71V321LA55PF8

Overview

The 71V321LA55PF8 is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface mount installation in a 64-pin Thin Quad Flat Package measuring 14x14 millimeters. The component is rated for an ambient operating temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Applications

• Data buffering in high-speed digital systems.

Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm that the 4.5V to 5.5V supply requirement aligns with the target system design. Check current manufacturing status as this part may be discontinued or subject to last-time buy notices. Ensure environmental compliance requirements are met if RoHS certification is mandatory for the application.

Selection Notes

Select this component when a 16Kb dual-port SRAM with 55ns access speed is required. Ensure the system voltage supports the 4.5V minimum threshold. Verify that the 64-TQFP package fits the available PCB footprint. Consider thermal management capabilities within the 0°C to 70°C operating range.

Part Context

This part belongs to the 71V321LA series of dual-port SRAMs from Renesas. It shares architectural similarities with other members of the family but differs in access speed and voltage specifications. The LA designation typically indicates specific performance characteristics distinct from other variants like the L25 series.
