The Microchip Technology PIC16LF1787-I/PT is an 8-bit PIC microcontroller built on the eXtreme Low Power (XLP) architecture, featuring 14KB (8K x 14 words) of Flash program memory, 1KB of ROM, and a maximum CPU clock of 32 MHz, housed in a 44-pin TQFP (PT) package with 10x10 mm body size. The LF prefix designates the wide-voltage 1.8V-3.6V core, ideal for battery-powered designs where quiescent current directly affects operating life. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, Flash program memory, peripherals, and I/O into one device. Within the broader taxonomy, MCUs belong to microcontrollers -> embedded processors -> digital ICs -> semiconductors. The PIC16F178x family sits in Microchip's mid-range PIC16 line, balancing analog integration, peripheral count, and ultra-low power operation for connected sensor and IoT edge nodes. Key features include 14KB self-programmable Flash with device ID protection, an integrated 12-bit ADC, on-chip op-amp and DAC peripherals, multiple PWM modules, I2C/SPI/UART communication interfaces, and XLP sleep currents in the nanoamp range. The 32 MHz internal oscillator eliminates external crystals for many designs, reducing BOM cost and PCB area. The 44-TQFP (PT) package provides 36 general-purpose I/O pins across seven I/O ports. The device uses a 14-bit modified Harvard RISC architecture with 49 single-word instructions, achieving 125 ns minimum instruction cycle at 32 MHz. Core-independent peripherals such as the Complementary Waveform Generator and Numerically Controlled Oscillator offload timing-critical tasks from the CPU, lowering average power in duty-cycled sensor applications. Typical applications include portable medical monitoring, IoT sensor nodes, battery-powered instrumentation, LED lighting controllers, and consumer appliances. The combination of 14KB Flash, 1KB RAM, and rich analog peripherals makes it well-suited for closed-loop control and signal conditioning tasks. When designing with this MCU, ensure decoupling capacitors are placed within 5 mm of VDD pins and that the ICSP programming pins (PGx, PGM) remain accessible for in-circuit programming. The LF voltage range requires level translation if interfacing to 5V peripherals.

PIC16LF1787T-I/MV - 8-bit MCU 32MHz 14KB Flash | Microchip

The Microchip Technology PIC16LF1787T-I/MV is an 8-bit PIC16LF178x family microcontroller running at 32 MHz with 14 KB of Flash program memory, packaged in a 40-pin UQFN-EP (5x5 mm) with exposed thermal pad. It belongs to the nanoWatt XLP ultra-low-power family (the "LF" prefix denotes the wide-Vdd, low-power variant) and integrates high-performance analog peripherals including a 12-bit ADC, 8-bit DAC, operational amplifiers, and three Programmable Switch Mode Controller (PSMC) modules. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path that integrates CPU, Flash, RAM, EEPROM, and peripherals. The PIC16 family occupies the mid-range PIC segment, sitting above baseline (PIC10/PIC12/PIC16F5x) and below the PIC18/dsPIC families. MCU -> PIC16 family -> PIC16LF178x sub-family -> PIC16LF1787 specific device, with the "LF" suffix and "nWLP/XLP" branding indicating Microchip's nanoWatt eXtreme Low Power technology for sleep currents in the sub-uA range. Key features include 8 K x 14 Flash (14 KB), 1 KB RAM, 256 B EEPROM, the afore-mentioned 12-bit ADC and 8-bit DAC, OPAmp modules, three PSMC channels providing flexible PWM with programmable frequency, duty cycle, and dead-band control, plus standard peripherals (CCP, EUSART, I2C, SPI, comparators). Connectivity is I2C/SPI/UART on 35 I/O pins. Supply voltage spans 1.8 V to 3.6 V (LF "low-voltage/frequency" part). Designers should note the UQFN-EP exposed pad must be soldered to the PCB ground plane for thermal dissipation; operating temperature range is -40 °C to +85 °C (industrial, "I" suffix). The PSMC peripheral differentiates this MCU from standard CCP timers by allowing digital feedback control of PWM frequency and pulse begin/end times. When migrating firmware, the PSMC registers and trigger sources differ from dsPIC PWM modules - check the Note: datasheet for register maps and the "Migrating from PIC16F1787" application note (refer to manufacturer documentation). Typical applications include LED lighting drivers (using PSMC for high-resolution dimming), Switch-mode power supply controllers, motor control (brushed DC up to 1.5 A drive via the integrated OPAmp + PSMC), battery-powered IoT sensor nodes (nWLP/XLP sleep modes), and small appliance control panels. The wide Vdd range and integrated analog make it a strong fit for mixed-signal designs that need to minimize external components. When designing with this device, the LF variant requires the 32 MHz internal oscillator to be used carefully - check the factory calibration value in the OSCTUNE register for temperature compensation. Total I/O count is 35 across a 40-pin package; the remaining pins are dedicated to Vdd/Vss and the EP. Plan pin allocation early, especially when assigning analog functions (AN0-ANxx) and the dedicated OPAmp input pins.

