Description

The NexFlash™ NX26F011A and NX26F041A 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 NX26F011A and NX26F041A provide a high-density, low-voltage, low-power, and cost effective solution for battery-operated nonvolatile data storage requirements. The NX26F011A and NX26F041A 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 NX26F011A
PRE-RELEASE MAY 1999 and NX26F041A offer 1M-bits and 4M-bits of Flash memory organized in sectors of 264 bytes each. Each sector is individually addressable through basic commands or
control 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 NX26F041A interface supports clock rates as fast as 16 MHz and allows for multi-device cascading of up to 16 devices. The NX26F041A  also simplifies PC-board layout and generates less transient noise than parallel devices. Development is supported with the NexFlash Serial Flash Development Kit.
