Descriptions:

• The CAT22C10L-20 is a low-power, byte-erasable EEPROM designed for non-volatile data storage.
• It supports byte write and page write operations.
• Features a three-wire control interface (Chip Enable, Output Enable, and Write Enable).
• Compatible with standard microprocessor and microcontroller systems.

Features:

• Low Power Consumption: Active current (Icc) of 10 mA (max), standby current of 100 µA (max).
• High Reliability: Built-in error detection and correction.
• Automatic Page Write: Allows writing up to 8 bytes in a single cycle.
• Hardware & Software Data Protection: Prevents accidental writes.
• Industry-Standard Pinout: Compatible with other 256-byte EEPROMs.
• RoHS Compliant: Lead-free and environmentally friendly.

This EEPROM is commonly used in applications requiring small, non-volatile memory storage, such as configuration settings, calibration data, and parameter storage in embedded systems.
