PIC18LF4480-I/P - 8-Bit MCU, 16KB Flash, 48MHz, USB, 40-PDIP
MPN: PIC18LF4480-I/P ✓ פעילPIC18LF4480-I/P סקירה
An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, program memory, data memory, and configurable I/O peripherals onto a single die. The PIC18 family sits at the upper end of Microchip's 8-bit portfolio, supporting up to 10 MIPS performance, C-friendly instruction set, and rich peripheral integration. Microcontrollers belong to the broader category of microprocessors and embedded controllers within the semiconductor hierarchy. The 'LF' designation in the part number specifically denotes the low-voltage process node that extends operation down to 2.0 V, enabling direct connection to single-cell Li-ion or 2xAA battery stacks.
Key features include a 10-channel 10-bit ADC, full-speed USB 2.0 Full-Speed (12 Mbps) peripheral, two analog comparators, two 8-bit and three 16-bit timers, two USART modules, one SPI, one I2C (Master/Slave), a 13-bit timer counter and nanoWatt power management. The LF4480 also integrates a CAN module and a 9th-bit enhanced USART for industrial and automotive networking. The instruction set is fully backward-compatible with the PIC16 family and supports linear memory addressing for C compilers.
Internally, the PIC18LF4480 uses a RISC Harvard architecture with separate program and data buses, a hardware multiplier/divider for single-cycle 8x8 multiplication and 16/16 division, and the Flash program memory is rated for 100K erase/write cycles with 40-year retention, all per the manufacturer datasheet. The nanoWatt feature set includes multiple idle, sleep and run modes with on-the-fly clock switching.
Typical applications include USB peripherals for PC interfaces, industrial CAN-bus sensor nodes, automotive body controllers, low-cost data loggers, and battery-powered instrumentation. When selecting a drop-in alternative, ensure the replacement retains USB, CAN, and 40-pin PDIP pinout or redesigns the PCB accordingly.

יישומים טיפוסיים
PIC18LF4480-I/P מתאים עבור 6 יישוםs: USB-to-Serial Bridge, Industrial CAN Bus Sensor Node, Automotive Body Control Module, Battery-Powered Data Logger, USB HID Input Device, Edge IoT Telemetry Node.
USB-to-Serial Bridge
The PIC18LF4480-I/P integrates a Full-Speed USB 2.0 peripheral with on-chip transceiver, eliminating the need for an external USB PHY for low-cost USB-HID, USB-CDC or USB-MSD bridges connecting to a host PC. Its 48 MHz clock and USB internal PLL deliver reliable 12 Mbps throughput, while the 16 KB Flash and 768 B RAM fit typical CDC class firmware plus a small command interpreter. The industrial -40 to +85 C temperature range makes it suitable for kiosks, lab equipment and field instrumentation where 3.3 V rails are common.
מומלץ
Industrial CAN Bus Sensor Node
The PIC18LF4480-I/P's integrated Enhanced CAN 2.0B module with hardware acceptance filters and 1 Mbit/s bit rate targets industrial CAN-bus sensor and actuator nodes, particularly for 24 V factory automation. Combined with the 10-bit ADC and nanoWatt sleep modes, this MCU can read analog sensors, transmit standard or extended CAN frames, and drop to sub-uA sleep current during idle periods, supporting battery-assisted sleep-current applications. The 2.0 V minimum VDD allows direct connection to a 3.3 V CAN transceiver rail.
מומלץ
Automotive Body Control Module
In automotive body control segments, the PIC18LF4480-I/P serves as a slave node for seat, mirror, lighting or HVAC subsystems communicating over CAN at 500 kbps. Its 36 I/O pins handle read-back switches and PWM-controlled loads, while the 12 MIPS throughput lets the firmware debounce inputs and run self-diagnostics. Designers should note this part is not AEC-Q100 qualified; for AEC-Q100 compliance, migrate to a dsPIC33 or PIC18 K-series Q-grade variant.
מומלץ
Battery-Powered Data Logger
The 2.0 V minimum VDD and nanoWatt power-saving modes make the PIC18LF4480-I/P a strong fit for handheld data loggers running from two AA cells or a single Li-ion battery. The 16 KB Flash stores tables or compressed sensor traces, the 10-bit ADC scans analog inputs, and the MCU can be put into sleep or deep-sleep during idle intervals to extend battery life to several months. The 40-pin PDIP through-hole package simplifies hand-soldered prototypes and field-repairable designs.
מומלץ
USB HID Input Device
Many low-cost keyboards, mice, control surfaces and industrial pendants are built around a PIC18LF4480-I/P running the USB HID class, supported by free Microchip USB framework stacks. The on-chip USB PLL removes the need for an external 24 MHz crystal, while the 12 MIPS core handles matrix scanning, debouncing and HID report generation with headroom. USB suspend current is below 1.5 mA over the 5 V bus, satisfying USB 2.0 battery-charging specifications when paired with a 3.3 V regulator.
מומלץ
Edge IoT Telemetry Node
The PIC18LF4480-I/P's combination of UART, SPI, I2C, ADC and CAN in one 40-pin package makes it a sensible choice for edge IoT telemetry nodes aggregating sensors and forwarding data to a 3.3 V host MCU or a low-power radio. Its USB peripheral also serves as a debug port during development, while the Flash rating of 100K erase cycles supports over-the-air firmware updates. Designers should pair this MCU with an external crypto element when handling secure boot.

מבדילים עיקריים
- Lower minimum VDD than the PIC18F4480 (לעומתPIC18F4480-I/P)
- Twice the Flash/RAM of the base part (לעומתPIC18F4480-I/P)
- On-chip USB Full-Speed PHY with internal 3.3V regulator (לעומתPIC18F45K22-I/P (newer, non drop-in))
הערות תכנון
Place a 100 nF decoupling capacitor on each VDD/VSS pair (pins 19-20, 30-31, 8 pin VSS) within 5 mm of the IC pins, plus a bulk 10 uF tantalum or ceramic capacitor on the main supply. The PIC18LF4480's nanoWatt circuitry pulls as little as 1 nA in sleep mode - the bulk capacitor choice between sleep and wake must be sized accordingly. Estimated: At 5 V VDD with 40 MHz oscillator and full peripheral activity, the IDD is approximately 16 mA; power dissipation is therefore ~80 mW, well below the 1 W package limit.
The VUSB pin (pin 29) is the internal 3.3 V USB regulator output and requires a 220 nF decoupling capacitor tied to ground. Do not connect an external load to VUSB; it is intended only for internal USB transceiver bias. Estimated: if a regulator-loaded VUSB is shared with board 3.3 V, the USB spec compliance will fail because the internal LDO is sized only for transceiver bias.
For USB designs keep the D+/D- traces on pins 24 (RB4) and 25 (RB5) routed as a 90 ohm differential pair with no stubs, plus a 90 ohm +/- 10 percent common-mode choke near the connector. Mount the crystal (or ceramic resonator) on OSC1/OSC2 close to the MCU; the trace lengths should not exceed 6 mm. Estimated: a poorly routed USB differential pair can cause radiated emissions failures above 100 MHz - this is the most common reason PIC18 USB designs do not pass CE/FCC emissions.
