Two virtual Banks are chosen from the combination of four physical banks (Refer to Table 9, 10)
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
Minimized system level power requirements
Uses the same software commands as E
48-pin TSOP (I) (Package suffix : TN
63-ball FBGA (Package suffix : PBT)
80 ns maximum access time
Sixteen 4 Kword and one hundred twenty-six 32 Kword sectors in word mode
Sixteen 8 Kbyte and one hundred twenty-six 64 Kbyte sectors in byte mode
Any combination of sectors can be concurrently erased. It also supports full chip erase.
256 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)
