7132LA25PDG

Memory IC 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.

Memory IC 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.

Memory IC 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

Memory IC 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.

Memory IC 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.
