7006S12J

Overview

The Renesas Electronics Corporation 7006S12J is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kilobits, organized as 16K 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 4.5V to 5.5V and supports surface-mount installation in a 68-PLCC package measuring 24.21x24.21 mm. The component is designed for commercial temperature applications ranging from 0°C to 70°C.

Feature Summary

• Supports simultaneous independent read/write operations at two distinct ports
• Provides high-speed data access through asynchronous parallel interface
• Utilizes CMOS technology for low power consumption and reliable performance

Applications

• High-performance embedded systems requiring fast local memory
• Industrial control units needing reliable volatile storage
• Telecommunications equipment buffer memory
• Network infrastructure hardware caching

Procurement Notes

Verify the specific suffix J against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as historical data indicates potential non-compliance for older batches. Check current product lifecycle status, as this model may be discontinued or subject to last-time buy restrictions. Ensure supplier sources authentic components to avoid counterfeit risks associated with legacy memory parts.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access without external arbitration logic. Compare the 12 ns access speed against system clock requirements to ensure timing margins are met. Evaluate the 68-PLCC footprint against available PCB real estate and assembly capabilities. Consider thermal management needs within the specified commercial temperature range during design integration.

Part Context

This part belongs to the Renesas 7006 series of dual-port SRAMs, which are widely used in applications requiring shared memory access between multiple masters. The series offers various speed grades and packaging options to suit different performance and form factor constraints. The 7006S12J represents a specific speed bin within this established family of asynchronous memory solutions.

Replacement Considerations

Official substitutes include other variants within the 7006S series such as the 7006S15J or 7006S20J, provided slower speeds are acceptable. Verify pin-to-pin compatibility and electrical specifications before substitution. Cross-reference with IDT-branded equivalents if sourcing from distributors using legacy naming conventions.
