It is built around an enhanced mid-range 8-bit core that delivers high-performance MIPS-per-mW efficiency and is engineered for low-power mTouch® capacitive-sensing front ends and general-purpose embedded designs. The part's small 4x4 mm footprint makes it suitable for space-constrained human-interface panels. The IPC pin (industrial -40C to +125C variant) covers extended industrial temperature range, enabling harsh-environment deployment. A microcontroller (MCU) is a small computer on a single integrated circuit containing a processor core, program memory (Flash/ROM), working memory (RAM), and multiple peripherals such as ADCs, timers, and communication interfaces. The PIC16LF1566 sits inside the hierarchy: 8-bit MCU → PIC16 family → PIC16F XLP → low-power microcontroller → semiconductor IC. It executes instructions at 32MHz / 4 = 8 MIPS, which is sufficient for capacitive touch scanning, simple state machines, and protocol bridging. Key features include up to 23 analog input channels feeding two 10-bit ADCs with hardware CVD (Capacitive Voltage Divider) acquisition, two PWM modules, hardware I2C/SPI/UART peripherals, an integrated temperature indicator, and Microchip's eXtreme Low Power (XLP) technology with nanoWatt XLP sleep currents below 100 nA typical. The two ADCs can operate in tandem to support simultaneous sampling, useful for touch wheel/slider implementations. The 28-UQFN package exposes up to 25 GPIOs through Multi-Voltage I/O (MVIO), enabling direct interface to mixed-voltage sensors without level shifters. The PIC16LF1566 uses a Harvard RISC architecture with a 14-bit instruction word and a hardware stack for deterministic interrupt response. The integrated CVD acquisition engine automates touch-button charging cycles, offloading firmware overhead. Watchdog timer, brown-out reset, and low-voltage programming round out the safety subsystem. Debug access is via the 2-wire ICD interface standard to all PIC16 MCUs. Typical applications include mTouch® capacitive touch panels, IoT edge sensor nodes, battery-powered human-interface devices, LED lighting controllers, and small home-automation modules. The 23-channel ADC chain is well suited to multi-button slider/wheel interfaces, while the XLP sleep modes support coin-cell powered remotes and thermostats. Industrial front-end sampling modules also benefit from the dual-ADC hardware CVD path. When designing with this device, allocate PCB space for the exposed die-pad (EP) on the 28-UQFN package - it must be soldered to a thermal land with sufficient vias for mechanical strength and thermal rating. The MVIO pins require proper decoupling at each power domain. Use the MPLAB X IDE with XC8 compiler for development; Microchip's MPLAB Code Configurator (MCC) auto-generates the CVD and ADC driver code.

It features two on-chip 10-bit high-speed ADCs with automated hardware CVD (Capacitive Voltage Divider) modules supporting up to 34 analog input channels at a sampling rate of 600k samples per second. The 'LF' prefix denotes an extended low-power variant (1.8V-3.6V VDD) using Microchip's eXtreme Low Power (XLP) technology for battery-friendly designs. An 8-bit microcontroller (MCU) is a small computer-on-a-chip built around an 8-bit data bus CPU with on-chip Flash, RAM, and peripherals. The PIC16LF1567 belongs to the broader hierarchy: microcontroller -> embedded microcontroller -> RISC MCU -> PIC16 family -> 8-bit PIC -> semiconductor. The PIC16 core uses a Harvard architecture with separate program/data buses, enabling single-cycle instruction execution except for branches.

Designed for mTouch® capacitive-touch sensing and general-purpose embedded designs, this device integrates two 10-bit ADCs with automated hardware CVD (Capacitive Voltage Divider) modules capable of driving up to 34 analog channels at a combined 600 ksps sampling rate, making it well suited for front-panel touch interfaces and multi-sensor acquisition. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and peripheral interfaces into one package. PIC microcontrollers use a RISC-based Harvard architecture with separate program and data buses, which enables single-cycle instruction execution and deterministic timing critical for real-time control loops. The PIC16LF1567 belongs to the PIC16F156x mid-range MCU family hierarchy: PIC16F → mid-range 8-bit MCU → enhanced mid-range core with C compiler support → PIC16LF156x sub-family focused on mTouch and analog front-end designs. Key features include 14 KB Flash (8K × 14 words), 1 KB RAM, hardware CVD for capacitive touch, two PWM modules, multiple communication peripherals (I²C, SPI, EUSART), and the XLP™ ultra-low-power design with nanoWatt XLP sleep currents. The 10-bit ADC provides up to 34 analog input channels with hardware oversampling and automated sequencing, offloading CPU cycles in touch and sensor applications. The 40-pin PDIP package offers easy through-hole prototyping, breadboard compatibility, and straightforward rework compared to QFN variants. Architecturally, the PIC16LF1567 uses a 14-bit instruction word with a 35-instruction set, providing code density and predictable interrupt latency. Two on-chip op-amps and a hardware CVD module further reduce external component count in touch-sensing front ends, while the integrated mTouch library simplifies firmware development for buttons, sliders, and proximity sensors. Typical applications include mTouch capacitive touch buttons and sliders in appliances, industrial HMI panels, battery-powered sensor nodes, LED lighting controllers with capacitive dimming interfaces, low-power IoT edge nodes, and consumer electronics front-panel interfaces. The wide ADC channel count and hardware CVD also support multi-zone capacitive proximity detection in automotive interior lighting and smart home wall switches. When designing with the PIC16LF1567-E/P, ensure proper decoupling (100 nF + 1 µF) close to VDD/VSS pins and keep the CVD trace length short to minimize touch-sensing noise. Industrial temperature grade (-40 °C to +125 °C) supports harsh-environment deployment, but the through-hole PDIP package limits high-frequency signal integrity compared to QFN variants on 4-layer boards.

