PIC16LF18345-E/P - 8-Bit 32MHz XLP MCU 14KB Flash 20-PDIP | Microchip

The Microchip Technology PIC16LF18345-E/P is an 8-bit PIC microcontroller from the PIC16F XLP family, featuring 14KB (8K x 14) of Flash program memory, 1KB of RAM, and 256 bytes of EEPROM in a 20-pin PDIP through-hole package. It operates from a wide 1.8V to 3.6V supply and supports a maximum CPU clock of 32MHz, achieving up to 8 MIPS throughput while consuming only nanoWatt sleep currents thanks to its eXtreme Low Power (XLP) technology. The MCU integrates a 10-bit ADC, 5-bit/8-bit DAC, comparators, PWM modules, and Core Independent Peripherals (CIPs) that offload tasks from the CPU. The -E suffix indicates an extended -40C to +125C operating temperature range suitable for industrial and harsh-environment deployments. A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, I/O peripherals, and often analog blocks such as ADC/DAC and comparators. In the broader taxonomy, the PIC16LF18345 belongs to the 8-bit PIC16 family within the PIC microcontroller hierarchy, sitting under Microchip's PIC line, which in turn falls under the broader category of embedded microcontrollers (sub-class of microprocessors). 8-bit MCUs like this one typically target cost-sensitive, low-power applications where deterministic real-time behavior and simple peripheral integration outweigh raw computational throughput. Key features include Peripheral Pin Select (PPS) for flexible pin-function remapping, an on-chip temperature indicator, multiple communication peripherals (EUSART, I2C, SPI), and hardware CLC, NCO, and PWM peripherals that operate independently of the CPU. The XLP technology includes IDLE/DOZE power-saving modes and ultra-low-power sleep currents down to ~30 nA typical with full RAM retention, allowing battery-powered designs to run for years on a single cell. The integrated 10-bit ADC supports up to 9 channels with hardware capacitive voltage division and is paired with a 5-bit/8-bit DAC for analog stimulus generation. Architecturally, the PIC16LF18345 uses a RISC-based enhanced mid-range core with a hardware multiplier, 49 instructions, and a single-cycle instruction decoder at 32MHz. The CIPs (CLC, NCO, PWM, COG, and CRC) let designers implement state machines, waveform generation, and communication glue logic in silicon without CPU intervention, reducing code size and improving deterministic latency. Internal oscillator options include a 32MHz HFINTOSC with PLL and a 31kHz LFINTOSC, eliminating external timing components in many designs. Typical applications include low-power IoT sensor nodes, battery-powered remote controls, consumer appliances, industrial sensor conditioning, automotive body and lighting controllers (sub-system level), and portable medical devices. The wide -40C to +125C operating range and XLP modes suit outdoor installations and energy-harvesting designs where quiescent current dominates battery life. When designing with this MCU, ensure VDDCORE decoupling (0.1uF + 1uF) is placed within a few millimeters of the supply pins, and that unused I/O are configured as outputs low rather than floating to minimize sleep-mode current. Use the PPS feature to route peripherals to convenient pins without redesigning the PCB layout. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a one-stop reference for selection, sourcing, and PCB layout decisions.

