Q & A
- What is the storage temperature range of the CAT24C128WIGT3JN?
The storage temperature range is −65°C to +150°C.
- What are the supported I2C protocol modes for this device?
The device supports Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C protocol modes.
- How does the hardware write protection work on this device?
The hardware write protection is achieved by taking the WP pin High, which protects the entire memory against write operations.
- What is the endurance of the CAT24C128WIGT3JN in terms of program/erase cycles?
The device has an endurance of 1,000,000 program/erase cycles.
- What is the data retention period of this device?
The data retention period is 100 years.
- Is the CAT24C128WIGT3JN RoHS compliant?
Yes, the device is Pb-Free, Halogen Free/BFR Free and RoHS compliant.
- What is the supply voltage range for this device?
The supply voltage range is from 1.8 V to 5.5 V.
- How many bytes can be written simultaneously during one internal write cycle?
Up to 64 bytes can be written simultaneously during one internal write cycle.
- What is the purpose of the Power-On Reset (POR) circuitry in the CAT24C128WIGT3JN?
The Power-On Reset (POR) circuitry protects the device against powering up in the wrong state and prevents 'brown-out' failure following a temporary loss of power.
- What are the typical current consumption values for read and write operations?
The read current is typically 1 mA at fSCL = 400 kHz/1 MHz, and the write current is typically 3 mA.
