V3020

Ultra Low Power 1-Bit 32 kHz RTC

Description

Features

The V3020 is a low power CMOS real time clock. Data is

transmitted serially as 4 address bits and 8 data bits, over

one line of a standard parallel data bus. The device is

Supply current typically 390 nA at 3V

50 ns access time with 50 pF load capacitance

Fully operational from 1.2V to 5.5V

accessed by chip select ( CS ) with read and write control

timing provided by either RD and WR pulse (Intel CPU)

No busy states or danger of a clock update while

accessing

or DS with advanced R/

W (Motorola CPU). Data can

Serial communication on one line of a standard

parallel data bus or over a conventional 3 wire serial

interface

also be transmitted over a conventional 3 wire serial

interface having CLK, data I/O and strobe. The V3020

has no busy states and there is no danger of a clock

Interface compatible with both Intel and Motorola

update while accessing.

Supply current is typically

Seconds, minutes, hours, day of month, month, year,

week day and week number in BCD format

390 nA at V_DD= 3.0V. Battery operation is supported by

complete functionality down to 1.2V. The oscillator is

typically 0.3 ppm/V.

Leap year and week number correction

Time set lock mode to prevent unauthorized setting of

the current time or date

Applications

Oscillator stability 0.3 ppm / volt

No external capacitor needed

Utility meters

Battery operated and portable equipment

Consumer electronics

White/brown goods
