... Common Flash Interface (CFI) Description The AT49BV320C( 2.7-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 47-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 ...

... This feature will put the erase or program on hold for any amount of time and let the user read data from or program data to any of the remaining sectors within the memory. The VPP pin provides data protection. When the V erase functions are inhibited. When V tions can be performed. AT49BV320C( A16 ...

... Device READ: When the AT49BV320C( the read mode, with CE and OE low and WE high, the data stored at the memory location determined by the address pins are asserted on the out- Operation puts. The outputs are put in the high impedance state whenever high. This dual- line control gives designers flexibility in preventing bus contention ...

... If a Program or Erase operation is attempted to one of the locked sectors, this bit is set by the WSM. The operation specified is aborted and the device is returned to read status mode. This bit is reserved for future use and should be masked out when polling the status register. AT49BV320C(T) PSS SLS 2 1 ...

... The Read command must be issued before data can be read from the memory array. The status register can also be cleared by resetting the device. FLEXIBLE SECTOR PROTECTION: The AT49BV320C(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 ...

For details, see “Operating Modes” on page 21. 128-BIT PROTECTION REGISTER: The AT49BV320C(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 sectors. The two sectors are designated as sector A and sector B. The data in sector 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 4 on page 27. To return to the read mode, issue the Read command. HARDWARE DATA PROTECTION: The Hardware Data Protection feature protects against inadvertent programs to the AT49BV320C(T) in the following ways: (a) V below 1.8V (typical), the program function is inhibited. (b) V reached the V gramming ...