Architecturally, the device uses a 14-bit instruction word and 8-bit data path, a 32-level hardware stack, and a 31 kHz internal Low-Power RC oscillator in addition to a 32 MHz HFINTOSC. These features let the firmware switch between high-speed active mode and low-power sleep/wake cycles without external crystals, which is essential for touch, sensor, and metering designs that must minimize standby draw. Typical applications include mTouch capacitive touch sensing (buttons, sliders, proximity), LED lighting controllers, low-cost sensor front ends, and small motor-control loops. The dual-ADC with CVD is purpose-built for mutual-capacitance touch panels, while the two PWMs can drive indicator LEDs, dimming chains, or simple DC fan stages. When designing with this MCU, budget for at least 100 nF + 1 uF decoupling close to VDD/AVDD/VSS pairs and route the ICSP/PGD-PGC lines away from switching nodes to keep in-circuit programming reliable. The 32 MHz internal oscillator removes the need for an external crystal in most designs, but applications sensitive to UART baud-rate drift should add a 4 MHz-32 MHz external resonator.

PIC16LF1574-I/ST - 8-Bit MCU, 7KB, 32MHz, 14-TSSOP | Microchip
PIC16LF1574-I/ST

PIC16LF1574-I/ST - 8-Bit MCU, 7KB, 32MHz, 14-TSSOP | Microchip

The Microchip PIC16LF1574-I/ST is an 8-bit RISC microcontroller from the PIC16F family, featuring 7KB (4K x 14) of Flash program memory, 512 bytes of RAM, and a 14-TSSOP package. It operates at up to 32MHz clock speed from a 3V supply and integrates dedicated peripherals including four 16-bit PWMs, a 10-bit ADC, a 5-bit DAC, comparators, CWG (Complementary Waveform Generator), PPS (Peripheral Pin Select), and EUSART for asynchronous/synchronous serial communication. A microcontroller (MCU) is a single-chip computer integrating CPU, RAM, non-volatile program memory, and peripherals. Within the broader taxonomy, an 8-bit MCU is the simplest tier (8-bit MCU -> microcontroller -> embedded IC -> semiconductor), well-suited to deterministic real-time control where cost, latency, and code predictability outweigh raw throughput. The PIC16LF1574-I/ST uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, providing a balance of code density and execution speed for resource-constrained designs. Key features include four independent 16-bit PWMs with hardware timers for high-resolution applications such as LED lighting, motor control, and digital power conversion. The 10-bit ADC handles analog sensing, while the 5-bit DAC provides reference or bias generation. The CWG module simplifies complementary drive patterns (e.g., for MOSFET half-bridges), and PPS allows flexible peripheral-to-pin assignment. EUSART supports RS-232/RS-485 communication, while the MSSP peripheral enables SPI and I2C protocols. The -LF variant denotes an extended low-voltage operating range (1.8V to 3.6V typical) optimized for battery-powered designs. The architecture combines an 8-bit data path with a Harvard-style separate instruction bus, achieving single-cycle execution for many instructions. The 14-bit instruction word allows a broad opcode set with built-in hardware multiply assist, and the Flash-based program memory supports in-circuit serial programming (ICSP) for field updates. Typical applications include high-resolution LED lighting, digital switched-mode power supply control, motor drive, general-purpose sensor/RCIO signal conditioning, and battery-powered IoT nodes. Designers also use it for low-cost RC servo and PWM fan controllers. The combination of CWG and 16-bit PWMs makes it a strong fit for primary-side and secondary-side regulation in compact switchers. When designing, ensure the supply stays within the LF range (1.8V to 3.6V typical; -40C to +85C for the -I industrial grade variant). Decouple VDD with a 100nF ceramic capacitor close to the pin, and route analog/digital grounds properly to avoid ADC/DAC noise coupling.