PIC16LF18345-E/SO - 8-Bit MCU, 14KB Flash, XLP, 20-SOIC | Microchip

The Microchip PIC16LF18345-E/SO is an 8-bit PIC16 microcontroller in the PIC16F/LF18325/18345 family, featuring 14KB Flash program memory, 1KB SRAM, 256B EEPROM, and a 32 MHz internal oscillator, housed in a 20-pin SOIC package. It is part of Microchip's eXtreme Low Power (XLP) family designed for general-purpose and low-power applications across industrial and consumer markets. What is a PIC16 8-bit microcontroller? PIC16 microcontrollers are Microchip's mid-range 8-bit MCU family based on the RISC PIC architecture. PIC16 → 8-bit microcontroller → microcontroller (MCU) → embedded processor → semiconductor IC. They integrate a CPU core, Flash program memory, SRAM, EEPROM, and a rich set of peripherals (ADC, timers, PWM, communication, etc.) into a single chip. The LF prefix denotes the low-voltage, low-power variant optimized for battery-powered applications, while the XLP technology extends battery life through nanoWatt sleep modes, low sleep current, and efficient peripheral gating. Key features include a 10-bit ADC with computation, a 5-bit DAC, comparators, 10-bit PWM with auto-shutdown, configurable logic cells (CLC), numerically controlled oscillator (NCO), complementary waveform generator (CWG), and peripheral pin select (PPS) for flexible I/O mapping. The device also integrates EUSART, SPI, and I2C communication peripherals, along with multiple capture/compare/PWM (CCP) modules for motor and lighting control. The PIC16LF18345 uses a Harvard RISC architecture with a 14-bit instruction word and 32 MHz internal oscillator, delivering up to 8 MIPS while consuming very low active current. PPS allows most digital peripherals to be routed to any I/O pin, simplifying PCB layout and BOM reuse across variants. The XLP technology provides deep-sleep currents as low as a few hundred nanoamperes with retention, making the part attractive for energy-harvesting and battery-backed designs. Typical applications include IoT sensor nodes, battery-powered remote controls, low-power wireless sensor endpoints, small home appliances, LED lighting controllers, sensor signal conditioning, and consumer electronics requiring analog peripherals and communication interfaces. The 20-SOIC package supports hand-soldering and wave-soldering on conventional FR-4 boards, making the part popular for prototypes and low-volume production. When designing with this device, leverage the PPS mapping to assign peripherals to convenient pins and use the nanoWatt XLP sleep modes to extend battery life. Always validate the analog pin assignments against the device's datasheet pinout table before layout, since PPS does not cover all functions and some pins have analog-only or digital-only roles.

PIC16LF18345-I/SO

PIC16LF18345-I/SO - 8-Bit 32MHz XLP MCU 14KB Flash | Microchip

The Microchip Technology PIC16LF18345-I/SO is an 8-bit PIC16F microcontroller combining Core Independent Peripherals, eXtreme Low Power (XLP) technology, and Peripheral Pin Select (PPS) flexibility in a 20-pin 300-mil SOIC package. Per the manufacturer datasheet, the device runs at up to 32 MHz, integrates 14 KB (8K x 14) of Flash program memory, 1 KB of SRAM, and 256 bytes of EEPROM, and supports a wide 1.8V to 3.6V operating voltage range for battery-powered designs. An 8-bit PIC microcontroller is a Harvard-architecture RISC device that executes one instruction per clock cycle with a deterministic instruction set, targeting low-power embedded control. PIC16F microcontrollers sit within Microchip's product hierarchy below the PIC18/dsPIC families and above the 8-bit baseline (PIC10/12/16) cores, occupying the lower-power edge of Microchip's mid-density MCU portfolio (low-power MCU -> 8-bit MCU -> microcontroller -> embedded IC -> semiconductor). Key features include 17 channels of 10-bit ADC, a 5-bit DAC, two comparators, two PWM modules, nine timers, and a watchdog timer. Communication peripherals include EUSART, I2C, and SPI. The CWG, CLC, NCO, and PPS Core Independent Peripherals allow hardware-driven logic and signal remapping without CPU intervention, reducing active time and total energy in event-driven systems. XLP technology delivers nanoWatt sleep currents with multiple Doze and Idle modes that suit energy-harvesting nodes. Internally the device uses a 32 MHz internal oscillator selectable against an external crystal, with Fail-Safe Clock Monitor, two-speed start-up, and a configurable instruction pipeline. This architecture supports deterministic interrupt response while the integrated peripherals offload reaction time from the CPU, an important consideration in low-power sensor and signal-conditioning subsystems. Typical applications include IoT sensor nodes, battery-powered wearables, home automation controllers, automotive body electronics (under-hood requires AEC-Q100 grade), industrial sensor signal conditioning, and Consumer IR/remote control units. For automotive-grade production, the PIC16F18345-I/SO and PIC16LF18345-I/SO Q1 (AEC-Q100 qualified) variants are recommended instead of the standard -I industrial-grade part. Design consideration: PPS allows digital peripheral pin remapping but does not move analog channels; reserve analog-capable pins (e.g., ANx on PORTA) for ADC inputs while routing EUSART/SPI/PWM via PPS to the remaining digital-capable pins to avoid layout rework.

