7026L15JG

Memory IC Overview

The 7026L15JG is a dual-port static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 256 kilobits organized as 16K words by 16 bits. The device operates with asynchronous parallel interfaces and supports a supply voltage range from 4.5V to 5.5V. Access time is specified at 15 nanoseconds, with an identical write cycle time. It functions within a commercial temperature range of 0°C to 70°C and is housed in an 84-pin Plastic Leadless Chip Carrier package measuring 29.31mm by 29.31mm.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from both ports
• Includes on-chip hardware semaphore signaling for port arbitration
• Features separate upper-byte and lower-byte control signals
• Provides automatic power-down functionality via chip enable control

Memory IC Applications

• Stand-alone dual-port memory systems
• Master/Slave configurations for 32-bit or wider data bus expansion
• High-speed data buffering applications requiring concurrent read/write operations

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance specifications against current manufacturing records. Validate package dimensions and pinout compatibility before integration into existing designs. Check for available replacement alternatives if long-term supply stability is required.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is necessary without external arbitration logic. Ensure system requirements align with the 5V TTL-compatible interface standards. Verify that the 84-PLCC package fits the target PCB layout constraints. Consider thermal management capabilities within the specified commercial operating temperature range.

Memory IC Part Context

This part belongs to the 7026L series of high-speed dual-port SRAMs designed for complex digital signal processing and communication systems. The series emphasizes low standby power consumption and full asynchronous operation. It serves as a critical interconnect element between processors requiring shared memory resources.
