71V321L25PFI

Overview

The Renesas Electronics Corporation 71V321L25PFI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The device supports asynchronous parallel interface operations with a maximum access time of 25 ns. It operates within a supply voltage range of 3 V to 3.6 V and has a maximum power supply current of 100 mA. The component is housed in a 64-pin TQFP package measuring 14x14 mm. It is designed for industrial temperature ranges, functioning between -40°C and +85°C.

Feature Summary

• Provides independent read/write ports for simultaneous data access by two masters.
• Supports asynchronous operation without requiring an external clock signal.
• Utilizes CMOS technology for low power consumption during standby and active modes.

Applications

• Data buffering in high-speed communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications in digital signal processing

Procurement Notes

Verify the specific suffix configuration against the latest manufacturer datasheet to ensure compatibility with required packaging and environmental standards. Confirm RoHS compliance status as historical records indicate potential variations. Check for obsolescence notices or production change notifications prior to finalizing procurement plans to mitigate supply chain risks associated with end-of-life components.

Selection Notes

Select this component when independent dual-port functionality is required for concurrent master access. Ensure the design accommodates the 64-TQFP footprint and thermal requirements for the specified operating temperature range. Verify that the 3.3 V logic levels align with the system's I/O voltage specifications. Consider alternative packages if surface-mount density constraints differ from the standard tray or reel options available.
