71V3577S75BGI

Overview

The Renesas Electronics Corporation 71V3577S75BGI 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 a typical access time of 7.5 ns. The component utilizes a parallel interface and requires a core supply voltage ranging from 3.135 V to 3.465 V. It is housed in a 119-pin plastic ball grid array (PBGA) package measuring 14x22 mm. The device supports single data rate (SDR) operation and is designed for surface mount installation.

Feature Summary

• Supports high-speed synchronous burst operations with flow-through architecture for efficient data throughput.
• Integrates self-timed write cycles controlled by global write control and byte write enable signals.
• Includes low battery detect input to manage power-down states and preserve data integrity.

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial equipment with real-time processing demands
• Network infrastructure components needing reliable volatile memory

Procurement Notes

Verify the specific suffix BGI against official datasheets to confirm the 119-PBGA package and commercial temperature range. Confirm RoHS compliance status as historical records indicate potential non-compliance for older batches. Check for End-of-Life notifications or discontinuance notices prior to finalizing procurement plans.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required for system integration. Ensure the design accommodates the 119-pin PBGA footprint and thermal requirements. Verify that the 3.3V I/O levels match the host processor specifications. Consider alternative packages if board space constraints differ from the 14x22 mm form factor.
