CAT93C46
1 Kb Microwire Serial
EEPROM
Description
The CAT93C46 is a 1 Kb Serial EEPROM memory device which is
configured as either 64 registers of 16 bits (ORG pin at VCC) or 128
registers of 8 bits (ORG pin at GND). Each register can be written (or
read) serially by using the DI (or DO) pin. The CAT93C46 features a
self−timed internal write with auto−clear. On−chip Power−On Reset
circuit protects the internal logic against powering up in the wrong
state.
Features
• High Speed Operation: 2 MHz
• 1.8 V to 5.5 V Supply Voltage Range
• Selectable x8 or x16 Memory Organization
• Self−Timed Write Cycle with Auto−Clear
• Software Write Protection
• Power−up Inadvertant Write Protection
• Low Power CMOS Technology
• 1,000,000 Program/Erase Cycles
• 100 Year Data Retention
• Industrial Temperature Range
• 8−pin PDIP, SOIC, TSSOP and 8−pad TDFN Packages
• This Device is Pb−Free, Halogen Free/BFR Free and RoHS
Compliant*

Note: When the ORG pin is connected to VCC, the
x16 organization is selected. When it is connected
to ground, the x8 organization is selected. If the
ORG pin is left unconnected, then an internal pullup
device will select the x16 organization.
