Applications
The PIC18F4220-I/PT is suited for industrial control panels, motor drive interfaces, and data acquisition systems that require a higher-performance 8-bit MCU with ample I/O and analog capability. Its 40 MHz clock and 36 I/O pins support simultaneous management of multiple peripherals including SPI, I2C, UART, and PWM outputs. The 2V minimum supply voltage also enables battery-operated field instruments and portable devices that share a common firmware base with 5V lab equipment.

Frequently Asked Questions
What is the maximum operating frequency of PIC18F4220-I/PT and what supply voltage is required to reach it?
The PIC18F4220-I/PT achieves its maximum clock frequency of 40 MHz when supplied from 4.2V to 5.5V. At lower supply voltages such as 2V, the device is limited to 4 MHz to ensure reliable operation. This frequency-voltage scaling allows low-power designs to trade throughput for reduced power consumption.
How many ADC input channels does PIC18F4220-I/PT offer and what is the converter resolution?
The PIC18F4220-I/PT includes a 10-bit successive-approximation ADC with up to 13 multiplexed analog input channels. This allows measurement of multiple sensors such as thermistors, pressure transducers, and potentiometers in a single device, achieving a resolution of approximately 4.88 mV per LSB on a 5V reference.
In which motor control or power electronics designs does PIC18F4220-I/PT deliver a useful combination of PWM outputs and ADC?
PIC18F4220-I/PT suits brushed DC motor speed controllers and single-phase inverter designs where 2 to 4 PWM channels at up to 20 MHz timer clock need to be coordinated with 10-bit ADC current and voltage feedback. The 44-TQFP package gives access to all 36 I/O pins, supporting gate-drive signals, fault inputs, and serial diagnostic interfaces on a single device.
How does the PIC18F4220-I/PT TQFP-44 package compare to the DIP-40 package option for board layout purposes?
The 44-TQFP package measures 10 mm x 10 mm with 0.8 mm lead pitch, occupying less than one-quarter of the footprint of a 600-mil DIP-40 package. This compact size enables denser PCB layouts with shorter signal traces, reduced parasitic inductance on high-speed I/O lines, and compatibility with automated SMT assembly for production volumes.
