CAT24AA01

CAT24AA01, CAT24AA02 EEPROM Serial 1/2-Kb I2C Description The CAT24AA01/24AA02 are EEPROM Serial 1/2−Kb I2C devices internally organized as 128x8/256x8 bits. They feature a 16−byte page write buffer and support the Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I2C protocols. In contrast to the CAT24C01/24C02, the CAT24AA01/24AA02 have no external address pins, and are therefore suitable in applications that require a single CAT24AA01/02 on the I2C bus. Features Supports Standard, Fast and Fast−Plus I2C Protocol 1.7 V to 5.5 V Supply Voltage Range 16−Byte Page Write Buffer Hardware Write Protection for Entire Memory Schmitt Triggers and Noise Suppression Filters on I2C Bus Inputs (SCL and SDA) Low Power CMOS Technology 1,000,000 Program/Erase Cycles 100 Year Data Retention Industrial Temperature Range These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant VCC SCL CAT24AA01 CAT24AA02 WP SDA VSS Figure 1.
