1.FLASH MEMORY Simultaneous Read/Write operations (dual bank) 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 Minimum 100,000 write/erase cycles Sector erase architecture Eight 4 K words and sixty three 32 K words. Any combination of sectors can be concurrently erased. Also supports full chip erase. Boot Code Sector Architecture MB84VD2218X: Top sector MB84VD2219X: Bottom sector Embedded EraseTM Algorithms Automatically pre-programs and erases the chip or any sector Embedded ProgramTM 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 VCCf write inhibit 2.5 V Hidden ROM (Hi-ROM) region 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) WP/ACC input pin At VIL, allows protection of boot sectors, regardless of sector protection/unprotection status MB84VD2219XEC/EE:SA0,SA1) At VIH, allows removal of boot sector protection At VACC, program time will reduse by 40%. Erase Suspend/Resume Suspends the erase operation to allow a read in another sector within the same device Please refer to "MBM29DL32XTE/BE" data sheet in detailed function 2.SRAM Power dissipation Operating 50 mA max. Standby 15 A max. Power down features using CE1s and CE2s Data retention supply voltage: V CE1s and CE2s Chip Select Byte data control: LBs(DQ0-DQ7), UBs(DQ8-DQ15)
