This datasheet introduces the 8-Kbyte 128-Kbit EEPROM, including features, security features, smart card features, embedded application features, high reliability, etc.
The AT88SC12816C is a high‑performance secure memory from Atmel’s CryptoMemory® family, offering 128 Kbit (16 Kbyte) EEPROM user memory divided into sixteen 1‑Kbyte zones with programmable access rights. It supports ISO 7816 smart‑card protocols, a 2‑wire serial interface, and advanced cryptographic functions such as mutual authentication and stream encryption.
Key specifications include a supply voltage range of 2.7 V‑5.5 V, 1 MHz serial clock operation, 100 000 write‑cycle endurance, 10‑year data retention, and 4 000 V ESD protection. The device is supplied in standard 8‑lead plastic packages and is pin‑compatible with common 2‑wire serial EEPROMs.
