DS1216 SmartWatch RAM/SmartWatch ROM

Figure 2. Reset and Memory Density Options
The
RST pin on the controller has an internal pullup resistor. To disable the RST function, the trace
between pin 1 on the socket and pin 13 on the controller can be cut. In this case, the socket will ignore the
RST input, preventing address transitions from resetting the pattern match, even if the RST bit is enabled.
On the DS1216B and DS1216D, the two VCC pins are connected together on the PC board. The switched
VCC from the controller is connected to the two VCC pins that connect to the inserted RAM. No
modifications are required if the lower density RAM is used. To use the higher density RAM, the trace by
the lower density RAM VCC pin, identified by a hash mark labeled “U,” must be cut. The two square-
metal pads, labeled “G,” must be shorted together. This disconnects switched VCC from the pin going to
the inserted RAM, and connects it to the corresponding address input pin for the higher density RAM.
NOTE: THE LETTER SUFFIX OF THE SMARTWATCH IS LOCATED ON THE PC BOARD.
