71V65803S133PFGI

Overview

The IDT71V65803S133PFGI is a 9Mb (512K x 18) synchronous ZBT SRAM manufactured by Renesas Electronics Corporation. It operates at a clock frequency of 133 MHz with a maximum access time of 4.2 ns. The device utilizes a parallel interface and requires a supply voltage between 3.135V and 3.465V. It is housed in a 100-TQFP (14x14) surface-mount package and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Supports high-performance system speeds through synchronous operation without dead cycles between write and read operations.
• Features internally synchronized output buffer enable, eliminating the need for external control of the OE pin.
• Utilizes a single R/W control pin to simplify interface logic.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory applications in embedded systems
• Network switching and routing hardware

Procurement Notes

Verify the manufacturer designation as Renesas Electronics Corporation on official datasheets, as IDT was acquired. Confirm the specific suffix PFGI corresponds to the 100-TQFP package and industrial temperature grade. Ensure compatibility with 3.3V I/O levels and check for RoHS3 compliance status in current production notices.

Selection Notes

Select this component when a 512K x 18 configuration is required for synchronous burst operations. It is suitable for designs needing 133 MHz performance with low latency. Consider the 100-pin TQFP footprint for PCB layout constraints. Verify power supply stability within the specified 3.135V to 3.465V range for reliable operation.

Part Context

This part belongs to the 71V65803 family of 3.3V Synchronous ZBT SRAMs. It shares architectural similarities with other variants like the 71V65803S100PFG8 but offers higher speed performance. The family is characterized by its pipelined outputs and byte-write capabilities, designed for complex digital signal processing tasks.
