N24S128 2 128 Kb I C CMOS Serial EEPROM with Software Write Protect and Programmable Device www.onsemi.com Address Description The N24S128 is a 128Kb Serial CMOS EEPROM, internally organized as 816,384 words of 8 bits each. WLCSP4 C4 SUFFIX They feature a 64-byte page write buffer and support both the CASE 567VY 2 Standard (100kHz), Fast (400kHz) and Fast-Plus (1MHz) I C protocol. PIN CONFIGURATION The devices also feature a 128-bit factory-set read-only Unique ID, a 64-byte Secure Data Page that can be permanently locked against 12 future changes, and Software Write Protection of the entire array. A V SCL CC A Device Configuration Register enables the user to specify the last 3 bits of the Device Address, allowing up to eight N24S128 devices to be addressed on the same bus.

ABSOLUTE MAXIMUM RATINGS Parameter Rating Unit 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 + 1.0 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.
