Product Summary
The MT28F800B5WG-8B is a nonvolatile, electrically block-erasable (Flash), programmable read-only memory containing 8,388,608 bits organized as 524,288 words (16 bits) or 1,048,576 bytes (8 bits). Writing or erasing the device is done with a 5V VPP voltage, while all operations are performed with a 5V VCC. Due to process technology advances, 5V VPP is optimal for application and production programming. The MT28F800B5WG-8B is fabricated with Micron advanced 0.18μm CMOS floating-gate process. The MT28F800B5WG-8B is organized into eleven separately erasable blocks. To ensure that critical firmware is protected from accidental erasure or overwrite, the device features a hardware-protected boot block. This block may be used to store code implemented in low-level system recovery. The remaining blocks vary in density and are written and erased with no additional security measures.
