7134SA20P

Overview

The Renesas Electronics Corporation 7134SA20P is a dual-port static random-access memory (SRAM) integrated circuit. It features an asynchronous parallel interface with a storage capacity of 32 kilobits, organized as 4K words by 8 bits. The device supports a maximum access time of 20 nanoseconds and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 48-pin plastic dual in-line package (PDIP) designed for through-hole mounting. The component functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface supporting standard logic levels
• High-speed data access capabilities suitable for real-time processing applications

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller architectures
• FIFO buffer construction for communication interface synchronization

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status prior to integration, as older variants may not meet current environmental regulations. Ensure the procurement channel provides traceability for this discontinued component series.

Selection Notes

Select this component when a design requires independent dual-port memory access without complex arbitration logic. Consider the 48-pin DIP package constraints for PCB layout and mechanical clearance. Evaluate the 20ns access speed against system timing requirements to ensure adequate performance margins for the target application frequency.
