PIC16LF18346-I/P

PIC16LF18346-I/P - 32MHz 8-bit XLP MCU 28KB Flash DIP-20

The Microchip Technology PIC16LF18346-I/P is a 32 MHz 8-bit PIC® XLP™ 16F microcontroller with 28 KB Flash, 2 KB SRAM, and 256 B EEPROM in a 20-pin PDIP through-hole package. It operates from 1.8 V to 3.6 V with eXtreme Low Power (XLP) features, including nanoWatt sleep and active current draw down to the microampere range for battery-friendly designs. An 8-bit microcontroller is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and peripherals on one die. Within the broader taxonomy, the PIC16LF18346 sits in the 8-bit MCU family (microcontroller -> MCU -> 8-bit MCU -> PIC16 family -> PIC16F18xxx sub-family -> power management sub-system of an embedded design). The XLP designation specifically emphasizes ultra-low-power operation, extending battery life in portable, IoT, and energy-harvesting products compared with conventional 8-bit parts. Key features include Peripheral Pin Select (PPS) for flexible digital peripheral mapping, two Configurable Logic Cells (CLC) for hardware glue logic, a Numerical Controlled Oscillator (NCO) for fine-frequency synthesis, a 10-bit ADC with Computation, a 5-bit DAC, two CCP modules, Complementary Waveform Generation (CWG), and four 10-bit PWM channels. Two I²C and two UART/SPI interfaces support modern serial connectivity, and 256 B of EEPROM provides non-volatile data storage without external memory. The architecture uses a RISC-based 8-bit core with a 14-bit instruction word, hardware stack, and zero-latency interrupt handling. PPS routes digital peripherals to almost any I/O pin, letting designers swap pin assignments on the fly without respinning the PCB. Core Independent Peripherals (CIPs) such as CLC, CWG, NCO, and PWM operate without CPU intervention, allowing the core to remain in deep sleep and reducing average current to single-digit µA. Typical applications include battery-powered IoT sensor nodes, low-power remote controls, energy-harvesting devices, LED lighting controllers, and consumer appliances that demand long battery life and small footprints. The 20-pin PDIP package simplifies prototyping on breadboards and through-hole PCBs, making the device a common choice for evaluation, hobby, and low-volume industrial designs. When designing with this MCU, allocate decoupling capacitors (100 nF plus 1-10 µF bulk) close to VDD/AVDD pairs and respect the 3.6 V absolute maximum to avoid latch-up. Use PPS to remap peripherals before locking the I/O assignment, and verify unused peripherals are disabled in firmware to minimize quiescent draw.

It is supplied on tape-and-reel with the automotive-grade /GZVAO suffix and offers -40C to +125C extended operating temperature. An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates an 8-bit CPU core, program memory (Flash), data RAM, EEPROM, and a rich set of peripherals into a single IC. PIC microcontrollers are built on a modified Harvard RISC architecture: the program bus is separated from the data bus so the CPU can prefetch instructions while simultaneously reading or writing data. PIC16F-family MCUs sit in the middle of the Microchip 8-bit portfolio (PIC10/12/16/18), above PIC10/12 in capability and below PIC18 in code density, and the XLP variant is purpose-tuned for battery-powered IoT and portable products where quiescent current dominates energy budgets.

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.

A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory, data memory, and configurable peripherals on a single silicon die. PIC16F MCUs use a Harvard-architecture RISC core optimized for deterministic real-time control, and the 184xx family extends this with Core Independent Peripherals (CIPs) that operate autonomously without CPU intervention. The PIC16LF18425T-I/JQ belongs to the broader hierarchy: microcontroller -> 8-bit MCU -> PIC16F family -> XLP low-power subfamily, and is manufactured using CMOS process technology. Key differentiating features of the PIC16LF18425T-I/JQ include its 12-bit ADCC with automated averaging, oversampling, and threshold comparison, reducing firmware complexity for sensor monitoring. The CWG module generates complementary dead-band-controlled waveforms typically required for half-bridge power stages. The CLC allows combinatorial logic between peripherals to be wired in hardware, enabling custom glue logic without code overhead. Combined with 32MHz operation and 14KB of code space, these CIPs deliver high analog integration density for sensor and motor-control applications in a tiny 16-UQFN footprint. Architecturally, the PIC16LF18425T-I/JQ is built around the enhanced mid-range PIC16 core with a 14-bit instruction word, allowing each Flash location to store a single instruction and giving the part its 8K x 14 Flash organization. The 32MHz internal oscillator (with PLL) yields a 125ns instruction cycle, supporting precise timing in motor-control loops. XLP technology integrates nanoWatt XLP sleep modes, allowing the device to wake on peripheral triggers while drawing under 1 uA, ideal for energy-harvesting or coin-cell applications. Multiple I/O (12 of 16 pins) and high-current sink/source capability simplify driving LEDs, keypads, and power transistors directly. Typical applications include IoT sensor nodes, low-power wireless edge devices, battery-powered handheld instruments, LED lighting control, and small BLDC motor control. The combination of XLP sleep modes and 12-bit ADCC makes this MCU especially attractive for periodic-sampling sensor products where multi-year battery life is a primary design goal. When designing with this device, ensure your Vdd decoupling follows the manufacturer recommendations (typically 0.1 uF and 10 uF in parallel) and that unused I/O are configured as outputs low or inputs with internal pull-ups to minimize sleep current. ICSP programming pads should remain accessible for in-circuit firmware updates. Selecting the 'LF' variant limits Vdd to 3.6V, so if a 5V system rail is present, choose the standard 'F' variant instead. This page consolidates distributor pricing, same-package drop-in alternatives, application-specific design notes, and AI-search-optimized comparison tables that go beyond the manufacturer datasheet to help engineers select and source the right MCU.

