PIC18F45Q10-E/P 개요

The Microchip Technology PIC18F45Q10-E/P is an 8-bit PIC microcontroller in the PIC18F2x/4x/5xQ10 family, integrating 32KB of FLASH program memory, 64MHz maximum CPU clock, and 5V operation in a 40-pin PDIP through-hole package. The Q10 family targets robust, real-time control and sensor-node applications, providing 5V-tolerant I/O for higher noise immunity compared to typical 3.3V MCUs.

Background: A microcontroller (MCU) is an integrated circuit that combines a CPU core, non-volatile program memory (FLASH/ROM), volatile data memory (RAM), and a rich set of peripheral blocks (timers, ADC, communication interfaces) on a single silicon die. Within the MCU taxonomy, the PIC18F45Q10 belongs to the 8-bit family (PIC18 core) > enhanced mid-range with nanoWatt XLP power management > PIC18-Q10 sub-family > 40-pin variants. The Functional Safety (FuSa) family designation signals that the device includes diagnostics and documentation suitable for IEC 60730 class B safety functions in household appliances.

Key features of the PIC18F45Q10 include a 10-bit ADC with Computation (ADC2) supporting averaging, filtering, and Capacitive Voltage Divider (CVD) for touch sensing, Configurable Logic Cells (CLCs) for hardware-level glue logic, Complementary Waveform Generator (CWG) with auto-shutdown, and multiple Core-Independent Peripherals (CIPs) such as EUSART, MSSP (I2C/SPI), and 16-bit PWM with multiple capture/compare channels. The device operates from 1.8V to 5.5V (F-version, extended) and is offered in the -40C to +125C extended industrial temperature range, denoted by the -E suffix.

The PIC18F45Q10 uses an enhanced Harvard architecture with a 16-bit instruction word and an 8-bit data path, executing most instructions in one instruction cycle (4 clock periods). Internal oscillator flexibility (32kHz-64MHz HFINTOSC), programmable PLL, and nanoWatt XLP sleep modes (< 100 nA typical) make the part attractive for battery- or energy-harvesting sensor nodes where quiescent draw dominates the energy budget.

Typical applications include industrial control sensor nodes, consumer appliances requiring IEC 60730 class B functional safety (white goods, washing machines, dishwashers), touch-sensing human-machine interfaces using the CVD peripheral, low-power IoT end-nodes with sleep duty cycling, and small motor-driver companions with the CWG and PWM peripherals. The 5V I/O is also valued for retrofitting legacy 5V systems.

When designing with this device, allocate decoupling capacitors (100 nF per VDD pin, plus a bulk 10 uF) close to the IC, route MCLR with proper pull-up, and reserve an ICSP header on the PCB for in-circuit programming and debugging. The Q10 family's CIPs can offload tasks traditionally handled in firmware, reducing CPU wake-up frequency.

This page synthesizes distributor pricing, drop-in alternatives, design notes, and AEO-optimized FAQ not found in the manufacturer datasheet alone, providing engineers and procurement teams a single reference for part selection.

일반적인 애플리케이션

PIC18F45Q10-E/P 적합 용도: 6 애플리케이션s: Functional Safety Appliance Controller, Capacitive Touch Sensing HMI, Industrial Sensor Node, Small Motor / Fan Driver Companion, Low-Power IoT End Node, Consumer White Goods Control Board.

💡

Functional Safety Appliance Controller

The PIC18F45Q10-E/P integrates the Functional Safety (FuSa) documentation library and on-die diagnostics (BOR, windowed watchdog, RAM/FLASH BIST) required for IEC 60730 class B compliance, making it well suited to household appliances such as washing machines, dishwashers, and refrigerators. Its 32KB FLASH accommodates class B self-test routines alongside the application firmware, while 5V-tolerant I/O interfaces directly with line-voltage optocouplers and triac drivers used in motor and heater control. Compared with a generic 8-bit MCU, the Q10 reduces external safety components and shortens class B certification effort.

🧩

Capacitive Touch Sensing HMI

The PIC18F45Q10-E/P's ADC2 with Capacitive Voltage Divider (CVD) hardware offloads the charge-balancing timing required for robust capacitive touch buttons and sliders, reducing CPU wake events and enabling touch wake-up from nanoWatt XLP sleep. Microchip's mTouch CVD library supports up to 17 sensor channels on the 40-pin variant, sufficient for small appliance front panels and IoT control surfaces. With sub-100 nA sleep current, battery-powered touch remotes and wireless switches become practical using the Q10 as a touch-only front end.

🏭

Industrial Sensor Node

The PIC18F45Q10-E/P's 5V-tolerant I/O and 1.8V-5.5V supply range suit 24V-bus industrial sensors that step down to a regulated 5V rail, providing higher noise immunity than 3.3V-only MCUs. Its 10-bit ADC2 with averaging and filtering delivers oversampled readings for temperature, pressure, and flow sensors without burdening the CPU, while EUSART and MSSP peripherals link to RS-485 transceivers and I2C sensor front-ends. The extended -40C to +125C temperature grade supports outdoor or under-hood deployments without additional thermal qualification.

