PIC18LF45K42-E/MV - 8-bit 64MHz XLP MCU 32KB Flash UQFN-40 | Microchip

The Microchip Technology PIC18LF45K42-E/MV is an 8-bit PIC® XLP™ 18K microcontroller running at up to 64 MHz with 32 KB Flash, 2 KB SRAM and 256 B EEPROM, housed in a 40-pin UQFN (5x5 mm) MV package. The 'LF' prefix denotes the low-voltage (1.8–3.6 V) variant and the 'E' suffix denotes the -40 °C to +125 °C extended operating range. Core Independent Peripherals (CIPs), on-chip DMA, vectored interrupts, 12-bit ADC2, DAC, comparators, PWM, CWG, HLT, WWDT, SCAN/CRC, ZCD, PPS, UART, SPI and I²C are integrated on die. An 8-bit PIC microcontroller is a Harvard-architecture MCU built around an enhanced RISC core with separate program and data buses, optimized for deterministic interrupt latency and low-power embedded control. It sits inside the broader taxonomy: microcontroller -> embedded MCU -> 8-bit MCU -> PIC18 family -> PIC18F/LF K42 sub-family -> semiconductor. PIC18 K42 devices extend this lineage with on-chip DMA and rich CIP analog blocks aimed at sensor and motor-control applications. Key features include 64 MHz internal oscillator (no external crystal required), 1.8–3.6 V VDD operation, XLP nanoWatt sleep currents below 50 nA typical, and an integrated 12-bit ADC with up to 35 analog channels and automated ADC sequencing. The on-chip DMA engine moves data between peripherals and memory without CPU intervention, offloading high-throughput peripherals like the ADC, UART and SPI. The Peripheral Pin Select (PPS) module allows remapping of digital I/O to a wide set of physical pins, simplifying PCB routing. Typical applications include low-power IoT sensor nodes that benefit from XLP sleep currents, industrial sensor signal conditioning using the 12-bit ADC2 + op-amp + DAC chain, automotive body and HVAC modules in the extended-temperature range, and USB/HID or general-purpose USB bridging with the MSSP module. The 40-pin UQFN footprint exposes 36 I/O pins for keypad, LCD, or display matrix interfaces. When designing with this device, place decoupling 100 nF and bulk 1–10 µF ceramic capacitors as close as possible to VDD/AVDD/VSS pairs, and connect all unused I/O pins to defined logic levels to minimize current leakage in sleep. The PPS configuration registers must be unlocked and locked in a specific sequence to prevent accidental remapping, as detailed in the datasheet configuration word section.

PIC18LF45K42-E/P

PIC18LF45K42-E/P - 32KB Flash, 64MHz 8-bit MCU | Microchip

The Microchip Technology PIC18LF45K42-E/P is an 8-bit PIC microcontroller in the PIC18F K42 family featuring 32KB Flash program memory, 2KB RAM, and 256B EEPROM, housed in a 40-pin PDIP (DIP-40) through-hole package. It operates from a wide 1.8V to 3.6V supply with a 64MHz internal oscillator, integrates a 12-bit ADC2 with Computation (ADCC), vector interrupts, DMA, MAP, DIA, DAC, comparators, PWM, CWG, HLT, WWDT, SCAN/CRC, ZCD, and PPS peripheral pin select. A microcontroller (MCU) is a single-chip computer containing a CPU core, volatile and non-volatile memory, programmable peripherals, and I/O pins. The PIC18 family from Microchip is built on an enhanced 8-bit Harvard RISC architecture optimized for deterministic real-time control, while the LF suffix denotes the low-voltage F-family variant aimed at battery and energy-harvesting applications. This part belongs to the broader hierarchy: microcontroller -> 8-bit MCU -> PIC18 -> PIC18F K42 sub-family -> low-power (LF) line -> 40-pin segment. Key differentiating features include the 12-bit ADCC with automatic averaging and threshold comparison offloading CPU cycles, the Direct Memory Access (DMA) controller that moves data between peripherals and memory without CPU intervention, and the Peripheral Pin Select (PPS) which remaps digital I/O functions to virtually any pin. The device also includes Zero-Cross Detection (ZCD), Complementary Waveform Generator (CWG), and Windowed Watchdog Timer (WWDT) for safety-critical loop timing. A 32KB self-programmable Flash supports bootloaders and field firmware updates. Architecturally the K42 family uses Microchip's eXtreme Low Power (XLP) technology with typical sleep currents in the nanoamp range and multiple IDLE/DOZE/PMD power-management modes. The 64MHz maximum clock derives from a 16MHz internal oscillator with a 4x PLL, and the device supports instruction-cycle throughput of 16 MIPS at 64MHz. Core-independent peripherals (CIPs) such as CWG, NCO, and PWM allow complex waveform synthesis with zero CPU involvement. Typical applications include low-power IoT sensor nodes running on coin-cell batteries, home-automation and HVAC control units, LED lighting controllers with smooth dimming, USB-to-UART bridge devices, industrial sensor conditioning with 12-bit ADC acquisition, and motor-control signal conditioning using the CWG and PWM peripherals. The wide operating voltage range and XLP features also suit portable medical and metering instruments. When designing with this MCU, plan for ICD/ICSP header access on every prototype to support in-circuit debugging via Microchip's MPLAB X IDE. The PPS system must be configured in firmware before peripheral use; failure to do so will leave pins floating. Finally, verify the 64MHz core speed against the chosen low-voltage mode - maximum frequency drops at lower Vdd.

