Frequently Asked Questions
What flash memory and RAM capacity does PIC18F4550-I/P provide?
PIC18F4550-I/P includes 32 KB of self-programming flash memory and 2 KB of SRAM, plus 256 bytes of EEPROM. This capacity supports mid-complexity firmware including USB class drivers and real-time control loops running at up to 48 MHz.
Which USB speed does PIC18F4550-I/P support and what does that mean for data transfers?
It supports full-speed USB 2.0 at 12 Mbps, sufficient for HID, CDC, and mass-storage device classes. The on-chip USB transceiver operates from a 3.3 V regulated rail, removing the need for an external UTMI PHY in designs with tight BOM budgets.
How many ADC channels are available on PIC18F4550-I/P and what is their resolution?
The device provides 13 analog input channels connected to a 10-bit successive-approximation ADC, delivering a resolution of approximately 4.88 mV per LSB at a 5 V reference. This makes it suitable for multi-sensor data acquisition in industrial and consumer applications.
