CAT25128 128-Kb SPI Serial CMOS EEPROM Description The CAT25128 is a 128Kb Serial CMOS EEPROM device internally organized as 16Kx8 bits. This features a 64byte page write CAT25128 Table 1. ABSOLUTE MAXIMUM RATINGS Parameters Ratings Units Operating Temperature 45 to +130 C 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. RELIABILITY CHARACTERISTICS (Note 2) Symbol Parameter Min Units N (Notes 3, 4) Endurance 1,000,000 Program / Erase Cycles END T Data Retention 100 Years DR 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. Page Mode, V = 5 V, 25C. CC 4. The new product revision (E) 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 reprogrammed. 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.
