Miltiple devices available with different bank sizes
Host system can program or erase in one bank, then immediately and simultaneously read from the other bank
Zero latency between read and write operations
Read-while-erase
Read-while-program
Eight 4 K words and thirty one 32 K words.
Any combination of sectors can be concurrently erased. Also supports full chip erase.
MB84VD2108X : Top sector
MB84VD2109X : Bottom sector
Automatically pre-programs and erases the chip or any sector
Automatically writes and verifies data at specified address
Hardware method for detection of program or erase cycle completion
When addresses remain stable, automatically switch themselves to low power mode.
64K byte of Hi-ROM, accessible through a new “Hi-ROM Enable” command sequence
Factory serialized and protected to provide a secure electronic serial number (ESN)
