Description  
Not Recommended  
The AT49BV640(T) is a 2.7-volt 64-megabit Flash memory. The memory is divided  
into multiple sectors for erase operations. The device can be read or reprogrammed  
off a single 2.7V power supply, making it ideally suited for in-system programming.  
The output voltage can be separately controlled down to 1.65V through the VCCQ  
supply pin. This device can operate in the asynchronous or page read mode.  
for New Design  
Contact Atmel to discuss  
the latest design in trends  
and options  
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.  
The end of a program or an erase cycle is detected by Data Polling or the toggle bit.  
The VPP pin provides data protection and faster programming and erase times. When  
the VPP input is below 0.8V, 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 12.0V, the program and erase operations are accelerated.  
With VPP at 12V, a six-byte command (Enter Single Pulse Program Mode) to remove  
the requirement of entering the three-byte program sequence is offered to further  
improve programming time. After entering the six-byte code, only single pulses on the  
write control lines are required for writing into the device. This mode (Single Pulse  
Word Program) is exited by powering down the device, by taking the RESET pin to  
GND or by a high-to-low transition on the VPP input. Erase, Erase Suspend/Resume,  
Program Suspend/Resume and Read Reset commands will not work while in this  
mode; if entered they will result in data being programmed into the device. It is not rec-  
ommended that the six-byte code reside in the software of the final product but only  
exist in external programming code.
