... Green (Pb/Halide-free) Packaging Option 1. Description The AT49SV322A( 1.8-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. AT49SV322A(T) 2 input is below 0.4V, the program and erase ...

... Read The AT49SV322A(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 ...

... 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. 3360E–FLASH–10/05 AT49SV322A(T) .

... I/O7 status bit as described below. 4.7.1 Data Polling The AT49SV322A(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 AT49SV322A(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 AT49SV322A(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 ...

... RDY/BUSY For the AT49SV322A(T), an open-drain READY/BUSY output pin provides another method of detecting the end of a program or erase operation. RDY/BUSY is actively pulled low during the internal program and erase cycles and is released at the completion of the cycle. The open-drain connection allows for OR-tying of several devices to the same RDY/BUSY line. See Table” ...

... 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. AT49SV322A(T) 10 Figure 4-2.
