Contact Factory for availability Part Number Example: MT28F800B3WG-9 40-Pin TSOP Type I 48-Pin TSOP Type I 44-Pin SOP The MT28F008B3 x8 and MT28F800B3 x16/x8 are low-voltage, nonvolatile, electrically block-erasable flash , programmable memory devices containing 8,388,608 bits organized as 524,288 words 16 bits or 1,048,576 bytes 8 bits . Writing and erasing the device is done with a VPP voltage of either 3.3V or 5V, while all operations are performed with a 3.3V VCC. Due to process technology advances, 5V VPP is optimal for application and production programming. These devices are fabricated with Micron’s advanced 0.18µm CMOS floating-gate process. The MT28F008B3 and MT28F800B3 are organized into eleven separately erasable blocks. To ensure that critical firmware is protected from accidental erasure or overwrite, the devices feature 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.
