NOTES:
1. All voltages are referenced to ground.
2. Measured with a load shown in Figure 3.
3. Pin locations are designated “U” when a parameter definition refers to the socket receptacle and “L” when a pa-
rameter definition refers to the socket pin.
4. No memory inserted in the socket.
5. Input pulse rise and fall times equal 10 ns.
6. Applies to pins 1 L, 8 L, 10 L, 20 L, and 22 L.
7. t
WR
and t
RR
are functions of the first occurring edge of OE or CE.
8. t
AH
, t
DS
, and t
DH
are functions of the first occurring edge of OE or CE.
9. t
AS
is a function of the latter occurring edge of OE or CE.
10.RST (Pin 1) has an internal pull–up resistor.
11. 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.
