• Boot Code Sector Architecture
MB84VA2004: Top sector
MB84VA2005: Bottom sector
• Embedded Erase^TM Algorithms
Automatically pre-programs and erases the chip or any sector
• Embedded Program^TM Algorithms
Automatically writes and verifies data at specified address
• Data Polling and Toggle Bit feature for detection of program or erase cycle completion
• Ready-Busy output (RY/BY)
Hardware method for detection of program or erase cycle completion
• Automatic sleep mode
When addresses remain stable, automatically switch themselves to low power mode.
• Low VCC write inhibit ≤ 2.5 V
• Erase Suspend/Resume
Suspends the erase operation to allow a read in another sector within the same device
