71V65603S150PFG8

Overview

The 71V65603S150PFG8 is a synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 9 Megabits, organized as 256K words by 36 bits. The device supports a maximum clock frequency of 150 MHz with an access time of 6.7 ns. It operates on a single 3.3V power supply within the range of 3.135V to 3.465V and features a parallel interface. The component is housed in a 165-pin Ceramic Ball Grid Array (CABGA) package measuring 13x15 mm. It is designed for surface mount installation and is currently listed as an active product.

Feature Summary

• Supports high-speed data transfer via a parallel interface synchronized with a clock signal up to 150 MHz.
• Utilizes Zero Bus Turnaround (ZBT) technology to eliminate wait states during bus direction changes.
• Provides wide data width capability through a 36-bit word organization structure.

Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications infrastructure systems
• Industrial control systems with strict timing requirements

Procurement Notes

Verify the specific suffix PFG8 indicates the Tape & Reel packaging configuration, distinct from tray-packaged variants like PFGI or BQ. Confirm RoHS compliance status for the specific reel batch, as earlier versions of this family may have different environmental certifications. Ensure the CABGA-165 footprint matches the target PCB design, noting the 13x15 mm dimensions. Check for any recent Product Change Notifications regarding assembly sites or material updates.

Selection Notes

Select this component when a 36-bit data path is required for memory applications. The 150 MHz speed grade offers faster performance than the 100 MHz variant while maintaining ZBT efficiency. Consider the 165-pin CABGA package for high-density board layouts where pin count exceeds TQFP capabilities. Evaluate thermal dissipation requirements for the ceramic package in enclosed industrial environments.

Part Context

This part belongs to the 71V65603 series of synchronous SRAMs. It shares the same core memory architecture and electrical specifications as other suffixes such as 71V65603S150BQ and 71V65603S150PFGI. The primary distinction lies in the physical packaging and shipping format. The series is widely used in embedded systems requiring non-volatile-like speed without the complexity of flash memory controllers.

Replacement Considerations

IS61NLP25636A-200TQLI by Integrated Silicon Solution Inc is documented as a similar alternative. Verify pin compatibility and voltage levels before substitution. Other Renesas variants like 71V65603S133PFGI offer lower speeds but may fit if timing margins allow.
