71V546S100PFG

Overview

The 71V546S100PFG is a static random access memory component manufactured by Renesas Electronics Corporation. It features a storage capacity of 4 Mbit, organized as 128 k x 36. The device supports a maximum clock frequency of 100 MHz with an access time of 10 ns. It operates on a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. The maximum power consumption current is 200 mA. The unit is housed in a TQFP-100 surface-mount package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Supports synchronous single data rate (SDR) operations for high-speed data transfer
• Utilizes zero-bus-turnaround (ZBT) technology to eliminate dead bus cycles during read/write transitions
• Provides pipelined architecture for improved throughput efficiency

Applications

• High-performance embedded systems requiring fast memory access
• Industrial equipment control units
• Network infrastructure hardware
• Telecommunications signal processing modules

Procurement Notes

Verify the specific suffix 'G' against official Renesas documentation to confirm packaging details, as distributor listings may vary regarding tray versus reel configurations. Confirm that the commercial temperature range meets system requirements. Check for end-of-life notices or production change notifications prior to finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when a 128k x 36 organization is required for wide-data applications. Ensure the design accommodates the 3.3V core voltage and 100 MHz clock speed. Verify that the TQFP-100 footprint fits the PCB layout constraints. Consider thermal management capabilities given the 200 mA maximum current draw at peak operation speeds.

Part Context

This part belongs to the 71V546 series of synchronous SRAMs from Renesas. It shares architectural similarities with other ZBT devices in the lineup but differs in density and pinout configuration. The series is designed for applications demanding low latency and high bandwidth without the complexity of burst-mode controllers.

Replacement Considerations

The 71V547S100PFGI8 is listed as a similar alternative. Verify pin compatibility and electrical specifications before substitution.
