DS3065WP
3.3V, 8Mb, Nonvolatile SRAM with Clock
Includes All the Components Needed for a 1M x 8 Battery-Backed SRAM Module with a RTC in the Standard PowerCap Package
Overview
- Reflowable, 34-Pin PowerCap Package
- Integrated RTC
- Unconditionally Write Protects the Clock and SRAM When VCC is Out of Tolerance
- Automatically Switches to Battery Supply When VCC Power Failures Occur
- Industrial Temperature Range (-40°C to +85°C)
The DS3065WP consists of a static RAM, a nonvolatile (NV) controller, and a real-time clock (RTC). These components are packaged on a surface-mount substrate and require post-assembly attachment of a DS9034IPCX+ battery cap. Whenever VCC is applied to the module, it powers the clock and SRAM from the external power source, and allows the contents of the clock registers or SRAM to be modified. When VCC is powered down or out of tolerance, the controller write protects the memory contents and powers the clock and SRAM from the battery.
Applications
- Data-Acquisition Systems
- Industrial Controllers/PLCs
- POS Terminals/Fire Alarms
- RAID Systems and Servers/Gaming
- Routers/Switches
