Description

The DS1216H SmartWatch/RAM 4M 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. DS1216H accepts 512K x 8 JEDEC bytewide CMOS static RAM. When the socket is mated with a CMOS SRAM, DS1216H 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 DS1216H is that the watch function remains transparent to the RAM.

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