The Microchip Technology PIC18F47K40-I/P is an 8-bit PIC18 microcontroller running at up to 64 MHz, integrating 128 KB of Flash program memory, 4 KB of RAM, and 256 bytes of EEPROM in a 40-pin PDIP (DIP-40) through-hole package. The device pairs an enhanced mid-range PIC18 core with the company's XLP (eXtreme Low Power) technology and 5V native I/O tolerance, suiting general-purpose, low-power, and 5V-tolerant designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a rich set of peripherals (ADC, timers, communication interfaces, PWM, comparators). It belongs to the hierarchy: microcontroller -> embedded processor -> semiconductor IC -> electronic component. PIC18F-series MCUs sit in Microchip's 8-bit mid-range tier and target cost-sensitive, deterministic, low-power applications where an ARM Cortex-M device would be over-specified. Key features include 10-bit ADC with computation (ADC2), a 5-bit DAC, comparators, PWM, CCP, the Configurable Logic Cell (CLC), Complementary Waveform Generator (CWG), Windowed Watchdog Timer (WWDT), SCAN/CRC, Zero-Cross Detect (ZCD), Peripheral Pin Select (PPS), EUSART, and SPI/I2C. The XLP technology delivers nanoWatt sleep currents, allowing battery-powered products to retain state for years. The 128 KB Flash and 4 KB RAM enable meaningful embedded firmware with communication stacks and user-interface logic. Peripheral Pin Select remaps digital peripherals to almost any I/O pin, simplifying PCB layout and BOM reuse across the PIC18F4xK40 family. Typical applications include home appliances, white goods, motor-control front ends, sensor hubs, IoT edge nodes, and any 5V-tolerant embedded design. The 40-pin PDIP package is breadboard-friendly and accelerates prototyping and field-replaceable modules. When designing with this MCU, plan oscillator and ICSP pin usage early because pins 38/39 share the debugger; using the PPS system lets designers re-route EUSART/SPI after the schematic is frozen. A 100 nF decoupling capacitor as close as possible to VDD/AVDD plus a 10 µF bulk cap is the minimum recommended power architecture.

XLP Sleep current is typically under 50 nA, allowing battery-powered designs to run for years on a single cell. The 44-pin TQFP is the largest footprint in the K40 family, exposing the maximum peripheral count. Internally the K40 uses a C-optimized RISC core with hardware multiplier and a 16-bit instruction word fetched from Flash. The CPU is supported by a 4-deep stack, indexed addressing modes and a C-friendly peripheral library (MCC code generator). 5V tolerance across digital I/O simplifies interfacing to legacy analog and industrial buses without level shifters. Typical applications include home appliances and white goods, IoT sensor nodes, industrial control panels, USB HID peripherals, motor control with CWG, lighting ballasts, and automotive body modules. The 128 KB Flash also makes it attractive as a platform MCU for consumer products with graphical LCDs. When designing with the K40, plan the analog pin assignments carefully because several CIPs share analog inputs. Decouple VDD with 100 nF + 1 uF near each power pin, keep the ICSP lines accessible for in-circuit programming, and budget for an external 32 kHz crystal only if RTC accuracy below 1% is required.

The CPU executes instructions at up to 64 MHz from the internal 64 MHz oscillator, delivering approximately 16 MIPS of throughput while consuming as little as 30 nA in sleep mode with full RAM retention. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, RAM, and peripheral interfaces on one die. Within the broader taxonomy, a microcontroller belongs to the semiconductor > integrated circuit > microcontroller > 8-bit MCU > PIC18 family of devices. PIC18 MCUs use a modified Harvard RISC architecture and are widely deployed in cost-sensitive embedded control, IoT end-nodes, sensor hubs, and human-machine interface applications where deterministic real-time response and low standby power are essential. The PIC18F47K42-I/P combines 12-bit ADC2 (up to 35 channels with automatic Capacitive Voltage Divider support), 5-bit DAC outputs, three op-amps, two comparators, DMA, vector interrupts, and a Peripheral Pin Select (PPS) mapping engine that lets designers remap digital peripherals to any I/O pin. The 128 KB Flash is partitioned for bootloader and field firmware updates, while the MAP and DIA (Device Information Area) features support unique per-chip serialization and calibration. Operating voltage spans 1.8 V to 5.5 V with active core current below 5 mA at 64 MHz and idle currents under 1 mA. Hardware peripherals include PWM, CWG, NCO, UART, SPI, I2C, and a 32-level hardware stack. The integrated nanoWatt XLP technology enables battery-powered applications such as wireless sensor nodes, wearables, and remote controls where standby drain dominates battery life. Typical applications include IoT sensor nodes, low-power wireless devices, automotive body and interior modules, industrial control panels, consumer appliances, and USB-to-UART bridge firmware platforms. The 40-pin PDIP form factor is especially well suited to prototyping, hobbyist projects, and educational platforms where through-hole soldering and breadboarding are preferred over surface mount. When designing with the PIC18F47K42-I/P, leave VDD/VSS decoupling (100 nF plus 10 µF bulk) within 5 mm of every supply pin, and tie the MCLR pin through a 10 kΩ pull-up to VDD for reliable reset. The PPS configuration registers must be programmed in the user initialization code; otherwise peripherals default to fixed pin assignments.

