Features
Description
The AT49F1024 and the AT49F1025 are 5-volt-only in-system Flash memories. Their
1 megabit of memory is organized as 65,536 words by 16 bits. Manufactured with
Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to
35 ns with power dissipation of just 275 mW over the commercial temperature range.
When the device is deselected, the CMOS standby current is less than 100 µA. The
only difference between the AT49F1024 and the AT49F1025 is the package.
To allow for simple in-system reprogrammability, the AT49F1024/1025 does not
require high-input voltages for programming. Five-volt-only commands determine the

... ADDRESS INPUTS X DECODER READ: The AT49F1024/1025 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 AT49F1024/1025 features Data Polling to indicate the end of a program or erase 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 ...
