AT49BV512-15JC

... Typical 10,000 Write Cycles Description The AT49BV512 is a 3-volt only, 512K Flash memories organized as 65,536 words of 8 bits each. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times with power dissipation of just 90 mW over the commercial temperature range. When the devices are deselected, the CMOS standby current is less than 50 µ ...

... Block Diagram Device Operation READ: The AT49BV512 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 is 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 ...

... For details, see Operating Modes (for hardware operation) or Software Product Identifi- cation. The manufacturer and device code is the same for both modes. DATA POLLING: The AT49BV512 features DATA polling to indicate the end of a pro- gram cycle. During a program cycle an attempted read of the last byte loaded will result in the complement of the loaded data on I/O7 ...
