Description

The

NexFlashTM 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

A 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.
