DescriptionThe DS1216D SmartWatch/RAM 256K/1M is a 32pin, 600-mil wide DIP socket with a builtin CMOS watch function, a nonvolatile RAM controller circuit, and an embedded lithium energy source. DS1216D accepts either an 8K x 8, 32K x 8, 128K x 8, or 512K x 8 JEDEC bytewide CMOS static RAM. When the socket is mated with a CMOS SRAM,DS1216D provides a complete solution to problems associated with memory volatility and uses a common energy source to maintain time and date. A key feature of the DS1216D is that the watch function remains transparent to the RAM.
See the DS1216B SmartWatch/RAM 16/64K data sheet for technical details.
