Key Features
- Full-speed USB 2.0 device interface at 12 Mbps with on-chip USB transceiver eliminates external USB bridge chips in PIC18-based designs
- 8-bit PIC18 core running at 48 MHz provides 12 MIPS throughput for USB interrupt servicing alongside application tasks
- 16KB Flash program memory and 768 bytes on-chip RAM support moderate-complexity USB firmware stacks and HID/CDC class drivers
Applications
The PIC18F2450-I/SO is purpose-built for USB peripheral designs such as HID keyboards, virtual COM port adapters, custom USB data acquisition dongles, and embedded USB bootloaders where the MCU must act as a USB 2.0 Full Speed device at 12 Mbps. Its 48 MHz operating frequency provides adequate processing headroom for USB interrupt handling plus concurrent UART or SPI sensor communication in handheld instruments and USB test equipment. The standard 28-pin SOIC package simplifies layout and supports automated assembly in moderate-volume USB accessory and laboratory instrument production.

Frequently Asked Questions
What USB speed class does the PIC18F2450-I/SO support and how does this affect data transfer rates in a CDC virtual COM port design?
The PIC18F2450-I/SO supports USB Full Speed at 12 Mbps, delivering a practical CDC virtual COM port throughput of approximately 1 Mbps after USB protocol overhead. This is 10 times faster than a Low Speed (1.5 Mbps) USB device and sufficient for streaming ADC data, firmware updates, or UART bridging up to 921600 baud without a separate USB-UART bridge IC, reducing BOM cost by one component.
How much Flash and RAM does the PIC18F2450-I/SO provide and is it sufficient to run both a USB stack and application logic?
The PIC18F2450-I/SO provides 16KB of Flash program memory and 768 bytes of on-chip SRAM. A typical USB HID or CDC class firmware stack for PIC18 (such as Microchip's USB Device Library) occupies approximately 6-8KB of Flash and 200-300 bytes of RAM, leaving 8KB of Flash and 500 bytes of RAM for application code. This is adequate for simple sensor reading, LED control, or button input firmware but leaves limited headroom for complex protocol stacks.
How does the PIC18F2450-I/SO compare to the PIC18F2550 when selecting a USB-capable MCU for a cost-sensitive design?
The PIC18F2450-I/SO has 16KB Flash versus the PIC18F2550's 32KB Flash, and 768 bytes RAM versus 2KB, making the 2450 the better choice for simple HID or CDC applications where code size fits within 16KB and flash cost must be minimized. The PIC18F2550 is preferred when the firmware requires both USB and extended peripheral drivers exceeding 16KB, or when RAM-intensive USB bulk transfer buffers larger than 512 bytes are needed. Both run at 48 MHz in the same 28-pin SOIC-28 footprint.
