Description

The 93LC66A-I/SN is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) device manufactured by Microchip Technology. It features 1024 bits of memory organized in 128 words of 8 bits each. The device operates using a 3.0V to 5.5V supply voltage and communicates via a serial interface, adhering to the SPI (Serial Peripheral Interface) protocol.
Key features include:
- Memory Density: 1024 bits (128 x 8 bits).
- Access Time: Fast read times, typically around 200 ns.
- Endurance: Supports a high number of write/erase cycles, usually around 1 million cycles per memory cell.
- Data Retention: Retains data for over 100 years under proper conditions.
- Low Power Consumption: Ideal for battery-operated devices due to low standby and active current requirements.
