PIC18LF46K42T-I/PT - 8-bit 64MHz 64KB Flash MCU 44-TQFP | Microchip

The Microchip Technology PIC18LF46K42T-I/PT is a low-power 8-bit PIC18 microcontroller running up to 64 MHz with 64 KB (32K x 16) of Flash program memory, housed in a 44-pin TQFP (10x10 mm) package. The LF prefix indicates the wide 1.8 V to 3.6 V operating range suitable for battery-powered designs, while the I suffix denotes the industrial -40C to +85C temperature grade and T designates Tape and Reel packaging. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (RAM), non-volatile data storage (EEPROM), and a rich set of peripherals such as timers, ADC, DAC, communication interfaces, and GPIO into one IC. Within the broader taxonomy, an MCU belongs to the family of embedded processors -> microcontrollers -> 8-bit microcontrollers. The PIC18LF46K42 sits inside Microchip's XLP (eXtreme Low Power) family, designed for applications where nanoWatt sleep currents and active-mode efficiency both matter; the same family also includes complementary parts such as PIC18F46K42 with 2.3V-5.5V VDD range. Key features of the PIC18LF46K42T-I/PT include 64 KB self-programmable Flash, 4 KB SRAM, 1 KB EEPROM, a 12-bit ADC with computation, multiple DMA-capable peripherals, and configurable logic cells. The integrated 64 MHz internal oscillator eliminates an external crystal in many designs, and the device supports Core Independent Peripherals (CIPs) that offload tasks from the CPU. The 44-TQFP package exposes 36 GPIO lines, ample for human-machine interfaces, sensor aggregation, or motor control front-ends. Architecturally, the PIC18FxxK42 family uses an enhanced Harvard architecture with a 16-bit instruction word and 8-bit data path, delivering deterministic interrupt latency and efficient C compilation under MPLAB XC8. The peripheral set includes multiple UART, SPI, I2C, PWM, comparator, and op-amp modules, plus a 5-bit DAC and zero-cross detection. DMA channels service ADC and communication peripherals, enabling the CPU to remain in sleep until meaningful events occur - a key XLP differentiator. Typical applications include IoT sensor nodes, home automation controllers, battery-powered medical wearables, industrial telemetry, white-goods user interfaces, and low-cost BLDC/PMSM motor control boards. The combination of XLP sleep modes (down to ~50 nA typical) and DMA-driven peripherals makes the device especially suited to energy-harvesting or replaceable-battery products where quiescent current dominates total energy budget, plus AEC-Q100 variants exist in the F-series for automotive body and chassis ECUs. When designing with this MCU, ensure the configuration bits are correctly set for the chosen oscillator source and brown-out reset threshold; Microchip's MPLAB Code Configurator (MCC) generates the initialization code automatically. Place a 100 nF decoupling capacitor on every VDD/VDDIOX pair, keep analog reference traces short, and reserve the ICSP pins (PGC/PGD) for in-circuit programming access.

PIC18LF46K80-I/ML

PIC18LF46K80-I/ML - 8-bit 64MHz 64KB Flash MCU w/ ECAN | Microchip

The Microchip Technology PIC18LF46K80-I/ML is an 8-bit RISC PIC18 microcontroller with integrated ECAN, 64 KB Flash, 3648 B RAM, and 1024 B EEPROM, housed in a 44-pin QFN (8x8 mm) package. It operates from 1.8 V to 3.6 V (LF low-voltage family) at up to 64 MHz (16 MIPS) and includes 11 channels of 12-bit ADC, 5 PWM channels, dual EUSART, MSSP (SPI/I2C), and the nanoWatt XLP extreme-low-power technology. An 8-bit PIC microcontroller is a Harvard-architecture CMOS device that executes one instruction per clock cycle (except branches) using a reduced instruction set. PIC18 devices sit at the top of Microchip's 8-bit portfolio, offering 16-bit wide instructions, up to 64 KB of linear-addressable Flash, and rich peripheral integration. They occupy the hypernym hierarchy: microcontroller -> MCU -> embedded microcontroller -> 8-bit MCU -> PIC18 family -> ECAN-enabled PIC18 sub-family, and are widely used as deterministic, low-cost system controllers in industrial, automotive body, and consumer products. Key features of the PIC18LF46K80 include hardware ECAN 2.0B with full CAN 2.0B active compliance, an 11-channel 12-bit A/D converter with acquisition timer, 5 PWM modules with dead-band control, two enhanced USARTs supporting RS-485 and LIN master, and a master SSP supporting SPI and I2C (master/slave). The device is rated for -40 C to +85 C industrial operation and supports nanoWatt XLP modes with sleep currents below 100 nA typical, enabling battery-backed or energy-harvested designs. The LF (low-voltage) silicon is optimized for 1.8 V-3.6 V operation, which trades absolute speed and analog headroom for dramatically lower power than the 5 V PIC18F46K80 counterpart. Designers moving between the two must verify analog supply and I/O voltage compatibility, since the LF variant cannot directly interface 5 V peripherals without level shifters. The integrated ECAN, 12-bit ADC, and 5 PWM channels make this part a single-chip solution for sensor-rich nodes and small motor-control loops. Typical applications include automotive body modules and CAN nodes (HVAC, lighting, seat controllers), industrial sensor hubs with ECAN backbone, building automation (BACnet over CAN, elevator controllers), low-power remote sensor nodes with CAN connectivity, and LIN-to-CAN gateway bridges. The combination of nanoWatt XLP sleep modes and integrated ECAN makes it particularly attractive for always-on, bus-powered nodes that must wake on CAN traffic and process interrupts while drawing microamp-level quiescent current. Design considerations include providing a stable 1.8 V-3.6 V rail (decoupling 100 nF + bulk cap adjacent to the QFN thermal pad), connecting the exposed pad to ground for thermal dissipation, and configuring the MCLR pin for proper in-circuit serial programming (ICSP). For high-CAN-bus loads, add a TVS diode and proper bus bias network to meet ISO 11898 ESD/EMC requirements.

