R1LP0408DSB-5SI#S0

Memory IC Overview

The R1LP0408DSB-5SI#S0 is a 4Mb (512K x 8) static random-access memory (SRAM) manufactured by Renesas Electronics. It operates with a supply voltage range of 4.5V to 5.5V and features an access time of 55ns. The component is housed in a 32-TSOP II surface-mount package. It supports parallel interface communication and functions within an operating temperature range of -40°C to 85°C. The device utilizes SRAM technology for volatile data storage.

Memory IC Feature Summary

• Provides 4Mbit non-volatile storage capacity organized as 512K words by 8 bits
• Supports high-speed parallel data transfer with 55ns access time
• Operates reliably across industrial temperature ranges from -40°C to 85°C

Memory IC Applications

• Industrial control systems requiring fast data buffering
• Embedded applications needing compact volatile memory solutions
• Automotive electronics operating under wide temperature conditions

Memory IC Procurement Notes

Verify the specific suffix #S0 indicates tape-and-reel packaging, distinct from tray options like #B0. Confirm end-of-life status through official Renesas channels, as availability may be restricted. Ensure compatibility with 5V logic levels and TSOP II footprint requirements during integration planning.

Memory IC Selection Notes

Select this part when a 4Mb SRAM with 55ns speed is required in a 32-pin TSOP II package. Compare against other R1LP0408 variants based on packaging preferences (tray vs. reel). Verify voltage tolerance matches the 4.5V to 5.5V operational window for the target system design.

Memory IC Part Context

This component belongs to the Renesas R1LP0408D series of low-power SRAMs. It shares core specifications with variants such as R1LP0408DSB-5SI#S1 and R1LP0408DSP-5SI#B0, differing primarily in packaging format and suffix codes. The series is designed for general-purpose memory applications requiring reliable volatile storage.
