71V65603S133BG8

Overview

The 71V65603S133BG8 is a 9 Mbit synchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It features a parallel interface and operates at a maximum clock frequency of 133 MHz with an access time of 4.2 ns. The device is organized as 512 k x 18 bits and utilizes Single Data Rate (SDR) technology. It functions within a supply voltage range of 3.135 V to 3.465 V, with a maximum power consumption of 260 mA. The component is housed in a PBGA-119 surface-mount package and supports commercial operating temperatures from 0°C to +70°C.

Feature Summary

• Supports high-speed data transfer via a 133 MHz synchronous parallel interface
• Provides fast 4.2 ns access time for low-latency memory operations
• Utilizes ZBT (Zero Bus Turnaround) architecture to eliminate dead bus cycles during read-write transitions

Applications

• High-performance embedded systems requiring rapid data buffering
• Industrial equipment control units needing reliable real-time memory
• Network infrastructure hardware utilizing synchronous SRAM interfaces

Procurement Notes

Verify the specific suffix BG8 against official Renesas documentation to confirm the PBGA-119 package and lead-free status. Confirm current production status as end-of-life notices may apply to this series. Ensure compatibility with 3.3V logic levels and check moisture sensitivity handling requirements before assembly.

Selection Notes

Select this component when a 512k x 18 organization is required for wide-data applications. It is suitable for designs needing 133 MHz throughput without the complexity of pipelined architectures. Consider thermal management for the PBGA package within the specified commercial temperature range.
