 FLASH MEMORY
⢠Simultaneous Read/Write operations (Dual Bank)
⢠FlexBankTM*1
Bank A : 8 Mbit (8 KB Ã 8 and 64 KB Ã 15)
Bank B : 24 Mbit (64 KB Ã 48)
Bank C : 24 Mbit (64 KB Ã 48)
Bank D : 8 Mbit (8 KB Ã 8 and 64 KB Ã 15)
Two virtual Banks are chosen from the combination of four physical banks (Refer to âExample of Virtual Banks
Combination tableâ and âSimultaneous Operation tableâ) .
Host system can program or erase in one bank, and then read immediately and simultaneously from the other
bank with zero latency between read and write operations.
Read-while-erase
Read-while-program
⢠Single 3.0 V read, program, and erase
Minimized system level power requirements
⢠Minimum 100,000 program/erase cycles
⢠Sector erase architecture
Sixteen 4 Kword and one hundred twenty-six 32 Kword sectors in word.
Any combination of sectors can be concurrently erased. It also supports full chip erase.
⢠HiddenROM region
256 byte of HiddenROM, accessible through a new âHiddenROM Enableâ command sequence
Factory serialized and protected to provide a secure electronic serial number (ESN)
⢠WP/ACC input pin
At VIL, allows protection of âoutermostâ 2 Ã 8 Kbytes on both ends of boot sectors, regardless of sector protection/
unprotection status
At VIH, allows removal of boot sector protection
At VACC, increases program performance
⢠Embedded EraseTM*2 Algorithms
Automatically preprograms 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, the device automatically switches itself to low power mode.
⢠Low VCCf write inhibit ⤠2.5 V
⢠Program Suspend/Resume
Suspends the program operation to allow a read in another byte
⢠Erase Suspend/Resume
Suspends the erase operation to allow a read data and/or program in another sector within the same device
⢠Please refer to âMBM29DL64DFâ data sheet in detailed function
