Effect of Temperature on Time-Out

Period (tRPU)

The time-out period (t

RPU) determines how long the

device remains in the reset condition. This is affected

by both V

DD and temperature. The graph shown in

Figures 2-22, 2-23 and 2-24 show the typical response

for different V

DD values and temperatures.

Using in PIC® Microcontroller

ICSP™ Applications (MCP111

only)

Figure 4-4 shows the typical application circuit for using

the MCP111 for voltage supervisory function when the

PIC microcontroller will be programmed via the In-Cir-

cuit Serial Programming™ (ICSP) feature. Additional

information is available in TB087, “Using Voltage

Supervisors with PIC® Microcontroller Systems which

Implement

In-Circuit

Serial

Programming™”,

DS91087.
