... Green (Pb/Halide-free) Packaging 1. Description The AT49BV160D( 2.7-volt 16-megabit Flash memory organized as 1,048,576 words of 16 bits each. The memory is divided into 39 sectors for erase operations. The device is offered in a 48-lead TSOP 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 ...

... Read When the AT49BV160D( 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. 3591C– ...

... 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 AT49BV160D(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. AT49BV160D(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. AT49BV160D(T) PSS SLS 2 1 ...

... Protection Register The AT49BV160D(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 ...
