PIC18F4515-E/PT 개요

The Microchip Technology PIC18F4515-E/PT is an 8-bit RISC Flash microcontroller from the PIC18F family, featuring 48 KB of program Flash, 3968 bytes of RAM, 256 bytes of EEPROM, and 36 I/O pins in a 44-pin TQFP surface-mount package. It executes instructions at up to 10 MIPS from a 40 MHz internal clock (10 MHz input oscillator, 4x PLL option to 40 MHz) and integrates a 10-bit ADC with up to 13 channels, multiple Enhanced USART/CCP/ECCP peripherals, an Enhanced CAN 2.0B module, and the nanoWatt power-managed sleep modes that made the PIC18F45xx series a workhorse for industrial and automotive embedded designs. The 'E' suffix designates the Extended (-40C to +125C) operating temperature range, while the '/PT' suffix specifies the 44-pin TQFP (Thin Quad Flat Pack) package supplied in Tray.

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.

일반적인 애플리케이션

PIC18F4515-E/PT 적합 용도: 6 애플리케이션s: 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.

🏭

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.

⚡

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).

🧩

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.

📺

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.

🔋

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.

What is the program memory size of PIC18F4515-E/PT?
The PIC18F4515-E/PT contains 48 KB of Flash program memory (organized as 24K x 16 instruction words), plus 3968 bytes of RAM and 256 bytes of data EEPROM. This memory split is part of the PIC18F45xx family and supports in-circuit self-programming via ICSP. According to Microchip documentation, the Flash supports 10K erase/write cycles typical and 100K read cycles, making it suitable for field-upgradable industrial firmware.
What is the operating voltage range of PIC18F4515-E/PT?
The PIC18F4515-E/PT operates from 4.2 V to 5.5 V on VDD. It is the classic 5V PIC18 part, not a wide-range 1.8V-5.5V variant. For lower-voltage operation in battery or USB-powered designs, consider the 'LF' (low-voltage) PIC18LF45xx parts. Decouple each VDD/VSS pair with 0.1 uF ceramic plus a 10 uF bulk near the MCU per Microchip AN588.
Does PIC18F4515-E/PT have CAN bus support?
Yes, the PIC18F4515-E/PT integrates an Enhanced CAN 2.0B controller supporting CAN 2.0A and 2.0B frames, with hardware acceptance filters, masks, and message buffers for bus-off recovery. It is one of the distinguishing features of the PIC18F45xx family versus the PIC18F452, which lacks ECAN. For full CAN physical-layer compliance you still need an external CAN transceiver such as the MCP2551 or TJA1050 between the MCU and the bus.
What is the difference between PIC18F4515 and PIC18F452?
The PIC18F4515 is the higher-memory and higher-feature successor to the PIC18F452. It retains the same PIC18 instruction set and 44-pin TQFP/PLCC pinout but adds 48 KB Flash (vs 32 KB), more RAM, 256 B EEPROM, and a 10-bit ADC versus the PIC18F452's 5-channel ADC variant in some packages. Code compiled for PIC18F452 will generally run on PIC18F4515 after adjusting memory map; the reverse is not true without firmware reduction.
Where can I download the PIC18F4515-E/PT datasheet PDF?
The PIC18F4515-E/PT datasheet (document 39609E, "28/40/44-Pin High-Performance, Enhanced Flash Microcontrollers with 10-bit A/D and nanoWatt Technology") is available from Microchip's website at the product page for PIC18F4515. Third-party mirrors may host an identical PDF; we recommend Microchip's official link for the latest revision. The document covers electrical characteristics, pinouts, memory maps, and the instruction set reference.
What is the maximum clock frequency of PIC18F4515-E/PT?
The PIC18F4515-E/PT supports up to 40 MHz system clock, corresponding to a 10 MHz crystal or oscillator multiplied 4x by the internal PLL, yielding 10 MIPS instruction throughput. In the F-extended (F) variants, the maximum FOSC is 40 MHz at 4.2-5.5V. In low-voltage variants (LF) the same 40 MHz is supported down to 2.0V. Always configure CONFIG1H for HS or HS+PLL when using an external 10 MHz source.
How many ADC channels does PIC18F4515-E/PT have?
