... Green (Pb/Halide-free) Packaging Option 1. 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 39 sectors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball CBGA package ...

... 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 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. 4.6 VPP Pin The circuitry of the AT49BV162A(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. 3349H–FLASH–3/05 ...

... DATA Polling The AT49BV162A(T)/163A(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 “ ...

... Status Bit PP The AT49BV162A(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 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 ...

... Hardware Data Protection The Hardware Data Protection feature protects against inadvertent programs to the AT49BV162A(T)/163A(T) in the following ways: (a) V program function is inhibited. (b) V level, the device will automatically time out 10 ms (typical) before programming. (c) Program inhibit: holding any one of OE low, CE high or WE high inhibits program cycles. (d) Program inhibit: V and erase operations are inhibited for 100 ns ...
