8 Mbit Boot Block Flash for 16-bit buses
The Intel DE28F800F3T95 is an 8 Mbit non-volatile Flash memory from the ETOX™ series, organized as 512K x 16 bits. It uses a Boot Block architecture, which allows individual sectors to be locked for code protection while the rest of the array is updated. The 95 ns access time sets the read-cycle budget for the host controller — fast enough for most 16-bit MCUs and DSPs without wait states on a 3.3V bus. Supply range is 3V to 3.6V, so it runs directly off a 3.3V rail. The industrial temperature grade (-40°C to 125°C) qualifies it for outdoor telecom, motor drives, and under-hood automotive modules. Package is a 56-pin SSOP (surface mount), the same footprint used across the 8 Mbit density tier.
95 ns access — timing margin on a 16-bit bus
Write-cycle time is 200 µs per word or page.
This part is specified for a 3.3V-only supply, 16-bit data bus, and surface-mount assembly in the 56-SSOP package. If your BOM calls for the 95 ns speed grade and the Boot Block feature set, the DE28F800F3T95 is the exact ordering code. We source it through independent distribution and can quote against your line-item quantity and required delivery window.
