- 48 MHz maximum clock delivering 12 MIPS ensures responsive real-time control and fast communication protocol handling in an 8-bit PIC18 architecture
- nanoWatt technology with deep sleep modes reduces power consumption to sub-microamp levels, extending battery life in portable and energy-harvesting designs
Applications
The PIC18F46J11-I/ML targets medium-complexity embedded control applications such as industrial automation panels, home appliance controllers, and consumer electronics requiring a balance of memory, speed, and low power. With 44 I/O pins in a compact QFN-44 package, it connects directly to sensors, displays, keypads, and communication modules without I/O expanders. Its nanoWatt sleep modes and 48 MHz operating frequency make it suitable for battery-powered data loggers and remote monitoring units that wake periodically to sample, process, and transmit data.

Frequently Asked Questions
How does PIC18F46J11-I/ML's 64 KB Flash compare to smaller PIC18 variants for firmware storage needs?
PIC18F46J11-I/ML offers 64 KB of Flash, which is 4× the capacity of entry-level 16 KB PIC18 devices. This allows firmware to include a USB stack, RTOS, communication drivers, and application code simultaneously without memory constraints, making it practical for more capable embedded applications while staying within the cost-effective 8-bit PIC18 ecosystem.
At 48 MHz, what real-world processing throughput does PIC18F46J11-I/ML deliver for control algorithms?
Running at 48 MHz, the PIC18F46J11-I/ML executes up to 12 MIPS (million instructions per second), since the PIC18 core executes most instructions in 4 clock cycles. This throughput supports running PID control loops at update rates up to 50 kHz or higher, handling SPI/I2C/UART communications, and managing interrupt-driven sensor sampling within the same real-time firmware task.
How many I/O pins does PIC18F46J11-I/ML expose and what does that enable in a sensor hub design?
PIC18F46J11-I/ML provides 44 pins in QFN-44, of which up to 36 are configurable as GPIO. A sensor hub design can allocate 12 ADC inputs for analog sensors, 2 UART ports for RS-232/RS-485 communication, 2 SPI buses for fast sensor interfaces, and 1 I2C bus for configuration EEPROMs—all within a single 7 mm × 7 mm QFN package without requiring external I/O expanders.
Which low-power mode does PIC18F46J11-I/ML offer for extending battery life in a remote sensor node?
PIC18F46J11-I/ML features nanoWatt technology that includes a deep sleep mode drawing less than 100 nA. Pairing this with a watchdog timer wakeup every 8 seconds, the device can run on a pair of AA alkaline cells (approximately 2500 mAh combined) for several years in a duty-cycled remote temperature or humidity logger application, with brief 48 MHz active bursts for measurement and transmission.
