2.5.1
The MCP9800 comes with user-programmable registers that provide flexibility for tem-
perature-sensing applications. The register settings allow user-selectable 9-bit to 12-bit
temperature measurement resolution, configuration of the power-saving Shutdown and
One-Shot (single conversion on command while in Shutdown) modes and the specifi-
cation of both temperature alert output and hysteresis limits. When the temperature
changes beyond the specified limits, the MCP9800 outputs an alert signal. The user
has the option of setting the alert output signal polarity as an active-low or active-high
comparator output for thermostat operation, or as a temperature event interrupt output
for microprocessor-based systems.
This device has I
sheet (DS21909) for further details).
2.5.2
The 24LC16B is a 16 Kbit Electrically Erasable PROM. This device has
I
1.8V with standby and active currents of only 1μa and 1mA, respectively. The device
also has a page write capability for up to 16 bytes of data.
2.5.3
The MCP101 is a voltage supervisory device designed to keep a microcontroller in
Reset until the system voltage has reached the proper level and stabilized. It also
operates as protection from brown-out conditions when the supply voltage drops below
a safe operating level.
