Minimum order volume requirement. 6: This specification allows this device to be used in PIC microcontroller applications that require the In-Circuit Serial Programming (ICSP) feature (see device-specific programming specifications for voltage requirements). The total time that the RST pin can be above the maximum device operational voltage (5.5V) is 100s. Current into the RST pin should be limited to 2 mA. It is recommended that the device operational temperature be maintained between 0C to +70C (+25C preferred). For additional information, refer to Figure 2-41.
