Overview

IZ1325 High-precision Real Time Clock circuit with thermal compensation and built-in quartz resonator (Functional analogue of RX8025SA by Company « Epson Toyocom ») The IZ1325 high-precision real-time clock circuit with thermal compensation and built-in quartz resonator, provides high accuracy counting the current time of the, generation of 6 system interruptions and two independent event signals.
The device provides both 24/12-hour operation modes and contains the built-in supply control circuit, frequency adjustment circuit for high accuracy of the system generator.
The IZ1325 support data and command exchange by means of standard 2-wire interface (I2C-bus).
The IC is applied in the wide range of the industrial and household equipment and appliances, where it is required to counting and processing of the system current time data.
Main functions: • seconds, minites hours, weekday, date, month and year time counting; • two operational modes12/24-hours; • data and command exchange via 2-wire I2C-bus serial interface; • 6 system interrupts generation; • 2 independent alarms: day, hours, minutes and hours, minutes; • supply voltage and system generator frequency monitoring.
Main features: • Supply voltage, UDD, 1,7 … 5,5 V • Oscilator operating supply voltage UCLK, 1,15 … 5,5 V • Operating temperature range -40 to +85 °С Table 1 – Contact pad description Contact pad num- ber 01 02 03 04 05 06 07 08 09 10 11 Symbol GND INTA X1 X2 FOE VDD TEST FOUT SCL SDA INTB Description Ground Interrupt output A Quartz resonator input Quartz resonator output Control input Power supply Test terminal 32.
