71V546S100PFGI8

Overview

The 71V546S100PFGI8 is a 4.5 Mbit synchronous static random access memory (SRAM) organized as 128K x 36 bits. It operates with a maximum clock frequency of 100 MHz and features a 5 ns access time. The device utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. It is housed in a 100-TQFP package measuring 14x20 mm, designed for surface mount installation. The component supports single data rate (SDR) operations within an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports high-speed synchronous data transfer at up to 100 MHz
• Provides fast 5 ns access time for low-latency memory operations
• Features ZBT technology to eliminate dead bus cycles during read/write transitions

Applications

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

Procurement Notes

Verify the current manufacturing status before procurement, as this specific part number may be obsolete or discontinued. Confirm availability of qualified replacement components such as the 71V547S100PFGI8 if sourcing new inventory is not possible. Ensure that any substitute parts meet the required electrical specifications and physical footprint constraints for your design.

Selection Notes
