16-Mbit Flash

Description

The 16-Mbit Flash is organized as 1,048,576 words of 16 bits each. The x16 data appears on

I/O0 - I/O15. The memory is divided into 39 sectors for erase operations. 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” section).

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

input is below 0.4V, the program and

erase functions are inhibited. When V

is at 0.9V or above, normal program and erase opera-

tions can be performed.

A six-byte command (Enter Single Pulse Program Mode) sequence to remove the requirement

of entering the three-byte program sequence is offered to further improve programming time.

After entering the six-byte code, only single pulses on the write control lines are required for

writing into the device. This mode (Single Pulse Word Program) is exited by powering down

the device, or by pulsing the RESET pin low for a minimum of 500 ns and then bringing it back

to V

. Erase, Erase Suspend/Resume and Program Suspend/Resume commands will not

work while in this mode; if entered they will result in data being programmed into the device. It

is not recommended that the six-byte code reside in the software of the final product but only

exist in external programming code.