PIC16LF1574T-I/JQ - 8-Bit MCU, 7KB Flash, 10-bit ADC, 16-UQFN | Microchip
PIC16LF1574T-I/JQ

PIC16LF1574T-I/JQ - 8-Bit MCU, 7KB Flash, 10-bit ADC, 16-UQFN | Microchip

The Microchip Technology PIC16LF1574T-I/JQ is an 8-bit PIC microcontroller in the PIC16F family, featuring 7KB Flash program memory, 512B RAM, a 32MHz internal oscillator, and four 16-bit PWMs, all integrated in a compact 16-pin UQFN (4x4 mm) package. The 'LF' prefix designates the low-power (wide Vdd) variant that supports a 1.8V-3.6V supply range for battery-powered applications, while the 'T' suffix indicates tape-and-reel packaging. The 'I' temperature grade means the part operates from -40C to +85C, and the 'JQ' package code identifies the 16-pin UQFN. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and programmable peripherals. PIC microcontrollers from Microchip are based on a RISC architecture and dominate hobbyist, industrial, and educational embedded markets because of their low cost, simple instruction set, and a free IDE (MPLAB X) supported by a large ecosystem of development tools. The 'LF' line within the PIC16F family specifically targets energy-harvesting and battery applications by trading absolute maximum speed for ultra-low active and sleep currents. Key features of the PIC16LF1574 include four 16-bit Pulse-Width Modulation (PWM) channels with independent timers for high-resolution motor, LED, and power-converter control; a 10-bit Analog-to-Digital Converter (ADC) accessible through the chip's analog input pins; a 5-bit DAC; a Configurable Logic Cell (CLC) for hardware glue logic; and a Numerically Controlled Oscillator (NCO) for precise frequency generation. The device is supported by the Core Independent Peripherals (CIPs) ecosystem that lets designers implement complex timing and signal-processing tasks without CPU intervention. Architecture-wise, the PIC16LF1574 uses a 14-bit instruction word with a two-stage pipeline, eight-level-deep hardware stack, and 49 instructions. It supports in-circuit debugging via MPLAB ICD and programming through MPLAB Xpress or PICkit programmers. The 32MHz internal oscillator delivers 8 MIPS at 3.3V, and the eXtreme Low Power (XLP) sleep current is in the microamp range, which is critical for IoT endpoints that spend most of their life in standby. Typical applications include LED lighting strips and color-mixing fixtures using the 16-bit PWMs, stepper-motor and DC-motor speed control, small switched-mode power supplies, general-purpose remote controls, sensor hubs, and consumer IoT endpoints. The combination of 7KB Flash, 512B RAM, and four high-resolution PWMs gives designers enough headroom for protocol stacks (PWM-controlled IR, RGBW color algorithms) without oversizing the part. Design consideration: at 32MHz the device draws roughly 3 mA active, so derate clock speed to 1 MHz or use sleep modes aggressively when targeting coin-cell or energy-harvested power. Place a 100 nF decoupling capacitor as close as possible to the Vdd pin, and route the exposed thermal pad to a small copper pour to keep the die within the -40C to +85C operating window. This page consolidates distributor pricing, pin-compatible drop-in alternatives in the same 16-UQFN package, and practical design notes that go beyond the manufacturer datasheet.

PIC16LF1574T-I/SL

PIC16LF1574T-I/SL - 8-Bit MCU, 7KB Flash, 12 I/O | Microchip

The Microchip Technology PIC16LF1574T-I/SL is an 8-bit PIC microcontroller from the PIC16LF157x family, operating at up to 32 MHz with 7 KB (4K x 14) of Flash program memory and 512 bytes of RAM, housed in a 14-pin SOIC (SL) package. The device integrates a 10-bit ADC with up to 8 channels, a 5-bit DAC, and Microchip's Core Independent Peripherals (CIPs) such as the 16-bit PWM, Complementary Waveform Generator (CWG), and Configurable Logic Cells (CLC) on-chip. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and a set of peripherals (ADC, timers, communication interfaces) into one package. Within the broader component taxonomy, an MCU belongs to the integrated circuit family, then to the microcontroller sub-family, then to 8-bit microcontrollers, and specifically to the PIC16 family of low-power Flash MCUs from Microchip. The "LF" prefix designates the wide-Vdd, low-power variant suitable for battery-powered and energy-harvesting designs. Key features include 12 I/O pins, an internal oscillator, support for up to 32 MHz operation, 1.8 V to 3.6 V supply voltage, and CIPs that offload tasks like waveform generation and signal conditioning from the core. The integrated 5-bit DAC and 10-bit ADC simplify mixed-signal designs by eliminating external converters in cost-sensitive applications. Technically, the device uses a RISC-based PIC16 core with a 14-bit instruction word and a 16-level hardware stack. The Flash-based program memory supports in-circuit serial programming (ICSP) and self-programming, allowing field firmware updates. The device is engineered for low-power operation with nanoWatt XLP technology, supporting sleep currents down to the nanoampere range, making it suitable for always-on sensor and IoT edge nodes. Typical applications include LED lighting control (using CWG and 16-bit PWM), general-purpose IoT sensor nodes, consumer appliance control, battery-powered instrumentation, and low-cost motor control. Its 14-SOIC footprint makes it well-suited for hand-soldered prototypes and small-batch production. When designing with this MCU, leave adequate ground and supply decoupling (100 nF + bulk) close to the VDD pins, and reserve the ICSP/PGD/PGC pins for in-circuit programming access. If your application needs more memory or peripherals, consider PIC16LF1575 (28-pin) before changing architecture families.
