93LC66A-E/SN Microchip

The 93LC66A-E/SN is a 4Kbit Serial Peripheral Interface (SPI) type Electrically Erasable Programmable Read-Only Memory (EEPROM), manufactured by Microchip and conforms to the RoHS (Restriction of Hazardous Substances) directive. It is a Small Outline Integrated Circuit (SOIC)-8 packaged device. This device features low-power CMOS technology, providing a typical active current of 200 µA and a standby current of 20 µA. Its eight-lead SOIC package is characterized by a wide voltage range of 2.7 to 5.5V, and the memory can store up to 4096 8-bit words. The device memory space can be divided into up to four sectors, making it suitable for code/data segregation in secure, automated systems. With write-protection, write/erase cycles of 100000 times and data retention up to 100 years, this memory is ideal for reliable data that needs long-term protection.
