  Connection Diagram


The DS1216C SmartWatch/RAM is a 28pin, 600-mil wide DIP socket with a builtin CMOS watch function, a nonvolatile RAM controller circuit, and an embedded lithium energy source. DS1216C accepts either an 8K x 8 or a 32K x 8 JEDEC bytewide CMOS static RAM. When the socket is mated with a CMOS SRAM, DS1216C 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 DS1216C is that the watch function remains transparent to the RAM.

See the DS1216B SmartWatch/RAM 16/64K data sheet for technical details.
