7. FUNCTIONAL DESCRIPTION
7.1 General Description
W83L761G is a hardware monitoring IC with high temperature accuracy. W83L761G will be accessed
by SPI (Serial Peripheral Interface) interface. An 8-bit analog-to-digital converter (ADC) is built inside
W83L761G for monitored temperature converting. Shutdown mode is enabled by writing XXFF to
W83L761G, and will always output 800Fh.
7.2 Access Interface
W83L761G acts as a slave device on SPI compatible bus. CS# acts as the trigger of the W83L761G.
W83L761G would not response to the serial interface bus unless CS# acts low. SC is the serial clock
issued by the host. The data is received at the rising edge of the SC, and transmitted at the falling
edge of the SC.
There are three kinds of access types. Figure 1 shows the first access type, continuous reading 8-bit
frame from 761G. Here, “continuous” means the CS# does not de-asserted while reading out data. At
the end of last bit, host must output high on CS# to terminate the cycle. This access type is used to
readout W83L761G 8-bit temperature.
Figure 1 Continuous Reading 8 bit frame
The second access type is continuous reading 16-bit frame from W83L761G, and is illustrated in
figure 2. After first byte readout, host will not de-assert CS#, but will continue to send SC until next
byte is read out and then de-assert CS#.
