DATA SHEET www.onsemi.com 2 EEPROM Serial 16-Kb I C CAT24AA16 TSOT23 Description TB SUFFIX 2 The CAT24AA16 is a EEPROM Serial 16Kb I C device internally CASE 419AE organized as 2048x8 bits. The device features a 16byte page write buffer and supports 2 PIN CONFIGURATIONS 100 kHz, 400 kHz and 1 MHz I C protocols. Data is written by providing a starting address, then loading 1 to 16 TSOT23 contiguous bytes into a Page Write Buffer, and then writing all data to nonvolatile memory in one internal write cycle. Data is read by 5 SCL WP 1 providing a starting address and then shifting out data serially while V 2 automatically incrementing the internal address count.

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 pin is pulled down to GND internally. For improved noise immunity, the internal pull down 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