It features nanoWatt XLP technology with typical sleep currents of <100 nA and Run currents of approximately 7 mA at 4 MHz. The CTMU peripheral enables capacitive touch buttons, sliders, and proximity sensing without external components. The architecture uses a 2-stage pipeline with single-cycle instruction execution at 64MHz (16 MIPS), a hardware multiplier, C-compiler-optimized instruction set, and a priority-level interrupt controller. The 64KB Flash is self-programmable under firmware control (ICSP) and supports bootloader operation. ECAN supports CAN 2.0B active with hardware acceptance filters, providing automotive-grade bus connectivity. Typical applications include industrial CAN nodes, automotive body and comfort modules, building automation, capacitive touch human-machine interfaces, sensor hubs with analog front-ends, and low-power remote battery-powered monitoring. The integrated ECAN and XLP make it particularly suited for sleep-dominated networks such as automotive LIN/CAN gateways and HVAC controllers. Design consideration: when migrating between 'LF' (1.8V-3.6V) and 'F' (1.8V-5.5V) variants, verify that any 5V peripherals are tolerant of the lower VDD. ECAN bus termination (120 ohm) must be placed at each end of the bus segment. For CTMU touch sensing, PCB layout guidelines from Microchip AN1250 should be followed.

The Microchip Technology PIC18LF55K42-E/PT is an 8-bit PIC18 microcontroller from the PIC XLP 18K family, offering 32KB Flash program memory, 2KB RAM, and 256B EEPROM in a 48-pin TQFP-EP (7x7 mm) package with extended operating temperature range. The device integrates a 12-bit ADC2 module, vector interrupts, DMA controller, MAP (Memory Access Partitioning), DIA (Device Information Area), DAC, comparators, and multiple PWM channels on-chip. An 8-bit microcontroller (MCU) is a small computer-on-a-chip built around an 8-bit data bus. It sits within the broader hierarchy of microcontrollers -> embedded processors -> integrated circuits -> semiconductors. The PIC18 family specifically targets high-performance 8-bit applications requiring C-friendly architecture, hardware DMA, and rich peripheral integration. Low-power 'LF' variants like this one extend operating voltage down to 1.8V for battery-powered designs, where XLP (eXtreme Low Power) technology enables nanoWatt sleep currents. Key features of the PIC18LF55K42-E/PT include 64 MHz maximum CPU clock, 44 configurable I/O pins, an integrated 12-bit ADC2 with computation, hardware DMA for memory-to-memory and memory-to-peripheral transfers, multiple communication peripherals (I2C, SPI, UART/USART), and enhanced PWM with complementary outputs. The -E temperature grade extends operation from -40C to +125C for industrial and harsh-environment applications. The PIC18 core employs a Harvard architecture with a 16-bit instruction word and 8-bit data path, providing C-friendly addressing and deterministic interrupt latency. Core-independent peripherals such as the CWG (Complementary Waveform Generator), NCO (Numerically Controlled Oscillator), and hardware DMA offload the CPU, allowing complex control loops to run without software intervention. The MAP memory scheme provides separate boot and secure flash regions for bootloader and IP protection. Typical applications for the PIC18LF55K42-E/PT include industrial sensor nodes, motor control (BLDC and stepper), IoT edge devices, LED lighting controllers, consumer appliance control, and battery-powered instrumentation. The 32KB flash and DMA support make it suitable for protocol stacks such as Modbus, LIN, and basic BLE bridging when paired with an external radio. When designing with this device, pay attention to decoupling (place 100nF + 1uF near VDD pins), unused-pin tie-off (drive or pull per datasheet), and ICP/ICD programming pin allocation. The 'LF' variant requires VDD between 1.8V and 3.6V, so an LDO or buck converter is required for 5V systems.

