DESCRIPTION

The CAT93C46/56/57/66/86 are 1K/2K/2K/4K/16K-bit Serial E 2PROM memory devices which are 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 CAT93C46/56/ 57/66/86 are manufactured using Catalyst’s advanced 93C46/56/57/66/86 F01 PIN FUNCTIONS Pin Name Function CS Chip Select SK Clock Input DI Serial Data Input DO Serial Data Output VCC +1.8 to 6.0V Power Supply GND Ground ORG Memory Organization NC No Connection PE* Program Enable BLOCK DIAGRAM Note: When the ORG pin is connected to VCC, the X16 organiza tion 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. © 1998 by Catalyst Semiconductor, Inc.

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. RELIABILITY CHARACTERISTICS Symbol Parameter Min. Max.

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 up to 100 mA on address and data pins from –1V to V CC +1V. (5) Standby Current (ISB2)=0µA (<900nA) for 93C46/56/57/66, (ISB2)=2µA for 93C86. D.C.
