7132LA55P

Overview

The Renesas Electronics Corporation 7132LA55P is a static random access memory device featuring a storage capacity of 16 kbit organized as 2K x 8. It operates with an access time of 55 ns and utilizes a parallel interface. The component supports a supply voltage range from 4.5 V to 5.5 V, with a maximum power consumption of 140 mA. Designed for through-hole installation, it is housed in a CDIP-SB-48 package. The device functions within an extended industrial temperature range spanning from -55°C to +125°C.

Feature Summary

• Dual-port asynchronous SRAM architecture enabling independent simultaneous read/write operations
• Extended industrial temperature rating suitable for harsh environmental conditions
• CMOS technology providing low power consumption characteristics

Applications

• Industrial control systems requiring reliable data storage
• Telecommunications equipment operating in extreme temperatures
• Military and aerospace electronic subsystems

Procurement Notes

Verify the specific suffix designation carefully, as the requested model differs from the available LA55CB variant. Confirm RoHS compliance status, as older variants may not meet current environmental standards. Check for end-of-life notices or obsolescence warnings before procurement. Ensure the CDIP-SB-48 package type matches the target PCB footprint requirements exactly.

Selection Notes

Select this component when dual-port functionality is required for high-speed data buffering between independent processors. The wide temperature range makes it suitable for applications exceeding standard commercial limits. Consider the through-hole mounting style if mechanical robustness is prioritized over board space efficiency compared to surface-mount alternatives.
