DE28F800F3T95

Memory IC Overview

The Altera DE28F800F3T95 is a boot block memory integrated circuit designed for system initialization. It features an 8 Mbit capacity organized as 512K x 16 bits. The device utilizes a Common Memory Interface (CUI) and operates within a supply voltage range of 3V to 3.6V. Key performance metrics include a maximum access time of 95 ns and a write cycle time of 200µs per word or page. It is housed in a 56-pin SSOP package, providing a compact solution for embedded storage applications requiring reliable boot code retention.

Memory IC Feature Summary

• Provides dedicated boot block memory for secure system initialization
• Supports Common Memory Interface (CUI) for standard compatibility
• Ensures data integrity with specified write cycle timing

Memory IC Applications

• Embedded system boot code storage
• FPGA configuration bitstream retention
• Microcontroller firmware storage

Memory IC Procurement Notes

Verify the specific suffix T95 against the manufacturer's current datasheet to confirm pinout and thermal specifications. Ensure the design supports the 3V-3.6V operating range. Confirm the 56-SSOP package dimensions match the PCB footprint requirements. Check for any recent product change notices regarding marking or material composition updates.

Memory IC Selection Notes

Select this component when a small, dedicated non-volatile memory block is required specifically for boot purposes rather than general data storage. The 8 Mbit density is suitable for storing initial loading routines. Consider the 95 ns access speed if it meets the processor's bus timing requirements during the boot phase. The SSOP package is appropriate for space-constrained designs where surface mount technology is preferred over through-hole.

Memory IC Part Context

This part belongs to the Altera memory portfolio, often used in conjunction with Altera FPGAs or SoCs. It serves as a companion device to store the primary configuration data or boot loader that initializes the main programmable logic device. This separation allows for flexible system updates while maintaining a stable boot environment.

Memory IC Replacement Considerations

Check for direct cross-reference equivalents from Intel or other manufacturers offering 8 Mbit CUI flash in 56-SSOP. Verify electrical compatibility including voltage levels and interface protocols before substitution.
