PIC16LF18344-E/P - 8-Bit XLP MCU, 7KB Flash, 32MHz | Microchip

The Microchip Technology PIC16LF18344-E/P is an 8-bit PIC microcontroller from the PIC16F family featuring eXtreme Low Power (XLP) technology, 7KB (4K x 14 words) of Flash program memory, 512 bytes of SRAM, and 256 bytes of EEPROM. The device operates at up to 32 MHz internal clock, integrates a 20-pin PDIP (0.300 inch, 7.62 mm) package, and targets 1.8V to 3.6V low-voltage applications including battery-powered IoT nodes, sensor interfaces, and consumer devices. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on one die, allowing embedded products to replace discrete logic with programmable intelligence. Within the broader power-managed semiconductor taxonomy, an 8-bit PIC MCU sits below 16-bit dsPIC and 32-bit Cortex-M microcontrollers in processing capability, but it offers the lowest cost, lowest active and sleep current, and simplest toolchain for non-connectivity edge tasks. The PIC16F1xxx enhanced mid-range core adds Peripheral Pin Select (PPS), Core Independent Peripherals (CIPs), and the XLP nanoWatt sleep modes that define this generation. Key differentiating features of the PIC16LF18344 include 7KB self-programmable Flash, 256 bytes EEPROM, up to 17 I/O pins, an integrated 10-bit ADC with computation, two comparators with 5-bit DAC references, Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), Numerically Controlled Oscillator (NCO), and four 16-bit timers. The Peripheral Pin Select module lets the user remap most digital peripherals to almost any I/O pin, which simplifies PCB layout and frees the MCU from pin-strict peripheral allocation. The CWG and NCO together provide high-resolution PWM and arbitrary waveform synthesis without CPU intervention, supporting motor control, lighting, and power-conversion loops. The architecture combines a Harvard RISC core with a 14-bit instruction word, two-cycle hardware stack, and hardware multiplier. XLP technology delivers typical sleep currents of roughly 30 nA with the watchdog enabled and several hundred nA with the Real-Time Clock running, extending battery life in duty-cycled wireless sensor applications. The 32 MHz internal oscillator eliminates an external crystal on most designs, and the integrated temperature indicator and fixed-voltage reference simplify analog calibration. Typical applications for the PIC16LF18344-E/P include low-power IoT sensor endpoints, wearable health monitors, remote controls, low-end lighting controllers, small appliance user interfaces, and battery-backed metering products. The DIP-20 package specifically supports prototyping, hobby projects, through-hole manufacturing, education labs, and pre-production builds that benefit from socketed or hand-solderable parts. When designing with the PIC16LF18344-E/P, keep VDDCORE decoupling within 5 mm of the dedicated pin pair, place the 0.1 uF VDD bypass first in the layout, and route the ICSPDAT/ICSPCLK pair to a 5-pin in-circuit programming header for field updates. PPS reassignment should be locked in code before peripheral initialization to avoid glitching on remapped outputs. This page consolidates distributor pricing as of 2026-09-24, verified drop-in alternatives in the same 20-pin PDIP footprint, and practical design notes not found in the manufacturer datasheet, giving buyers and engineers a faster path from selection to production.

The device operates from 1.8V to 3.6V and combines Core Independent Peripherals (CIPs) with eXtreme Low Power (XLP) technology, supporting both analog and digital functions in a single core. An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), non-volatile data memory (EEPROM), and a set of peripherals onto a single die. The PIC16 family belongs to the PIC (Peripheral Interface Controller) architecture, a Harvard-design RISC core with separate program and data buses that has been produced since the 1970s. Within that hierarchy, the LF sub-family denotes low-voltage variants (1.8V-3.6V), and the 183xx series emphasizes mixed-signal integration with Peripheral Pin Select (PPS), Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), and multiple communications peripherals. Key features include an integrated 10-bit ADC with Computation (ADC2) providing automated averaging, threshold comparison, and oversampling, a 5-bit DAC, two 8-bit timers, one 16-bit timer, Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART), SPI, I2C, up to 17 I/O pins, and 256 bytes of EEPROM. The PPS module allows digital peripheral signals (CLC, CWG, CCP, PWM, communications) to be remapped to most I/O pins, dramatically easing PCB layout constraints. The architecture is built around an enhanced mid-range PIC16 CPU core with a hardware stack, hardware interrupt controller, and a single-cycle instruction fetch. The XLP design provides sleep currents in the nanoamp range, making the part suitable for battery-powered products that must wake periodically, sample a sensor, transmit, and return to sleep. Typical applications include IoT sensor nodes, low-power wireless remote controls, battery-powered medical wearables, consumer appliances with capacitive touch, industrial sensor transmitters, and small white-goods control boards. The wide peripheral mix also supports simple closed-loop control and LED driving via PWM, CWG, and the on-chip comparator and DAC. When designing with this device, plan the peripheral-to-pin map via PPS before laying out the PCB - remapping digital functions after layout forces a board respin. For lowest sleep current, disable unused peripherals via PMD, switch to the LFINTOSC during idle periods, and verify that pull-ups on MCLR are not leaking current.

