Key Features
- 8-bit PIC18 core at up to 48 MHz with full-speed USB 2.0 device interface for HID, CDC, and custom class applications
- 64 KB self-programmable Flash and 3800 B RAM with DMA for efficient USB data buffering without CPU overhead
- Low-voltage operation from 2 V at 8 MHz, ideal for USB-powered portable instruments and battery-backed data loggers
Applications
PIC18LF26J50-I/SO is suited for USB-connected HID peripherals, CDC virtual COM port bridges, and small USB data acquisition devices. Its 64 KB Flash and 3800 B RAM provide enough program and buffer space for MSD bootloaders and custom USB protocols at 48 MHz. The 2 V minimum operation at 8 MHz extends to sleep-wake USB wake-up designs in portable medical and industrial instrumentation.

Frequently Asked Questions
How does the PIC18LF26J50-I/SO support full-speed USB 2.0 while maintaining low power at 2 V?
The PIC18LF26J50-I/SO integrates a full-speed USB 2.0 device engine running at 48 MHz for USB transactions and scales down to 8 MHz at 2 V for low-power sleep states. This combination allows USB-enumerated HID or CDC devices to achieve under 1 mA standby current while maintaining full 12 Mbps USB throughput when active.
For a USB CDC virtual COM port design, how does the 3800 B RAM and DMA of the PIC18LF26J50-I/SO help?
The PIC18LF26J50-I/SO provides 3800 bytes of RAM with DMA channels that allow USB endpoint buffers to be filled and drained without CPU intervention. This reduces ISR overhead by up to 40%, enabling the 48 MHz core to simultaneously handle UART bridging at 115200 baud while maintaining 12 Mbps USB data rate with fewer dropped bytes.
When is the PIC18LF26J50-I/SO preferred over the PIC18F2550 for a new USB peripheral design?
Choose the PIC18LF26J50-I/SO over the PIC18F2550 when your design needs larger 64 KB Flash versus 32 KB, more RAM (3800 B vs 2 KB), and lower voltage operation down to 2 V. The LF suffix low-voltage variant also reduces active current by roughly 20% at 3.3 V operation, which matters in bus-powered USB accessories limited to 100 mA from the host.
