2902ADM/B

Overview

The 2902ADM/B is a non-volatile memory component manufactured by Rochester Electronics, LLC. It functions as a static random-access memory (SRAM) device designed for data storage applications requiring rapid access speeds and retention of information without power. The component is housed in a dual in-line package configuration suitable for through-hole mounting on printed circuit boards. This specific part number represents a variant within the broader 2902 family of memory products, offering standard logic levels and interface characteristics compatible with common microprocessor systems.

Feature Summary

• Non-volatile data retention capability ensuring stored information persists without continuous power supply
• Static RAM architecture providing fast read and write access times for high-speed processing
• Dual in-line package design facilitating straightforward integration into legacy and industrial electronic assemblies

Applications

• Embedded control systems requiring reliable temporary data storage
• Industrial equipment needing robust memory solutions for operational parameters
• Legacy system maintenance and replacement in existing hardware infrastructure

Procurement Notes

Verify the exact capacity and speed grade against original system specifications before procurement. Confirm package pinout compatibility with existing PCB footprints. Ensure environmental ratings meet operational requirements. Request manufacturer documentation to validate authenticity and traceability. Check for any specific handling instructions related to electrostatic discharge protection during installation.

Selection Notes

Select this component based on its specific memory architecture and package type required by the target application. Consider the operating temperature range and voltage supply requirements to ensure compatibility with the host system. Evaluate the need for non-volatile behavior versus standard volatile SRAM alternatives. Assess physical space constraints to confirm the dual in-line package fits the designated area. Review historical performance data if available for similar components in comparable environments.

Part Context

Rochester Electronics specializes in providing lifecycle solutions for semiconductors, including end-of-life and active parts. The 2902ADM/B falls under their portfolio of memory devices, supporting industries that require long-term availability of specific integrated circuits. As a distributor and manufacturer, Rochester ensures these components meet quality standards for critical applications where original OEM sources may no longer be available.

Replacement Considerations

Direct substitutes must match the 2902 series specifications exactly. Verify pin compatibility and electrical characteristics before swapping. Generic SRAM replacements may not offer identical timing or voltage profiles. Consult official cross-reference lists from Rochester Electronics for approved equivalent part numbers.
