... Green (Pb/Halide-free) Packaging 1. Description The AT49BV642D( 2.7-volt 64-megabit Flash memory organized as 4,194,304 words of 16 bits each. The memory is divided into 135 sectors for erase operations. The device can be read or reprogrammed off a single 2.7V power supply, making it ideally suited for in-system programming. ...

... Read The AT49BV642D(T) is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins are asserted on the out- puts. The outputs are put in the high impedance state whenever high. This dual-line control gives designers flexibility in preventing bus contention ...

... I/O3, I/O5, I/O6, and I/O7. All other status bits are don’t care. The and the following four sections describe the function of these bits. To provide greater flexibility for system designers, the AT49BV642D(T) contains a programmable configuration register. The configuration register allows the user to specify the status bit operation. The configuration regis- ter can be set to one of two different values, “ ...

... Data Polling The AT49BV642D(T) features Data Polling to indicate the end of a program cycle. If the status configuration register is set to a “00”, during a program cycle an attempted read of the last word loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been completed, true data is valid on all outputs and the next cycle may begin. During a chip or sector erase operation, an attempt to read the device will give a “ ...

... Protection Register The AT49BV642D(T) contains a 128-bit register that can be used for security purposes in sys- tem design. The protection register is divided into two 64-bit blocks. The two blocks are designated as block A and block B. The data in block A is non-changeable and is programmed at the factory with a unique number ...

(c) Program inhibit: holding any one of OE low, CE high or WE high inhibits program cycles ...
