... Common Flash Interface (CFI) 1. Description The AT49BV322D( 2.7-volt 32-megabit Flash memory organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. The x16 data appears on I/O0 - I/O15; the x8 data appears on I/O0 - I/O7. The memory is divided into 71 sec- tors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball CBGA package ...

... If the BYTE pin is set at logic “0”, the device is in byte configuration, and only data I/O pins I/O0 - I/O7 are active and controlled by CE and OE. The data I/O pins I/O8 - I/O14 are tri-stated, and the I/O15 pin is used as an input for the LSB (A-1) address function. AT49BV322D(T) 2 input is below 0.4V, the program and erase ...

... 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. 3582B–FLASH–11/05 AT49BV322D(T) .

... I/O7 status bit as described below. 4.7.1 Data Polling The AT49BV322D(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 byte/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 AT49BV322D(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 “1”. ...

... Protection Register The AT49BV322D(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 AT49BV322D(T) in the following ways: (a) V function is inhibited. (b) V device will automatically time out 10 ms (typical) before programming. (c) Program inhibit: hold- ing any one of OE low, CE high or WE high inhibits program cycles. (d) Program inhibit: V less than V 4 ...

... VA = Valid address for programming. During a sector erase operation, a valid address is any sector address within the sector being erased. 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. AT49BV322D(T) 10 Figure 4-2.

The system should recheck the toggle bit even if I/O5 = “1” because the toggle bit may stop toggling as I/O5 changes to “1”. 3582B–FLASH–11/05 Figure 4- Program/Erase Operation Successful, Device in Read Mode Note: AT49BV322D(T) Toggle Bit Algorithm (Configuration Register = 01) START Read I/O7 - I/O0 Read I/O7 - I/O0 NO Toggle Bit = Toggle?
