Description

The PT7C4363 serial real-time clock is a low-power

clock/calendar with a programmable square-wave output.

Address and data are transferred serially via a 2-wire

bidirectional bus. The clock/calendar provides seconds,

minutes, hours, day, date, month, and year information.

The date at the end of the month is automatically

adjusted for months with fewer than 31 days, including

corrections for leap year. The clock operates in the 24-

hour format indicator.

Data Sheet

PT7C4363

Real-time Clock Module (I

C Bus)

Function Description

Overview of Functions

Clock function

CPU can read or write data including the year (last two digits), month, date, day, hour, minute, and second. Any (two-digit) year

that is a multiple of 4 is treated as a leap year and calculated automatically as such until the year 2100.

Alarm function

These devices have one alarm system that outputs interrupt signals from INTA for PT7C4363 or INT/OUT/SQW for PT7C4341

to CPU when the date, day of the week, hour, minute or second correspond to the setting. Each of them may output interrupt

signal separately at a specified time. The alarm may be selectable between on and off for matching alarm or repeating alarm.

Programmable square wave output

A square wave output enable bit controls square wave output at pin 7. 4 frequencies are selectable: 1, 32, 1.024k, 32.768k Hz.

Interface with CPU

Data is read and written via the I

C bus interface using two signal lines: SCL (clock) and SDA (data).

Since the output of the I/O pin SDA is open drain, a pull-up resistor should be used on the circuit board if the CPU output I/O is

also open drain.

The SCL's maximum clock frequency is 400 kHz, which supports the I

C bus's high-speed mode.

Oscillator fail detect

When oscillator fail, OSF bit will be set.

Oscillator enable/disable

Only time count chain can be enable or disable by STOP bit..

Timer function

The timer control register determines one of 4 source clock frequencies for the timer (4096 Hz, 64 Hz, 1 Hz, or 1/60 Hz) and

enables or disables the timer. The timer counts down from software loaded 8-bit binary value. At the end of every countdown, the

timer sets the Timer Flag (TF). The TF may only be cleared by software. The asserted TF can be used to generate an interrupt.

The interrupt may be generated as a pulsed signal every countdown period or as a permanently active signal which follows the

condition of TF. Bit TI/TP is used to control this mode selection. When reading the timer, the current countdown value is returned.

Reset function

The PT7C4363 includes an internal reset circuit which is active whenever the oscillator is stopped. In the reset state the I

C-bus

logic is initialized and all registers, including the address pointer, are cleared with the exception of bits FE, OSF, TD1, TD0,

TESTC and AE which are set to logic 1.
