Frequently Asked Questions
What USB speed and voltage range does the PIC18LF25J50-I/SS support for battery-powered accessories?
The PIC18LF25J50-I/SS supports full-speed USB 2.0 at 12 Mbps and operates from a supply voltage of 2.0 V to 3.6 V. This low-voltage range makes it directly compatible with single-cell LiPo batteries at 3.0 V–3.6 V without a step-up regulator, allowing compact USB-connected battery devices with minimal power-conversion overhead.
How much flash and RAM does the PIC18LF25J50-I/SS provide, and what clock speed does it run at?
The PIC18LF25J50-I/SS includes 32 KB of self-programmable flash program memory and 4 KB of SRAM data memory. It runs at a maximum clock frequency of 48 MHz when operating from USB-derived clock sources, or at 8 MHz when the supply is as low as 2 V, giving designers flexibility between performance and power consumption.
When is PIC18LF25J50-I/SS a lower-power alternative to PIC18F25J50 for portable USB designs?
The PIC18LF25J50-I/SS is the low-voltage variant of the PIC18F25J50 family, operating from 2.0 V to 3.6 V versus the standard 2.0 V to 5.5 V range. Its nanoWatt XLP deep-sleep current drops to below 100 nA in sleep mode, making it preferable when the device spends most of its time in sleep and wakes periodically to transmit USB data packets, extending battery life significantly over the standard variant.
What peripherals does the PIC18LF25J50-I/SS integrate alongside USB for sensor interfacing?
Beyond the USB engine, the PIC18LF25J50-I/SS integrates a 10-bit ADC with multiple input channels, DMA channels for autonomous data transfers, SPI and I2C interfaces, and multiple UART modules. These peripherals allow the MCU to simultaneously collect analog sensor data via the 10-bit ADC, buffer it using DMA, and transmit it over USB at 12 Mbps without burdening the CPU core.
