Applications
The PIC18F46J13-I/ML targets USB-enabled embedded systems, human interface devices, and data-logging instruments where an 8-bit processor with 64 KB Flash and a full peripheral set suffices. Its 48 MHz clock with internal PLL supports USB Full-Speed communications at 12 Mbps, making it a compact single-chip solution for USB CDC, HID, and MSD class devices. XLP technology and a 2.15 V minimum supply extend its use to battery-operated sensors, portable meters, and IoT edge nodes requiring long field service life.

Frequently Asked Questions
Does the PIC18F46J13-I/ML support USB connectivity, and at what speed?
Yes, the PIC18F46J13-I/ML includes a USB Full-Speed module operating at 12 Mbps, clocked from the 48 MHz PLL output. This allows the device to implement USB CDC virtual COM port, HID keyboard or mouse, and MSD flash drive device classes without an external USB bridge chip, reducing BOM cost and PCB component count.
What is the minimum supply voltage of the PIC18F46J13-I/ML and at which clock frequency does it run there?
The PIC18F46J13-I/ML operates at a minimum supply voltage of 2.15 V while running at up to 8 MHz. This allows direct operation from two NiMH cells or a partially discharged lithium battery, extending useful battery life in portable data logging and field metering applications well beyond what 3.3 V-only devices can achieve.
How much program memory and RAM does the PIC18F46J13-I/ML provide, and is it sufficient for a USB data logger?
The PIC18F46J13-I/ML offers 64 KB of self-programmable Flash and 4 KB of SRAM. For a USB CDC data logger reading from a 10-bit ADC at 1 kHz and streaming samples over 12 Mbps USB, 4 KB of RAM provides enough buffer depth for burst transfers, while 64 KB of Flash accommodates the application, USB stack, and FAT file system code.
What I/O and communication peripherals are built into the PIC18F46J13-I/ML?
The PIC18F46J13-I/ML includes a 10-bit ADC with multiple channels, two EUSART serial ports, two SPI modules, two I2C modules, multiple CCP/PWM capture-compare-PWM units, and multiple timers. This on-chip peripheral density allows a single 44-pin device to simultaneously manage sensor sampling, motor PWM, serial host communication, and USB connectivity without external glue logic.
For a portable industrial handheld meter, how does the 44-pin QFN package of PIC18F46J13-I/ML compare to a 44-pin TQFP alternative?
The PIC18F46J13-I/ML QFN-44 (8x8 mm) occupies roughly 64 mm2 versus approximately 104 mm2 for a comparable 44-pin TQFP package. The 38% footprint reduction and the absence of gull-wing leads in QFN also lower the profile, easing integration into slim handheld instrument enclosures where PCB height clearance is constrained.