PIC18LF45K42-E/PT

PIC18LF45K42-E/PT - 8-bit 64MHz 32KB Flash MCU 44-TQFP | Microchip

The Microchip PIC18LF45K42-E/PT is an 8-bit PIC18 microcontroller built on the eXtreme Low Power (XLP) platform, featuring a 64 MHz CPU, 32 KB of Flash program memory, 2 KB of SRAM, and 256 bytes of EEPROM, housed in a 44-pin TQFP (10x10 mm) package. It integrates a rich set of Core Independent Peripherals (CIPs) including a 12-bit ADC with Computation (ADCC), a 5-bit DAC, configurable logic cells, complementary waveform generators, and zero-cross detection, all operating over a wide 1.8V to 5.5V supply range. The 'LF' prefix denotes the low-voltage/F-version silicon that supports full-speed operation across the entire supply range with nanoWatt XLP sleep currents below 50 nA typical. An 8-bit microcontroller (MCU) is a single-chip computer that integrates an 8-bit CPU, program memory (Flash), data memory (SRAM), non-volatile storage (EEPROM), and a configurable peripheral set. PIC18 microcontrollers use a 16-bit instruction word with an 8-bit data path, placing them in the hierarchical taxonomy: microcontroller -> embedded controller -> semiconductor IC. The PIC18F/LF K42 family specifically targets applications that require complex analog signal conditioning, deterministic hardware-driven responses, and very low standby power for battery-backed designs. Key differentiating features include the Direct Memory Access (DMA) controller that moves data between memory and peripherals without CPU intervention, peripheral pin select (PPS) for flexible signal routing, vectored interrupts for fast deterministic response, and a 12-bit ADCC with automated averaging, oversampling, and threshold comparisons. These features allow software state machines to be offloaded to hardware, reducing CPU load and code size while improving real-time performance. The 256-byte EEPROM and 2 KB SRAM support 32 KB of Flash code with room for data logging tables and communication buffers. The architecture uses a modified Harvard layout with a hardware multiplier and a 31-level stack, supporting C-compiled code via the XC8 toolchain. Four 16-bit timers, multiple CCP/PWM modules, two I2C, two SPI, two UART (with LIN), and a 12-bit differential ADC make it suitable for mixed-signal embedded designs that need both analog precision and digital throughput. The on-chip DMA engine can autonomously feed the ADC into RAM, freeing the core to manage the control loop. Typical applications include industrial sensor transmitters, low-power IoT edge nodes, BLDC motor control stages, automotive body and lighting ECUs (non-safety), home appliance user-interface and motor controllers, and battery-powered metering products. The combination of nanoWatt XLP idle modes, high-resolution analog, and DMA is particularly well matched to handheld instrumentation and remote sensor nodes that spend most of their life in sleep. Design consideration: leverage DMA to pre-fill ADC result buffers in sleep, then wake on threshold or interrupt - this combination minimizes average current without sacrificing measurement cadence. Be careful to configure the PPS mappings for every digital peripheral before first use to avoid floating or shorted outputs during code bring-up.

For instance, the integrated 10-bit ADC and 36 I/O lines enable direct interfacing with analog sensors, keypads, and LEDs in a single-chip solution. Designers should budget for the exposed pad's thermal dissipation path - the e-pad must be soldered to a grounded copper pour for electrical and thermal performance. The wide voltage range allows direct Li-ion battery operation between 2.5V and 4.2V without an LDO, simplifying portable designs.

