Overview
The 27S185ALM/B is a One-Time Programmable (OTP) Read-Only Memory integrated circuit manufactured by Rochester Electronics, LLC. It features a 2K x 4-bit bipolar architecture, providing non-volatile data storage suitable for legacy system maintenance. The device is designed to sustain existing technologies that would otherwise become obsolete, ensuring continued production of fully licensed and tested products. This component serves as a direct replacement for original AM27S185 units in industrial and commercial applications requiring stable, long-term memory solutions.
Feature Summary
- One-time programmable non-volatile memory architecture
- Bipolar technology implementation for reliable operation
- Legacy component sustainability support
Applications
- Industrial control systems requiring legacy memory
- Motor control cabinets with established designs
- Obsolete electronic equipment maintenance
Procurement Notes
Verify the specific suffix 'LM/B' against your system requirements, as it denotes package and temperature variants. Confirm authenticity through authorized channels, as Rochester Electronics distributes genuine, factory-sealed components. Check date codes to ensure recent manufacturing standards. Ensure compatibility with existing board layouts and voltage levels before procurement.
Selection Notes
Select this component when replacing failed OTP ROMs in systems originally designed around the AM27S185. It is appropriate for applications where data programming has already occurred and only read access is needed. Consider the bipolar technology characteristics for thermal and switching behavior. Ensure the physical package matches the existing footprint on the printed circuit board.
Part Context
Rochester Electronics specializes in sustaining obsolete semiconductor technologies rather than developing new ones. They maintain extensive wafer and die banks to manufacture over 70,000 device types. This company acts as a critical source for discontinued parts, ensuring supply continuity for industries relying on older microprocessors, memory, and logic devices that are no longer produced by original manufacturers.
Replacement Considerations
Direct substitute part numbers include 27S185ADM/B from Rochester Electronics. Verify pinout compatibility and electrical specifications before swapping. Ensure the replacement unit meets the same environmental and performance standards as the original design.
