- Integrated 12-bit ADC with computation (ADCC) and on-chip DAC channels eliminate external analog components for closed-loop sensing designs
- Multiple serial interfaces (UART, SPI, I2C) enable simultaneous connectivity to sensors, displays, and host processors on a single 44-pin TQFP chip
- YTEOL of 19 years confirms long-term production availability, making PIC18F47K42-I/PT suitable for industrial and medical products with decade-long supply commitments
Applications
The PIC18F47K42-I/PT is well suited for embedded control applications such as smart sensor nodes, industrial I/O controllers, and home automation hubs that benefit from 8-bit simplicity paired with advanced analog peripherals. Its integrated 12-bit ADC with computation hardware offloads averaging, oversampling, and threshold detection from the CPU, making it ideal for battery-operated environmental monitoring devices. The 44-pin TQFP package and 64 MHz clock also make it a strong choice for driving small LCD modules, UART data loggers, and motor speed regulators in consumer appliances.

Frequently Asked Questions
What ADC resolution and computation features does PIC18F47K42-I/PT provide for precision sensor measurement?
The PIC18F47K42-I/PT integrates a 12-bit ADC with Computation (ADCC) module that supports hardware averaging, burst averaging, and low-pass filter accumulation modes without CPU intervention. The ADCC can oversample up to 256 samples to effectively achieve 17-bit resolution for slow-moving sensor signals such as temperature or pressure. Multiple analog input channels allow simultaneous connection of several sensors, making it suitable for multi-channel data acquisition front-ends operating from a 1.8 V to 5.5 V supply.
For a small motor speed controller, how does PIC18F47K42-I/PT's 64 MHz clock help maintain tight control loop timing?
At 64 MHz with a 4-stage pipeline, the PIC18F47K42-I/PT executes up to 16 million instructions per second (16 MIPS), which is sufficient for PID control loops running at 10 kHz sample rates with headroom for UART communication and ADC conversion. The CCP (Capture Compare PWM) modules generate PWM signals from DC to several hundred kHz to drive gate drivers for brushed DC or stepper motor H-bridges. Hardware timers with 16-bit resolution provide precise period and duty cycle control without software overhead.
Which serial communication interfaces are available on PIC18F47K42-I/PT and how many can be used simultaneously?
The PIC18F47K42-I/PT provides multiple Universal Asynchronous/Synchronous Receiver Transmitters (EUSART), SPI, and I2C master/slave interfaces, all of which can operate independently and simultaneously through the Peripheral Pin Select (PPS) feature. PPS allows flexible assignment of peripheral signals to GPIO pins, so 2 UART ports, 1 SPI bus, and 1 I2C bus can be active at once on the 44-pin TQFP package. This suits multi-sensor hub designs connecting a barometric sensor over I2C, a display over SPI, and a host PC over UART.
How does the 19-year YTEOL rating of PIC18F47K42-I/PT reduce procurement risk for long-lifecycle industrial products?
The 19-year estimated end-of-life (YTEOL) rating means Microchip plans to manufacture PIC18F47K42-I/PT at least through the mid-2040s, providing designers of industrial instruments, medical devices, and utility meters with decades of assured supply. This eliminates costly redesign cycles triggered by component obsolescence and supports regulatory compliance for products requiring 10 to 15 year post-market spare parts availability. The 6-week standard factory lead time further supports just-in-time procurement strategies for low-to-medium volume production runs.