🏭

Small Motor / Fan Driver Companion

The PIC18F45Q10-E/P's Complementary Waveform Generator (CWG), 16-bit PWM with capture/compare, and Configurable Logic Cells (CLC) make it a flexible companion controller for small BLDC, brushed-DC, or stepper motor driver boards. The CWG provides hardware dead-band control and auto-shutdown on fault, reducing firmware latency in safety-critical motion stops, while the CLC can implement encoder quadrature decoding without software overhead. Operating from 1.8V-5.5V, it accepts direct logic-level commands from a higher-level controller or runs standalone with sensor feedback.

📱

Low-Power IoT End Node

The PIC18F45Q10-E/P's nanoWatt XLP technology delivers sub-100 nA typical sleep current with RTCC and watchdog active, enabling multi-year battery life in IoT end nodes that wake briefly to take a sensor reading and transmit. The on-chip 64MHz HFINTOSC eliminates an external crystal for cost-sensitive nodes, while the MSSP peripheral drives SPI or I2C radios and sensors directly. Combined with the FuSa library, the Q10 also targets utility metering edge nodes where IEC 60730 class B is increasingly required.

📺

Consumer White Goods Control Board

The PIC18F45Q10-E/P is widely deployed in entry-level white-goods control boards (cooktops, microwave ovens, range hoods, small kitchen appliances) because its 5V I/O directly drives triac opto-couplers and seven-segment LED displays without level shifters. The CVD touch peripheral supports sleek glass-front interfaces, while the class B FuSa documentation accelerates safety certification for household appliances sold in regulated markets. With 32KB FLASH and ample CIPs, the Q10 consolidates what previously required a touch IC plus a main MCU plus discrete logic into a single chip.

The PIC18F45Q10-E/P is supplied in a 40-pin PDIP (Plastic Dual In-line Package) with through-hole leads, designated by the /P suffix per Microchip ordering nomenclature. The PDIP-40 footprint is 0.600 inch (15.24 mm) wide, fits standard 0.100 inch (2.54 mm) pitch through-hole pads, and is ideal for breadboarding, hand-soldered prototypes, evaluation fixtures, and legacy industrial backplanes that prefer THT components over SMT.
Does PIC18F45Q10-E/P support functional safety for IEC 60730 Class B?
Yes, the PIC18F45Q10 belongs to Microchip's Functional Safety (FuSa) product family, meaning it ships with supporting safety documentation, FMEDA, and self-test libraries sufficient for IEC 60730 class B compliance in household appliances such as washing machines, dishwashers, ovens, and refrigerators. The Q10 family integrates hardware diagnostics including clock-loss detection, brown-out reset (BOR), windowed watchdog, and RAM/FLASH self-test BIST that are required class B safety functions.
What is the operating voltage range of PIC18F45Q10-E/P?
The PIC18F45Q10-E/P operates from 1.8 V to 5.5 V supply, enabling direct interfacing with 5V logic families, 3.3V peripherals, and battery cells down to a single Li-Ion discharged cell. This wide range is a key differentiator vs 3.3V-only MCUs such as the PIC18F46K22, because the Q10's 5V I/O tolerance simplifies noise-immunity designs in industrial settings. The device includes an internal voltage regulator and POR/BOR for robust startup behavior.
What is the difference between PIC18F45Q10-E/P and PIC18F45Q10-I/P?
The PIC18F45Q10-E/P carries the -E (Extended) temperature grade of -40 C to +125 C, while the PIC18F45Q10-I/P carries the -I (Industrial) grade of -40 C to +85 C. Both share identical silicon, 32KB FLASH, 64MHz core, and 40-PDIP package. Choose the -E/P variant for harsh-environment applications such as under-hood automotive subsystems, outdoor sensor nodes, or industrial machinery, and the -I/P variant for typical consumer/indoor equipment.

