... Common Flash Interface (CFI) Description The AT49BV162A(T)/163A( 2.7-volt 16-megabit Flash memory organized as 1,048,576 words of 16 bits each or 2,097,152 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 sectors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball CBGA package ...

... Device READ: 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 Operation 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. ...

... 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. VPP PIN: The circuitry of the AT49BV162A(T) is designed so that the device cannot be pro- grammed or erased if the V program and erase operations can be performed. The VPP pin cannot be left floating. ...

... Please see “Status Bit Table” on page 11 for more details. V STATUS BIT: The AT49BV162A(T) provides a status bit on I/O3, which provides informa- PP tion 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 “ ...

For details, see “Operating Modes” on page 16 or “Software Product Identification Entry/Exit” sections on page 23. 128-BIT PROTECTION REGISTER: The AT49BV162A(T)/163A(T) contains a 128-bit register that can be used for security purposes in system 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 ...

... Once in the CFI Query mode, the system can read CFI data at the addresses given in Table 1 on page 24. To exit the CFI Query mode, the product ID exit command must be given. HARDWARE DATA PROTECTION: The Hardware Data Protection feature protects against inadvertent programs to the AT49BV162A(T)/163A(T) in the following ways: ( below 1.8V (typical), the program function is inhibited. (b) V ...
