Description
The AT49F8011(T) is a 5.0 volt 8-megabit Flash memory organized as 524,288 words
of 16 bits each or 1,048,576 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 22 sectors for
erase operations. The device is offered in 48-pin TSOP and 48-ball CBGA packages.
The device has CE, and OE control signals to avoid any bus contention. This device
can be read or reprogrammed using a single 5.0V power supply, making it ideally
suited for in-system programming.
