71V546S133PFG

Overview

The Renesas Electronics Corporation 71V546S133PFG is a synchronous single data rate (SDR) static random-access memory (SRAM) integrated circuit. It features a storage capacity of 4.5 Mbit organized as 128K x 36 bits. The device supports a maximum clock frequency of 133 MHz with an access time of 4.2 ns. It operates on a supply voltage range of 3.135 V to 3.465 V and functions within a temperature range of 0°C to 70°C. The component is housed in a 100-TQFP (14x14) surface-mount package.

Feature Summary

• Supports high-speed parallel interface operations at frequencies up to 133 MHz
• Provides fast data access with a specified access time of 4.2 ns
• Designed for reliable performance across standard commercial operating temperatures

Applications

• High-performance computing systems requiring fast data buffering

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations may exist. Confirm current manufacturing status, as this specific part number may be discontinued or subject to change. Ensure compatibility with existing system voltage levels and thermal requirements before procurement. Cross-reference with authorized distributors to validate authenticity and availability.

Selection Notes

Select this component when a 4.5 Mbit synchronous SRAM with a 36-bit width is required. It is suitable for designs needing 133 MHz operation speeds and 4.2 ns latency. Ensure the application environment stays within the 0°C to 70°C temperature range. Verify that the 3.3V nominal supply voltage aligns with the system power architecture.

Part Context

This component belongs to the Renesas 71V546 series of synchronous SRAMs. It shares architectural similarities with other parts in the family but differs in speed grade and packaging. The 133 MHz variant offers higher throughput compared to slower versions, making it appropriate for bandwidth-intensive applications requiring rapid data retrieval and storage capabilities.

Replacement Considerations

Official substitutes include IDT71V546S133PF and ISSI IS61NLP12836B-200TQLI. Verify pinout compatibility and electrical specifications before substitution. Check for any differences in moisture sensitivity levels or RoHS compliance status.
