The S29AL004D90BFI010 is a 4 Mbit (512 K x 8 bit) CMOS 3.0 Volt-only, simultaneous Read/Write Flash memory manufactured by Spansion. This device is designed for high-performance, low-power applications requiring fast and reliable non-volatile storage. The '90' likely signifies a different speed grade (90ns Access time) compared to some of the '70' versions above.

Applications

• Embedded systems
• Wireless communication devices
• Handheld devices
• Automotive applications (instrument clusters, infotainment systems)
• Industrial control systems

Features

• Single 3.0 Volt Read and Write Operations: Simplifies system design and reduces power consumption.
• Simultaneous Read/Write Operation: Allows for concurrent read and write operations, improving system performance.
• Page Mode Operation: Enables fast page programming and erasing.
• Sector Erase Architecture: Provides flexible memory management.
• Top or Bottom Boot Block Configurations Available: Offers flexibility in system design.
• Data# Polling and Toggle Bit support: Simplifies end-of-write detection.
• Low Power Consumption: Extends battery life in portable applications.
• Industry-Standard Packaging: Available in various packages for easy integration.
• 90 ns Access Time Still reasonably high-speed data retrieval for many applications, though slightly slower than the 70ns versions.
