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.
Note:
It is recommended that the current into the
RST pin be current limited by a 1 kΩ
resistor.
