1 / 16 page © Semiconductor Components Industries, LLC, 2012 April, 2012 − Rev. 11 1 Publication Order Number: CAT93C66/D CAT93C66, CAT93W66 4 kb Microwire Serial CMOS EEPROM Description The CAT93C66 is a 4 kb CMOS Serial EEPROM device which is organized as either 256 registers of 16 bits (ORG pin at VCC) or 512 registers of 8 bits (ORG pin at GND). The CAT93W66 features x16 memory organization only. Each register can be written (or read) serially by using the DI (or DO) pin. The device features sequential read and self−timed internal write with auto−clear. On−chip Power−On Reset circuitry 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 to 5.5 V Supply Voltage Range • Selectable x8 or x16 Memory Organization: CAT93C66 • Self−timed Write Cycle with Auto−clear • Sequential Read • Software Write Protection • Power−up Inadvertent Write Protection • Low Power CMOS Technology • 1,000,000 Program/Erase Cycles • 100 Year Data Retention • Industrial and Extended Temperature Ranges • 8−lead PDIP, SOIC, TSSOP, 6−lead SOT−23, 8−pad TDFN and UDFN Packages • These Devices are Pb−Free, Halogen Free/BFR Free, and RoHS Compliant ORG DO CAT93C66 SK GND VCC Figure 1. Functional Symbols DI CS DO CAT93W66 SK GND VCC DI CS CAT93C66 Selectable Organization: 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 pull−up device will select the x16 organization. CAT93W66: The device works in x16 mode only. http://onsemi.com PIN CONFIGURATION DO DI SK CS See detailed ordering and shipping information in the package dimensions section on page 16 of this data sheet.
