71V35761S183PFGI

Overview

The 71V35761S183PFGI is a synchronous static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 4 Mbit organized as 128K x 36 bits. The device supports a maximum clock frequency of 183 MHz with an access time of 3.3 ns. It operates on a parallel interface with a supply voltage range of 3.135 V to 3.465 V and a maximum power current of 350 mA. The component is designed for surface mount installation in a TQFP-100 package, functioning within a temperature range of -40°C to +85°C.

Feature Summary

• Supports pipelined burst operations for high-speed data transfer
• Utilizes single data rate (SDR) synchronous architecture
• Features low-voltage 3.3V core operation

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment
• Industrial control applications

Procurement Notes

Verify the end-of-life status before procurement, as this component is marked as obsolete and will be discontinued by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers, as standard stock may be limited. Ensure that the specific suffix PFGI matches the required package and temperature grade for your design implementation.

Selection Notes

Select this part when a 128K x 36 organization is required for wide-data bus applications. The 183 MHz speed class offers faster performance than lower-frequency variants in the same family. Consider the TQFP-100 package constraints for PCB layout. Verify compatibility with 3.3V logic levels and ensure thermal management meets the specified operating temperature range.

Part Context

This component belongs to the 71V35761S series of synchronous SRAMs from Renesas. It shares architectural similarities with other devices in the family but is distinguished by its specific speed grade and 36-bit data width. The series is designed for applications demanding high bandwidth and low latency memory solutions.

Replacement Considerations

Check for direct pin-to-pin replacements within the 71V35761S series with different speed grades. Evaluate alternative manufacturers offering similar 128K x 36 synchronous SRAMs if sourcing becomes difficult due to obsolescence.
