Memory IC Overview

The 71321SA55PF8 is a high-speed 16Kb (2K x 8) dual-port static RAM manufactured by Renesas Electronics Corporation. It features asynchronous parallel interface with 55 ns access time and write cycle time. The device operates on a single 5V ±10% power supply within a voltage range of 4.5V to 5.5V. It is housed in a 64-pin TQFP package measuring 14x14 mm. The component supports industrial temperature ranges from -40°C to +85°C and includes internal interrupt logic for interprocessor communications.

Memory IC Feature Summary

True dual-ported memory cells enabling simultaneous access to the same memory location without conflict
Integrated internal interrupt flags facilitating direct port-to-port communication between processors
On-chip arbitration logic with BUSY output flag to manage concurrent access requests
Automatic power-down feature controlled by chip enable signals for low standby power consumption

Memory IC Applications

Interprocessor communication in multi-core or multi-processor systems
Master dual-port RAM configuration expanding data bus width using slave devices
Battery backup operation requiring 2V data retention capabilities
High-speed buffer applications requiring full-speed error-free operation

Memory IC Procurement Notes

Verify RoHS compliance status as the component may not meet current environmental regulations. Confirm package dimensions and pinout compatibility during integration. Check for obsolescence notices and lead times for replacement parts. Ensure voltage levels match system requirements strictly within specified limits.

Memory IC Selection Notes

Select this component when true dual-port access and internal interrupt logic are required. Consider the 64-TQFP package for surface mount applications. Evaluate thermal performance within the specified operating temperature range. Compare against newer generation parts if higher speed or lower power is needed.

Memory IC Part Context

This part belongs to the 71321SA/LA series of dual-port SRAMs designed for stand-alone or master-slave configurations. It is intended for systems needing fast, reliable data exchange between independent processors without external arbitration logic.
