Applications
The PIC18F57Q84T-I/PT is designed for automotive body electronics, industrial motor drives, and building automation controllers that require CAN FD networking alongside precise analog measurement. Its DMA engine off-loads data movement between peripherals, allowing the 64 MHz CPU to focus on control algorithms such as FOC motor loops or CANopen protocol stacks. Multi-voltage operation from 2.5 V to 5 V simplifies integration in mixed-voltage automotive ECUs and industrial PLCs.

Frequently Asked Questions
How does the CAN FD peripheral in the PIC18F57Q84T-I/PT differ from classical CAN and at what data rate does it operate?
The PIC18F57Q84T-I/PT's CAN FD controller supports arbitration at 1 Mbit/s and data-phase speeds up to 8 Mbit/s, compared to classical CAN limited to 1 Mbit/s end-to-end. The extended payload of up to 64 bytes per frame versus the classical 8 bytes lets an automotive body control module transfer a full sensor snapshot in a single CAN FD frame, reducing latency and bus utilization in networked ECU designs.
What ADC resolution and how many input channels does the PIC18F57Q84T-I/PT provide for sensor acquisition?
The PIC18F57Q84T-I/PT integrates a 12-bit ADC with up to 35 selectable input channels and a hardware accumulator that sums 256 samples in hardware, enabling oversampling to approximately 16-bit effective resolution without CPU overhead. At 64 MHz, sampling rates up to 500 ksps per channel support simultaneous acquisition of temperature, pressure, and current-sense signals in a multi-axis motor control or industrial monitoring application.
How does the DMA controller in the PIC18F57Q84T-I/PT improve real-time performance versus a PIC18 without DMA?
The DMA controller transfers data between SPI, UART, ADC, and memory at up to 64 MHz bus speed independently of the CPU, keeping the 8-bit core free for time-critical tasks such as PID loops running at 10 kHz update rates. Without DMA, a PIC18 CPU servicing a 4 Mbit/s SPI data stream at 512 bytes per transaction would consume approximately 40% of its cycles on data movement, leaving only 60% for application logic.
Which supply voltage options does the PIC18F57Q84T-I/PT support and what does this mean for automotive 3.3 V ECU integration?
The PIC18F57Q84T-I/PT operates from 2.5 V to 5.5 V across -40°C to 85°C, making it natively compatible with 3.3 V automotive microcontroller domains as well as legacy 5 V sensor and actuator interfaces. In a 3.3 V ECU, the device runs at full 64 MHz speed with no derating, and its 5 V-tolerant I/O pins can directly interface 5 V legacy sensors without level-shifting resistors, reducing component count in body control module designs.
For a compact motor-control board, how much PCB area does the 48-pin TQFP package occupy and what is its pin pitch?
The 48-pin TQFP package measures 7 mm × 7 mm with a 0.5 mm pin pitch, occupying 49 mm² of PCB land area. This compact footprint fits within a standard 10 mm × 10 mm IC placement zone on a 2-layer PCB, leaving room for gate drivers and current-sense resistors on a 50 mm × 50 mm motor-control daughterboard, while the 48 pins provide enough GPIO for encoder, SPI, CAN FD, and PWM outputs simultaneously.
