Generic current sense configuration shown. Many circuit configurations using current and/or voltage
sensing are possible, including the use of shunts, transformers or Rogowski coils.
Power metering, with the measurement of active and reactive power, is done with the power metering
firmware application available through Microchip Technology.

1.5 Details on Individual Family
Members
Devices in the PIC18F87J72 family are available in
80-pin packages. Block diagrams for the two groups
are shown in Figure 1-1.
The devices are differentiated in that PIC18F86J72
devices have a Flash program memory of 64 Kbytes
and PIC18F87J72 devices memory is 128 Kbytes
All other features for the devices are identical. These
are summarized in Table 1-1.
The pinouts for all devices are listed in Table 1-2.
