NOTES:
1) IN THIS CONFIGURATION, THE VOLTAGE RANGE OF W 1 AND W 2 IS
3V-5V. THIS RANGE CAN BE EXTENDED USING EXTERNAL RESISTORS.
2) ONE MAX6156B CAN BE USED WITH MULTIPLE DS1870s.
See Figure 5 for a read example using the repeated
start condition to specify the starting memory location.
Reading multiple bytes from a slave: The read opera-
tion can be used to read multiple bytes with a single
transfer. When reading bytes from the slave, the master
simply ACKs the data byte if it desires to read another
byte before terminating the transaction. After the master
reads the last byte it NACKs to indicate the end of the
transfer and generates a stop condition. This can be
done with or without modifying the address counter’s
location before the read cycle. The DS1870’s address
counter does not wrap on page boundaries during read
operations, but the counter will roll from its upper most
memory address FFh to 00h if the last memory location
is read during the read transaction.
Application Information
Power-Supply Decoupling
To achieve best results, it is recommended that the power
supply is decoupled with a 0.01μF or a 0.1μF capacitor.
Use high-quality, ceramic, surface-mount capacitors, and
mount the capacitors as close as possible to the V CC and
GND pins to minimize lead inductance.
