Overview

The IDT71V3577S80BQI is a 4.5Mb synchronous single data rate (SDR) static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface with a memory organization of 128K x 36 bits. The device supports a maximum clock frequency of 100 MHz and provides an access time of 8 ns. It operates within a supply voltage range of 3.135V to 3.465V and is housed in a 165-pin cavity ball grid array package measuring 13x15 mm. The component is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed synchronous operation with a 100 MHz clock frequency and 8 ns access time.
• Features a 36-bit wide parallel data interface for efficient system integration.
• Includes boundary scan JTAG interface capability compliant with IEEE 1149.1 standards.

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control applications operating within extended temperature ranges

Procurement Notes

Verify the specific suffix BQI to confirm the 165-CABGA package and industrial temperature rating, as other suffixes indicate different packages or grades. Confirm RoHS compliance status, as this specific part number may not meet current environmental regulations. Check for active obsolescence notices from Renesas, as availability is limited. Ensure design-in compatibility with existing PCB footprints for the 165-pin cavity BGA configuration.

Selection Notes

Select this component when a 36-bit data width is required for parallel processing tasks. Consider the 165-pin cavity BGA package for space-constrained designs needing robust surface-mount assembly. Evaluate the 100 MHz speed against system clock requirements to ensure adequate timing margins. Compare against alternative memory densities if 4.5Mb exceeds actual capacity needs.

Part Context

This device belongs to the 71V3577 family of synchronous flowthrough SRAMs. The family offers various speed grades and packaging options, including TQFP and PBGA formats. The 71V3577 series is designed for applications demanding high throughput and low latency, serving as a bridge between slower processors and faster peripheral devices in complex electronic architectures.
