Key Features
- 64 MHz maximum clock speed with internal oscillator up to 16 MHz provides high computation throughput for PIC18 8-bit applications without an external crystal
- 3968 bytes of RAM and 8 KB self-programmable flash deliver sufficient data buffering and code storage for medium-complexity embedded firmware
- 2.3 V minimum supply at 20 MHz enables low-voltage battery operation while the 44-pin TQFP package exposes a full complement of GPIO, ADC, SPI, I2C, and UART peripherals
Applications
The PIC18F43K22-I/PT is used in industrial sensor interfaces, HVAC controllers, and building automation nodes where the 44-pin TQFP package provides ample I/O for multi-channel ADC acquisition and serial communication. Its wide supply range from 2.3 V to 5.5 V makes it suitable for both 3.3 V and 5 V system designs, covering battery-backed sensors as well as direct 5 V microcontroller boards. The 64 MHz maximum clock and rich peripheral set support real-time control tasks such as PID loops and protocol bridging in compact embedded modules.

Frequently Asked Questions
What is the maximum clock speed and minimum supply voltage of the PIC18F43K22-I/PT?
The PIC18F43K22-I/PT runs at a maximum clock frequency of 64 MHz when the supply voltage is at the upper end of the 2.3 V to 5.5 V operating range. At the minimum supply of 2.3 V, the clock is limited to 20 MHz. This graduated clock-voltage relationship allows designers to trade off processing speed against supply voltage to suit 3.3 V or 5 V system rails.
How much memory does the PIC18F43K22-I/PT provide for data buffering and program storage?
The PIC18F43K22-I/PT integrates 8 KB of self-programmable flash for program memory and 3968 bytes of SRAM for data storage. This is sufficient for medium-complexity firmware including multi-axis PID controllers, serial protocol stacks, and lookup tables, without requiring external memory for most embedded control applications in the 8-bit PIC18 family.
Which analog and serial peripherals does the PIC18F43K22-I/PT integrate for sensor interfacing?
The PIC18F43K22-I/PT includes a 10-bit ADC with multiple input channels, along with SPI, I2C, and multiple UART modules for serial communication. These peripherals allow the MCU to read analog sensor voltages at 10-bit resolution, communicate with digital sensors over I2C or SPI, and transmit data to a host system via UART, all within a single 44-pin TQFP device.
When is the PIC18F43K22-I/PT preferable to smaller 28-pin PIC18 variants for a motor or HVAC control board?
The PIC18F43K22-I/PT in the 44-pin TQFP package exposes significantly more GPIO pins than 28-pin alternatives, enabling simultaneous connection of multiple ADC channels, PWM outputs for motor drive signals, and serial interfaces for display or sensor modules. If a design requires more than 20 I/O lines, a 10-bit ADC with at least 8 channels, and dual UART for multi-bus communication, the 44-pin TQFP becomes the correct choice over compact 28-pin SSOP or DIP packages.
