Overview
The 71V3558SA166BQGI8 is a synchronous Single Data Rate Zero Bus Turnaround SRAM manufactured by Renesas Electronics. It provides a total storage capacity of 4.5 Mbit organized as 256K words by 18 bits. The device supports a maximum clock frequency of 166 MHz with a typical access time of 3.5 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and features a parallel interface. The component is housed in a 165-CABGA package measuring 13x15 mm, designed for surface mount installation.
Feature Summary
- Supports high-speed synchronous data transfer with burst counter pipelined outputs
- Utilizes Zero Bus Turnaround technology to minimize bus turnaround cycles
- Features 3.3V I/O compatibility for system integration
Applications
- High-performance embedded systems requiring fast random access memory
- Industrial equipment control units
- Telecommunications infrastructure hardware
Procurement Notes
Verify current availability status as the component may be subject to discontinuation notices. Confirm that the specific suffix matches the required packaging type and temperature grade. Check for official Product Change Notices regarding label changes or manufacturing site updates before finalizing procurement plans.
Selection Notes
Select this part when a 256K x 18 organization is required for wide data paths. Ensure the design accommodates the 165-CABGA footprint and thermal requirements. Verify that the system clock does not exceed the 166 MHz limit and that power supply noise remains within the specified voltage tolerance for reliable operation.
Part Context
This component belongs to the 71V3558 series of synchronous ZBT SRAMs from Renesas. It shares architectural similarities with other variants in the family but differs in speed grade and organizational structure. The series is designed for applications demanding low latency and high throughput in compact surface-mount packages.
Replacement Considerations
Direct substitutes include IDT71V3558SA166BQG8 and 71V3558SA166BQG. Verify pinout compatibility and electrical specifications before substitution.
