CAT93C86B
16-Kb Microwire Serial
EEPROM
Description
The CAT93C86B is a 16−Kb Serial EEPROM memory device
which is configured as either registers of 16 bits (ORG pin at V_CC) or 8
bits (ORG pin at GND). Each register can be written (or read) serially
by using the DI (or DO) pin. The CAT93C86B 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: 4 MHz (5 V), 2 MHz (1.8 V)
• 1.8 V (1.65 V*) to 5.5 V Supply Voltage Range
• Selectable x8 or x16 Memory Organization
• Self−timed Write Cycle with Auto−clear
• Sequential Read
• Hardware and Software Write Protection
• Power−up Inadvertent Write Protection
• Low Power CMOS Technology
• Program Enable (PE) Pin
• 1,000,000 Program/Erase Cycles
• 100 Year Data Retention
• Industrial and Extended Temperature Ranges
• 8−pin PDIP, SOIC, MSOP, TSSOP, 8−pad UDFN, and WLCSP
6−ball Packages
• This Device is Pb−Free, Halogen Free/BFR Free, and RoHS

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