Q & A
- What is the memory size of the CAT24C64C4CTR?
The memory size is 64 Kb, organized as 8192 words of 8 bits each.
- What are the supported I2C protocols?
The device supports Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C protocols.
- What is the supply voltage range for the CAT24C64C4CTR?
The supply voltage range is from 1.7 V to 5.5 V.
- How many program/erase cycles does the device support?
The device supports 1,000,000 program/erase cycles.
- What is the data retention period of the CAT24C64C4CTR?
The data retention period is 100 years.
- What is the temperature range for the industrial version of the CAT24C64C4CTR?
The temperature range is from −40°C to +85°C.
- What package type is the CAT24C64C4CTR available in?
The device is available in a WLCSP-4 package.
- Is the CAT24C64C4CTR Pb-free and RoHS compliant?
- How does the hardware write protection work on the CAT24C64C4CTR?
When the WP pin is held HIGH, the entire memory is protected against write operations. If the WP pin is left floating or grounded, it has no impact on the write operation.
- What is the purpose of the Power-On Reset (POR) circuitry in the CAT24C64C4CTR?
The Power-On Reset (POR) circuitry protects the internal logic against powering up in the wrong state and ensures the device powers up into Standby mode after VCC exceeds the POR trigger level.
