S29GL256S90FHSS40

Memory IC Overview

The S29GL256S90FHSS40 is a 256 Mbit (32M x 8 or 16M x 16) Parallel NOR Flash memory component manufactured by Infineon Technologies. It utilizes the MirrorBit technology and operates within a voltage range of 2.7 V to 3.6 V. The device features an asynchronous interface with a maximum access time of 90 ns and a maximum active read current of 60 mA. It is housed in a 64-pin FBGA package (13x11 mm) designed for surface mount installation. The component supports industrial temperature ranges and includes humidity sensitivity classification.

Memory IC Feature Summary

• MirrorBit technology enables high-density storage in a compact footprint
• Asynchronous parallel interface supports standard system integration
• Single voltage supply operation simplifies power design

Memory IC Applications

• Industrial control systems requiring non-volatile code storage
• Automotive electronics applications
• Consumer electronic devices needing firmware storage

Memory IC Procurement Notes

Verify the specific suffix FHSS40 against the official Infineon datasheet to confirm pinout, package dimensions, and electrical characteristics match your design requirements. Ensure compliance with RoHS directives and check moisture sensitivity levels for proper handling during assembly. Confirm availability and lead times through authorized distributors as stock levels fluctuate.

Memory IC Selection Notes

Select this part when a 256 Mbit capacity with 90 ns access speed is required in a small FBGA package. Consider the 16-bit data bus width option if higher bandwidth is needed, noting that the 'H' suffix typically denotes 16-bit organization. Verify thermal performance and operating temperature range suitability for the target environment before finalizing the bill of materials.

Memory IC Part Context

This component belongs to the S29GL256S series of NOR flash memories from Infineon. The series is characterized by its use of floating gate technology and robust reliability features. It is part of the broader GL-S family, which offers various capacities and interfaces for diverse embedded storage needs.

Memory IC Replacement Considerations

Check for direct substitutes within the S29GL256S family with different suffixes that may offer alternative packages or speeds. Cross-reference with other manufacturers' 256 Mbit parallel NOR flashes only if pin compatibility and electrical specifications are identical.