The Microchip PIC16LF18346-E/P is an 8-bit PIC® XLP™ 16F microcontroller with 28KB (16K x 14 words) of Flash program memory, 2KB RAM, and 256B EEPROM, housed in a 20-pin PDIP through-hole package. It operates at up to 32 MHz from a 1.8V to 3.6V supply, integrating Core Independent Peripherals (CIPs), a 10-bit ADC with computation, configurable logic cells (CLC), complementary waveform generators (CWG), and Peripheral Pin Select (PPS) for flexible digital routing. A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (typically Flash), volatile data memory (RAM), and a configurable set of analog and digital peripherals. The PIC16LF18346 sits within Microchip's PIC16 mid-range MCU family, which occupies the entry-level to mid-tier segment of the 8-bit microcontroller market. The 'LF' prefix denotes the XLP (eXtreme Low Power) sub-family optimized for battery applications, while the 'PIC16' prefix indicates the 14-bit instruction word architecture shared across this family. Within the broader electronics taxonomy, this device belongs to: microcontroller -> 8-bit MCU -> embedded controller -> semiconductor IC. Key features include nanoWatt XLP technology with sleep currents as low as 60 nA (typical), 2x SPI/I2C, 2x UART, 2x CCP/PWM, 1x 10-bit ADC with automatic threshold scanning, 1x 5-bit DAC, 1x comparator, and up to 18 I/O pins via PPS mapping. The 20-pin PDIP package provides easy through-hole prototyping for hobbyists, educators, and low-volume production. Architecturally, the device uses a Harvard RISC core with a 14-bit instruction set and a hardware stack, executing most instructions in one cycle at 32 MHz (8 MIPS). PPS allows remapping of digital functions (CLC, CWG, CCP, PWM, communications) to nearly any I/O pin, simplifying PCB layout and reducing firmware redesign when port assignments change. Typical applications include battery-powered IoT sensor nodes, low-power wireless remotes, LED lighting controllers, environmental data loggers, consumer appliance controls, and small motor-driver front ends. The combination of PPS flexibility and CIPs enables designers to implement state machines, waveform synthesis, and sensor sampling without burdening the CPU. When designing with the PIC16LF18346-E/P, plan the power budget carefully: deep sleep draws nanoamps but active current is single-digit mA depending on peripherals enabled. Always include a 0.1µF decoupling capacitor within a few millimeters of VDD/VSS, and consider a 10µF bulk capacitor on the rail for ADC accuracy.

PIC16LF18346-E/SS - 8-bit XLP MCU, 32MHz, 28KB Flash | Microchip

The Microchip Technology PIC16LF18346-E/SS is an 8-bit PIC microcontroller from the PIC16F/LF183xx family with eXtreme Low Power (XLP) technology, 32 MHz operation, and 28 KB (16K x 14) of Flash program memory in a 20-pin SSOP package. Operating from 1.8 V to 3.6 V with 2 KB RAM, 256 B EEPROM, a 10-bit ADC, a 5-bit DAC, two comparators, 10-bit PWM, and Core Independent Peripherals (CLC, CWG, NCO, CCP), it packs high analog integration and rich peripheral logic into a 20-pin footprint. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals. An 8-bit MCU executes instructions on 8-bit wide data paths, which historically cost less per unit than 16-bit or 32-bit parts and remain economical for sensor interfacing, simple control loops, and user-interface tasks. The PIC16LF18346-E/SS sits in the Power Management > Battery-friendly tier of the PIC16 product hierarchy (PIC16 > 8-bit MCU > microcontroller > embedded computing > semiconductor). It is the "LF" (low-voltage, low-power) variant of the PIC16F18346, differing primarily in VDD range and active/quiescent current. Key features include an instruction-cycle speed of 32 MHz / 8 MIPS via the internal oscillator, 18 I/O pins with Peripheral Pin Select (PPS) for remappable digital peripherals, two EUSART modules, two SPI/I2C interfaces, on-chip debugging via ICD, and XLP nanoWatt sleep currents in the sub-microamp range. The integrated 10-bit ADC with computation (ADC2) performs automatic averaging, threshold detection, and burst-mode averaging, offloading work from the CPU. Hardware limit timers, CRC/SCAN, and zero-cross detection support functional-safety and capacitive-touch front ends. The architecture combines a RISC-style 14-bit instruction set with Harvard bus, giving deterministic single-cycle execution for most instructions and predictable interrupt latency. XLP technology uses dynamic workload scaling, deep sleep with peripheral wake-up, and a low-power WDT so battery-powered nodes can run for years from a single cell. PPS allows designers to route digital peripherals (CLC, PWM, EUSART, SPI, I2C) to any available I/O, simplifying PCB layout. Typical applications include IoT sensor nodes, low-power wireless sensor hubs, automotive body and lighting controllers, capacitive-touch user interfaces, small appliance controls, and consumer white goods. Designers choose it when they need an aggressive low-power 8-bit core with strong analog and lots of CIP logic in a small SSOP-20 footprint. When designing with this MCU, place a 100 nF decoupling capacitor adjacent to each VDD pin and use short traces to the ground paddle of the SSOP. Take advantage of PPS to clean up PCB routing, and use the ADC2 computation engine to reduce CPU wake events in battery-powered designs. Boundary-scan programming is supported but dedicated ICSP/ICD pins should remain accessible in the layout.