The integrated Core Independent Peripherals (CIPs) — CLC, NCO, DSM, and configurable op-amp — offload tasks from the CPU, enabling deterministic real-time response with minimal firmware overhead. Typical applications include LCD-driving embedded systems, sensor conditioning and data acquisition, low-speed motor control, and portable instrumentation. Industrial, consumer white goods, and battery-powered IoT endpoints are the most common end markets. When designing in the PIC16LF1787, plan for a 32-MHz maximum FOSC from the internal HFINTOSC at 3.3 V, ensure the BOR / watchdog configuration matches your fault-recovery policy, and verify that the TQFP-44 land pattern and pin-out match the selected variant (PT, ML, MV, SP) before PCB layout.

What is a PIC16 microcontroller? PIC16 (Peripheral Interface Controller, 8-bit family) is one of Microchip's foundational 8-bit MCU families, sitting between the 16-bit PIC24 and the resource-constrained PIC10/12 lines. The "LF" prefix denotes a wide-voltage (1.8 V to 3.6 V) variant for battery-powered applications, and the "XLP" branding marks parts that draw nano-amp-level sleep currents. PIC16 MCUs combine a Harvard RISC architecture, deterministic instruction pipeline, and rich on-chip analog peripherals, making them ideal for sensor-conditioning, motor-control, and human-interface applications where predictable behavior and minimal BOM cost matter more than raw CPU throughput. Key features of the PIC16LF1788 include active current typically in the microamp range, multiple low-power sleep modes drawing only nanoamps, an internal 32 MHz oscillator accurate to within roughly one percent across voltage and temperature, a wide operating voltage range of 1.8 V to 3.6 V, and an extended industrial temperature range of -40 deg C to +85 deg C. The 28-pin SOIC package is widely supported by hobbyist toolchains and breadboard-friendly breakout boards. Architecturally, the device uses an 8-bit data path with a 14-bit program word, giving roughly 8K usable single-word instructions per kilobyte of Flash, and the enhanced mid-range core adds hardware multiply and context-saving interrupts for responsive event handling. Integrated op-amps and comparators allow direct sensor-signal conditioning without external analog ICs, while the PSMC peripheral supports synchronizable switching converters and LED driving at high efficiency. Typical applications include battery-powered sensor nodes, IoT edge controllers, portable medical instrumentation, low-power motor control, LED lighting drivers, and consumer human-interface devices where long battery life and integrated analog simplify the BOM. The wide 28-SOIC footprint also suits hand-soldered prototyping. When designing with the PIC16LF1788, plan around the 1.8 V to 3.6 V supply: brown-out detection and the standard BOR/POR/Sleep resets are mandatory after every power rail event to guarantee defined startup. The internal 32 MHz oscillator eliminates an external crystal on most designs, but USB, CAN, or RF tasks still require the higher-precision PLLs or external references available on related PIC18/dsPIC devices. Use Microchip's MPLAB X IDE with the XC8 compiler and PICkit or ICD programmers for development.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (RAM), small data EEPROM, and a rich set of on-chip peripherals (ADC, DAC, timers, communication interfaces) onto one die. Within the broader embedded taxonomy, PIC16LF1789 belongs to: microcontroller -> 8-bit MCU -> PIC16 family -> PIC16F178x sub-family -> power management class with XLP technology. The XLP designation makes the LF line especially suited to battery-powered designs where deep-sleep currents measured in nanoamps are required. Key differentiating features include a 12-bit ADC with up to 32 single-ended channels, dual 5-bit and 8-bit DACs, on-chip operational amplifiers (Op Amps), a Peripheral Signal Modulator/Conditioner (PSMC) for advanced power-control timing, Fast Comparators, Capture/Compare/PWM (CCP), I2C/SPI, and an enhanced USART (EUSART). The integrated op amps allow closed-loop analog signal conditioning without external amplifiers, which simplifies BOM and shrinks PCB area for sensor-interface designs. Typical applications include industrial sensor signal conditioning, battery-powered IoT edge nodes, automotive body and HVAC control modules, precision metering and instrumentation, LED lighting with closed-loop current control using PSMC, and low-cost analog front ends where the on-chip DACs and op amps replace discrete analog stages. When laying out the PCB, route the analog AVCC/AGND pins directly to a star-grounded analog plane and keep digital switching traces away from the sensitive analog pins to preserve the 12-bit ADC SNR.

