Description
The AT49F16X4(T) is a 5.0-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 40 sec-
tors for erase operations. The device is offered in 48-lead TSOP and 48-ball μBGA
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.
The device powers on in the read mode. Command sequences are used to place the
device in other operation modes such as program and erase. The device has the
Rev. 0977J–04/00