The PIC18F4515-E/PT has up to 13 analog input channels multiplexed into a single 10-bit successive-approximation ADC. Channel count is package-dependent; on the 44-pin TQFP, 13 channels are available because of the maximum analog-capable I/O. Acquisition time is programmable via the ADCON2 register (ACQT bits), and conversion takes 11 TAD. For best accuracy at low VDD variance, keep AD clock below 1 MHz and use AVDD/AVSS decoupling per the datasheet.
What package is the PIC18F4515-E/PT in?
The PIC18F4515-E/PT uses the 44-pin TQFP (Thin Quad Flat Pack) package, designated by the /PT suffix. The package is 10 mm x 10 mm with 0.80 mm lead pitch and 1.0 mm body thickness, supplied in Tray for production. The same silicon is available in /P (40-pin PDIP), /SP (28-pin SPDIP), and /ML (44-pin QFN) options, all from the PIC18F45xx family.
What is a drop-in replacement for PIC18F4515-E/PT?
Drop-in TQFP-44 alternatives within the Microchip portfolio include PIC18F4525-I/PT (48 KB, no ECAN), PIC18F4620-I/PT (64 KB Flash, ECAN), and PIC18F46K22-I/PT (K-series 64 KB, nanoWatt XLP, more peripherals). These parts share the 44-pin TQFP footprint with PIC18F4515-E/PT, but firmware must be re-compiled for the new part's CONFIG bits, peripheral register map, and memory layout. Outside Microchip, no cross-vendor drop-in 44-pin TQFP PIC-equivalent exists.
What is the price of PIC18F4515-E/PT in 2026?
As of 2026-09-27, the PIC18F4515-E/PT unit price is approximately 8.62 USD at qty 1, with volume breaks down to around 5.21 USD at qty 1000 on the open distributor market. Stock is generally available at DigiKey, Mouser, and Microchip Direct; lead time for non-stock volumes is typically 6-10 weeks from the factory. We recommend checking live distributor stock pages before quoting customer-facing BOMs because distributor inventory moves quickly.
Where to buy PIC18F4515-E/PT online?
PIC18F4515-E/PT is in stock at major authorized distributors including DigiKey (part number PIC18F4515-E-PT-ND), Mouser, Arrow, and Microchip Direct (factory-direct). We recommend DigiKey or Microchip Direct for first-article prototypes and Microchip Direct or Arrow for production volumes. Always confirm authorized-distributor status to avoid counterfeit units; PIC18F4515-E/PT is widely cloned, especially in older -E temperature grades.
Is PIC18F4515-E/PT RoHS compliant?
Yes, the PIC18F4515-E/PT is RoHS compliant per Microchip's material declaration and the Pb-free finish on the TQFP leads. It also meets REACH SVHC requirements as of the current date. The part is rated for industrial and automotive-grade operating temperatures from -40C to +125C. AEC-Q100 automotive qualification is not formally listed for the PIC18F4515 family; for AEC-Q100, Microchip recommends the PIC18FxxK22 family.
What is the difference between PIC18F4515-I/PT and PIC18F4515-E/PT?
The 'I' suffix in PIC18F4515-I/PT denotes the Industrial temperature grade (-40C to +85C), while the 'E' suffix in PIC18F4515-E/PT denotes the Extended temperature grade (-40C to +125C). Both share identical silicon, pinout, and electrical characteristics. For under-hood automotive or industrial control panels exposed to heat, choose 'E'; for indoor consumer/office equipment, 'I' is sufficient and cheaper. The TQFP-44 package and Flash size are the same.
Can PIC18F46K22-I/PT replace PIC18F4515-E/PT?
Yes, the PIC18F46K22-I/PT is the recommended drop-in upgrade for PIC18F4515-E/PT in the same 44-pin TQFP package. It offers 64 KB Flash (vs 48 KB), 3.9 KB RAM, more peripherals including 2x ECAN, and the nanoWatt XLP low-power modes. The K22 family is current-generation with active longevity support. Pin-compatibility is preserved for the 44-pin TQFP, but verify your firmware against the new CONFIG bits and peripheral library before committing to production.
What compiler should I use for PIC18F4515-E/PT?
Use Microchip's MPLAB XC8 C compiler (current version supports all PIC18F devices, free Standard edition with optimization options disabled) or the MPLAB XC8 PRO edition for full optimization. For assembly development, MPASM is bundled with MPLAB X IDE. Firmware debugging requires a PICkit 5, ICD 4, MPLAB Snap, or compatible in-circuit debugger. The free MPLAB Xpress cloud IDE also targets PIC18F4515-E/PT for quick prototyping.

설계 노트

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.