PIC18LF4620-I/P - 8-bit 40MHz MCU 64KB Flash 40-PDIP | Microchip
PIC18LF4620-I/P

PIC18LF4620-I/P - 8-bit 40MHz MCU 64KB Flash 40-PDIP | Microchip

The Microchip Technology PIC18LF4620-I/P is an 8-bit PIC18F-family microcontroller based on the RISC architecture, integrating 64KB of Flash program memory, 3968 bytes of RAM, and 1024 bytes of EEPROM in a 40-pin PDIP (DIP-40) through-hole package. It executes instructions at up to 40 MHz (10 MIPS), operates from a wide 2.0V-5.5V supply, and exposes 36 digital I/O lines plus a 10-bit ADC, multiple timers, USART, MSSP (I²C/SPI), and the Enhanced Nano Watt-CEE family of nanoWatt or low-power modes. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, peripheral I/O, and clock generation on one die. The PIC18 family sits in the broader taxonomy: microcontroller -> embedded processor -> semiconductor -> integrated circuit. Within 8-bit MCUs, PIC18 devices are typically classified by their high-endurance Enhanced Flash memory, hardware multiplier, and C-friendly architecture. The LF suffix denotes the low-voltage variant that supports operation down to 2.0V, enabling battery-powered and 3.3V designs. Key features include 64KB (32K x 16) of self-programmable Flash, 3968 bytes of SRAM, 1024 bytes of EEPROM data memory, 36 I/O pins with individual direction control, 13 channels of 10-bit ADC, two 8-bit and three 16-bit timers, two capture/compare/PWM modules, Enhanced USART, MSSP supporting SPI and I²C (Master/Slave), two analog comparators, and a hardware 8x8 multiplier. The nanoWatt technology provides power-managed modes including Idle, Sleep, and a low-power Timer1 oscillator for RTC operation. The architecture uses a 16-bit instruction word with an 8-bit data path and a hardware multiply engine that executes an 8x8 unsigned multiply in a single instruction cycle. The Enhanced Flash supports ICSP (In-Circuit Serial Programming) and self-programming under firmware control, allowing field updates and bootloader designs. The 2.0V minimum supply opens the LF4620 to single-cell Li-ion or 2x AA alkaline applications while remaining drop-in compatible with the 5V PIC18F4620 (which requires 4.2V-5.5V). Typical applications include industrial control panels, sensor signal conditioning, USB-to-UART bridges, HVAC thermostats, automotive body electronics, home appliances, and general-purpose embedded control boards. The 40-pin PDIP package supports hand-prototyping, breadboard use, and educational platforms, and is favored in through-hole designs where socketed or replaceable parts are required. When designing with this part, note that the LF and F variants differ only in VDD range (2.0V-5.5V vs 4.2V-5.5V); firmware written for one generally runs on the other. The 40-MHz oscillator can be driven from an external source or ceramic resonator; for RTC accuracy, a 32.768-kHz crystal on Timer1 is recommended. Ensure MCLR is tied to VDD through a 10 kΩ pull-up for normal operation.

PIC18LF4620-I/PT

PIC18LF4620-I/PT - 8-bit 40MHz 64KB Flash MCU | Microchip TQFP-44

The Microchip Technology PIC18LF4620-I/PT is an 8-bit PIC18 enhanced flash microcontroller with 64KB program memory, 40MHz CPU clock, and 36 I/O pins, housed in a 44-pin TQFP (10x10 mm) package. The "LF" variant operates from 2.0V to 5.5V, suiting battery-powered and low-voltage designs, while the "F4620" integrates 64KB Flash, 3968 bytes RAM, 1024 bytes EEPROM, a 10-bit ADC, and nanoWatt power management for energy-sensitive applications. An 8-bit microcontroller (MCU) is a programmable processor that executes instructions 8 bits at a time and combines CPU, memory (Flash, RAM, EEPROM), peripherals (ADC, timers, UART, SPI, I2C, PWM), and I/O on a single silicon die. PIC18 microcontrollers occupy the high-performance tier of Microchip's 8-bit portfolio, sharing the PIC architecture lineage with PIC16 and PIC24/dsPIC families and targeting embedded control products where deterministic execution and low power matter more than raw MIPS. Within this hierarchy, PIC18LF4620 belongs to the F46xxx K-class subfamily that adds USB, CAN, and enhanced peripherals. Key features include 64KB (32K x 16 words) self-programmable flash, 3968 bytes SRAM, 1024 bytes EEPROM, 13 ADC channels with 10-bit resolution, two comparators, two 8-bit timers and three 16-bit timers, two MSSP (SPI/I2C) and two EUSART ports, and nanoWatt technology that drops Iq below 100 nA in sleep mode. The 44-pin TQFP footprint and wide operating temperature range (-40C to +85C industrial grade) make it suitable for through-hole-replacement SMD designs. The PIC18LF4620-I/PT uses an enhanced Harvard architecture with a 16-bit instruction word and 8-bit data path, allowing single-cycle 8x8 hardware multiply and single-cycle 16-bit fetch. The 40MHz internal clock drives 10 MIPS throughput, with 4x PLL options. nanoWatt dynamic clock switching lets the firmware trade MIPS for power at run-time. Master Clear, in-circuit serial programming (ICSP), and in-circuit debugger (ICD) interfaces are all retained on dedicated pins. Typical applications include industrial sensor conditioning, USB HID peripherals, automotive body controllers, HVAC control panels, low-power remote sensing, and small appliances. With 36 I/O, the device can drive multiple keypads, LED matrices, or relays without external expanders. When laying out, allocate the ICPG/ICPG clock pins away from PWM traces to avoid coupling, and place the 0.1uF Vdd decoupling within 5mm of each Vdd pin. An external 32.768 kHz crystal for Timer1 is recommended when real-time-clock accuracy matters.

