1.
The AT49BV320D(T) is a 2.7-volt 32-megabit Flash memory organized as 2,097,152
words of 16 bits each. The memory is divided into 71 sectors for erase operations.
The device is offered in a 48-lead TSOP package and a 47-ball CBGA package. The
device has CE and OE control signals to avoid any bus contention. This device can be
read or reprogrammed using a single power supply, making it ideally suited for in-sys-
tem programming.
Description
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 capability to protect the data in any sector (see
“Flexible Sector Protection” on
page 6
).
To increase the flexibility of the device, it contains an Erase Suspend and Program
Suspend feature. This feature will put the erase or program on hold for any amount of
time and let the user read data from or program data to any of the remaining sectors
within the memory.
The VPP pin provides data protection. When the V
PP
input is below 0.4V, the program
and erase functions are inhibited. When V
PP
is at 1.65V or above, normal program
and erase operations can be performed. With V
PP
at 10.0V, the program (Dual-word
Program command) operation is accelerated.
