... Common Flash Interface (CFI) 1. Description The AT49SV322D( 1.8-volt 32-megabit Flash memory organized as 2,097,152 words of 16 bits each. The memory is divided into 71 sectors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball CBGA package. The device has CE and OE control signals to avoid any bus contention. This device can be read or reprogrammed using a single power supply, making it ideally suited for in-system programming ...

... Read The AT49SV322D(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. 3623A– ...

... Programming is completed after the specified t time. The Data Polling feature or the Toggle Bit feature may be used to indicate the end of a program cycle. If the erase/program status bit is a “1”, the device was not able to verify that the erase or program operation was performed successfully. AT49SV322D( ...

... Data Polling The AT49SV322D(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 AT49SV322D(T) provides a status bit on I/O3, which provides information regarding the voltage 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 “ ...

... Protection Register The AT49SV322D(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 ...

... Hardware Data Protection The Hardware Data Protection feature protects against inadvertent programs to the AT49SV322D(T) in the following ways: (a) V gram function is inhibited. (b) V the device will automatically time out 10 ms (typical) before programming. (c) Program inhibit: holding any one of OE low, CE high or WE high inhibits program cycles. (d) Program inhibit: ...

... 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. AT49SV322D(T) 9 Figure 4-2. YES Program/Erase Operation ...