The Microchip Technology PIC16LF18345-E/GZVAO is an 8-bit PIC microcontroller from the PIC16F family featuring 14KB of Flash program memory, 256 bytes of EEPROM, 1KB of RAM, and a 32MHz CPU core, housed in a 20-pin UQFN (4x4 mm) package with automotive AEC-Q100 qualification. This variant is the low-voltage 'LF' member of the PIC16(L)F18325/18345 family and runs from 1.8V to 3.6V supply rails with eXtreme Low Power (XLP) technology that enables nanoWatt sleep currents below 100 nA typical. An 8-bit microcontroller is a single-chip computer built around an 8-bit data-path CPU, on-chip Flash and RAM, and a curated set of analog and digital peripherals. The PIC16 family sits in Microchip's mid-range PIC portfolio, sitting hierarchically between PIC10/12/16 baseline parts and the PIC18/dsPIC33 high-performance parts. PIC16F devices use a RISC architecture with a fixed instruction set tuned for deterministic interrupt response and very low active current. Combined with integrated Core Independent Peripherals (CIPs), the PIC16LF18345 can handle signal generation, waveform timing, and inter-module glue logic without CPU intervention, leaving the core free for application code. Key features of this MCU include 12 or 18 selectable I/O pins, a 10-bit ADC with computation, 5-bit and 8-bit DACs, two 10-bit PWMs, Capture/Compare/PWM (CCP), Complementary Waveform Generator (CWG), Configurable Logic Cell (CLC), Numerically Controlled Oscillator (NCO), and Peripheral Pin Select (PPS) for flexible digital routing. The ICSP/ICD debug interface is supported through the standard 6-pin header. Operating temperature spans -40C to +125C (automotive 'E' grade). Architecturally, the device uses a Harvard-style 14-bit instruction word with a 2-stage pipeline, allowing most instructions to complete in one instruction cycle (4 system clock cycles). PPS remapping lets designers assign digital peripherals to almost any I/O pin after PCB layout, greatly simplifying routing in dense mixed-signal designs. Typical applications include automotive body electronics and sensor conditioning, ultra-low-power IoT sensor nodes, battery-powered wearables, LED lighting control with CWG-driven high-resolution dimming, and general-purpose motor control using CCP/PWM. The AEC-Q100 qualification also suits it for under-hood and cabin electronics. When designing with this device, select the LF variant (as here) for battery-powered or 3.3V systems. For 5V-only boards, choose the PIC16F18345 version. Keep the analog and digital supply traces short and decoupled with 100 nF + 1uF bulk caps placed within 5 mm of the VDD pins. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers select and qualify the right PIC16LF18345 variant for their application.

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.

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.

