7133SA55PFI8

Overview

The Renesas Electronics Corporation 7133SA55PFI8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device supports parallel interface operations with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and is designed for surface-mount installation in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. The component is rated for commercial temperature operation between 0°C and +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous control logic eliminating the need for external clock signals
• CMOS technology providing low power consumption characteristics

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers

Procurement Notes

This specific part number is officially discontinued and no longer manufactured by Renesas Electronics. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Procurement should prioritize confirmed replacement components listed in official product discontinuance notifications to ensure long-term supply chain stability and compliance with design requirements.

Selection Notes

Designers requiring this component must evaluate the officially designated upgrade path due to end-of-life status. Selection criteria should focus on matching the original 32Kb capacity, 16-bit width, and 55ns speed grade. Compatibility checks are essential when transitioning to successor models, particularly regarding pin configuration and electrical specifications to maintain system integrity without redesigning the host board.

Part Context

The 7133SA series represents Renesas' high-performance dual-port SRAM family, widely utilized in applications demanding concurrent data access. This specific variant belongs to the SA sub-series characterized by 5V operation and standard commercial temperature ratings. The TQFP packaging facilitates automated assembly processes while maintaining signal integrity for high-frequency digital interfaces common in legacy and specialized electronic systems.
