Name
Function
1TPOUT
Standard signal output (Nch open-drain output or CMOS output)
2
XOUT
Connects to the X’ftal resonator (f=32768 Hz)
3XIN
[Cg and Cd are built in]
4VSS
Power supply (GND)
5CS
Chip select input (Built-in pull-down resistance)
“H”:
The SIO pin is capable of inputting/outputting data.
The SCK pin is capable of accepting the input.
“L”:
The SIO pin is at Hi-Z.
The SCK pin is not capable of accepting the input.
6
SCK
Clock input:
Inputs and outputs data from the SIO pin in synchronization with the clock. The
clock cannot be accepted when the CS pin is “L.”
7
SIO
Serial data input/output:
When the CS is “L,” the SIO pin is at “Hi-Z.” When the CS pin changes from “L”
to “H,” it serves as the input pin. The SIO pin is assigned to the input or output pin
according to the next command data. The type of output is either Nch open-drain
or CMOS depending upon the model of the IC you use.
