Q & A
- What is the memory size of the CAT34C02VP2IGT4A?
The CAT34C02VP2IGT4A has a memory size of 2 Kb, organized as 16 pages of 16 bytes each. - What I2C protocols does the CAT34C02VP2IGT4A support?
The device supports both Standard (100 kHz) and Fast (400 kHz) I2C protocols. - What is the supply voltage range for the CAT34C02VP2IGT4A?
The supply voltage range is from 1.7 V to 5.5 V. - How does the write protection work on the CAT34C02VP2IGT4A?
The device features both hardware and software write protection. The WP pin can inhibit all write operations when pulled high, and software write protection can protect the lower half of the memory. - What is the data retention period for the CAT34C02VP2IGT4A?
The data retention period is 100 years. - How many program/erase cycles does the CAT34C02VP2IGT4A support?
The device supports up to 1,000,000 program/erase cycles. - What is the temperature range for the CAT34C02VP2IGT4A?
The industrial temperature range is from −40°C to +85°C. - What package type is the CAT34C02VP2IGT4A available in?
The device is available in an 8-TDFN (2x3) package. - Is the CAT34C02VP2IGT4A RoHS compliant?
Yes, the device is Pb-Free, Halogen Free/BFR Free and RoHS Compliant. - How does the Power-On Reset (POR) feature work?
The Power-On Reset circuitry protects the internal logic by ensuring the device powers up into Standby mode and powers down into Reset mode when the supply voltage drops below the POR trigger level.
