Features
1. Description
The AT49BV160C(T) is a 2.7-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 46-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.

... RESET pin, the device returns to the read mode, depending upon the state of the control inputs. 4.4 Erasure Before a word can be reprogrammed, it must be erased. The erased state of memory bits is a logical “1”. The individual sectors can be erased by using the Sector Erase command. 4.4.1 Sector Erase The device is organized into 39 sectors (SA0 - SA38) that can be individually erased ...

... The status register indicates the status of device operations and the success/failure of that oper- ation. The Read Status Register command causes subsequent reads to output data from the status register until another command is issued. To return to reading from the memory, issue a Read command. The status register bits are output on I/O7 - I/O0. The upper byte, I/O15 - I/O8, outputs 00H when a Read Status Register command is issued ...

... Program Suspend/Program Resume The Program Suspend command allows the system to interrupt a programming operation and then read data from a different word within the memory. After the Program Suspend command is given, the device requires a maximum of 20 µs to suspend the programming operation. After the programming operation has been suspended, the system can then read data from any other word within the device ...
