Memory IC datasheet and documents for DS1250WP-150
Memory IC Overview
The DS1250WP-150 is a 4,194,304-bit nonvolatile SRAM organized as 524,288 words by 8 bits. It operates on a 3.3V supply with read and write access times of 100ns. The device features a self-contained lithium energy source that automatically switches on during power loss to protect data. It utilizes a 34-pin PowerCap Module package for surface mounting.
Memory IC Feature Summary
- Automatically protects data during power loss by switching to an internal lithium energy source
- Replaces volatile static RAM without requiring additional support circuitry
- Allows unlimited write cycles while maintaining low-power CMOS operation
- Features a replaceable snap-on PowerCap to prevent battery exposure to reflow soldering
Memory IC Applications
- Replacing 512k x 8 volatile static RAM in embedded systems
- Data storage applications requiring protection against power interruptions
- Surface-mount designs needing nonvolatile memory integration
Memory IC Procurement Notes
Verify the specific speed grade suffix matches system timing requirements. Confirm the PowerCap module is ordered separately as it is not included with the base module. Check RoHS compliance status if required by manufacturing standards. Ensure the operating temperature range aligns with the intended commercial or industrial environment.
Memory IC Selection Notes
Select this component when a direct replacement for 512k x 8 SRAM is needed with nonvolatile capabilities. The PowerCap package is suitable for surface-mount assembly processes. Verify that the 3.3V supply voltage is compatible with the target microprocessor interface. Consider the industrial temperature range option if operation outside standard commercial limits is necessary.
Memory IC Part Context
The DS1250W series integrates nonvolatile SRAM technology into a single package. The WP variant specifically denotes the PowerCap Module form factor designed for surface mounting. This family eliminates the need for external battery management circuits while providing immediate data retention upon power failure.
