... VCCQ supply pin. The device can operate in the asynchronous or page read mode. The AT49BV6416(T) is divided into four memory planes. A read operation can occur in any of the three planes which is not being programmed or erased. This concurrent operation allows improved system performance by not requiring the system to wait for a program or erase operation to complete before a read is performed ...

... Asynchronous Read The AT49BV6416(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 con- trol gives designers flexibility in preventing bus contention ...

... Flexible Sector Protection The AT49BV6416(T) offers two sector protection modes, the Softlock and the Hardlock. The Softlock mode is optimized as sector protection for sectors whose content changes frequently. The Hardlock protection mode is recommended for sectors whose content changes infrequently. ...

... Data Polling The AT49BV6416(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 “ ...

... VPP Status Bit The AT49BV6416(T) provides a status bit on I/O3 that provides information regarding the volt- age level of the VPP pin. During a program or erase operation, if the voltage on the VPP pin is not high enough to perform the desired operation successfully, the I/O3 status bit will be a “1”. ...

... Protection Register The AT49BV6416(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 ...

... During chip erase, a valid address is any non-protected sector address. 2. I/O7 should be rechecked even if I/O5 = “1” because I/O7 may change simultaneously with I/O5. AT49BV6416(T) 9 Figure 3-3. YES Note: Program/Erase ...
