S29GL032N90DFBR23

Memory IC Overview

The S29GL032N90DFBR23 is a 32 Megabit (4M x 8 or 2M x 16) NOR Flash memory device manufactured by Spansion. It utilizes the MirrorBit architecture and operates at a single 3V supply voltage. The component features a maximum access time of 90 ns and supports both page mode and random access operations. It is housed in a 64-pin Lead-Free Fine-Pitch Ball Grid Array (FBGA) package with dimensions of 9x9 mm. The device includes a command user interface, data polling, and general flash interface capabilities for embedded system integration.

Memory IC Feature Summary

• MirrorBit technology enables high-density storage within a compact footprint
• Supports 3V single-supply operation for low-power applications
• Includes command user interface and data polling for efficient control

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Automotive electronics applications
• Industrial control systems

Memory IC Procurement Notes

Verify the specific suffix 'R23' against official Spansion documentation to confirm lead-free status and package variant accuracy. Confirm lifecycle status as obsolete before procurement planning. Ensure compatibility with existing board layouts for the 64-FBGA form factor. Cross-reference ECCN codes for export compliance requirements.

Memory IC Selection Notes

Select this component when a 32Mbit capacity with 90ns speed is required in a small FBGA package. Consider the 3V operating voltage constraint for power supply design. Evaluate the MirrorBit architecture benefits for density versus traditional cell designs. Verify that the parallel interface matches the host controller's bus width and timing requirements.

Memory IC Part Context

This part belongs to the S29GL-N series of high-density NOR flash memories. The series is designed for embedded applications needing reliable code execution and data storage. Spansion, now part of Cypress Semiconductor, developed this line to support automotive and industrial markets with robust performance characteristics.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes within the S29GL032N family. Verify if newer generations from the manufacturer offer equivalent specifications. Ensure any replacement maintains the same 64-FBGA package and 3V operation.
