Using in PICmicro®

Microcontroller, ICSP™

Applications (MCP121 only)

Figure 4-5 shows the typical application circuit for using

the MCP121 for voltage superviory function when the

PICmicro microcontroller will be programmed via the

ICSP feature. Additional information is available in

TB087, “Using Voltage Supervisors with PICmicro®

Microcontroller Systems which Implement In-Circuit

Serial Programming™”, DS91087.

Typical Application Circuit

for PICmicro® Microcontroller with the ICSP™

feature.

Note:

It is recommended that the current into the

RST pin be current limited by a 1 k

resistor.
