71V35761S183PFGI

Memory IC Overview

The IDT71V35761S183PFGI is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Integrated Device Technology, now part of Renesas Electronics. It features a total storage capacity of 4.5 megabits, organized as 128K words by 36 bits. The device supports parallel interface operations with a maximum clock frequency of 183 MHz and an access time of 3.3 nanoseconds. It operates within a supply voltage range of 3.135V to 3.465V and is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. The component is designed for surface-mount installation and functions across an industrial temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Supports high-speed synchronous single data rate (SDR) operations with pipelined outputs for efficient data throughput.
• Integrates a burst counter mechanism to manage sequential memory access patterns automatically.
• Enables single-cycle deselect capability, allowing immediate termination of current burst transfers without waiting for completion.

Memory IC Applications

• Memory buffering in embedded systems requiring fast data staging.
• High-performance networking equipment utilizing parallel SRAM interfaces.
• Industrial control systems operating within extended temperature ranges.

Memory IC Procurement Notes

Verify the manufacturer status, as IDT has been acquired by Renesas Electronics Corporation. Confirm that the specific package variant matches the required 100-TQFP form factor. Check for RoHS compliance status, as older production runs may not meet current environmental regulations. Ensure the lead time aligns with project schedules given potential end-of-life considerations for legacy components.

Memory IC Selection Notes

Select this component when a 4.5Mb capacity with 36-bit word width is required for parallel data paths. The 183 MHz speed rating suits applications needing low-latency access under 3.3ns. Consider the 100-TQFP package if board space constraints favor surface-mount technology over BGA options. Validate power supply stability within the 3.135V to 3.465V range to ensure reliable synchronous operation.

Memory IC Part Context

This device belongs to the 71V35761S series of 3.3V Synchronous SRAMs. The '183' suffix denotes the 183 MHz speed grade, while 'PFGI' specifies the 100-TQFP package type with industrial temperature rating. Similar variants exist in BGA packages, such as the 71V35761S183BQI8, offering different footprint solutions for the same core functionality.

Memory IC Replacement Considerations

Direct substitutes include other 71V35761S variants with compatible pinouts, such as the 71V35761S183BG8 in a BGA package, provided mechanical constraints allow. Verify electrical compatibility regarding voltage levels and timing parameters before substitution.
