... Green (Pb/Halide-free) Packaging Option 1. 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 ...

... Device Operation 4.1 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 outputs. The outputs are put in the high impedance state whenever high. This dual-line control gives designers flexibility in preventing bus contention ...

... I/O7 is “0”. While programming, the only valid commands are Read Status Register, Program Suspend and Program Resume. 4.6 VPP Pin The circuitry of the AT49BV320C(T) is designed so that the device cannot be programmed or erased if the V erase operations can be performed. The VPP pin cannot be left floating. AT49BV320C(T) 4 voltage is less that 0 ...

... 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 ...

... 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. The Hardlock protection mode is recommended for sectors whose content changes infrequently. ...

... Protection Register The AT49BV320C(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 sectors. The two sectors are designated as sector A and sector B. The data in sector A is non-changeable and is pro- grammed at the factory with a unique number ...

... Hardware Data Protection The Hardware Data Protection feature protects against inadvertent programs to the AT49BV320C(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 tions are inhibited for 100 ns ...
