71V3577S75PFG8

Overview

The Renesas Electronics Corporation 71V3577S75PFG8 is a synchronous static random-access memory (SRAM) device organized as 128K x 36, providing a total storage capacity of 4.5 Mbit. It operates with a maximum clock frequency of 117 MHz and features an access time of 7.5 ns. The component utilizes a parallel interface and requires a core power supply voltage ranging from 3.135 V to 3.465 V. It is housed in a 100-pin TQFP package suitable for surface mount technology. The device supports single data rate (SDR) operation and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Supports high-speed synchronous burst operations with flow-through output mode for efficient data transfer.
• Features self-timed write cycles controlled by global write control and byte write enable signals.
• Includes optional boundary scan JTAG interface compliant with IEEE 1149.1 standards.

Applications

• High-performance computing systems requiring fast data buffering
• Network infrastructure equipment utilizing parallel memory interfaces
• Industrial automation controllers needing reliable synchronous RAM

Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as historical records indicate variations across the 71V3577 series. Check for end-of-life notices or production change notifications that may affect long-term availability. Ensure the source document explicitly lists this exact part number to avoid confusion with similar variants like the BGA packages.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required for system architecture compatibility. The 7.5 ns access time suits applications demanding high throughput at 117 MHz. Consider the 100-pin TQFP package constraints regarding board space and thermal dissipation. Verify that the 3.3V I/O levels match the host processor's voltage requirements without additional level shifting.
