Key Features
- Integrated full-speed USB 2.0 module eliminates external USB controllers, reducing BOM cost and PCB area in HID and CDC device designs
- Operates at 48 MHz on 5 V or as low as 8 MHz at 2.15 V, allowing flexible power-performance trade-offs in battery-constrained applications
- 16 KB self-programmable Flash and 3.8 KB RAM in a narrow SOIC-28 package enable feature-rich firmware with in-field update capability
Applications
The PIC18F24J50-I/SO targets USB-connected embedded applications such as HID keyboards, mice, game controllers, and CDC virtual-COM-port bridges where a self-contained 8-bit MCU with on-chip USB simplifies board design. Its combination of 16 KB Flash and 3.8 KB RAM supports moderately complex firmware including USB descriptor management, interrupt-driven ADC sampling, and UART forwarding. The compact SOIC-28 footprint suits space-sensitive designs in consumer electronics, industrial handheld devices, and laboratory instruments.

Frequently Asked Questions
At what voltage can the PIC18F24J50-I/SO operate at reduced clock speed, and why does this matter for battery-powered designs?
The PIC18F24J50-I/SO can operate at 2.15 V running at 8 MHz, significantly reducing active current consumption compared to full 48 MHz at 5 V operation. This allows designers to use two AA cells or a single-cell LiPo in products such as wireless USB dongles or portable data loggers without a regulated 5 V rail.
How much on-chip Flash and RAM does the PIC18F24J50-I/SO provide, and what type of USB does it support?
The device provides 16 KB of self-programmable Flash program memory and 3.8 KB of RAM data memory. It integrates a full-speed USB 2.0 module supporting 12 Mbit/s transfers, enabling HID, CDC, or custom USB device classes without any external USB bridge chip.
Which SOIC-28 package dimensions and pin pitch should PCB designers use for the PIC18F24J50-I/SO layout?
The SOIC-28 package uses a 1.27 mm pin pitch with a body width of 7.5 mm and a total footprint length of approximately 18.1 mm. Designers should route a 100 nF bypass capacitor within 2 mm of each VDD pin and keep the USB D+ and D- traces under 50 mm with matched lengths to maintain USB signal integrity.
When would a designer choose PIC18F24J50-I/SO over a PIC18F2550 for a new USB HID design?
The PIC18F24J50-I/SO runs at up to 48 MHz versus 40 MHz for PIC18F2550 and provides 3.8 KB RAM compared to 2 KB, offering more headroom for USB descriptor buffers and application data. Its SOIC-28 format is identical, so migration requires only a firmware recompile and minor linker script changes to address the larger memory map.
