PIC18F4515-E/PT 概要
A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture, RISC-based single-chip computer that integrates CPU, Flash program memory, RAM, EEPROM, timers, communication peripherals, and I/O on one die. Within the broader semiconductor taxonomy, PIC MCUs belong to Microcontrollers > 8-bit MCUs > Flash MCUs > Embedded Controllers, and they are designed for deterministic real-time control with low power consumption. The PIC18 family is the upper end of Microchip's 8-bit line, adding 16-bit-wide instructions, hardware multiply, and linear program memory up to 2 MB.
Key features of the PIC18F4515 include 48 KB Flash (24K x 16), 3.8 KB RAM, 256 B EEPROM, a 10-bit A/D converter with 13 input channels (shared with analog-capable I/O), a CAN 2.0B controller with DMA-style message buffering, an Enhanced USART, MSSP (SPI/I2C), two CCP and one ECCP module, two 8-bit and three 16-bit timers, a 16-bit timer with Gate Control for motor control, and the nanoWatt power-managed run/IDLE/sleep modes. The 44-TQFP package gives a compact 10x10 mm footprint with 0.80 mm pitch and supports standard SMT assembly.
Typical applications for the PIC18F4515 include CAN node endpoints in automotive body and chassis ECUs, industrial sensor hubs, motor control boards, building automation nodes, and any embedded system that needs CAN bus connectivity plus moderate Flash. The 10-bit ADC and 13 analog inputs suit it well for multi-signal acquisition. The device supports In-Circuit Serial Programming (ICSP) via MPLAB X IDE, MPLAB XC8 C compiler, and PICkit 5 debug probe.
When designing with the PIC18F4515, reserve 5V supply margin and follow Microchip's recommended decoupling (0.1 uF + bulk) on VDD/VSS pairs, plus a 10 uF bulk on AVDD/AVSS for ADC accuracy. For CAN, terminate the bus with 120 ohm at each end and respect the bus-length vs baud-rate tradeoff. Migration paths include the PIC18F45K22 (more RAM, nanoWatt XLP) and the PIC18F46K22, both in pin-compatible TQFP-44.

主な用途
PIC18F4515-E/PT の用途: 6 件s: Automotive CAN Node, Industrial Sensor Hub, BLDC Motor Controller, Building Automation Node, User Interface Controller, Battery Charger / Power Supply Controller.
Automotive CAN Node
The PIC18F4515-E/PT is well-suited to automotive CAN bus nodes because of its integrated Enhanced CAN 2.0B controller, 36 I/O pins for sensor and actuator interfaces, and Extended -40C to +125C operating range. In a typical body or chassis ECU, the MCU handles CAN message transmission, processes switch and analog inputs from seats/doors/lights, and drives relays and LEDs via PWM. The 10-bit ADC with 13 channels handles multiple sensor readings (temperature, position, current) per scan loop, while the ECCP module generates PWM for motor or lighting control. Use the PIC18F4515's ECAN bus-off recovery and 32-message buffer to keep communication latency under 1 ms in a 250 kbps CAN network. Note: AEC-Q100 qualification is not formally listed for PIC18F4515; for AEC-Q100 programs Microchip recommends the K-series PIC18FxxK22.
おすすめ
Industrial Sensor Hub
Use the PIC18F4515-E/PT as a multi-signal sensor hub in industrial automation. The 13-channel 10-bit ADC digitizes analog inputs from thermocouples, pressure transducers, 4-20 mA loops, and potentiometers. The MSSP and EUSART peripherals connect to SPI/I2C sensor chains (e.g., accelerometers, EEPROMs) and to a host PLC over RS-485 with a transceiver like the MAX485. The 48 KB Flash fits substantial Modbus or CANopen protocol stacks, while 3968 bytes of RAM hold calibration tables and circular buffers. The 'E' temperature grade (-40C to +125C) tolerates the warm interior of a control cabinet. Use the nanoWatt sleep modes between scans to cut average current below 1 mA in battery-backed remote sensors.
おすすめ
BLDC Motor Controller
The PIC18F4515-E/PT drives a small three-phase BLDC or PMSM motor using its ECCP (Enhanced Capture/Compare/PWM) module plus the 16-bit timer with Gate Control. In a 6-step trapezoidal or simple sinusoidal FOC algorithm, the ECCP generates complementary PWMs with dead-band insertion to switch the gate drivers (e.g., IR2104, FAN7888). Hall sensors or back-EMF feedback connect to the CCP and ADC channels; current sensing uses the 10-bit ADC on a low-side shunt. 48 KB Flash fits the state machine and small look-up tables, and the 'E' temperature grade handles the motor compartment. For higher-performance sinusoidal FOC, consider migrating to dsPIC33F family (e.g., DSPIC33FJ64MC802).
