7132LA55L48B

Overview

The Renesas Electronics Corporation 7132LA55L48B is a dual-port static random-access memory (SRAM) device. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The component supports asynchronous parallel interface operation with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 140 mA. The device is designed for through-hole mounting in a CDIP-SB-48 package. It functions reliably across an extended industrial temperature range from -55 °C to +125 °C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous parallel interface for straightforward system integration
• Extended industrial temperature rating suitable for harsh environments

Applications

• High-reliability industrial control systems
• Automotive electronic control units requiring wide temperature tolerance
• Telecommunications infrastructure equipment
• Military and aerospace embedded memory applications

Procurement Notes

Verify the specific suffix L48B against official Renesas documentation to confirm the lead frame material and RoHS compliance status, as legacy variants often differ. Confirm package integrity for the CDIP-SB-48 form factor during inspection. Check for obsolescence notices or last-time buy notifications directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for shared data buffering between independent processing cores. The 55 ns access speed suits moderate-frequency asynchronous buses. Ensure the design accommodates the through-hole CDIP-SB-48 footprint and provides adequate thermal management for the specified operating temperature range up to 125 °C.

Part Context

This part belongs to the Renesas 7132 series of dual-port SRAMs, originally developed under IDT branding. These devices are engineered for high-speed data exchange in complex digital systems. The LA variant typically denotes enhanced performance or specific packaging characteristics compared to standard SA versions, targeting robust industrial and automotive sectors.

Replacement Considerations

Consult official Renesas cross-reference guides for verified equivalents. Potential substitutes may include other 16Kb dual-port SRAMs with matching pinouts and electrical specifications. Verify that any replacement maintains the CDIP-SB-48 package dimensions and meets the -55 °C to +125 °C temperature requirements.
