoded

signal

is

connected.

CSO

is

an

active

low

signal.

CS1

and

CS2

are

active

high

or

low

that

can

be

selected

by

masking.

The

IC

becomes

active

when

the

3-bit

select

line

has

turned

active.

®

Read/Write

pin

The

contents

of

the

counter

and

the

register

designated

in

ad-

dress

AO~A4

at

HIGH

level

are

outputted

to

the

data

bus.

Writing

is

performed’

at

LOW

level.

When

CS0~CS2

are

non-active,

neither

read

nor

write

can

be

made.

©

ALARM

interrupt

output

pin

—

Cyclic

interrupt,

alarm

interrupt,

and

voltage

detect

interrupt

are

informed

to

the

external

source.

With

a

mask

option,

active

low

or

high

state

can

be

selected.

Only

the

software

can

be

assigned

to

set

this

line

for

set

active

or

anaenve:

These

lines

are

not

affected

by

CS0~CS2.

RESET

reset

pin

This

line

is

used

to

initialize

the

IC.

A

high

on

this

line

initializes

all

register

contents.

In

addition

to

this

function,

it

also

has

an

internal

power-on-reset

circuit.

The

reset

is

OR’ed

with

the

power-on-reset

circuit.

Internal

pulldown

is

not

provided

on

the

reset

line.

NOTE:

The

power-on-reset

circuit

may

not

start

active

depending

on

how

the

power

is

turned

on.

@®

TEST

test

pin

Only

Seiko

Epson

may

provide

it

for

test

of

the

IC.

Normally,

it

is

internally

pulled

down.

It

is

suggested

to

connect

with

VSS

exter-

nally.

6)

User

circuit

The

user

circuit

consists

of

14

input/output

lines.

ONKEY,

RSKEY,

and

BTCOV

lines

are

Schmitt

trigger

inputs

that

normally

pulled

down

internally.

The

one-shot

circuit

issues

a

high

level

signal

(normally

low)

to

the

8/512~9/512

one-shot

circuit

at

a

high

to

low

transition

of

the

BTCOV

line.

The

one-shot

circuit

has

a

trigger.

The

one-shot

circuit

output-2

has

a

delay

of

1/2024~3.1024

second

and

continues

to

sent

high

level

until

the

BTCOV

line

becomes

high

(normally

low).

The

VDA

signal

is

an

output

from

the

voltage

detector

A.

A

high

level

signal

is

issued

when

normal

(voltage

found).

This

signal

is

at

a

high

at

a

time

of

initialization.

The

NADOCW

signal

is

an

active

low

ad-

dress

0CH

write

signal.

The

DFR

signal

is

a

register

of

a

user

bit

that

sends

the

input

level

of

D

to

Q

at

a

low

to

high

transition

of

signal.

When

a

low

level

signal

is

received

by

R,

the

DFR

is

reset

with

a

low

level

signal

sent

to

Q.

(XQ

is

an

invert

output

of

Q).
