Description  
The AT49BV/LV3218(T) is a 2.65- to 3.3-volt (BV)/3.0V to 3.6V (LV) 32-megabit Flash  
memory organized as 2,097,152 words of 16 bits each or 4,194,304 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 71 sectors for erase operations. The device is offered in 48-  
lead TSOP and 48-ball CBGA packages. The device has CE and OE control signals to  
avoid any bus contention. This device can be read or reprogrammed using a single  
2.65V power supply, making it ideally suited for in-system programming.
