Description

The NexFlash™ NX26F080A and NX26F160 Serial Flash

Memories are tailored for portable/mobile media-storage

applications that transfer and store data, audio and images.

Manufactured using NexFlash’s patented single transistor

EEPROM memory cell, the NX26F080A and NX26F160

provide a high-density, low-voltage, low-power, and cost

effective solution for battery-operated nonvolatile data stor-

age requirements. The NX26F080A and NX26F160 can

operate with a single 5V or 3V supply for Read, Write, and

Erase. Power consumption is very low due to µA standby

current and fast Erase/Write performance (as fast as 5 ms

per sector) that minimizes power-on time, resulting in a

highly efficient energy-per-transfer ratio. The NX26F080A

and NX26F160 offer 8M-bits and 16M-bits of Flash memory

organized in sectors of 536 bytes each. Each sector is

individually addressable through basic commands or con-

trol functions such as Reset, Read, Erase/Write, and

Ready/Busy. The NXS (NexFlash Serial) 2-wire serial

interface is ideal for use with microcontrollers since it only

requires two pins. This leaves pins normally used for parallel

Flash free for other uses. The NXS interface supports clock

rates as fast as 16 MHz and allows for multi-device cascading

of up to 16 devices. It also simplifies PC-board layout and

generates less transient noise than parallel devices. Devel-

opment is supported with the NexFlash Serial Flash

Development Kit.
