NM29A040 080 .. 4-Mbit 8-Mbit CMOS Serial FLASH E2PROM
General Description
The NM29A040 080 are 4-Mbit and 8-Mbit Flash memories designed with a MICROWIRETM serial interface All of the Features of the device are designed to provide the most cost effective solution for applications requiring low bandwidth file storage Examples of these applications include digital answering machines and personal digital recorders (digital audio) or FAX and digital scanners (digital imaging) The Serial Flash requires only a single 5V power supply has a small erase block size (4 kbytes) and a low EMI serial interface The NM29A040 080 have been designed to work seamlessly with National’s pact RISCTM family (e g NSAM266) of processors In this manner National is able to provide the plete system solution to digital audio recording (processor CODEC Flash memory software) or digital imaging
Features
Single 5V g 10% power supply 4 kbyte erase block Organized as 128 (256) Blocks per 4-Mbit (8-Mbit) Device 128 pages per block 32 bytes per page (256 bits) MICROWIRETM patible interface Low operating current (typical) 5 m A read current 15 m A write current 10 m A erase current 5 m A standby current 100k write erase cycle endurance Offered in PLCC and SOIC packages
