71V65603S133PFG8

Overview

The 71V65603S133PFG8 is a synchronous ZBT SRAM with 9 Mbit capacity organized as 256K x 36. It operates at a maximum clock frequency of 133 MHz with a 4.2 ns access time. The device uses a 100-TQFP (14x14) package and supports parallel interface. Supply voltage ranges from 3.135 V to 3.465 V, with a maximum supply current of 300 mA. Operating temperature spans -40°C to +85°C. Moisture sensitivity level is MSL 3.

Feature Summary

• Supports synchronous single data rate burst operations with pipelined outputs
• Features low power consumption for high-density memory applications
• Includes on-chip burst counter for simplified interface control

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory in network processing systems
• Frame buffer storage in video processing units

Procurement Notes

Verify RoHS compliance status as the PFG8 suffix may indicate non-compliant variants compared to standard PFG versions. Confirm lead times due to potential end-of-life transitions within the 71V65603 family. Check moisture sensitivity handling requirements before assembly. Validate pin compatibility with existing PCB footprints for the 100-TQFP package.

Selection Notes

Select this component when 256K x 36 organization is required for wide data paths. Choose over narrower widths to reduce chip count in parallel bus architectures. Ensure system timing allows for 4.2 ns access at 133 MHz. Consider thermal management for 300 mA peak current draw in enclosed designs.

Part Context
