3 Applications Information
This section provides general usage information for the design and implementation of the 73S8010R.
3.1
Figure 4 shows a typical application schematic for the implementation of the 73S8010R. Note that minor changes may occur to the reference
material from time to time and the reader is encouraged to contact Teridian for the latest information
Rev. 1.6
NOTES:
1) VDD = 2.7V to 5.5V DC.
2) VPC = 4.75V(EMV, ISO) to 5.5V DC
3) Required if external clock from uP is used.
4) Required if crystal is used.
5) Optional. Can be left open.
6) R1 and R3 are external resistors that adjust the VDD
7) Hardware to define address of device
fault voltage. Can be left open.
Y1, C2 and C3 must be removed if external clock is used.
