7025S12J8

Memory IC Overview

The Renesas Electronics Corporation 7025S12J8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features a parallel interface with a maximum access time of 12 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two distinct ports for high-throughput data handling.
• Utilizes asynchronous logic control without requiring a system clock signal for operation.
• Provides non-volatile-free volatile storage suitable for temporary data buffering and caching tasks.

Memory IC Applications

• Digital Signal Processor (DSP) controller systems
• Real-time motor control applications
• High-speed data buffering interfaces

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Review official documentation for end-of-life status or lifecycle notices to ensure long-term project viability and compliance with current manufacturing standards.

Memory IC Selection Notes

Select this component when dual-port architecture is required for concurrent processor access. Ensure the design accommodates the 68-PLCC footprint and 4.5V to 5.5V power supply rails. Validate that the 12ns access speed meets the timing constraints of the target application bus interface.

Memory IC Part Context

This part belongs to the Renesas 7025S series of asynchronous dual-port SRAMs. It shares architectural similarities with other members like the 7025S35J8 and 7025S55JG8, differing primarily in access speed and pin configuration. The series targets embedded systems requiring fast, independent memory access capabilities.
