The AT49SN6416(T) is a 1.8-volt 64-megabit Flash memory. The memory is divided into multiple sectors and planes for erase operations. The device can be read or reprogrammed off a single 1.8V power supply, making it ideally suited for In-System programming. The device can be configured to operate in the asynchronous/page read (default mode) or burst read mode. The burst read mode is used to achieve a faster data rate than is possible in the asynchronous/page read mode. If the AVD and the CLK signals are both tied to GND and the burst configuration register is configured to perform asynchronous reads, the device will behave like a standard asynchronous Flash memory. In the page mode, the AVD signal can be tied to GND or can be pulsed low to latch the page address. In both cases the CLK can be tied to GND. The AT49SN6416(T) is divided into four memory planes. A read operation can occur in any of the three planes which is not being programmed or erased. This concurrent operation allows improved system performance by not requiring the system to wait for a program or erase operation to complete before a read is performed. To further 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
