7133SA35PFG8

Memory IC Overview

The 7133SA35PFG8 is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features asynchronous parallel interface operation with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and is housed in a 100-pin Thin Quad Flat Package (TQFP). The component supports surface mount installation and is designed for commercial temperature ranges.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Parallel data interface supporting standard high-speed digital communication protocols

Memory IC Applications

• High-performance embedded systems requiring concurrent data access
• Industrial automation controllers needing reliable volatile memory storage
• Telecommunications equipment utilizing dual-processor architectures

Memory IC Procurement Notes

This component has been officially declared End-of-Life (EOL) by the manufacturer. Production ceased on January 3, 2024, according to Product Change Notices. Current availability is restricted to remaining stock from authorized distributors. Verification of authenticity and lot traceability is critical due to the discontinued status. Buyers should confirm the specific package variant and RoHS compliance level before acquisition.

Memory IC Selection Notes

Engineers replacing this part must account for its discontinuation and select an equivalent dual-port SRAM with matching 32Kb capacity and 35ns speed. The replacement must support the same 4.5V to 5.5V operating voltage and utilize a compatible 100-pin TQFP footprint. Verify that the substitute device maintains asynchronous dual-port functionality and meets the required industrial temperature specifications for the target application environment.

Memory IC Part Context

The 7133SA series belongs to Renesas' legacy line of high-speed dual-port SRAMs, originally developed under IDT branding. These devices were widely used in networking and computing applications requiring low-latency shared memory. The SA suffix typically denotes specific speed grades and package configurations within the broader family, distinguishing it from single-port or synchronous variants.
