ISL12032

Real Time Clock with 50/60 Hz clock and Crystal Backup

Data Sheet

December 14, 2007

FN6618.0

Low Power RTC with Battery Backed

SRAM and 50/60 Cycle AC Input and Xtal

Back-up

Features

• 50/60 Cycle AC as a Primary Clock Input for RTC Timing

• Redundant Crystal Clock Input Selectable by User

- Dynamically Switch from AC Clock Input to Crystal in

Case of Power Failure

The ISL12032 device is a low power real time clock with

50/60 AC input for timing synchronization. It also has an

oscillator utilizing an external crystal for timing back-up,

clock/calendar registers, intelligent battery back-up

switching, battery voltage monitor, brownout indicator,

integrated trickle charger for super capacitor, single periodic

or polled alarms, POR supervisory function, and up to 4

Event Detect with time stamp. There are 128 bytes of

battery-backed user SRAM.

• Real Time Clock/Calendar

- Tracks Time in Hours, Minutes, Seconds and tenths of a

second

- Day of the Week, Day, Month, and Year

• Auto Daylight Saving Time Correction

- Programmable Forward and Backward Dates

• Security and Event Functions

The oscillator uses a 50/60 cycle sine wave input, backed by

an external, low-cost, 32.768kHz crystal. The real time clock

tracks time with separate registers for hours, minutes, and

seconds. The calendar registers contain the date, month,

year, and day of the week. The calendar is accurate through

year 2100, with automatic leap year correction and auto

daylight savings correction.

- Event Detection with Time Stamp

- Stores First and Last Three Event Time Stamps

• Separate F

- 7 Selectable Frequency Outputs

• Dual Alarms with Hardware and Register Indicators

- Hardware Single Event or Pulse Interrupt Mode

• Automatic Backup to Battery or Super Capacitor

- VBAT Operation Down to 1.8V

Pinout

- 1.0µA Battery Supply Current
