7132SA20PDG

Overview

The Renesas Electronics Corporation 7132SA20PDG is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits organized as 2K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in a 48-pin plastic dual in-line package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems
• Asynchronous parallel interface for straightforward integration into standard digital logic designs
• CMOS technology construction ensuring low power consumption relative to older bipolar alternatives

Applications

• High-speed data buffering between microprocessors and peripheral devices
• Cache memory implementation in embedded control systems
• Data logging applications requiring rapid write and read cycles

Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm RoHS compliance requirements against specific project regulations, as legacy variants may differ. Validate pinout compatibility with existing PCB footprints before procurement. Check for available datasheets confirming electrical characteristics for the specific manufacturing batch.

Selection Notes

Select this component when dual-port functionality is required for concurrent system access. Ensure the 48-pin DIP package fits the mechanical constraints of the target enclosure. Verify that the 20ns access speed meets the timing requirements of the host processor bus. Consider alternative packages if surface-mount technology is preferred over through-hole assembly.

Part Context

This part belongs to the Renesas 7132 series of dual-port SRAMs. The series offers various access speeds and package options to suit different performance and form factor needs. The 7132SA variant specifically denotes the 20ns speed grade within the standard temperature range family.

Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pin configuration and logical functionality.
