Description
The DS1278Y-200 is a type of IC chip that falls into the nonvolatile SRAM category. It is a fully static, 16,777,216-bit component that is organized into 2,097,152 words by 8 bits. The design of the DS1278Y-200 includes a self-contained lithium energy source and control circuitry to constantly monitor VCC for out-of-tolerance conditions, with write protection being enabled automatically to prevent data corruption. The DS1278Y-200 has an unlimited number of write cycles, while no additional support circuitry is required for microprocessor interfacing. The lithium energy source is electronically disconnected to retain freshness until power is applied for the first time.
