1. Description
The AT49BV320C(T) is a 2.7-volt 32-megabit Flash memory organized as 2,097,152
words of 16 bits each. The memory is divided into 71 sectors for erase operations.
The device is offered in a 48-lead TSOP and a 47-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
page
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 V
and erase functions are inhibited. When V
erase operations can be performed.
