Description
The CAT24C32BC4 and CAT24C32BAC4 are EEPROM Serial 32−Kb I2C devices available in a 4−ball WLCSP package. Both devices are internally organized as 4096 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 CAT24C32BC4 and CAT24C32BAC4 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.
