71V3558SA100BQG8

Overview

The 71V3558SA100BQG8 is a 4.5Mb (256K x 18) synchronous ZBT SRAM manufactured by Renesas Electronics Corporation. It operates with a clock frequency of 100 MHz and features a 5 ns access time. The device utilizes a parallel interface and requires a supply voltage between 3.135V and 3.465V. It is housed in a 165-CABGA package measuring 13x15 mm. The component supports surface mount installation and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Synchronous Zero-Bus Turnaround (ZBT) technology for high-speed data transfer
• Pipelined outputs with burst counter functionality
• Parallel memory interface architecture

Applications

• Data communication systems
• Network infrastructure equipment
• Industrial control applications

Procurement Notes

Verify the specific suffix BQG8 against official Renesas documentation to confirm the reel packaging configuration, as standard listings may indicate tray packaging. Confirm RoHS3 compliance status through current datasheets. Check for End-of-Life notices or Product Change Notifications regarding assembly site changes or label updates before procurement.

Selection Notes

Select this component when a 256K x 18 organization is required with 100 MHz synchronous performance. Ensure the design accommodates the 165-CABGA footprint and 3.3V I/O levels. Consider alternative speed grades if higher throughput is needed, or different packages if board space constraints differ from the 13x15 mm requirement.
