Frequently Asked Questions
What supply voltage range does the AT88SC0104CA-SU support, and how does it affect compatibility with 3.3 V and 5 V systems?
The AT88SC0104CA-SU operates from 2.7 V to 5.5 V, making it compatible with both 3.3 V and 5 V logic systems without a level shifter. This wide range simplifies integration in mixed-voltage designs. The I2C bus speed is supported up to 1 MHz within this voltage window.
How much data can the AT88SC0104CA-SU store, and is it sufficient for storing cryptographic keys and certificates?
The device provides 1 Kbit (128 bytes) of EEPROM storage. This capacity is sufficient to store small cryptographic keys such as 64-bit or 128-bit secret keys, configuration data, and authentication credentials in typical embedded security applications requiring protected memory up to 128 bytes.
For an industrial IoT gateway operating from -40°C to +85°C, is the AT88SC0104CA-SU rated for that environment?
Yes, the AT88SC0104CA-SU is rated for the full industrial temperature range of -40°C to +85°C, making it suitable for outdoor gateways, factory automation nodes, and harsh-environment embedded systems. The SOIC-8 package also supports standard wave or reflow soldering for production assembly.
