7132SA35J

Memory IC Overview

The Renesas Electronics Corporation 7132SA35J is a high-speed, dual-port static random-access memory (SRAM) device. It features a storage capacity of 16 kilobits organized as 2K by 8 bits. The component utilizes a parallel interface with an access time and write cycle time of 35 nanoseconds. It operates on a single 4.5V to 5.5V power supply and supports surface-mount installation in a 52-pin PLCC package measuring 19.13x19.13 mm. The device functions within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from both ports without external arbitration logic.
• Includes on-chip port arbitration logic to manage bus conflicts during concurrent access attempts.
• Features automatic power-down control via chip enable signals for low standby power consumption.
• Provides a BUSY output flag to indicate when a port is busy accessing shared memory.

Memory IC Applications

• Stand-alone 8-bit dual-port memory systems
• Master dual-port RAM configurations in 16-bit or wider word width systems
• High-speed data buffering applications requiring concurrent read/write operations

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as original specifications may differ from current manufacturing standards. Validate package integrity upon receipt. Ensure proper handling procedures are followed for static-sensitive devices. Cross-reference datasheet revisions before final integration.

Memory IC Selection Notes

Select this component for designs requiring true dual-port functionality with minimal external logic overhead. Consider the 52-PLCC package constraints for PCB layout. Evaluate thermal performance within the specified commercial temperature range. Compare against newer generations if long-term supply assurance is critical for production lifecycles.