PIC16LF18346-E/GZ

PIC16LF18346-E/GZ - 8-bit XLP MCU 32MHz 28KB Flash 20-UQFN | Microchip

The Microchip Technology PIC16LF18346-E/GZ is an 8-bit PIC microcontroller from the PIC® XLP™ 16F family, featuring a 32 MHz CPU core, 28 KB (16K x 14) of Flash program memory, 2 KB SRAM and 256 B EEPROM, housed in a 20-pin UQFN (GZ) 4x4 mm package. The 'LF' prefix denotes the wide-voltage eXtreme Low Power (XLP) variant, supporting a VDD range of 1.8V to 3.6V with operation down to 1.8V at 16 MHz for battery-driven designs. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program storage (Flash), and configurable peripherals around an 8-bit data path. Within the broader electronics taxonomy, 8-bit MCUs sit below 16-bit and 32-bit microcontrollers in arithmetic throughput, but their deterministic instruction timing, low power consumption, low cost and small footprint keep them dominant in cost-sensitive, deeply embedded roles such as sensor front-ends, appliance controls and battery-powered IoT nodes. The PIC16F family specifically targets applications that need Core Independent Peripherals (CIPs) - such as CLC, CWG and PPS - so that simple tasks can run without waking the CPU. Key features include Peripheral Pin Select (PPS) for flexible digital peripheral pin mapping, a 10-bit ADC with computation, two SPI/I²C, Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), and XLP technology with sub-uA sleep currents. The 20-UQFN package gives a very small PCB footprint while still exposing the full set of peripherals. The device is rated for the extended -40 °C to +125 °C operating range and ships as an 'E' (engineering sample / extended temp) grade. Typical applications include low-power IoT sensor nodes, battery chargers, energy harvesting IC front-ends, small appliances, LED lighting controllers, and remote controls. The wide operating voltage combined with deep-sleep nanoWatt XLP modes enables multi-year coin-cell battery life in duty-cycled sensor products. When designing with this MCU, ensure that decoupling is placed within a few millimetres of VDD, that unused I/O pins are configured as outputs low (not floating), and that PPS assignments do not inadvertently route peripherals onto debug pins.

PIC16LF18346-E/P

PIC16LF18346-E/P - 8-Bit XLP MCU, 28KB Flash, 32MHz | Microchip

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
PIC16LF18346-E/SS

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.

PIC16LF18346-E/SSVAO

PIC16LF18346-E/SSVAO - 8-Bit XLP MCU, 28KB Flash, 20-SSOP | Microchip

The Microchip PIC16LF18346-E/SSVAO is an 8-bit PIC® XLP™ microcontroller featuring 28KB (16K x 14) Flash program memory, 2KB RAM, and a 32MHz internal oscillator, housed in a 20-pin SSOP package. It operates from 1.8V to 3.6V, supporting low-voltage battery-powered applications, and provides 18 I/O pins with Peripheral Pin Select (PPS) for flexible digital peripheral routing. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and peripherals such as ADCs, timers, and communication interfaces. The PIC16LF18346 belongs to Microchip's PIC16F/LF family of 8-bit RISC microcontrollers, which sit in the broader taxonomy of microcontrollers -> embedded microcontrollers -> semiconductor ICs. The 'LF' suffix denotes the low-voltage (1.8V-3.6V) variant optimized for eXtreme Low Power (XLP) operation, while the 'F' variant supports 2.3V-5.5V. XLP technology delivers nanoWatt sleep currents in the order of tens of nA, making this part ideal for energy-harvesting and battery-backed designs. Key features include Core Independent Peripherals (CIPs) such as the Configurable Logic Cell (CLC), Complementary Waveform Generator (CWG), Numerically Controlled Oscillator (NCO), and multiple Capture/Compare/PWM (CCP) modules. The 10-bit ADC with computation, 5-bit DAC, two comparators, and EUSART/I2C/SPI interfaces provide rich analog and digital connectivity. PPS allows digital peripheral pins to be remapped at runtime, simplifying PCB layout. Architecturally, the device uses an 8-bit RISC Harvard core with a 14-bit instruction word and 32MHz maximum clock, providing up to 8 MIPS throughput. The CIPs execute hardware state machines without CPU intervention, freeing the core for low-duty-cycle sleep modes where XLP nanoWatt technology drops quiescent current to single-digit microamps. Typical applications include IoT sensor nodes, wearable health monitors, remote controls, low-power wireless sensor interfaces, automotive body electronics (the /SSVAO suffix indicates AEC-Q100 automotive qualification), and consumer battery-powered devices. The wide 1.8V-3.6V supply range is ideal for single-cell Li-ion or 2x AA battery chemistries. When designing with this part, observe the following: the PPS feature must be configured in firmware before digital peripherals can function; the /SSVAO suffix denotes automotive grade and incurs additional cost; and decoupling requires a 0.1µF ceramic capacitor placed within 3mm of VDD. Use MPLAB X IDE with XC8 compiler for development.
