X1240

Real Time Clock/Calendar with EEPROM

DESCRIPTION

2-Wire

™

RTC

FEATURES

• 2-wire interface interoperable with I

—400kHz data transfer rate

• Secondary power supply input with internal

switch-over circuitry

• 2Kbytes of EEPROM

—64-byte page write mode

—3-bit Block Lock

™

protection

• Low power CMOS

—<1µA operating current

—<3mA active current during program

—<400µA active current during data read

• Single byte write capability

• Typical nonvolatile write cycle time: 5ms

• High reliability

• Small package options

—8-lead SOIC package, 8-lead TSSOP package

The X1240 is a Real Time Clock with clock/calendar

circuits. The dual port clock register allows the clock to

operate, without loss of accuracy, even during read and

write operations.

The clock/calendar provides functionality that is con-

trollable and readable through a set of registers. The

clock, using a low cost 32.768kHz crystal input, accu-

rately tracks the time in seconds, minutes, hours, date,

day, month and years. It has leap year correction and

automatic adjustment for months with less than 31

days.

The device offers a backup power input pin. This

BACK

pin allows the device to be backed up by a non-

rechargeable battery. The RTC is fully operational from

1.8 to 5.5 volts.

The X1240 provides a 2Kbyte EEPROM array, giving a

safe, secure memory for critical user and conﬁguration

data. This memory is unaffected by complete failure of

the main and backup supplies.
