NM93C06LZ
September 1996
NM93C06LZ/C46LZ/C56LZ/C66LZ 256-/1024-/2048-/4096-Bit Serial EEPROM with Zero Power and Extended Voltage (2.7V to 5.5V) (MICROWIRETM Bus Interface)
General Description
The NM93C06LZ/C46LZ/C56LZ/C66LZ devices are 256/ 1024/2048/4096 bits respectively, of CMOS non-volatile electrically erasable memory divided into 16/64/128/256 16-bit registers. They are fabricated using National Semiconductor's floating-gate CMOS process for high reliability and low power consumption. These memory devices are available in both SO and TSSOP packages for small space considerations.
The serial interface that operates these EEPROMs is MICROWIRE compatible for simple interface to standard microcontrollers and microprocessors. There are 7 instructions that control these devices: Read, Erase/Write Enable, Erase, Erase All, Write, Write All, and Erase/Write Disable. The ready/busy status is available on the DO pin to indicate the completion of a programming cycle.
Features
YLess than 1.0 mA standby current
Y2.7V ± 5.5V operation in all modes
YTypical active current of 100 mA
YDirect write: no erase before program
YReliable CMOS floating gate technology
YMICROWIRE compatible serial I/O
YSelf-timed programming cycle
YDevice status indication during programming mode
Y40 years data retention
YEndurance: 106 data changes
YPackages available: 8-pin SO, 8-pin DIP, 8-pin TSSOP
