Product Details


The AT49BV16X4(T) is 2.7 to 3.6 volt 16-megabit Flash memory organized as 1,048,576 words of 16 bits each or 2,097,152 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 40 blocks for erase operations. The device is offered in 48-pin TSOP and 48-ball µBGA packages. The device has CE, and OE control signals to avoid any bus contention. This device can be read or reprogrammed using a single 2.7V 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. Once the data protection for a given sector is enabled, the data in that sector cannot be changed using input levels between ground and VCC.
The device is segmented into two memory planes. Reads from memory plane B may be performed even while program or erase functions are being executed in memory plane A and vice versa. This 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 feature. This feature will put the Erase 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 same memory plane. There is no reason to suspend the erase operation if the data to be read is in the other memory plane. The end of a program or an Erase cycle is detected by the Ready/Busy pin, Data polling, or by the toggle bit.
A VPP pin is provided to improve program/erase times at lower supply voltages. This pin does not need to be utilized. If it is not used the pin should be connected to ground or VCC. To take advantage of faster programming, the pin should supply 5.0 volts during program and erase operations.
