7026L15J

Memory IC Overview

The Renesas Electronics Corporation 7026L15J is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 256 kilobits organized as 16K words by 16 bits. The device operates with an access time of 15 nanoseconds and supports parallel interface communication. It requires a supply voltage ranging from 4.5 volts to 5.5 volts. The component is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package, measuring 29.31mm by 29.31mm. It is designed for surface mount installation and functions within an ambient temperature range of 0°C to 70°C.

Memory IC Procurement Notes

Verify the exact suffix designation on the component marking against official documentation, as variations such as JG may indicate specific packaging or lead finish options. Confirm RoHS compliance status through current manufacturer notices, as older batches may differ. Ensure the procurement channel provides traceability for this discontinued series to maintain quality assurance standards during replacement sourcing.

Memory IC Selection Notes

Select this component when a design requires true dual-port memory architecture allowing concurrent host and peripheral access. The 16-bit word width suits applications needing wide data paths without external multiplexing. Verify that the 5V logic levels match the system voltage requirements. Consider the PLCC package constraints regarding PCB space and thermal management capabilities for the target enclosure environment.

Memory IC Part Context

This part belongs to the Renesas 7026L family of high-performance dual-port SRAMs. These devices are engineered for applications demanding high bandwidth and low latency. The 7026L15 variant specifically targets systems requiring 256Kbit density with 15ns speed grades. It serves as a critical interconnect buffer between processors and peripherals in complex digital architectures.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as the 7026L35J, noting differences in access speed. Evaluate newer generations like the 70V657S12BCGI for potential upgrades, verifying voltage compatibility and package footprint alignment before substitution.