PIC16LF18425T-I/SL - 14KB Flash XLP MCU | Microchip | SOIC-14

The Microchip Technology PIC16LF18425T-I/SL is an 8-bit PIC16 microcontroller from the PIC16F18425 family, featuring 14KB of Flash program memory (8K x 14 words), 1KB of RAM, and a 32MHz internal oscillator, packaged in a 14-pin SOIC (SL) package. The 'LF' prefix indicates an extended eXtreme Low-Power (XLP) variant operating from 1.8V to 3.6V, while the 'T' suffix denotes Tape & Reel packaging and 'I' indicates the industrial -40C to +85C temperature range. An 8-bit microcontroller (MCU) is a compact computing core that integrates a CPU, non-volatile program memory, working RAM, and a rich set of peripherals onto a single chip. PIC MCUs use a Harvard RISC architecture, where program and data buses are separated, allowing simultaneous instruction fetch and operand access in a single clock cycle. Within the broader semiconductor taxonomy, an MCU is a sub-class of microcontroller IC, itself a member of the integrated circuit family, designed for embedded control tasks rather than general computing. Key features of this device include two PWM modules, comparators, a Digital-to-Analog Converter (DAC), a 12-bit Analog-to-Digital Converter with Computation (ADCC), a Complementary Waveform Generator (CWG), an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), and SPI/I2C interfaces. These Core Independent Peripherals (CIPs) handle tasks autonomously from the CPU, freeing it for application logic and reducing firmware complexity. The 12-bit ADCC provides automated averaging, threshold detection, and hardware accumulation, enabling energy-efficient sensor acquisition. The PIC16LF18425T-I/SL also benefits from Microchip's eXtreme Low-Power (XLP) technology, supporting sleep currents down to the nanoampere range and active-mode efficiencies suitable for battery-powered sensor nodes. The 32MHz maximum CPU speed delivers up to 8 MIPS of throughput. The 14-pin SOIC package provides a robust, hand-solderable footprint with a 1.27mm pitch and standard 3.90mm body width, suitable for prototyping as well as volume manufacturing. Typical applications include IoT sensor nodes, battery-powered remote controls, low-power wireless sensor interfaces, LED lighting controls with dimming feedback, small motor control loops via the CWG, and consumer appliance user-interface panels. The combination of compact 14-pin packaging, low operating voltage, and rich analog peripherals makes it well-suited for space-constrained, energy-conscious designs. When designing with this part, ensure the supply voltage stays within the 1.8V to 3.6V LF range, since the non-LF PIC16F18425 variant is rated for 2.3V to 5.5V operation. Decouple VDD with a 100nF ceramic capacitor placed within 3mm of the pin, and reserve the ICSP pins (ICSPCLK/ICSPDAT) for in-circuit programming during development.

