71V3556SA150BQ8

Overview

The 71V3556SA150BQ8 is a synchronous Single Data Rate Zero Bus Turnaround SRAM manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 4.5 Mbit, organized as 128K words by 36 bits. The device operates with a maximum clock frequency of 150 MHz and features a typical access time of 3.8 ns. It utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a 165-CABGA package measuring 13x15 mm and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports high-speed data transfer via a 150 MHz synchronous clock interface
• Utilizes Zero Bus Turnaround technology to minimize bus turnaround latency
• Features pipelined output architecture for efficient burst data handling

Applications

• High-performance networking equipment requiring fast memory buffering
• Telecommunications infrastructure systems
• Industrial control systems with strict timing requirements

Procurement Notes

Verify the specific suffix BQ8 to confirm the 165-CABGA package type and commercial temperature range. Confirm RoHS compliance status as sources indicate non-compliance. Check for End-of-Life notices, as this product family has been subject to discontinuation announcements. Ensure the supplier provides valid traceability documentation for legacy components.

Selection Notes

Select this model when a 36-bit wide data path is required for system integration. Compare against the 71V3556SA100BQ8 if lower power consumption or cost is prioritized over the 150 MHz speed. Consider the 71V3556SA133BQI8 variant if industrial temperature ratings are necessary instead of commercial limits.

Part Context

This part belongs to the IDT 71V3556/58 series of 3.3V Synchronous ZBT SRAMs. The 'SA' designation typically indicates the specific speed grade and package configuration within the broader product line. These devices are designed to replace older asynchronous SRAMs in high-speed digital signal processing applications.

Replacement Considerations

Direct pin-to-pin replacements include the 71V3556SA100BQ8 (slower speed) and 71V3556SA133BQ8 (intermediate speed). Verify that the system clock can accommodate the different access times if substituting with slower variants.
