1. Description

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.

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_PPinput is below 0.4V, the program

and erase functions are inhibited. When V_PPis at 1.65V or above, normal program

and erase operations can be performed. With V_PPat 10.0V, the program (Dual-word

Program command) operation is accelerated.