PIC16LF1789-I/PT

PIC16LF1789-I/PT - 8-Bit 32MHz 28KB Flash MCU | Microchip | TQFP-44

The Microchip Technology PIC16LF1789-I/PT is an 8-bit PIC microcontroller from the PIC16 (L)F1789 family running up to 32 MHz with 28 KB Flash, 2 KB RAM and 256 B EEPROM, housed in a 44-pin TQFP (10x10 mm) package. The "LF" prefix denotes the wide-voltage 1.8V-3.6V low-power variant with Microchip's eXtreme Low Power (XLP) technology, and the "I" suffix indicates the industrial -40C to +85C temperature grade. The device integrates a rich analog front-end including a 12-bit ADC, a 5-bit DAC, multiple op amps, comparators and an 8-bit DAC, while the digital core combines a 32 MHz internal oscillator, hardware PWM, communication peripherals (I2C, SPI, EUSART) and a 32-level hardware stack for the PIC RISC architecture. Compared to the non-LF PIC16F1789-I/PT, the LF version consumes roughly half the active current and offers much deeper sleep currents, making it suitable for battery-powered designs that still demand full analog performance. An 8-bit PIC microcontroller is a Harvard-architecture RISC processor optimized for low power, deterministic interrupt response and ease of peripheral integration. In the broader taxonomy, PIC16 sits between PIC10/12/14 entry-level MCUs and PIC18 mid-range MCUs. PIC microcontrollers belong to the larger family of microcontrollers (MCUs), which are a subset of microprocessors and embedded processors. PIC MCUs dominate cost-sensitive, low-power and motor/sensor-control applications because the integrated peripherals and tiny instruction set minimize external component count and firmware complexity. Key differentiating specifications of the PIC16LF1789 include: 28 KB self-programmable Flash program memory with 16K x 14 word organization, 2 KB SRAM, 256 B EEPROM for non-volatile data, up to 36 digital I/O pins, an integrated 12-bit ADC with up to 28 channels, three rail-to-rail op amps, two 5-bit DACs and one 8-bit DAC, plus three comparators and Capture/Compare/PWM modules. The XLP Sleep mode delivers nanoWatt-class standby current for always-on sensor nodes. The device is programmed and debugged through Microchip's MPLAB X IDE using the MPLAB ICD, PICKit or REAL ICE tools, with C18, XC8 and assembly language support. The PIC16LF1789 uses a modified Harvard architecture with separate program Flash and data EEPROM/SRAM buses, a 14-bit instruction word, and an instruction set optimized for one-cycle execution. Hardware multiplier support, interrupt shadow registers and a 32-level deep hardware stack simplify C-language firmware porting from PIC18 while retaining the deterministic timing that PIC users expect. A wide operating voltage window of 1.8V to 3.6V lets the same board design accept 2xAA batteries, single Li-Ion cells or 3.3V regulated rails, simplifying SKU consolidation. Typical applications for the PIC16LF1789-I/PT include low-power IoT sensor nodes with on-chip signal conditioning, portable medical monitoring devices such as pulse oximeters and glucose meters, LED lighting and color-mixing controllers that leverage the integrated DACs and PWM, battery-powered home automation and smart-home end nodes, automotive body and accessory subsystems (non-AEC-Q100 grade), industrial sensor signal conditioning, and small brushed DC or stepper motor control loops where the on-chip op amps and PWM reduce BOM cost. When designing with the PIC16LF1789-I/PT, observe the supply decoupling guidance: place a 100 nF ceramic capacitor directly across VDD/VSS pins and add a bulk 1-10 uF tantalum or ceramic capacitor near the MCU. The wide analog subsystem draws fast transient current during ADC conversions, so separating AVDD/AVSS filtering from VDD/VSS and using a ferrite bead on the digital rail improves ADC noise floor. Confirm that your firmware does not exceed 28 KB Flash (16K words) and respect the 4-word interrupt vector boundary.

