71V3558SA133BQG8

Overview

The 71V3558SA133BQG8 is a synchronous single data rate zero bus turnaround SRAM manufactured by Renesas Electronics. It features a storage capacity of 4.5 Mbit organized as 256K x 18. The device operates with a maximum clock frequency of 133 MHz and an access time of 4.2 ns. It supports parallel interface communication and requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a 165-CABGA package measuring 13x15 mm and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Synchronous SDR ZBT architecture enabling high-speed data transfer without wait states
• Pipelined output structure designed for efficient burst data handling
• Integrated burst counter for automated sequential memory access operations

Applications

• High-performance embedded systems requiring fast local memory
• Network infrastructure equipment demanding low-latency data buffering
• Industrial control units operating in extended temperature environments

Procurement Notes

Verify the specific suffix BQG8 against official Renesas documentation to confirm the exact package type and temperature grade. Confirm RoHS3 compliance status through current datasheets. Check for End-of-Life notices or Product Change Notifications regarding assembly site changes or labeling updates before finalizing procurement plans.

Selection Notes

Select this component when a 256K x 18 organization is required rather than the 128K x 36 variant found in the 71V3556 series. Ensure the design accommodates the 165-pin CABGA footprint and thermal requirements for the industrial temperature range. Validate that the system power supply strictly maintains the 3.3V I/O tolerance limits specified for reliable operation.

Part Context

This part belongs to the 71V3558 family of synchronous SRAMs, which are optimized for applications needing wide data buses and high throughput. The SA suffix typically denotes the industrial temperature grade and specific package configuration within the broader product line. These devices complement Renesas' portfolio of high-speed memory solutions for complex digital signal processing tasks.
