The Microchip Technology PIC16LF1787-E/ML is an 8-bit PIC16 microcontroller built on the company's eXtreme Low Power (XLP) platform, featuring 14 KB of Flash program memory, 1 KB of RAM, and a 32 MHz internal oscillator in a 44-pin QFN (8x8 mm) package. It targets low-power and battery-driven designs that require integrated analog peripherals and small PCB footprints. A PIC microcontroller (MCU) is a compact programmable processor that combines a CPU core, non-volatile program memory (Flash), working RAM, and a rich set of peripherals — timers, ADC/DAC, communication buses, and interrupt logic — on a single silicon die. The PIC16F/LF family uses a RISC-based 8-bit core optimized for deterministic execution, predictable interrupt latency, and ultra-low sleep currents. Within the broader taxonomy, PIC16F/LF sits between smaller PIC10/12/16 baseline devices and larger PIC18/24 MCUs; the "LF" prefix specifically designates the low-voltage (1.8–3.6 V) XLP variants aimed at energy harvesting and battery applications. The 44-QFN package places the entire MCU + analog chain on a tiny surface-mount footprint suitable for space-constrained consumer, industrial, and IoT products. Key features include 14 KB self-programmable Flash, 1 KB RAM, 256 bytes of EEPROM, an integrated 12-bit ADC with up to 14 channels, an 8-bit DAC, two operational amplifiers, comparators, and PWM/capture/compare modules.

XLP technology delivers typical sleep currents in the tens of nanoamps and active currents in the microamp-per-MHz range, enabling years of operation from coin-cell or single-AA batteries. The PIC16LF1787's 8-bit RISC pipeline executes most instructions in one instruction cycle (4 clock cycles), and the 32 MHz internal oscillator removes the need for external crystals in cost-sensitive designs. The on-chip op-amps and 12-bit ADC provide a tightly-integrated analog front-end for sensor conditioning without external active components. Typical applications include IoT sensor nodes, low-power wireless remote controls, battery-powered instrumentation, portable medical devices, and consumer appliances where the MCU must sleep for long periods and wake to perform quick measurements. Designers also use it in HVAC controls, smart meters, and energy-harvesting switches. When designing with this device, remember that the "LF" voltage range is 1.8–3.6 V — it cannot be used on 5 V rails. Decouple VDD with at least 100 nF close to the pin, configure unused pins as outputs (not inputs) to minimize leakage, and use the nanoWatt XLP sleep modes to achieve the lowest quiescent current.

The E in the suffix indicates -40C to +125C extended operating temperature. The architecture is built around the enhanced mid-range 14-bit instruction set with a hardware multiplier and a vectored interrupt controller. The 12-bit ADC with computation (ADCC) automates averaging, oversampling, and threshold comparisons without CPU intervention, which is why it is paired with PSMC blocks for digital lighting and BLDC motor control. CIPs such as CLC, NCO, and SMT continue processing while the CPU is in sleep. Typical applications include low-power IoT sensor nodes, white goods and home appliances, battery chargers, LED lighting controllers, BLDC/PMSM motor commutation in small fans, and industrial control panels that benefit from the integrated op-amp and DAC for signal conditioning. The wide extended-temperature grade makes it usable in outdoor equipment, thermostats, and automotive under-hood sensor interfaces. When designing with this device, plan the LDO and decoupling network carefully - use a 100 nF + 1 uF combination near VDD and AVSS, and place the exposed pad on a contiguous ground copper pour to keep junction temperature within limits. If you do not need the op-amp or PSMC peripherals, consider the pin-compatible PIC16LF1786-E/MV (without the Q suffix) for a lower-cost migration within the same silicon family.

