71V2556S133PFGI8

Overview

The 71V2556S133PFGI8 is a synchronous Single Data Rate (SDR) Static Random Access Memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage capacity of 9 Mbit, organized as 256K x 36 bits. The device operates with a maximum clock frequency of 133 MHz and an access time of 4.2 ns. It utilizes a parallel interface and is housed in a 100-TQFP package measuring 14x14 mm. The component supports a supply voltage range of 3.135 V to 3.465 V and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead bus cycles during read-to-write or write-to-read transitions.
• Synchronous pipelined operation provides four cycles of data for a single address presented to the SRAM.
• Integrated registers for data I/O, address, and control signals enhance system performance.

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment
• Industrial automation controllers

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures before assembly. Check for specific revision markings on the datasheet release date to ensure compatibility with current design requirements.

Selection Notes

Select this part for applications needing high-speed synchronous memory with wide data buses. Ensure voltage levels match the 3.3V core and 2.5V I/O specifications if applicable. Consider thermal management for the TQFP package in enclosed environments.