PIC16LF18346T-I/SS - 32MHz 8-bit XLP MCU, 28KB Flash | Microchip

The Microchip PIC16LF18346T-I/SS is an 8-bit PIC16 microcontroller from the PIC® XLP™ 16F family, integrating 28 KB (16K x 14) of Flash program memory, 2 KB of RAM, and 256 bytes of EEPROM into a 20-pin SSOP package rated for industrial -40°C to +85°C operation. It runs at up to 32 MHz from a 1.8 V to 3.6 V supply and is built on CMOS process technology with eXtreme Low Power (XLP) technology aimed at battery-powered designs. A 10-bit ADC with up to 12 input channels, a 5-bit DAC with 32 selectable levels, two Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART) modules and two SPI/I²C peripherals provide the analog and digital interfaces typically required by sensing, human-machine, and IoT products. An 8-bit microcontroller is a single-chip computer built around an 8-bit data path and Harvard-architecture CISC core, optimized for deterministic control of simple analog and digital I/O at very low cost and ultra-low power. Within the broader taxonomy these parts are classified as microcontrollers (MCU) -> 8-bit microcontrollers -> low-power microcontrollers -> PIC16 family -> PIC16F183xx sub-family. They sit below 16-bit MCUs and 32-bit Cortex-M cores in compute and memory scale, but excel at energy efficiency, real-time interrupt response, and short development cycles where raw MIPS-per-dollar matters more than absolute throughput. The LF18346's Core Independent Peripherals (CIPs) include the Configurable Logic Cell (CLC), Complementary Waveform Generator (CWG), Numerically Controlled Oscillator (NCO), and multiple Capture/Compare/PWM (CCP) modules that operate without CPU intervention. The Peripheral Pin Select (PPS) feature allows digital peripherals to be remapped to alternate I/O pins, which simplifies PCB layout in space-constrained SSOP designs. Instruction execution is enhanced by an internal 32 MHz oscillator that is factory calibrated to within ±1% across the full voltage and temperature range, eliminating the need for an external crystal in cost-sensitive applications. Typical applications include battery-powered sensor nodes, wearable health monitors, remote controls, low-power IoT edge devices, and capacitive-touch user interfaces. The 256-byte EEPROM is well suited for storing calibration constants, device IDs, and user preferences across power cycles, while the 2 KB RAM supports modest protocol stacks such as SMBus or Modbus slave on industrial sensors. Designers who upgrade from smaller PIC16 devices appreciate the migration path this part provides within the same MPLAB X IDE and XC8 toolchain. Designers should pair this device with a low-ESR ceramic decoupling capacitor of at least 100 nF placed within 2-3 mm of the VDD pin, and a bulk capacitor of 1-10 µF on the same rail. The unused I/O pins should be configured as outputs low or inputs with internal weak pull-ups enabled to minimize sleep current, and care must be taken to keep unused PPS-mapped peripherals in their reset state to avoid spurious wake events.