The Microchip Technology PIC16LF1823-I/JQ is an 8-bit PIC16-family microcontroller based on the enhanced mid-range core, delivering 32 MIPS at 32 MHz from a 16-pin UQFN (4x4 mm) package with exposed pad. It integrates 3.5 KB (2K x 14) of self-programmable Flash program memory, 128 bytes of SRAM, and 256 bytes of EEPROM, plus 12 general-purpose I/O pins configurable for peripheral functions. The LF prefix indicates the wide-voltage, low-power 'F' variant rated 1.8V to 3.6V with Microchip's eXtreme Low Power (XLP) technology. An 8-bit PIC microcontroller is a RISC processor built around a Harvard architecture with separate program and data buses, executing one instruction per cycle (200 ns at 20 MHz, 125 ns at 32 MHz). The PIC16 enhanced mid-range core added a deeper call stack, hardware multiply, linear data memory, and C-friendly addressing compared with baseline PIC12/PIC16, while retaining the deterministic single-cycle execution that makes PIC MCUs popular in safety- and timing-sensitive embedded designs. This places the PIC16LF1823 within the broader hierarchy: PIC16 -> PIC microcontroller -> 8-bit MCU -> embedded microcontroller -> semiconductor IC. Key features include an integrated 32 MHz internal oscillator with ±1% accuracy after calibration, two 8-bit timers plus one 16-bit timer, a Master Synchronous Serial Port (MSSP) configurable as SPI or I2C (including I2C slave with address masking), an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) with auto-baud detect, a 10-bit Analog-to-Digital Converter (ADC) with up to 8 channels and computation features, two rail-to-rail rail-to-rail comparators with selectable references, a 5-bit DAC, a 10-bit PWM module, and on-board capacitive touch (mTouch) peripherals for buttons and sliders. Architecturally the device uses a modified Harvard layout with a 14-bit instruction word and 8-bit data path, plus nanoWatt XLP power management that drops the supply current to roughly 30 nA in sleep with Watchdog Timer disabled and active-low interrupt-driven wake from sleep on RB port-change. The 16-UQFN package exposes the die pad for thermal dissipation, which is essential when the part operates near the 3.6V maximum at 32 MHz full clock because the package is the dominant thermal path.

Typical applications include low-power IoT sensor nodes, battery-powered remote controls, LED lighting controllers, wearable health and fitness accessories, capacitive-touch user interfaces, and compact consumer appliances. The combination of XLP sleep current and a 10-bit ADC makes the device attractive for periodic-sampling sensor readout where total energy per measurement dominates the design budget. Designers should pay attention to three trade-offs. First, the 16-UQFN footprint is small (4x4 mm) but not breadboard-friendly - a breakout or hot-air rework is required for prototype soldering. Second, the device operates only to 3.6V, so any 5V logic level on an I/O pin requires a level translator. Third, the MSSP peripheral supports both SPI and I2C but only one mode can be active at a time; firmware must reconfigure the registers when switching protocols. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet itself.

PIC16LF1823-I/P

PIC16LF1823-I/P - 8-bit 32MHz XLP MCU 3.5KB Flash | Microchip

The Microchip Technology PIC16LF1823-I/P is an 8-bit PIC microcontroller built on the enhanced mid-range PIC16 core with nanoWatt XLP (eXtreme Low Power) technology. It operates at up to 32 MHz instruction-clock speed with 200 ns instruction cycle, integrates 3.5 KB (2K x 14) of self-programmable Flash program memory, 128 bytes of SRAM, and 256 bytes of EEPROM data memory, and is housed in a 14-pin PDIP through-hole package with 12 I/O pins. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, non-volatile storage, and programmable peripherals. The PIC16LF1823 belongs to the Microchip 8-bit PIC16 family, which sits inside the broader PIC product line, the 8-bit MCU category, and ultimately the embedded controller hierarchy. The 'LF' prefix denotes the wide-voltage 1.8V-3.6V variant designed for ultra-low-power XLP applications. Key features include an internal 32 MHz oscillator (factory calibrated to within +/-1 percent), an integrated 16-level hardware comparator, multiple 10-bit PWM modules, a Master Synchronous Serial Port (MSSP) supporting SPI and I2C (both Master and Slave), an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) with auto-baud detect, a 10-bit Analog-to-Digital Converter (ADC) with up to 12 channels, and an on-chip temperature indicator. The device also offers multiple power-managed operating modes such as Run, Doze, Idle, and Sleep with ultra-low Sleep currents. The PIC16LF1823 uses a 14-bit instruction word RISC architecture with a hardware stack and interrupt controller supporting both core and peripheral interrupt sources. nanoWatt XLP technology provides Sleep currents down to the low-nanoampere range and Run currents in the tens of microamperes per MHz, making the device well suited to battery-powered designs. The integrated peripherals and configurable oscillator eliminate the need for many external components. Typical applications include IoT sensor nodes, wearable fitness and medical devices, remote controls, battery-powered instrumentation, low-power wireless sensor networks, and consumer white goods. The combination of small package, low power, and rich peripherals also makes it suitable for general-purpose logic replacement in mixed-signal products. When designing with this MCU, allocate the budget for the ICD debugging header or pinout, since several I/O pins share analog and debug functions. The LF variant requires a 1.8V-3.6V supply; for designs that need 5V tolerance, use the PIC16F1823 family instead.

