... Typical 10,000 Write Cycles Description The AT49F020 is a 5-volt-only in-system Flash Memory. Its 2 megabits of memory is organized as 262,144 words by 8 bits. Manufactured with Atmel’s advanced nonvola- tile CMOS technology, the device offers access times with power dissipation of just 275 mW over the commercial temperature range. When the device is dese- lected, the CMOS standby current is less than 100 A ...

... The boot sector is designed to contain user secure code, Block Diagram Device Operation READ: The AT49F020 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 ...

Voltage on OE with Respect to Ground ...................................-0.6V to +13.5V TOGGLE BIT: In addition to DATA polling the AT49F020 provides another method for determining the end of a pro- gram or erase cycle. During a program or erase operation, successive attempts to read data from the device will result in I/O6 toggling between one and zero ...