PIC16LF18425T-I/ST

PIC16LF18425T-I/ST - 8-Bit 32MHz MCU 14KB Flash | Microchip

The Microchip Technology PIC16LF18425T-I/ST is an 8-bit RISC microcontroller from the PIC16 (L)F184xx family featuring eXtreme Low-Power (XLP) technology and a 32 MHz internal oscillator, packaged in a 14-pin TSSOP. It integrates 14KB of Flash program memory, 1KB of SRAM, 256 bytes of EEPROM, and a rich set of Core Independent Peripherals (CIPs) including 12-bit ADCC, 5-bit DAC, two comparators, two PWM modules, a Complementary Waveform Generator (CWG), and configurable logic cells. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path. It is one of the most widely deployed computing architectures in the world because of its deterministic instruction cycle, low cost, low power consumption, and ease of programming. Within the broader semiconductor hierarchy, an 8-bit MCU is a sub-category of microcontroller -> embedded processor -> integrated circuit. The PIC16 core belongs to the Reduced Instruction Set Computer (RISC) family and executes most instructions in one instruction cycle, giving it deterministic throughput that is highly valued in real-time control loops. Key features include operation from 1.8V to 3.6V, an operating temperature range of -40C to +85C (industrial grade, indicated by the "I" in the part number), 11 timers, a 12-bit Analog-to-Digital Converter with Computation (ADCC) supporting automatic averaging, filtering and threshold comparison, and communication peripherals including EUSART, SPI, and I2C. The XLP nanoWatt technology enables sleep currents in the nanoamp range, which is critical for battery-powered applications such as IoT sensors and wearables. Architecturally, the device combines a Harvard-bus PIC16 CPU core with on-chip debug support, a wide array of Core Independent Peripherals (CIPs) that offload tasks from the CPU, and the Peripheral Pin Select (PPS) feature that allows digital peripheral I/O to be remapped to a wide choice of pins. This combination gives designers a flexible platform for mixed-signal embedded designs. Typical applications include low-power IoT sensor nodes, battery-powered wearables, consumer appliances, LED lighting controllers, automotive body and sensor nodes, and small industrial control boards. The 14-pin TSSOP footprint with PPS makes it suitable for compact designs where pin flexibility is essential. When designing with this device, ensure the power supply rail stays within the 1.8V to 3.6V window and provide proper decoupling close to the VDD/VSS pins. Note that the "LF" prefix indicates the low-voltage (1.8V-3.6V) variant - if a 5V supply rail is required, select the PIC16F18425 (non-LF) version instead, which shares the same 14-pin TSSOP pinout. The trailing "T" denotes tape-and-reel packaging for high-volume assembly. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet alone, so engineers can quickly evaluate the PIC16LF18425T-I/ST against drop-in substitutes for sourcing risk mitigation.

PIC16LF18426-E/JQ - 8-Bit XLP MCU 32MHz 28KB Flash | Microchip
PIC16LF18426-E/JQ

PIC16LF18426-E/JQ - 8-Bit XLP MCU 32MHz 28KB Flash | Microchip

The Microchip Technology PIC16LF18426-E/JQ is an 8-bit PIC microcontroller built on the enhanced mid-range core, delivering 32 MHz CPU performance from 28 KB (16K x 14) of Flash program memory, 2 KB of SRAM, and 256 bytes of EEPROM, all housed in a compact 16-pin UQFN-EP 4x4 mm package. It integrates Core Independent Peripherals (CIPs) such as a 12-bit ADC with Computation (ADCC), a 5-bit/8-bit DAC, two comparators, two 10-bit PWMs, Complementary Waveform Generator (CWG), Zero-Cross Detect (ZCD), and EUSART/SPI/I2C interfaces, providing high functional density for sensor and IoT nodes. An 8-bit microcontroller is a single-chip computer built around an 8-bit data path, optimized for deterministic real-time control, low power, and cost-sensitive embedded designs. Within the broader taxonomy, PIC16LF18426 sits under PIC microcontroller -> 8-bit MCU -> microcontroller unit -> integrated circuit -> semiconductor. The "LF" prefix denotes the eXtreme Low-Power (XLP) process variant, supporting operation from 1.8 V to 3.6 V with nanoWatt sleep currents in the order of tens of nanoamps, while the non-LF "F" variant extends to 5.5 V. Key features of the PIC16LF18426-E/JQ include active current consumption below 1 mA at 32 MHz with 3.3 V VDD, deep sleep currents below 100 nA with peripheral retention via the Windowed Watchdog Timer (WWDT), and 4 KB of self-programmable Flash. The device offers up to 17 I/O pins, internal 32 kHz and 32 MHz oscillators, and a temperature-indicator module that simplifies thermal monitoring. AEC-Q100 qualification is available on selected part numbers for automotive-grade designs. The PIC16LF18426 family uses a 14-bit instruction word RISC architecture with a single-cycle hardware multiplier, allowing many CIP operations to run independently of the CPU. This produces deterministic latency for sensor front-ends while keeping CPU wake time short - a critical balance for battery-powered edge devices. Typical applications include battery-powered IoT sensor nodes, low-power remote controls, wearable health and fitness devices, white-goods and appliance controllers, automotive body and lighting ECUs (AEC-Q100 parts), and industrial sensor transmitters. The combination of ADCC, ZCD, CWG, and PWMs enables single-chip control loops previously requiring dedicated analog ASICs. Design consideration: when migrating from a 5V PIC16F18426 to the 3.3V PIC16LF18426, verify that all peripherals operate at the lower rail - the LF device is not 5V tolerant on I/O. A simple BOM change to a 3.3V LDO is usually sufficient. Always place a 100 nF decoupling capacitor within 3 mm of VDD and a 10 uF bulk capacitor near the package. This page synthesizes distributor pricing, parametric drop-in alternatives, and practical design notes that complement the Microchip datasheet, helping engineers select, source, and apply the PIC16LF18426-E/JQ efficiently.
