71V546S133PFGI

Overview

The 71V546S133PFGI is a synchronous single data rate (SDR) static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 9 Mbit organized as 256K x 36 bits. The device supports a maximum clock frequency of 133 MHz with an access time of 4.2 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and has a maximum power current of 280 mA. The component is housed in a 100-pin TQFP package suitable for surface mount technology and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed parallel interface operation at frequencies up to 133 MHz
• Provides 9 Mbit storage density with a 36-bit data bus width
• Designed for industrial environments with extended temperature range capability

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial equipment control units
• Network infrastructure hardware

Procurement Notes

Verify the specific suffix PFGI against official Renesas documentation to confirm the exact package type and moisture sensitivity level. Confirm RoHS compliance status through the manufacturer's latest product change notices. Ensure that the required operating temperature range aligns with the industrial grade specifications defined in the datasheet before finalizing procurement plans.

Selection Notes

Select this component when a 36-bit wide data path is required for system integration. The synchronous architecture suits designs needing precise clock synchronization. Consider the 100-pin form factor for board space constraints. Verify that the 3.3V logic levels match the host processor interface requirements without additional level shifting components.

Part Context

This part belongs to the 71V67603/71V546 series of synchronous SRAMs from Renesas. These devices are engineered to eliminate dead bus cycles during read-write transitions, enhancing throughput in pipelined architectures. The series offers various speed grades to accommodate different processing demands while maintaining compatibility with standard 3.3V CMOS logic families.

Replacement Considerations

Check for direct pin-compatible upgrades within the same Renesas family. Verify if alternative speed grades meet the timing requirements. Ensure any substitute maintains the 256K x 36 organization and 100-TQFP package dimensions.
