7132SA20J8

Overview

The Renesas Electronics Corporation 7132SA20J8 is a static random-access memory (SRAM) device organized as 2K x 8 bits, providing a total storage capacity of 16 kbit. It features a parallel interface with an access time of 20 ns and operates on a single 5V power supply ranging from 4.5 V to 5.5 V. The component utilizes a PLCC-52 surface-mount package and supports asynchronous operation within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling simultaneous independent access to memory cells by two separate processors or systems without bus contention.
• Integrated interrupt logic for signaling data availability or status conditions to the host system during read or write operations.

Applications

• High-speed data buffering in communication equipment requiring low-latency dual-controller access.
• Industrial control systems utilizing asynchronous parallel interfaces for real-time signal processing.
• Embedded applications needing dedicated dual-port memory for master-slave processor configurations.

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm moisture sensitivity level handling requirements prior to assembly. Check for end-of-life notices and available replacement components such as the 71321LA series. Validate package pinout compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when dual-port functionality with integrated interrupts is required for 2K x 8 bit memory expansion. Ensure the design accommodates the PLCC-52 package constraints and 20 ns access timing. Verify that the operating voltage range aligns with the system's 5V logic levels and thermal environment.

Part Context

This part belongs to the Renesas 7132SA family of high-speed dual-port SRAMs. It serves as a standalone solution for applications requiring concurrent access without external arbitration logic. The device complements other members of the family offering different speeds or capacities.
