71321LA45JI8

Memory IC Overview

The Renesas Electronics Corporation 71321LA45JI8 is a high-speed static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The device supports an access time of 45 ns and operates within a supply voltage range of 4.5 V to 5.5 V. Maximum power supply current is specified at 140 mA. It is designed for surface mount installation in a PLCC-52 package. The component functions within a commercial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Provides high-speed asynchronous data access with a 45 ns cycle time for rapid read operations.
• Utilizes a 52-pin Plastic Leadless Chip Carrier (PLCC) surface-mount package for compact board integration.
• Operates on a standard 5V power supply, ensuring compatibility with conventional logic families.

Memory IC Applications

• High-speed data buffering in industrial control systems
• Cache memory implementation in embedded processing units
• Data storage in telecommunications equipment

Memory IC Procurement Notes

Verify the specific suffix 'JI8' against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the 71321 series. Confirm RoHS compliance status, as older SRAM variants may not meet current environmental standards. Check for obsolescence notices, as this component type may be subject to discontinuation or lifecycle changes. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Memory IC Selection Notes

Select this component when a 16 kbit SRAM with 45 ns access speed is required in a PLCC-52 package. It is suitable for designs needing 5V operation and commercial temperature range performance. Compare against the 71321LA55 variant if slower access times are acceptable for lower power consumption. Ensure the target system interface matches the parallel architecture of this device.

Memory IC Part Context

This part belongs to the Renesas 71321LA series of high-speed SRAMs. These devices are designed for applications requiring fast, non-volatile-like data retention during power cycles, though they are volatile memory. The series typically offers various access speeds and packaging options to suit different design constraints in computing and communication hardware.

Memory IC Replacement Considerations

Direct substitutes include other 16 kbit (2Kx8) SRAMs in PLCC-52 packages with 45 ns access times. Verify pin compatibility and voltage levels before swapping. Cross-reference with IDT or Cypress equivalents if available, ensuring functional parity in timing and organization.
