71321SA45J

Memory IC Overview

The 71321SA45J is a high-speed 2K x 8 dual-port static RAM with internal interrupt logic for interprocessor communications. It operates within a supply voltage range of 4.5 V to 5.5 V and features an access time of 45 ns. The device utilizes a parallel interface and is housed in a 52-PLCC package. It supports surface mount installation and functions within an operating temperature range of 0°C to +70°C.

Memory IC Feature Summary

Dual-port architecture enabling simultaneous independent access by two processors
Integrated interrupt logic designed for efficient interprocessor communication
Automatic power down mode controlled by chip enable signals

Memory IC Applications

Stand-alone 8-bit dual-port RAM systems
Master dual-port RAM configurations paired with slave devices
Interprocessor communication interfaces requiring full-speed error-free operation

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part is discontinued. Confirm RoHS compliance status, which may be non-compliant depending on the manufacturing date. Check moisture sensitivity level requirements during storage and handling. Validate pin compatibility if replacing legacy IDT versions. Ensure lead-free specifications match current assembly processes.

Memory IC Selection Notes

Select this component when dual-port memory with integrated interrupts is required for 8-bit systems. Consider the 45 ns access speed for synchronous-like performance without clocking. Evaluate the PLCC-52 package constraints for PCB layout. Compare against single-port alternatives if only one processor accesses the memory. Assess power consumption needs given the automatic power-down feature capabilities.

Memory IC Part Context

This device belongs to the 71321/71421 series of dual-port SRAMs. It serves as a master component that can operate independently or alongside 71421 slave devices to create wider data bus systems. The series emphasizes seamless integration without additional discrete logic for arbitration.
