Working Principle

The AT93C66AY1-10YI-1.8 is organized into two blocks: an array of 32K (2K x 16) bits of memory, and an array of 6 x 16K bits of permanent security bits, which can be programmed only once. The high-density memory array of the AT93C66AY1-10YI-1.8 is divided into pages of 64 bytes each, and they can be accessed individually. The memory array data is non-volatile and can be read or written by using a 5-wire or 3-wire SPIE bus.The AT93C66AY1-10YI-1.8 memory is organized block by block. The array is divided into 16 blocks of 2K x 16 bits each and arranged in a 16 x 2K organization. The user can access the individual blocks separately by addressing the block, and they can also be read or written as a single block. The memory array consists of 65,536 individual memory cells, 8-bits wide. The user can access the data bytes by addressing the byte location. Block write and byte write operations are provided for the data byte writing. These features make the AT93C66AY1-10YI-1.8 memory very suitable for storing data and maintaining information over long periods of time.AT93C66AY1-10YI-1.8 has a low voltage operation, which is 25V for read/write operations, and it has exceptional data retention characteristics at reduced temperatures. The endurance of the device is guaranteed to be greater than 40,000 write cycles and the operating temperature range is between -40°C to +85°C. AT93C66AY1-10YI-1.8 memory IC is an ideal solution for applications that require non-volatile memory storage with low power consumption. It has high speed and reliable operation, which makes it suitable for use in wide range of applications.
