Product Overview
The 93LC66A-I/SN is a 4kB MICROWIRE compatible serial Electrically Erasable Programmable Read-Only Memory (EEPROM) with word-selectable devices. The 93AA66A device provides dedicated 16-bit communication. Advanced CMOS technology makes this device ideal for low power, non-volatile memory applications.
- Low-power CMOS technology
- Self-timed erase and write cycles
- Automatic ERAL before WRAL
- Power ON/OFF data protection circuitry
- Industry standard 3-wire serial I/O
- Device status signal
- Sequential read function
- 1000000 Erase/write cycles ensured
- Data retention <gt/>200 years
Applications
Computers & Computer Peripherals, Industrial, Communications & Networking, Consumer Electronics, Automotive