PIC18F45Q10-E/P vs PIC18F46Q10-E/P - which is better for higher memory?
The PIC18F45Q10-E/P has 32KB of FLASH and the PIC18F46Q10-E/P has 64KB of FLASH, both in the same 40-pin PDIP package and same Q10 silicon family. If your firmware exceeds 32KB (typical when including graphics libraries, BLE stacks, or class B diagnostic routines), the PIC18F46Q10-E/P is the better choice. For applications under 32KB, the PIC18F45Q10-E/P offers a lower cost and the same 5V-tolerant peripheral set, making it more cost-efficient.
What is the best drop-in replacement for PIC18F45Q10-E/P?
The closest drop-in alternative in the same 40-pin PDIP package is the PIC18F45Q10-I/P (Industrial temperature grade -40C to +85C, otherwise identical silicon). Within Microchip's Q10 family the PIC18F45K42-E/P shares the 40-PDIP footprint and offers upgraded peripherals but at a different memory size; designers should validate pin-by-pin compatibility against the device datasheet before committing. For IEC 60730 class B applications, the FuSa documentation is part-specific and not automatically inherited.
When should I choose PIC18F45Q10-E/P over PIC18F45K22-E/P?
Choose the PIC18F45Q10-E/P when you need 5V-tolerant I/O, Functional Safety (FuSa) documentation for IEC 60730 class B, ADC with Computation (ADC2), or Capacitive Voltage Divider (CVD) for touch sensing. Choose the PIC18F45K22-E/P when you want a mature, broadly available mid-range MCU with similar FLASH size and the legacy 8-bit PIC18 ecosystem. The Q10 adds modern CIPs (CLC, CWG) and nanoWatt XLP at the cost of a slightly newer (less legacy) toolchain experience.
Is PIC18F45Q10-E/P suitable for touch-sensing applications?
Yes, the PIC18F45Q10-E/P integrates ADC2 with Capacitive Voltage Divider (CVD) hardware support, enabling robust capacitive touch-sensing user interfaces such as buttons, sliders, and proximity sensors without an external touch IC. Microchip provides the mTouch CVD library and the MCC code configurator plug-in to streamline button/slider development. The CVD peripheral offloads timing-critical charge balancing to hardware, reducing CPU wake events and enabling low-power touch wake-up from sleep.
Where to download PIC18F45Q10-E/P datasheet PDF?
The official PIC18F45Q10-E/P datasheet (document 40002066E, PIC18F26/45/46Q10 family datasheet) can be downloaded directly from Microchip's website at https://ww1.microchip.com/downloads/en/DeviceDoc/PIC18F26-45-46Q10-Data-Sheet-40002066E.pdf. The same PDF is mirrored at LCSC's datasheet portal (C648022.pdf). The datasheet covers electrical characteristics, memory map, peripheral configurations, and package dimensions for the entire 28/40/40-pin Q10 sub-family.
What are the key specifications of PIC18F45Q10-E/P that engineers should know?
Key specifications for design-in are: 8-bit PIC18 core at 64 MHz / 16 MIPS, 32 KB self-programmable FLASH, 5V-tolerant I/O from a 1.8V-5.5V supply, 40-pin PDIP package, -40C to +125C extended industrial temperature, 10-bit ADC with Computation (ADC2) and CVD, two EUSARTs, two MSSP (I2C/SPI), 16-bit PWM with multiple capture/compare, Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), nanoWatt XLP sleep modes below 100 nA, and Functional Safety (FuSa) documentation for IEC 60730 class B.
What is the best equivalent from STMicroelectronics for PIC18F45Q10-E/P?
A close cross-brand equivalent is the STMicroelectronics STM8S105K4 or STM8S105C6 in a similar 32/48-pin package, but these use a different core architecture (STM8 vs PIC18), so they are NOT drop-in compatible. For true 40-pin PDIP drop-in across brands, the options are extremely limited because Microchip's PIC18 pinout is unique. Designers seeking cross-brand replacements should expect firmware porting effort and pin-by-pin PCB verification rather than relying on footprint equivalence alone.

주요 차별점

  • Functional Safety (FuSa) IEC 60730 Class B documentation (vs PIC18F45K22-E/P)
  • ADC with Computation (ADC2) and Capacitive Voltage Divider (CVD) (vs PIC18F45K42-E/P)
  • Wide 1.8V-5.5V supply range with 5V-tolerant I/O (vs PIC18F45K80-E/P)

설계 노트

Place a 100 nF ceramic decoupling capacitor as close as possible to every VDD pin (pins 11 and 32 on the 40-PDIP package) and add a single bulk 10 uF tantalum or ceramic capacitor on the main supply rail. For battery-powered designs, route the BOR (brown-out reset) configuration to match the lowest expected battery voltage (typically 1.8V-2.0V) to avoid spurious resets as cells age. nanoWatt XLP sleep modes pull < 100 nA with RTCC active, but check the specific datasheet sleep current table for your chosen configuration before finalizing the power budget.

For through-hole PDIP-40 designs, allocate at least a 0.100 inch (2.54 mm) pitch row of 40 through-hole pads on a 0.600 inch (15.24 mm) wide footprint. Reserve a 5-pin header (VPP/MCLR, PGD, PGC, VSS, VDD) for ICSP programming and in-circuit debugging; the RB6/RB7 pins on the PIC18F45Q10 share with the ICSP clock/data lines, so wire them with a small series resistor if the application also drives them as outputs to avoid contention with the programmer. Keep crystal traces short and surrounded by a ground guard ring if accuracy-sensitive timing is required.

Do not confuse the -E (Extended -40C to +125C) and -I (Industrial -40C to +85C) temperature grades - they are part of the ordering suffix and must be specified correctly for harsh-environment designs. When migrating code from a PIC18F45K22 to a PIC18F45Q10, verify the ADC configuration register names because the Q10 introduces the ADC2 (with Computation) registers that differ from the legacy K22 ADC. Always check the Interrupt-on-Change (IOC) edge configuration for PORTB; the Q10 allows both rising and falling edges independently, but firmware migrating from older PICs may not initialize both edges correctly.
