CAS93C66VP2 4 Kb Microwire Serial CMOS EEPROM Description The CAS93C66VP2 is a 4 kb CMOS Serial EEPROM device which is organized as either 256 registers of 16 bits (ORG pin at V ) or 512 CC www.onsemi.com registers of 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The device features sequential read and selftimed internal write with autoclear. Onchip PowerOn Reset circuitry protects the internal logic against powering up in the wrong state.

V CC ORG CS CAS93C66VP2 DO SK DI GND Figure 1. Functional Symbol CAS93C66VP2 Selectable Organization: When the ORG pin is connected to V , the x16 organization is CC 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.

ABSOLUTE MAXIMUM RATINGS Parameters Ratings Units Storage Temperature 65 to +150 C Voltage on Any Pin with Respect to Ground (Note 1) 0.5 to +6.5 V Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. The DC input voltage on any pin should not be lower than 0.5 V or higher than V + 0.5 V. During transitions, the voltage on any pin may CC undershoot to no less than 1.5 V or overshoot to no more than V + 1.5 V, for periods of less than 20 ns. CC Table 3.
