Applications
The PIC18F87J94-I/PT is designed for smart energy meters, industrial data loggers, and building automation controllers that require a high-I/O-count 8-bit MCU with fast 64 MHz execution and large 128 KB Flash for firmware complexity. Its 80-pin TQFP package provides ample GPIO for driving display segments, reading multiple sensor inputs, and communicating over serial interfaces simultaneously. Power quality monitors and programmable logic controllers (PLCs) leverage its ADC and broad peripheral mix to acquire and process electrical signals with firmware-defined algorithms.

Frequently Asked Questions
What are the Flash memory size and clock speed of PIC18F87J94-I/PT and how do they support complex firmware?
PIC18F87J94-I/PT provides 128 KB of Flash program memory with a 64 MHz maximum clock frequency, delivering up to 16 MIPS instruction throughput. This combination accommodates sophisticated firmware including communication stacks, metering algorithms, and multi-protocol serial handling in a single 8-bit PIC18 device, eliminating the need for an external code storage chip in energy meter and industrial controller designs.
How does the 80-pin TQFP package of PIC18F87J94-I/PT benefit complex sensor and display interface designs?
The 80-pin TQFP package measures approximately 12 mm x 12 mm with 0.5 mm pin pitch, providing up to 66 general-purpose I/O pins after assigning power and ground. This high pin count allows simultaneous connection of LCD segment drivers (requiring 40 to 60 output lines), multiple analog sensor inputs via 12-bit ADC channels, and serial interfaces (SPI, I2C, UART) in smart meter and industrial HMI designs without external I/O expanders.
For a 3-phase energy meter design, what built-in capabilities does PIC18F87J94-I/PT offer for electrical measurement?
PIC18F87J94-I/PT's integrated multi-channel 12-bit ADC can sample all 3 phase voltages and 3 phase currents simultaneously through multiple input channels, enabling real-time power factor and RMS calculation at 64 MHz. The 20-bit address bus supports access to large lookup tables and calibration coefficients stored in 128 KB Flash, while multiple UART channels communicate meter readings to AMI networks at baud rates up to 115200 bps.
When should a designer choose PIC18F87J94-I/PT over a lower-pin-count PIC18 such as PIC18F45K22 for an industrial application?
PIC18F87J94-I/PT's 80-pin TQFP is the right choice when I/O count exceeds 35 pins and Flash code size exceeds 32 KB — both limits of smaller PIC18F45K22 (44-pin, 32 KB Flash). Industrial data loggers reading 20 or more analog sensor channels and driving LCD modules simultaneously require the additional 40+ GPIO pins that only the 80-pin package provides, while the larger 128 KB Flash accommodates full communication stack plus application code in one device.
