7132LA25PDG

Overview

The Renesas Electronics Corporation 7132LA25PDG is a 16Kb (2K x 8) Dual-Port Static Random Access Memory (SRAM). It features asynchronous parallel interface operation with a maximum access time of 25 ns. The device operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. It utilizes a 48-pin DIP package and supports surface mount or through-hole installation styles depending on specific variant configurations, though this model specifies the PDG footprint. The component is designed for high-speed data storage applications requiring independent port access.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to the same memory location from two separate ports.
• Fully asynchronous operation allows flexible timing control for both read and write cycles without clock synchronization requirements.
• TTL-compatible logic levels simplify integration with standard digital systems using a single 5V power supply.

Applications

• Interprocessor communication buffers in multi-core or multi-microcontroller systems
• High-speed data buffering between disparate system components
• Dual-port memory expansion in industrial control architectures

Procurement Notes

Verify RoHS compliance status as legacy variants may differ. Confirm package pinout compatibility with existing PCB footprints. Check for moisture sensitivity handling requirements during storage and assembly. Ensure voltage specifications match target system rails. Validate lead availability due to potential end-of-life status.

Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Compare access times against system timing constraints. Evaluate package size limitations against available board space. Consider thermal dissipation characteristics for enclosed environments. Verify interrupt flag support if inter-port signaling is needed.

Part Context

This part belongs to the 7132LA series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various access speeds and package options to suit different performance and form factor requirements. These devices are commonly used in embedded systems requiring reliable, fast memory sharing between processors.

Replacement Considerations

IDT7132LA25PDG is a confirmed substitute part number. Verify pin compatibility and electrical parameters before substitution. Ensure mechanical dimensions match the original design constraints.
