The boot-block architecture provides hardware-protected sectors for critical boot code, preventing accidental corruption during power-loss or incomplete writes — a feature that matters for embedded systems where the CPU must come up cleanly after a brownout. Rated for -40°C to 125°C operation, this part is suited for industrial motor drives, automotive under-hood controllers, and avionics data-logging modules where the ambient temperature exceeds standard commercial limits. ## 115 ns access time — what it means for bus timing The 115 ns access time is the window from address assertion to valid data on the bus. Write cycle time is 200 µs per word or page. ## Boot Block architecture and field-reprogramming Boot-block Flash partitions the memory array into independently lockable sectors, with the boot block (typically the lowest address range) protected by a hardware write-lock mechanism. This prevents a runaway firmware update from bricking the system — the bootloader stays intact even if the application sector is corrupted mid-write. The CUI command set follows the industry-standard 12V-block erase/program algorithm, so existing firmware drivers for Intel 28F-series Flash should port with minimal changes. No field-reprogramming via UART or JTAG is built in; the host CPU manages all erase and program sequences through the parallel interface. ## Package and temperature grade — where it fits physically Housed in a 56-SSOP surface-mount package, this part operates from -40°C to 125°C and from 3V to 3.6V.","metaTitle":"DE28F800F3T115 Flash Memory, 8Mbit 115ns Boot Block 56-SSOP","metaDescription":"Intel DE28F800F3T115 8Mbit boot-block Flash, 115 ns access time, 3V-3.6V, -40°C to 125°C.
