Preliminary
1. Description
The AT49SV802A(T) is a 1.8-volt 8-megabit Flash memory organized as 524,288
words of 16 bits each or 1,048,576 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 23 sec-
tors for erase operations. The AT49SV802A(T) is offered in a 48-lead TSOP and 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
鈥淪ector Lockdown鈥?on page 7).
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 end of a program or an erase cycle is detected by the
READY/BUSY pin, Data Polling or by the toggle bit.
