AT93C66A-10SU-2.7 Description

Short technical summary and product information.

The AT93C66A-10SU-2.7 from Atmel is a 4Kb serial electrically erasable programmable read-only memory (EEPROM). It offers user-selectable internal organization, allowing for either 512 x 8 bits or 256 x 16 bits configurations, controlled by the ORG pin. This device is optimized for industrial and commercial applications requiring low-power and low-voltage operation, supporting voltage ranges from 1.8V to 5.5V and 2.7V to 5.5V.

Featuring a three-wire serial interface (Chip Select, Data Input, Data Output, and Shift Clock), the AT93C66A-10SU-2.7 allows for sequential read operations and has a maximum clock rate of 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.

Available in various 8-lead packages including PDIP, SOIC, TSSOP, and others, this EEPROM is suitable for a wide range of embedded systems. Its automotive devices are also available, indicating suitability for demanding environments. The operating temperature range is from -55°C to +125°C, with storage temperatures from -65°C to +150°C.
