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

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 V

and erase functions are inhibited. When V

and erase operations can be performed. With V

Program command) operation is accelerated.
