CAT24C64C4CTR

2 64 Kb I C CMOS Serial EEPROM CAT24C64 Description The CAT24C64 is a 64 Kb CMOS Serial EEPROM device, www.onsemi.com internally organized as 8192 words of 8 bits each. It features a 32byte page write buffer and supports the Standard 2 (100 kHz), Fast (400 kHz) and FastPlus (1 MHz) I C protocol. External address pins make it possible to address up to eight CAT24C64 devices on the same bus.

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 2.

These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AECQ100 and JEDEC test methods. 5. When not driven, the WP, A0, A1 and A2 pins are pulled down to GND internally. For improved noise immunity, the internal pulldown is relatively strong therefore the external driver must be able to supply the pulldown current when attempting to drive the input HIGH. To conserve power, as the input level exceeds the trip point of the CMOS input buffer (~ 0.5 x V ), the strong pulldown reverts to a weak current source. CC www.onsemi.com 2
