7134LA25P

Overview

The Renesas Electronics 7134LA25P is a high-speed, 32-kbit (4K x 8) dual-port static random-access memory. It features fully asynchronous parallel operation with a maximum access time of 25 ns. The device operates on a single 5V power supply within a range of 4.5 V to 5.5 V and supports battery backup data retention down to 2 V. It utilizes true dual-ported memory cells allowing simultaneous independent access from either port without internal arbitration.

Feature Summary

• Supports simultaneous independent read/write operations from two separate ports using true dual-ported memory cells
• Enables automatic low-power standby mode through chip enable control for each individual port
• Provides TTL-compatible logic levels with a single 5V power supply requirement
• Allows external contention handling or arbitration when both ports access the same memory location

Applications

• Systems requiring simultaneous independent access to shared data buffers
• High-speed digital signal processing architectures needing non-blocking memory access
• Industrial control systems operating in environments with temperature ranges from -40°C to +85°C
• Battery-backed memory circuits requiring data retention at reduced voltage levels

Procurement Notes

Verify the specific package variant against project requirements as the base model number may correspond to multiple physical packages such as DIP or PLCC. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check current lifecycle status to ensure availability matches production timelines. Validate pinout compatibility with existing PCB footprints before finalizing procurement decisions.

Selection Notes

Select this component when true dual-port functionality is required without internal hardware arbitration. Ensure the system design can handle potential bus contention during simultaneous accesses. Verify that the 25 ns access speed meets the timing constraints of the target application. Consider the industrial temperature range if the deployment environment exceeds standard commercial limits.

Part Context

This part belongs to the 7134LA series of dual-port SRAMs manufactured by Renesas Electronics. It is designed for applications where external arbitration is preferred over internal conflict resolution. The LA suffix typically denotes industrial temperature range capabilities and specific power characteristics compared to other series variants.