PIC16LF1823-I/SL

PIC16LF1823-I/SL - 8-bit 32MHz XLP MCU 3.5KB Flash | Microchip

The Microchip Technology PIC16LF1823-I/SL is an 8-bit PIC microcontroller from the enhanced mid-range family featuring eXtreme Low Power (XLP) technology, offering 3.5KB of Flash program memory, 128 bytes of RAM, and a 32MHz internal oscillator in a 14-pin SOIC package. It integrates 12 I/O pins, supports an operating voltage range of 2.5V to 3.6V (LF variant), and executes instructions in 200ns, providing PIC RISC architecture performance for low-power embedded designs. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, Flash program memory, RAM, peripherals, and I/O onto one die, executing one instruction per cycle under a RISC architecture. The PIC16LF1823 sits within the PIC16 enhanced mid-range taxonomy: PIC16 -> mid-range 8-bit family -> PIC16F1xxx enhanced mid-range -> eXtreme Low Power (XLP) subset. The XLP designation indicates optimized sleep currents below 50 nA typical, making this part ideal for battery-powered IoT nodes, sensor peripherals, and remote controls where quiescent current dominates battery life. Key features include the 32MHz internal oscillator (eliminating external crystals in many designs), 3.5KB Flash self-programmable memory, 128 bytes SRAM, 256 bytes EEPROM, an integrated 10-bit ADC, comparators, PWM modules, EUSART, and I2C/SPI. The XLP technology achieves sleep currents below 100 nA with retention, enabling multi-year coin-cell operation. The 14-pin SOIC package (SL suffix) provides hand-solder-friendly through-hole-compatible footprints and operates across the standard -40C to +85C industrial range, supporting consumer and industrial temperature applications. The PIC16LF1823 uses a Harvard-architecture RISC core with a 14-bit instruction word and 200ns instruction execution at 20MHz, while the LF (low-voltage F) process variant extends operational efficiency at 1.8V-3.6V supply. Core-independent peripherals (CIPs) such as the Configurable Logic Cell (CLC), Numerically Controlled Oscillator (NCO), and Complementary Waveform Generator (CWG) offload tasks from the CPU, further reducing active-mode power consumption and enabling deterministic peripheral operation without waking the core. Typical applications include battery-powered IoT sensor nodes, remote controls, low-power wireless peripherals, energy harvesting designs, wearable health monitors, smart metering, and consumer electronics with segmented LCD or LED interfaces. The compact 14-pin footprint suits space-constrained designs where PCB real estate is at a premium. When designing with this part, ensure decoupling capacitors of at least 100nF are placed within 5mm of the VDD pin, and that unused I/O pins are configured as outputs to minimize shoot-through current. The LF process variant requires supply voltages strictly within 1.8V-3.6V (extended from 2.5V-3.6V typical); for designs targeting 5V operation, select the PIC16F1823 (standard F variant) instead.

The architecture combines a 14-bit instruction word with a 16-level hardware stack and 25-instruction opcode set, balancing code density with deterministic real-time response. Active current is typically in the microampere range at low clock speeds, and sleep currents can drop below 30nA, making the device suited to duty-cycled battery applications. The on-chip 32MHz HFINTOSC eliminates the need for an external crystal in space-constrained designs. Typical applications include battery-powered sensor nodes, wearable fitness/health monitors, low-power IoT endpoints, remote controls, consumer appliances, and small motor-control subsystems. The combination of internal oscillator, EEPROM data storage, and CCP/PWM peripherals enables single-chip implementation of many simple embedded products. When designing with this device, prioritize unused peripheral shutdown, careful ADC acquisition timing, and proper decoupling. Keep VDD traces short, place a 0.1uF bypass capacitor within 5mm of the VDD pin, and use the IDD/datasheet graphs to estimate average current across duty cycles before committing to battery capacity.
