7132LA55C

Overview

The Renesas Electronics Corporation 7132LA55C is a static random access memory (SRAM) device belonging to the 7132 series. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The component utilizes a parallel interface with an asynchronous operation type and single data rate (SDR) storage technology. Key electrical parameters include a maximum access time of 55 ns, a supply voltage range from 4.5 V to 5.5 V, and a maximum power supply current of 140 mA. It supports an operating temperature range from -55°C to +125°C and is housed in a CDIP-SB-48 package designed for through-hole mounting.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations by two processors
• CMOS technology providing high-speed asynchronous access capabilities
• Wide industrial operating temperature range suitable for demanding environments

Applications

• High-performance embedded systems requiring dual processor data sharing
• Industrial control applications operating in extreme temperature conditions
• Telecommunications equipment utilizing parallel SRAM interfaces

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements as indicated specifications may vary. Validate package integrity for the CDIP-SB-48 form factor. Ensure design-in compatibility with existing system voltage levels and thermal management strategies before procurement.

Selection Notes

Select this component for designs requiring robust dual-port memory in harsh thermal environments. Compare against standard commercial grade variants if extended temperature ranges are unnecessary. Evaluate pinout compatibility with legacy DIP footprints during PCB layout planning. Consider alternative packages if surface mount technology is preferred over through-hole installation.