おすすめ
Building Automation Node
Deploy the PIC18F4515-E/PT in HVAC or building-automation nodes that need both CAN (for sub-bus communication with sensor/actuator modules) and RS-485 (for the backbone Modbus RTU link). Its 36 I/O pins handle digital inputs (door switches, occupancy sensors), relay outputs (lights, fans), analog inputs (CO2, temperature), and a keypad/LCD. The 48 KB Flash holds BACnet or KNX-style protocol stacks plus a small RTOS or cooperative scheduler. The nanoWatt power-managed modes allow the node to drop to under 10 uA during unoccupied periods. Use the internal RC oscillator with PLL for low-jitter timing and an external 32.768 kHz crystal for RTC accuracy when needed.
おすすめ
User Interface Controller
The PIC18F4515-E/PT handles keypad scanning, LCD or TFT display driving, and LED matrix control in human-machine interface (HMI) panels. Its 36 I/O and EUSART enable a simple command set to a host processor or to a remote display. The MSSP port drives an SPI TFT or OLED display controller (e.g., SSD1351, ILI9341) at up to 10 MHz, refreshing small UIs comfortably. PWM channels via CCP modules dim LEDs or control backlight brightness through the ECCP. The 48 KB Flash holds framebuffer and small fonts in lookup tables, while the 'E' temperature grade allows operation near displays that warm up. Combine with an external EEPROM (24LC256) for parameter storage.
おすすめ
Battery Charger / Power Supply Controller
Use the PIC18F4515-E/PT as the digital control brain for a smart sealed lead-acid (SLA) or Li-ion charger. The 10-bit ADC senses charge current (via shunt), battery voltage, and temperature; the ECCP module produces the PWM that drives the converter through a gate driver. The MSSP port talks to an I2C gas gauge or EEPROM for logging. Firmware implements CC/CV charge profiles, temperature-foldback, and timer-based termination. The 'E' temperature grade tolerates enclosure heating. The nanoWatt sleep modes drop the controller to a few microamps between charge cycles. For higher switching frequencies (>100 kHz) and synchronous rectification, consider the dsPIC33F for its DSP-friendly instruction set.

設計ノート
Decouple every VDD/VSS pair with a 0.1 uF X7R ceramic placed within 5 mm of the pin, plus a single 10 uF bulk on the VDD rail near the MCU. For ADC accuracy, decouple AVDD/AVSS with a 0.1 uF + 10 uF combination per Microchip AN588. The PIC18F4515-E/PT operates from 4.2V to 5.5V only; do not attempt 3.3V operation. Add a ferrite bead or small inductor on VDD if the supply is shared with switching regulators, and place a TVS diode on the external supply for automotive transients.
Route the 40 MHz oscillator traces as short and symmetric as possible; keep them over a continuous ground plane and away from switching nodes. Place the load capacitors for the crystal within 3 mm of the OSC1/OSC2 pins. The TQFP-44 has an exposed thermal pad (die attach paddle) under the package - tie it to ground through multiple vias for thermal relief and EMC performance. The TQFP-44 footprint is 10x10 mm with 0.80 mm pitch - allow 0.40 mm clearance between pads for stencil aperture.
Do not assume PIC18F452 firmware runs unchanged on PIC18F4515 - the memory map, ADC channel count, and ECAN register block differ. When migrating firmware between PIC18F45xx variants, always re-set the CONFIG1H through CONFIG2H words for the new part number and re-validate the clock and watchdog settings. Configure unused I/O pins as outputs and tied low; configure unused interrupts as off and their flags cleared to avoid spurious wakeups from the nanoWatt sleep mode.
CAN bus signals require 120 ohm termination at each end of the bus, and the CANH/CANL traces should be routed as a differential pair with characteristic impedance near 120 ohms. Keep stub lengths to the transceiver under 1/10 of the bit time. For ECAN at 1 Mbps, total bus length should not exceed 25-30 meters. Use an external CAN transceiver like the MCP2551 or TJA1050; the MCU's ECAN peripheral is a digital controller only and cannot drive the bus directly.
Estimated: The PIC18F4515-E/PT in the TQFP-44 package has a typical theta_JA of approximately 50 C/W on a 4-layer JEDEC test board. At 40 MHz, core current is ~16 mA at 5V (~80 mW). Even with all I/O loaded at 25 mA total, total dissipation stays well under 200 mW, so junction temperature rise is ~10 C above ambient. The 'E' rated -40C to +125C operating range covers virtually all embedded enclosure environments without additional heatsinking.
