DESCRIPTION 

The DS1689/DS1693 are real-time clocks (RTCs) designed as successors to the industry standard DS1285, DS1385, DS1485, and DS1585 PC real-time clocks. These devices provide the industry standard DS1285 clock function with the new feature of either +3.0V or +5.0V operation and automatic backup and write protection to an external SRAM. The DS1689 also incorporates a number of enhanced features including a silicon serial number, power-on/off control circuitry, and 114 bytes of user NV SRAM, power-on elapsed timer, and power-cycle counter. 

FEATURES

Incorporates Industry Standard DS1287 PC Clock Plus Enhanced Features:

- +3V or +5V Operation

- 64-Bit Silicon Serial Number

- 64-Bit Customer Specific ROM or Additional Serial Number Available

- Power Control Circuitry Supports System Power-On from Date/Time Alarm or Key Closure

- Automatic Battery Backup and Write Protection to External SRAM

- Crystal Select Bit Allows RTC to Operate with 6pF or 12.5pF Crystal

- 114 Bytes User NV RAM

- Auxiliary Battery Input
