1. Description
The AT49SV163D(T) is a 1.8-volt 16-megabit Flash memory organized as 1,048,576
words of 16 bits each. The memory is divided into 39 sectors for erase operations.
The device 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 “Sector Lockdown” 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 end of a program or an erase cycle is detected by the
READY/BUSY pin, Data Polling or by the toggle bit.
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 at 10.0V, the program (Dual-word
Program command) operation is accelerated.