PIC16LF1787-E/PT - 8-bit 32MHz MCU 14KB Flash 44-TQFP | Microchip

The Microchip Technology PIC16LF1787-E/PT is an 8-bit RISC PIC microcontroller from the PIC16F178x family, featuring 14KB Flash program memory, 1KB ROM and a 32MHz CPU core, housed in a 44-pin TQFP (PT) package measuring 10x10mm. The 'LF' prefix indicates a low-voltage, low-power (XLP) variant optimized for battery-powered and energy-harvesting applications, with an extended operating voltage range that supports both 3.3V and 5V rails commonly found in mixed-signal designs. An 8-bit PIC microcontroller is a compact, deterministic Harvard-architecture processor that combines a CPU, non-volatile Flash memory, RAM, and a rich set of peripherals into a single IC. In the wider taxonomy, PIC MCUs sit within the 8-bit microcontroller family, which itself is a subset of microcontrollers under embedded processors. The PIC16LF1787 specifically targets applications requiring low quiescent current, integrated op-amps, comparators, 12-bit ADC, DAC and PWM peripherals, enabling single-chip analog + digital signal chain designs without external components. Key features include 14KB (8K x 14) of self-programmable Flash, 1KB of data EEPROM emulation in ROM, 10-bit and 12-bit ADC channels, multiple 8/10-bit DAC outputs, three operational amplifiers, two comparators, Capture/Compare/PWM (CCP/ECCP) modules, and serial communication peripherals including I2C, SPI and an enhanced USART. The XLP technology provides active current in the microamp range and deep-sleep currents below 100nA, making it suitable for always-on applications where energy budget is critical. The architecture uses a 14-bit instruction word RISC core with a single-cycle ALU and hardware multiply, delivering predictable interrupt latency and deterministic execution. Integrated op-amps allow closed-loop analog feedback without external components, while the high-resolution 12-bit ADC achieves 50 ksps conversion rate with auto-acquisition. The on-chip 32MHz oscillator is factory calibrated to ±1% across voltage and temperature, removing the need for an external crystal in cost-sensitive designs. Typical applications include consumer white goods and home appliances, battery-powered sensor nodes, low-power IoT edge devices, industrial control panels with HMI, automotive body and accessory subsystems, LED lighting controllers, and DC motor control in toys and small appliances. The combination of analog peripherals with low-power operation is the primary reason designers select this part over competing 8-bit MCUs. A critical design consideration is power-supply decoupling: place a 0.1uF ceramic capacitor within 2mm of each VDD pin, plus a bulk 10uF tantalum or ceramic on the rail. The XLP sleep currents assume the brown-out reset (BOR) and watchdog are properly configured; disabling them in firmware is the most common way engineers recover microamp-level standby performance. Programming is supported by MPLAB X IDE with the XC8 compiler, and in-circuit debugging uses ICD 3 or PICkit 4 headers.

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.

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.

Key features of the PIC16LF1787 include a 10-bit ADC with up to 14 channels, 8-bit DAC modules, configurable logic cells (CLC), high-speed comparator, and multiple communication peripherals (I²C, SPI, EUSART). The 'nanoWatt XLP' technology provides sub-microamp sleep currents (typical <50 nA in Sleep mode with RTCC), making the part suitable for battery-powered or energy-harvesting designs where quiescent drain directly determines operating life. The 'T' suffix indicates Tape & Reel packaging; 'I' indicates the industrial temperature grade (-40 °C to +85 °C). Architecturally, the PIC16LF1787 uses a Harvard RISC core with a 14-bit instruction word, allowing single-cycle execution except for branches. 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.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory and programmable I/O peripherals. Within the broader taxonomy, the PIC16LF1788 is a 16-bit instruction word / 8-bit data path RISC MCU, falling under the wider 8-bit MCU category and ultimately the integrated circuit / semiconductor family. The LF prefix designates the low-voltage (1.8 V to 3.6 V) variant of the PIC16F1788 die, while the I/ML suffix denotes the industrial (-40°C to +85°C) temperature range and the 28-pin QFN surface-mount package.

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.

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.

PIC16LF1789T-I/ML

PIC16LF1789T-I/ML - 28KB Flash 8-bit XLP MCU | Microchip 44-QFN

The Microchip Technology PIC16LF1789T-I/ML is an 8-bit PIC microcontroller built on the eXtreme Low Power (XLP) architecture, delivering 32 MHz CPU performance with 28 KB of Flash program memory, 2 KB of RAM, and 256 bytes of EEPROM in a 44-pin QFN (8x8 mm) package with an exposed thermal pad. The part operates across 1.8 V to 3.6 V supply rails, with low-power Sleep currents in the nanoamp range, making it well suited to battery-powered and energy-harvesting designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), working memory (RAM), non-volatile data memory (EEPROM), and a rich set of peripherals such as ADCs, PWMs, communication interfaces, and timers. The PIC16F/LF178x family sits in the PIC16 mid-range tier within the broader 8-bit MCU taxonomy: 8-bit microcontroller -> microcontroller -> embedded IC -> semiconductor. The 'LF' prefix indicates the low-voltage, low-power variant of the PIC16F1789, trading slightly higher maximum frequency for deeper sleep-current savings. Key features include a 12-bit ADC with up to 14 channels, multiple 10-bit PWMs, 2 op-amps, comparators, a 32 kHz low-power internal oscillator, and communication peripherals including EUSART, MSSP (I2C/SPI), and USB support on selected derivatives. The 44-QFN package reduces board area by approximately 50% versus the equivalent 44-pin TQFP, while the exposed pad offers a low thermal-resistance path for sustained CPU activity. Typical applications include portable medical instrumentation, IoT sensor nodes, motor control with FOC algorithms, LED lighting controllers, and low-power industrial sensor hubs. The combination of high-performance analog peripherals and nanoWatt XLP technology enables designs that must wake periodically, sample, compute, and return to deep sleep on a single coin cell for years. When designing with this part, place a 100 nF decoupling capacitor within 2 mm of each VDD/VSS pair and connect the central thermal pad to a continuous ground pour to manage thermal dissipation. The MPLAB X IDE and XC8 compiler provide full toolchain support, and the PICkit 5 or Snap debugger enables in-circuit programming and debugging via the two ICSP pins.
