CAT24C64BC4

CAT24C64BC4, CAT24C64BAC4 EEPROM Serial 64-Kb I2C in a 4-ball WLCSP Description The CAT24C64BC4 and CAT24C64BAC4 are EEPROM Serial 64−Kb I2C devices available in a 4−ball WLCSP package. Both devices are internally organized as 8192 words of 8 bits each. They feature a 32−byte page write buffer and support the Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I2C protocol. The CAT24C64BC4 and CAT24C64BAC4 respond to a different Slave Address and are therefore suitable in applications that require two serial EEPROM devices with 4−ball WLCSP on the same I2C bus. Features Supports Standard, Fast and Fast−Plus I2C Protocol 1.7 V to 5.5 V Supply Voltage Range 32−Byte Page Write Buffer 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 4−ball WLCSP Package This Device is Pb−Free, Halogen Free/BFR Free, and RoHS Compliant VCC SCL CAT24C64BC4 CAT24C64BAC4 SDA VSS Figure 1.
