CAT24M01 2 EEPROM Serial 1-Mb I C Description 2 The CAT24M01 is a EEPROM Serial 1Mb I C, internally organized as 131,072 words of 8 bits each. It features a 256byte page write buffer and supports the Standard 2 (100 kHz), Fast (400 kHz) and FastPlus (1 MHz) I C protocol. www.onsemi.com Write operations can be inhibited by taking the WP pin High (this protects the entire memory). External address pins make it possible to address up to four CAT24M01 devices on the same bus. OnChip ECC (Error Correction Code) makes the device suitable SOIC8 UDFN8 SOIC8 for high reliability applications.

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. 3. Test Condition: Page Mode, V = 5 V, 25C. CC 4. The device uses ECC (Error Correction Code) logic with 6 ECC bits to correct one bit error in 4 data bytes. Therefore, when a single byte has to be written, 4 bytes (including the ECC bits) are re-programmed. It is recommended to write by multiple of 4 bytes in order to benefit from the maximum number of write cycles. Table 3. D.C.
