V3022

Very Low Power 8-Bit 32 kHz RTC Module with Digital

Trimming and High Level Integration

Description

Features

The V3022 is a low power CMOS real time clock with a

built in crystal. Standby current is typically 1.2 µA and the

access time is 50 ns. The interface is 8 bits with

ꢀ Built-in crystal with digital trimming and temperature

compensation facilities

ꢀ 50 ns access time with 50 pF load capacitance

ꢀ Standby on power down typically 1.2 µA

ꢀ Wide voltage range, 2.0V to 5.5V

multiplexed address and data bus.

Multiplexing of

address and data is handled by the input line A /D. There

are no busy flags in the V3022, internal time update

cycles are invisible to the user's software. Time data can

be read from the V3022 in 12 or 24 hour data formats. An

external signal puts the V3022 in standby mode. Even in

ꢀ Universal interface compatible with both Intel and

Motorola

ꢀ Simple 8 bit interface with no delays or busy flags

standby, the V3022 pulls the IRQ pin active low on an

internal alarm interrupt. Calendar functions include leap

year correction and week number calculation. Time

precision can be achieved by digital trimming.

ꢀ Power fail input disables during power up / down of

reset

ꢀ Bus can be in tri-state in power fail mode

ꢀ 12 or 24 hour data formats

ꢀ Time to 1/100 of a second

Applications

ꢀ Leap year correction and week number calculation

ꢀ Alarm and timer interrupts

ꢀ Industrial controllers

ꢀ Alarm systems with periodic wake up

ꢀ PABX and telephone systems

ꢀ Point of sale terminals

ꢀ Automotive electronics

ꢀ Programmable interrupts: 10 ms, 100 ms, s or min

ꢀ Sleep mode capability

ꢀ Alarm programmable up to one month

ꢀ Timer measures elapsed time up to 24 hours

ꢀ Temperature range: -40°C to +85°C
