Simultaneous Read/Write Operations (Dual Bank)
Multiple devices available with different bank sizes (Refer to “Pin Configuration” in “
s
PIN DESCRIPTION”)
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
•
Minimum 100,000 Write/Erase Cycles
•
Sector Erase Architecture
Eight 4 K words and thirty-one 32 K words.
Any combination of sectors can be concurrently erased. Also supports full chip erase.
•
Boot Code Sector Architecture
MB84VD2118X : Top sector
MB84VD2119X : 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 V

•
Hidden ROM (Hi-ROM) Region
64 K 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)
•
WP/ACC Input Pin
At V
IL
, allows protection of boot sectors, regardless of sector protection/unprotection status
(MB84VD2118XEG : SA37, SA38 MB84VD2119XEG : SA0, SA1)
At V
IH
, allows removal of boot sector protection
At V
ACC
, program time will be reduced by 40%.
•
Erase Suspend/Resume
Suspends the erase operation to allow a read in another sector within the same device
