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 VPP input is below 0.4V, the program  
and erase functions are inhibited. When VPP is at 1.65V or above, normal program  
and erase operations can be performed. With VPP at 10.0V, the program (Dual-word  
Program command) operation is accelerated.
