The a 16K-bit Serial EEPROM memory device which is configured as either registers of 16 bits (ORG pin at VCC) or 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The CAT93C86 is manufactured using Catalyst's advanced CMOS EEPROM floating gate technology. The device is designed to endure 1,000,000 program/erase cycles and has a data retention of 100 years. The device is available in 8-pin DIP, 8-pin SOIC and 8-pad TDFN packages.

Pin Name CS Function Chip Select Clock Input Serial Data Input Serial Data Output Power Supply Ground Memory Organization Program Enable

Note: When the ORG pin is connected to VCC, 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 pullup device will select the x16 organization.

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.

Note: (1) The minimum DC input voltage is �0.5V. During transitions, inputs may undershoot to �2.0V for periods of less than 20 ns. Maximum DC voltage on output pins is VCC +0.5V, which may overshoot to VCC +2.0V for periods of less than 20 ns. (2) Output shorted for no more than one second. No more than one output shorted at a time. (3) This parameter is tested initially and after a design or process change that affects the parameter. (4) Latch-up protection is provided for stresses mA on address and data pins from �1V to VCC +1V.