Typical applications for this part include industrial sensor signal conditioning, LED lighting controllers with smooth dimming, small BLDC/PMSM motor controllers, capacitive touch user interfaces, building automation nodes, and low-power IoT edge nodes. The wide peripheral set reduces external component count and BOM cost. When designing with this MCU, allocate the 40 pins carefully: many peripherals are remappable via PPS (Peripheral Pin Select), but only a subset of pins support PPS output routing. Decouple VDD/VSS pairs with 100 nF ceramic capacitors placed within 5 mm of each pin pair, and provide an analog AVSS/AVDD pair for the ADC/DAC.

PIC18F47Q43T-I/MP - 128KB Flash 8-bit MCU | Microchip

The Microchip Technology PIC18F47Q43T-I/MP is an 8-bit PIC microcontroller operating at up to 64 MHz, with 128 KB Flash program memory, 8 KB SRAM, and 1 KB EEPROM, housed in a 40-pin QFN (5x5 mm) package with tape and reel packaging. It belongs to the PIC18-Q43 family featuring Core Independent Peripherals (CIPs), advanced interconnection capabilities, and Functional Safety (FuSa) support, and is supplied in industrial temperature grade -40C to +85C. What is an 8-bit microcontroller? An 8-bit MCU is a programmable microcontroller that uses an 8-bit data bus as its core processing unit, and belongs to the broader category of microcontrollers -> embedded processors -> semiconductor ICs. Within the PIC18 family, the Q43 line targets functional safety, XLP (eXtreme Low Power), and hardware customization through configurable logic and interconnected CIPs. Compared with 16- or 32-bit MCUs, an 8-bit PIC like the PIC18F47Q43T-I/MP excels in deterministic interrupt response, simple peripheral integration, and very low active and sleep power budgets. Key features include 12-bit ADC2 with computation, 5-bit DAC, comparators with 16-bit PWM, hardware limit timer (HLT), windowed watchdog timer (WWDT), CRC/SCAN, zero-cross detect (ZCD), and Peripheral Pin Select (PPS) that allows most digital I/O to be remapped to a wide range of device pins. The 8-bit PIC18 CPU delivers 64 MHz operation with up to 16 MIPS throughput, while keeping peripheral activity possible in IDLE and DOZE modes. The architecture combines a RISC core with hardware CIP blocks, eliminating many software loops and shrinking firmware size. Functional Safety support (FuSa) and XLP technology with sub-uA sleep currents make the device attractive in safety-critical and battery-powered designs. Internal 64 MHz oscillator accuracy (1% typical) supports both USB-friendly and timing-sensitive implementations without an external crystal. Typical applications include industrial sensor conditioning nodes, IoT edge nodes with secure boot, automotive body and accessory modules, consumer appliances with HMI control, low-power motor and LED drivers, and medical measurement instrument peripherals. The combination of 128 KB Flash, 8 KB RAM, and rich analog/peripheral mix fits mid-range embedded products. When designing with this device, allocate PCB area for the 40-QFN thermal pad, which must be soldered to the ground plane for thermal and electrical performance. Route the PGC/PGD lines short and shielded for robust in-circuit serial programming (ICSP), and reserve RE3/MCLR as the reset pin with proper external pull-up. This page synthesizes distributor pricing, drop-in alternatives, design notes, and FAQ collected from manufacturer documentation - giving engineers a faster reference than the datasheet alone.

PIC18F47Q83-E/P - 8-bit MCU 128KB Flash CAN DIP-40 | Microchip

The Microchip Technology PIC18F47Q83-E/P is an 8-bit PIC microcontroller from the PIC18-Q83 family, featuring 128 KB of Flash program memory, 13 KB of SRAM, 1 KB of EEPROM, and an integrated Controller Area Network (CAN) peripheral in a 40-pin PDIP through-hole package. It operates at up to 64 MHz across an extended temperature range of -40C to +125C, and integrates a 12-bit ADC3, DAC, DSM (Digital Signal Modulator), multiple PWM channels, and Core Independent Peripherals (CIPs) that offload tasks from the CPU. The 40-pin DIP form factor supports breadboard prototyping and legacy socketed designs. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data-path CPU core with on-chip Flash, RAM, and peripherals. Within the broader semiconductor taxonomy, an MCU belongs to the microcontroller family, which is itself a subset of microprocessors and embedded computing devices. The PIC18-Q83 family extends Microchip's CIP concept - hardware blocks such as CLC, NCO, PWM, DSM, and CRC/SCAN that execute state-machine logic without CPU intervention - to include a CAN FD peripheral, eliminating the need for an external CAN controller. Key features include 36 configurable I/O pins, hardware math accelerator support via CIP, 5 CCP/PWM channels, two UART, two SPI, two I2C, and a 12-bit differential ADC. The integrated CAN FD controller supports ISO 11898-1 and ISO 11898-2, enabling high-throughput industrial and automotive networking. Low-power features include Idle, Doze, and peripheral module disable modes, plus a power-saving Sleep mode with fast wake-up. Typical applications include CAN-based industrial control nodes, automotive body and chassis ECUs, sensor fusion gateways, small-form-factor PLCs, and protocol-conversion bridges. The DIP-40 package is preferred for prototypes, field-replaceable modules, and educational platforms where through-hole soldering is required. When designing with the -E/P variant, observe the 5.5 V maximum VDD rating and use 1% decoupling capacitors within 5 mm of every VDD/VSS pair. The internal 64 MHz HFINTOSC eliminates external crystal cost, but for CAN bus timing accuracy an external crystal is recommended. Migrating from -E/P to -E/PT (TQFP-44) requires no firmware change but PCB layout rework.
