The LH28F008SCHR-85 is an 8-Mbit (1M x 8) Flash Memory device manufactured by Sharp Microelectronics. It's a NOR-type flash memory, known for its fast read speeds and suitability for code storage and execution.

Applications:

• Embedded systems
• Microcontrollers
• Industrial control equipment
• Networking devices
• Handheld devices
• Consumer electronics

Features:

• 8-Mbit (1M x 8) organization
• NOR flash architecture
• Fast read access time (85ns)
• Single 5V power supply
• Sector Erase capability
• Top Boot Sector configuration
• Common Flash Interface (CFI) compliant
• TSOP package

Benefits:

• Fast Code Execution: NOR flash allows for direct code execution from memory, enabling quick system startup and response times.
• Non-Volatile Storage: Retains data even when power is removed.
• In-System Programmability: Can be programmed and erased while still installed in the system, simplifying updates and revisions.
• High Density: 8-Mbit capacity provides ample storage space for code and data.
• Sector Erase: Allows for selective erasing of memory blocks, minimizing erase times and wear.
• Industry Standard Interface: CFI compliance ensures compatibility with a wide range of microcontrollers and development tools.

The LH28F008SCHR-85 is designed for applications that require fast read access and reliable non-volatile storage. The 85ns access time ensures quick data retrieval, while the sector erase capability allows for efficient memory management. The top boot sector configuration is suitable for systems that boot from flash memory. The TSOP package provides a compact footprint for space-constrained applications. This part is often utilized in older embedded designs where this density and interface are still relevant.
