7037L20PFI

Memory IC Overview

The Renesas Electronics Corporation 7037L20PFI is a high-speed asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 576 kbit, organized as 32k words by 18 bits. The component features a parallel interface with a maximum access time of 20 ns. It operates on a single 5V power supply, with voltage specifications ranging from 4.5 V to 5.5 V. The device is housed in a 100-pin Thin Quad Flat Package (TQFP) suitable for surface-mount technology. It supports an industrial operating temperature range from -40°C to +85°C and includes humidity sensitivity classification.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent read and write operations from either port without bus contention.
• On-chip hardware support for semaphore signaling and interrupt flags to facilitate efficient data synchronization between processors.
• Automatic power-down functionality controlled by chip enable signals to minimize standby power consumption during idle periods.

Memory IC Applications

• Multiprocessor systems requiring shared memory resources with low-latency access.
• Industrial control networks utilizing master/slave configurations for expanded word widths.
• Telecommunications equipment needing reliable high-speed data buffering.

Memory IC Procurement Notes

Verify the specific suffix PFI against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as legacy components may vary. Check current lifecycle status, as this part number may be discontinued or subject to last-time buy restrictions. Ensure ESD handling protocols are followed due to moisture sensitivity level requirements during assembly.

Memory IC Selection Notes

Select this component when a 5V logic interface is required for dual-port memory applications. Compare against the 70V37L series if 3.3V operation is necessary instead of 5V. Consider the 7037L20PF variant if tray packaging is preferred over tape and reel. Evaluate thermal management needs within the specified industrial temperature range for long-term reliability.

Memory IC Part Context

This device belongs to the Renesas 7037L family of dual-port SRAMs. It serves as a standalone memory solution or can be cascaded in master/slave modes to create wider memory architectures. The family is designed for applications demanding high-speed data exchange between multiple processors or controllers in embedded systems.
