Memory IC Overview

The Renesas 71321SA55TFI is a high-speed, 16Kbit (2K x 8) dual-port static random access memory (SRAM). It features asynchronous parallel interfaces for both ports, enabling independent and simultaneous read/write operations. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum access time of 55ns. It is housed in a 64-lead Thin Quad Flat Package (TQFP) with dimensions of 10x10mm. The component includes internal interrupt logic designed to facilitate efficient interprocessor communications without requiring additional discrete logic components.

Memory IC Feature Summary

Dual-port architecture allowing independent operation of two distinct memory ports
Integrated interrupt logic for streamlined interprocessor communication
Automatic power-down mode controlled by chip enable signals
Asynchronous interface supporting flexible system timing

Memory IC Applications

Interprocessor communication in embedded systems
Master dual-port RAM configurations in 16-bit or wider data bus architectures
High-speed buffer memory in standalone microcontroller applications

Memory IC Procurement Notes

Verify the specific suffix requirements for this part number against official Renesas documentation. Confirm lead-free status and moisture sensitivity levels prior to procurement. Ensure compatibility with existing PCB footprints and voltage levels. Check for end-of-life notices or recommended replacement parts if current stock is unavailable.

Memory IC Selection Notes

Select this component when independent dual-port access is required for processor-to-processor data exchange. It is suitable for designs needing 16Kbit capacity with 8-bit word width. Consider the 55ns access speed and TQFP package constraints during layout. Verify that the system voltage aligns with the 4.5V to 5.5V operating range.

Memory IC Part Context

This device belongs to the Renesas 71321 series of dual-port SRAMs. It is often paired with the 71421 slave device to create wider memory systems. The series is characterized by its ability to handle full-speed, error-free operations in complex digital signal processing and control applications.