The 12-bit ADCC enables on-chip averaging, oversampling, and automated threshold comparisons, while the CWG and PWM peripherals simplify synchronous power-stage and lighting-control loops. Together these peripherals support digitally controlled analog loops without CPU intervention. Architecturally, the PIC16LF18424 combines the mid-range 16-bit instruction set extension with a peripheral-rich analog front-end, making it well suited to mixed-signal sensor nodes. Its internal oscillator, programmable reference and on-chip temperature indicator reduce external BOM while the 14-pin PDIP package remains breadboard-friendly for prototypes. Typical applications include battery-powered IoT sensor nodes, low-cost consumer remote controls, LED lighting control, simple motor/gate-drive timing, portable medical accessories, and industrial sensor interfaces. The wide 1.8V-3.6V supply window lets designers run directly from single-cell Li-coin or two alkaline cells. When designing with this device, place a 0.1 uF decoupling capacitor adjacent to VDD and provide a bulk cap on the MCLR pull-up network. Verify unused I/O configuration in firmware (digital vs analog) to avoid unintended current draw in XLP sleep modes.

PIC16LF18424-E/SL - 8-bit XLP MCU, 7KB Flash, 32MHz, SOIC-14
PIC16LF18424-E/SL

PIC16LF18424-E/SL - 8-bit XLP MCU, 7KB Flash, 32MHz, SOIC-14

The Microchip PIC16LF18424-E/SL is an 8-bit PIC microcontroller built on the eXtreme Low-Power (XLP) architecture, delivering 32 MHz of computational performance with 7 KB of Flash program memory (4K x 14 words), 512 bytes of SRAM, and 256 bytes of EEPROM. Housed in a 14-pin SOIC package, the device integrates Core Independent Peripherals (CIPs) including a 12-bit ADC with Computation (ADCC), two 10-bit PWMs, a Complementary Waveform Generator (CWG), a 5-bit DAC, two comparators, an EUSART, and SPI/I2C interfaces, enabling compact mixed-signal designs with minimal external components. An 8-bit microcontroller is a single-chip computer built around an 8-bit data path and is one of the most widely deployed categories of embedded controllers. Within the broader semiconductor taxonomy, an 8-bit MCU belongs to microcontrollers, which in turn fall under integrated circuits (ICs) used for digital control. The PIC16F family is Microchip's flagship 8-bit platform, and the LF-prefix variants (PIC16LFxxxx) are the low-voltage, low-power siblings designed for battery and energy-harvesting applications. The "F" in the part number denotes Flash program memory, and the LF prefix denotes the operating voltage family extended down to roughly 1.8V. Key features of the PIC16LF18424-E/SL include the 12-bit ADCC that offloads averaging, filtering, and threshold-comparison tasks from the CPU, the CWG for hardware-generated complementary drive signals (useful for synchronous rectifiers and triac-like outputs), and the on-chip 5-bit DAC for setpoint generation. Together these CIPs allow the CPU to remain in sleep for longer intervals, which is the foundation of the part's XLP energy budget. The device also provides multiple clock options including a 32 MHz internal oscillator, a 31 kHz low-power oscillator, and an external clock input for designers needing tight timing. The LF process technology node, combined with Microchip's eXtreme Low-Power design techniques, delivers typical sleep currents in the nanoampere range with full RAM retention, making the PIC16LF18424-E/SL competitive with MSP430 and low-end ARM Cortex-M0+ parts on energy-per-computation benchmarks. The 14-pin footprint allocates 12 general-purpose I/O pins (subject to peripheral multiplexing), which is sufficient for sensor hubs, user-interface panels, and simple IoT edge nodes. Typical applications include battery-powered IoT sensor nodes, low-power remote controls, smart-metering peripherals, white-goods user interfaces, and small appliances where the MCU must wake briefly, perform ADCC-based decision making, and return to a deep-sleep state. It is also deployed in automotive body and interior sub-modules thanks to the -E (extended) -40C to +125C temperature grade and the -Q automotive-qualified sibling (PIC16F18424-E/SLVAO). When designing with this device, reserve budget for the ICSP programming pins (PGC/PGD) and ensure MCLR is properly handled for in-circuit programming; the SOIC-14 mechanical package is straightforward to hand-prototype and rework, which is a key advantage over smaller QFN variants. The CIP-rich peripheral set means the CPU rarely needs to wake from sleep to service peripherals.
