The AT93C66A-10SU-2.7 from ATM is a 2K/4K bit serial electrically erasable programmable read-only memory (EEPROM). It is optimized for industrial and commercial applications requiring low-power and low-voltage operation, supporting a wide voltage range from 1.8V to 5.5V. The device features a user-selectable internal organization of either 256x8 or 128x16 bits for 2K capacity, and 512x8 or 256x16 bits for 4K capacity.
This EEPROM utilizes a three-wire serial interface consisting of Chip Select (CS), Data Input (DI), Data Output (DO), and Shift Clock (SK). It supports sequential read operations and has a clock rate of up to 2 MHz at 5V. The write cycle is self-timed, with a maximum duration of 10 ms, and is enabled only in the Erase/Write Enable State. The device boasts high reliability with an endurance of 1 million write cycles and data retention for up to 100 years.
The AT93C66A-10SU-2.7 is available in various 8-lead packages, including JEDEC PDIP, JEDEC SOIC, EIAJ SOIC, Ultra Thin mini-MAP (MLP 2x3), Ultra Lead Frame Land Grid Array (ULA), TSSOP, and dBGA2. Its operating temperature range is -55°C to +125°C, making it suitable for demanding environments.
