64-Mbit (4M x 16), 2.7-Volt Sectored Flash, Bottom Boot Block.

The AT49BV640D(T) is a 2.7-volt 64-megabit Flash memory organized as 4,194,304 words of 16 bits each. The memory is divided into 135 sectors for erase operations. The device is offered in a 48-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-system 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