The PIC18 family uses a 16-bit instruction word with an 8-bit data path, providing an enhanced instruction set over earlier PIC16 devices while maintaining full code compatibility with the PIC16 mid-range core. The "nanoWatt Technology" branding refers to Microchip's power-management features including multiple idle and sleep modes, oscillator start-up timers, and ultra-low-power Real-Time Clock/Calendar operation. Key features include 64 KB (32 K x 16) flash program memory, 3968 bytes of RAM, 1024 bytes of EEPROM, a 10-bit Analog-to-Digital Converter (ADC) with up to 13 input channels, multiple communication peripherals (EUSART, MSSP for SPI/I2C), and four 8-bit/16-bit timers. The device supports up to 36 digital I/O pins, hardware multiplier, and enhanced Capture/Compare/PWM (ECCP) modules, enabling direct motor control, power-conversion, and lighting applications without external logic. The PIC18LF4620T-I/PT integrates nanoWatt power-management technology with multiple low-power modes (RUN, IDLE, SLEEP) and a fast wake-up from sleep with 1 µs typical response. The internal RC oscillator and PLL options support flexible clock configurations from 31 kHz to 40 MHz. The architecture also supports in-circuit serial programming (ICSP) and in-circuit debugging (ICD) via MPLAB tools, allowing field firmware upgrades and real-time development. Typical applications include industrial automation controllers, automotive body electronics, USB peripherals, sensor signal conditioning, smart-card readers, and consumer appliances. The wide voltage range (2.0 V to 5.5 V) makes it particularly well suited to battery-powered devices such as portable instrumentation and remote sensors. The 64 KB flash provides sufficient code space for graphical user interfaces, protocol stacks (Modbus, LIN), and over-the-air (OTA) firmware update routines. When designing with this device, consider using the PIC18F4620 (5 V only) variant for cost-sensitive line-powered designs, or PIC18LF45K80 (lower power with enhanced peripherals) for battery applications. Always consult the PIC18F4620 family datasheet for ADC acquisition-time calculations, MSSP timing margins, and CCP PWM resolution trade-offs at system clock frequencies above 25 MHz.

The Microchip Technology PIC18LF4680-I/ML is a low-power 8-bit PIC18 microcontroller with 64 KB of Flash program memory and an integrated Enhanced CAN (ECAN) module, housed in a 44-pin QFN (8x8 mm) package. It operates from 2.0 V to 5.5 V and runs up to 40 MHz, targeting cost-sensitive embedded designs that require on-chip CAN, LIN-capable UART, and moderate analog performance. Key features include 64 KB (32K x 16) of self-programmable Flash, 3328 bytes of RAM, 1024 bytes of EEPROM, 11 channels of 10-bit ADC, and 36 digital I/O pins. The LF variant uses an advanced CMOS process with nanoWatt technology, providing low sleep current and idle current optimizations suited for battery-powered industrial and automotive subsystems. The PIC18F4680 family architecture pairs a 16-bit modified Harvard core with a wide peripheral set: two Enhanced USART modules, MSSP for SPI/I2C, two Capture/Compare/PWM modules, an Enhanced CAN 2.0B controller with hardware filtering, and a 10-bit 11-channel ADC. The ECAN controller implements CAN 2.0A/B with DeviceNet and CANopen filtering capability, removing the need for an external CAN transceiver controller in many node designs. Typical applications include industrial CAN nodes (sensor hubs, motor controllers), automotive body and chassis ECUs, building automation (BACnet or CAN-based HVAC), and medical instrumentation with battery-backed operation. The wide VDD range (2.0 V to 5.5 V) allows direct connection to 3.3 V or 5 V rails and 2-cell Li-ion battery stacks. Designers should pair this MCU with a 3.3 V CAN transceiver such as the MCP2551 or MCP2561 and a precision LDO such as the MCP1700 for the analog supply. A 20 MHz or 40 MHz crystal or resonator is required for CAN-bus synchronization; ECAN bit-timing relies on Fosc accuracy. For firmware development, MPLAB X IDE, XC8 compiler, and MPLAB Code Configurator support code generation for ECAN, ADC, and PWM peripherals.
