1. Description
The AT49BV160D(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
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 VPP pin provides data protection. When the V

- Page 3 Read When the AT49BV160D(T) is in the read mode, with CE and OE low and WE high, the data stored at the memory location determined by the address pins are asserted on the outputs. The outputs are put in the high impedance state whenever CE or OE is high. This dual-line control gives designers flexibility in preventing bus contention.
- Page 4 I/O7 is “0”. While programming, the only valid commands are Read Status Register, Program Suspend and Program Resume. VPP Pin The circuitry of the AT49BV160D(T) is designed so that the device cannot be programmed or erased if the V voltage is less that 0.4V. When V is at 1.65V or above, normal program and...
- Page 5 AT49BV160D(T) Read Status Register 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.
- Page 6 Flexible Sector Protection The AT49BV160D(T) offers two sector protection modes, the Softlock and the Hardlock. The Softlock mode is optimized as sector protection for sectors whose content changes frequently. The Hardlock protection mode is recommended for sectors whose content changes infrequently.

The data in sector A is non-changeable and is pro- grammed at the factory with a unique number.
