7134LA25PDGI

Overview

The 7134LA25PDGI is a high-speed 32Kbit (4K x 8) dual-port static RAM manufactured by Renesas Electronics. It features fully asynchronous operation with a 25 ns access time, supporting simultaneous independent access to memory locations from two ports. The device operates on a single 5V power supply within the 4.5V to 5.5V range and includes an automatic power-down feature controlled by chip enable signals for low standby current. It is housed in a 48-pin PDG surface-mount package and supports industrial temperature ranges.

Feature Summary

• True dual-ported memory cells enabling simultaneous access to the same location without hardware arbitration
• Fully asynchronous operation allowing flexible timing control from either port
• Automatic power-down mode controlled by CE inputs for reduced standby power consumption

Applications

• Systems requiring external arbitration or contention handling for dual-port memory access
• Legacy embedded systems needing fast parallel SRAM interfaces
• Industrial applications requiring wide operating temperature ranges

Procurement Notes

Verify RoHS compliance status and lead times directly with authorized distributors as availability varies. Confirm package integrity upon receipt. Check for recent Product Change Notices regarding pinout or electrical specification updates. Ensure proper ESD handling during installation. Validate compatibility with existing system voltage levels before integration.

Selection Notes

Select this component when true dual-port functionality with asynchronous timing is required. Suitable for designs where external arbitration logic is preferred over on-chip conflict resolution. Consider the 48-pin PDG package constraints for PCB layout. Verify that the 25 ns access speed meets system timing requirements. Ensure the 5V supply voltage aligns with the target platform's power architecture.

Part Context

Part of the 7134LA series of high-speed dual-port SRAMs. Designed for applications demanding independent read/write operations from two distinct ports. Offers battery backup capability for data retention. Available in various packages including DIP, LCC, and surface-mount options to suit different form factors and assembly methods.

Replacement Considerations

IDT7134LA25PDGI is a confirmed substitute part number.
