... The AT49BV162A(T)/163A(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 outputs. The outputs are put in the high impedance state whenever high. This dual- line control gives designers flexibility in preventing bus contention ...

... Byte/Word Programming Once a memory block is erased programmed (to a logical “0” byte-by-byte word-by-word basis. Programming is accomplished via the internal device command register and is a four-bus cycle operation. The device will automatically generate the required internal program pulses ...

... In addition to Data Polling the AT49BV162A(T)/163A(T) provides another method for determin- ing the end of a program or erase cycle. During a program or erase operation, successive attempts to read data from the memory will result in I/O6 toggling between one and zero. Once the program cycle has completed, I/O6 will stop toggling and valid data will be read. Examining the toggle bit may begin at any time during a program cycle ...

Erase/Program Status Bit The device offers a status bit on I/O5, which indicates whether the program or erase operation has exceeded a specified internal pulse count limit. If the status bit is a “1”, the device is unable to ...

... Erase Suspend/Erase Resume The Erase Suspend command allows the system to interrupt a sector or chip erase operation and then program or read data from a different sector within the memory. After the Erase Sus- pend command is given, the device requires a maximum time of 15 µs to suspend the erase operation ...
