71V67603S150BQ

Overview

The 71V67603S150BQ is a synchronous single data rate static random access memory integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 9 megabits, organized as 256 kilowords by 36 bits. The device supports a maximum clock frequency of 150 MHz with an access time of 3.8 nanoseconds. It operates within a supply voltage range of 3.135 volts to 3.465 volts and utilizes a parallel interface. The component is housed in a 165-contact CABGA package measuring 13 by 15 millimeters.

Feature Summary

• Supports high-speed parallel data transfer via a synchronous single data rate interface architecture.
• Integrates a large memory organization of 256K x 36 bits for complex data buffering requirements.
• Operates reliably within standard industrial temperature ranges for embedded applications.

Applications

• High-performance networking equipment requiring fast data caching
• Industrial automation systems needing reliable volatile memory
• Telecommunications infrastructure utilizing parallel bus architectures

Procurement Notes

Verify component authenticity through authorized channels due to the obsolete status indicated in public records. Confirm lead times and availability with distributors as stock levels fluctuate. Ensure compliance with RoHS directives if required by specific project standards, noting that this variant may not meet current environmental regulations. Validate package dimensions against PCB footprints prior to procurement.

Selection Notes

Select this component when a 9-megabit synchronous SRAM with a 36-bit word width is required. The 150 MHz speed grade suits applications demanding low latency parallel access. Consider the 165-CABGA package constraints during layout. Evaluate alternatives if lead-free compliance or active production status is mandatory for long-term manufacturing.

Part Context

This part belongs to the 71V67603 series of synchronous SRAMs from Renesas. The series offers various speed grades and packaging options to accommodate different system performance needs. The 71V67603S150BQ specifically targets designs requiring the 150 MHz operational frequency within the CABGA form factor.

Replacement Considerations

Public records list the 71V67703S85BQI as a similar replacement option from Renesas. Verify electrical compatibility and pinout alignment before substitution. Other manufacturers may offer equivalent specifications but require separate validation.