PIC18LF55K42-I/PT - 8-Bit 64MHz MCU 32KB Flash TQFP-48 | Microchip

The Microchip Technology PIC18LF55K42-I/PT is a low-power 8-bit PIC18 microcontroller from the PIC18F/LF55K42 family, integrating 32KB of Flash program memory, 2KB of SRAM, and 256 bytes of EEPROM in a 48-pin TQFP-EP (7x7 mm) package. The device operates from a wide 1.8 V to 5.5 V supply, runs at up to 64 MHz internal clock, and features 44 general-purpose I/O pins plus a rich peripheral set including a 12-bit ADC2 with Computation, two 8-bit DACs, comparators, PWM, DMA, vector interrupts, and Core Independent Peripherals (CIPs) such as the Configurable Logic Cell (CLC) and Signal Measurement Timer (SMT). A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (Flash), working memory (RAM), data EEPROM, and a set of on-chip peripherals into a single chip, enabling compact embedded designs without external glue logic. The PIC18 architecture is an 8-bit RISC core with hardware multiplier, 16-bit instructions, and an instruction set optimized for deterministic real-time control, suitable for consumer appliances, industrial sensors, automotive body electronics, and battery-powered IoT edge nodes. Key features include the XLP (eXtreme Low Power) technology for sub-uA sleep currents, the Peripheral Pin Select (PPS) cross-switch for routing digital peripherals to almost any I/O, and an integrated 32 MHz internal oscillator accurate to within +/-1% across temperature. The ADC2 with Automated Accumulation and Burst Average modes can offload averaging from the CPU, while the DMA controller moves data between peripherals and RAM without core intervention, allowing the device to remain in Sleep for extended battery operation. The 48-pin TQFP-EP package provides an exposed thermal pad to reduce junction-to-ambient thermal resistance, which is useful for industrial and automotive under-hood designs where continuous ADC sampling and PWM output at full CPU load raises the die temperature. The -I/PT suffix denotes the Industrial temperature grade (-40C to +85C) supplied in Tray packaging. Typical applications include HVAC thermostat controllers, white-goods user interfaces, battery-powered sensor hubs, USB-to-UART bridges, small motor control boards, and human-machine interface panels. The combination of 32KB Flash and 2KB RAM is comfortable for mid-size state machines, Modbus slave firmware, and graphical OLED menu stacks. Compared with newer PIC18FxxQ-series parts the LF55K42 is the lower-power (LF) variant optimized for 3.3V or 1.8V rails, while the PIC18F55K42 is the higher-voltage 5V variant sharing the same pinout. When designing with this MCU, place a 100 nF decoupling capacitor as close as possible to each VDD/VSS pair, leave the exposed pad (EP) soldered to a contiguous copper pour tied to ground for thermal relief, and configure the Configuration Words for PPS lock and Code Protection before production. The internal 64 MHz HFINTOSC is factory-trimmed and typically eliminates the need for an external crystal, reducing BOM cost.

PIC18LF55K42T-I/MV

PIC18LF55K42T-I/MV - 8-Bit 64MHz 32KB Flash MCU | Microchip

The Microchip Technology PIC18LF55K42T-I/MV is an 8-bit PIC18 RISC microcontroller running up to 64 MHz with 32KB Flash and 2KB SRAM, housed in a 48-pin UQFN (6x6 mm) package with exposed pad. It belongs to the PIC18F-K42 family and integrates a 12-bit ADC2 (ADCC), 5-bit DAC, two comparators, configurable logic cells (CLC), vectored interrupts with DMA, and the peripheral pin select (PPS) system. What is a PIC18 microcontroller? A PIC18 is an 8-bit RISC microcontroller from Microchip's PIC family. Within the broader taxonomy, it sits as: PIC18 -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The "LF" prefix denotes the wide-voltage F-variant that operates from 1.8V to 3.6V, while the "K42" indicates the family's CIP (Core Independent Peripherals) feature set including DMA, CLC, and configurable logic. PIC18 microcontrollers dominate cost-sensitive 8-bit applications due to their deterministic instruction set, broad peripheral integration, and Microchip's free MPLAB X toolchain. Key features include 256 bytes of EEPROM, 44 user I/O lines, four 16-bit timers, two I2C/SPI/IART-configurable serial interfaces, and the XLP (eXtreme Low Power) family signature offering nanoWatt sleep currents below 100 nA. The UQFN-48 package with exposed pad delivers thermal resistance suitable for industrial -40C to +85C operation while saving PCB area versus QFP equivalents. Technically, the K42 architecture improves on prior PIC18F-K22/K40 devices by adding DMA-driven ADC scanning, vector interrupts with hardware priority, and on-chip 32-level stack. The Peripheral Pin Select (PPS) remaps most digital peripherals to almost any I/O pin, simplifying PCB routing in dense designs. Active mode current is approximately 4 mA at 64 MHz/3.3V, while deep sleep drops to nanoamp levels - the LF process node enables 1.8V minimum operation directly from a single-cell Li-ion battery. Typical applications include low-power IoT sensor nodes, battery-powered industrial sensors, home automation controllers, and compact user-interface modules driving segmented LCDs or keypads. The integrated 12-bit ADC and CIP peripherals make it well suited for mixed-signal front-ends where an external analog ASIC would otherwise be required. When designing with this MCU, allocate the PPS mapping early in the schematic phase to avoid pin-conflict rework. Decouple VDD with at least 100 nF plus 1 uF bulk capacitance placed within 5 mm of the exposed pad, and tie the EP to ground for thermal dissipation and noise immunity. Programming via ICSP requires the PGC/PGD pins to be reserved and not repurposed through PPS at runtime.
