MBM29DL64DF is a 64 M-bit, 3.0 V-only Flash memory organized as 8 Mbytes of 8 bits each or 4 M words of 16bits each. The device comes in 48-pin TSOP (1) and 48-ball FBGA packages. This device is designed to be programmed in system with 3.0 V VCCsupply. 12.0 V VPPand 5.0 V VCCare not required for write or erase operations.
The device can also be reprogrammed in standard EPROM programmers. The device is organized into four physical banks : Bank A, Bank B, Bank C and Bank D, which are considered to be four separate memory arrays operations. This device is the almost identical to Fujitsu’s standard 3 V only Flash memories, with the additional capability of allowing a normal non-delayed read access from a non-busy bank of the array while an embedded write (either a program or an erase) operation is simultaneously taking place on the other bank.
