The AT93C66A is a 4Kbit non-volatile EEPROM memory chip manufactured by Microchip Technology. It utilizes a standard 3-wire serial interface for communication, allowing for fast read and write access.
This EEPROM offers a memory organization of either 512 x 8 bits or 256 x 16 bits, providing flexibility for various data storage needs. It operates over a wide supply voltage range of 2.7V to 5.5V and functions reliably within an industrial temperature range of -40°C to 85°C.
The device is packaged in an 8-TSSOP (Thin Shrink Small Outline Package) suitable for surface mounting, making it ideal for space-constrained designs. The AT93C66A is designed for applications requiring robust data retention and endurance, such as industrial controls, metering, security systems, and general-purpose data storage.
Note: This part is obsolete and not recommended for new designs.
