DS1216

NOTES:
1. All voltages are referenced to ground.
2. Measured with a load as shown in Figure 3.
3. Pin locations are designated “U” when a parameter definition refers to the socket receptacle and “L”
when a parameter definition refers to the socket pin.
4. No memory inserted in the socket.
5. Pin 26L can be connected to VCC or left disconnected at the PC board.
6. SmartWatch sockets can be successfully processed through some conventional wave–soldering
techniques as long as temperature exposure to the lithium energy source contained within does not
exceed +85
°C. However, post solder cleaning with water washing techniques is not permissible.
Discharge to the lithium energy source may result, even if de-ionized water is utilized. It is equally
imperative that ultrasonic vibration is not used in order to avert damage to the quartz crystal resonator
employed by the oscillator circuit.
7. tCE max. must be met to ensure data integrity on power loss.
8. VCC is within nominal limits and a memory is installed in the socket.
9. Input pulse rise and fall times equal 10 ns.
10. Applies to Pins 1 L, 11 L, 20 L, 22 L, and 27 L.
11. tWR is a functions of the latter occurring edge of WE or CE .
12. tDH and tDS are a function of the first occurring edge of WE or CE .
13. RST (Pin 1) has an internal pull–up resistor.
14. Total battery capacity is used to determine the expected lifetime of a DS1216 in battery back mode.
The user should determine the Standby Current of the selected RAM and calculate the expected
lifetime. The maximum (Ibmax) current draw from the DS1216 is 10 ua.
15. The DS1216 products are shipped with backup battery power off. First power up switches backup
battery on to clock and RAM Vcc pin upon power down.
