7133LA25PF

Overview

The 7133LA25PF is a 32 Kbit (2K x 16) CMOS dual-port static random-access memory manufactured by Renesas Electronics. It features asynchronous parallel interface with a maximum access time of 25 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation in a 100-TQFP package. It is designed for industrial temperature ranges, typically spanning from 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation compatible with various system clock speeds
• CMOS technology ensuring low power consumption during standby and active modes

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control networks requiring dual-processor access

Procurement Notes

Verify the specific suffix requirements against your design needs, as packaging variations exist between tape-and-reel and tray formats. Confirm RoHS compliance status for your region's regulatory standards. Ensure the selected variant matches the required operating temperature range and pinout configuration for your PCB layout.

Selection Notes

Select this component when a 32 Kbit capacity with 16-bit word width is required. The 25 ns speed grade suits applications needing moderate latency without the complexity of synchronous interfaces. Consider the 100-pin package density for space-constrained designs requiring dual-port functionality.

Part Context

This part belongs to the 7133LA series of dual-port SRAMs, which are widely used in legacy and current industrial designs. It serves as a direct replacement for older IDT equivalents, maintaining pin compatibility while offering updated manufacturing processes. The series is known for reliability in harsh environments.

Replacement Considerations

Direct pin-compatible substitutes include the 7133SA25PFG and 7133LA20PFG variants, though speed and temperature grades differ. Verify that any alternative meets the exact voltage and timing specifications required by your circuit design.
