DS1250WP-100IND+

Memory IC Overview

The DS1250WP-100IND+ is a 4,194,304-bit nonvolatile SRAM organized as 524,288 words by 8 bits. It operates at 3.3V with read and write access times of 100ns. The device features an industrial temperature range of -40°C to +85°C and utilizes a 34-pin PowerCap Module package. Data retention is guaranteed for a minimum of 10 years without external power.

Memory IC Feature Summary

• Automatically protects data during power loss by switching to an internal lithium energy source
• Replaces volatile static RAM, EEPROM, or Flash memory with unlimited write cycles
• Ships with the lithium energy source electrically disconnected to retain freshness until first power application

Memory IC Applications

• Replacing existing 512k x 8 static RAMs in microprocessor systems
• Surface-mountable nonvolatile storage modules requiring replaceable battery backup
• Industrial applications requiring extended temperature operation

Memory IC Procurement Notes

Verify that the DS9034PC+ or DS9034PCI+ PowerCap is ordered separately, as it is required to complete the module. Confirm the IND suffix indicates the industrial temperature range (-40°C to +85°C). Ensure the 34-pin PowerCap Module package aligns with surface-mount design requirements rather than through-hole DIP layouts.

Memory IC Selection Notes

Select this component when a surface-mount NVSRAM solution is needed with replaceable battery capabilities. The 100ns speed grade suits standard parallel interface timing. Verify compatibility with 3.3V logic levels and ensure the design accommodates the separate ordering of the snap-on PowerCap battery module.

Memory IC Part Context

This part belongs to the DS1250W series of 3.3V Nonvolatile SRAMs. It integrates SRAM memory and nonvolatile control into a module base, allowing direct surface mounting without subjecting the lithium backup battery to high-temperature reflow soldering. The PowerCap Module design facilitates easy removal using a regular screwdriver.

Memory IC Replacement Considerations

Direct replacements include other DS1250W series variants such as the DS1250W-100IND+ (DIP package) or different speed grades like the DS1250W-70IND+. Ensure the replacement maintains the 34-pin PowerCap Module form factor if board space and mounting style are critical constraints.
