CAT24C32BC4,
CAT24C32BAC4
EEPROM Serial 32-Kb I2C
in a 4-ball WLCSP
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.
Features
• Supports Standard, Fast and Fast−Plus I2C Protocol
• 1.7 V to 5.5 V Supply Voltage Range
• 32−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
• 4−ball WLCSP Package
• This Device is Pb−Free, Halogen Free/BFR Free, and RoHS
Compliant
