PIC16LF1567-E/P - 8-Bit MCU, 14KB Flash, 32MHz, 40-PDIP | Microchip

The Microchip Technology PIC16LF1567-E/P is a low-power 8-bit PIC microcontroller from the PIC® XLP™ 16F family, delivering 32 MHz CPU performance, 14 KB of Flash program memory, 1 KB of RAM, and 10-bit ADC peripherals in a 40-pin PDIP (through-hole) package. 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. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes beyond what is in the Microchip datasheet (40001817B), giving engineers a faster path from selection to prototype.

The Microchip PIC16LF1567-E/PT is a low-power 8-bit PIC microcontroller built on the enhanced mid-range PIC16 CPU core, delivering 32 MIPS at 32 MHz and packaged in a 44-pin TQFP (10x10 mm) with 14 KB of Flash program memory and 1 KB of SRAM. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), working data memory (RAM), peripheral interfaces, and I/O pins into one device. PIC16-family MCUs are 8-bit RISC Harvard-architecture controllers from Microchip, optimized for low-power, deterministic embedded designs. The PIC16LF1567 sits in the company's XLP (eXtreme Low Power) lineage, making it suitable for battery-powered and energy-harvesting applications. Headline specifications include two on-chip 10-bit high-speed ADCs with hardware CVD (Charge-Voltage Discharge) acquisition, supporting up to 34 analog input channels and a combined throughput of 600k samples per second, plus two PWM modules and multiple communication peripherals (I2C, SPI, EUSART). The /LF process variant guarantees operation down to 1.8V on VDD, with typical active current well below 1 mA per MHz, and the -E suffix designates the Extended (-40C to +125C) industrial temperature range. 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.

The PPS peripheral-pin-select routing eliminates pin-lock constraints common on simpler PIC16 parts and supports EUSART communication for both legacy and modern serial links. The architecture combines an enhanced mid-range 14-bit instruction core, hardware multiplier, and configurable clock tree (HFINTOSC up to 32 MHz) to deliver deterministic interrupt response and predictable timing. The "LF" prefix indicates a wide low-voltage operating range down to 1.8V (with full Flash operation to 3.6V) making it suitable for two-cell battery and energy-harvesting designs. Typical applications include LED lighting controllers, sensor conditioning front-ends, small motor/valve drivers, USB-to-UART bridges using the EUSART, and battery-powered IoT sensor nodes. The 14-SOIC footprint suits hand-solderable prototypes and high-density through-hole-replacement layouts where a TSSOP is too small. Designers should consult the device-specific MPLAB X IDE project templates and the PIC16F1574 family datasheet for pin-mapping of PPS channels and for the specific relationship between the CWG and PWM modules when planning synchronous rectification stages.

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

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.

A PIC (Peripheral Interface Controller) microcontroller is a family of 8-bit RISC-based microcontrollers originally developed by General Instrument's Microelectronics Division in 1975 and now manufactured by Microchip Technology. PIC microcontrollers sit within the broader hierarchy of embedded controllers -> microcontrollers (MCUs) -> microprocessors and semiconductors. The PIC16 series specifically targets mid-range applications, sitting between the smaller PIC10/12/14 series and the higher-performance PIC18/24/dsPIC families, and is widely used in low-cost, low-power embedded designs where deterministic real-time behaviour and simple peripheral integration matter more than raw compute throughput. Key features include four 16-bit PWMs with independent timers for high-resolution applications such as LED lighting, a 10-bit ADC with multiple channels, a 5-bit DAC, a Configurable Waveform Generator (CWG), Peripheral Pin Select (PPS) for flexible signal routing, and an EUSART for serial communication.

Architecturally, the device uses a Harvard RISC core with a single-cycle instruction execution at 32 MHz (8 MIPS), 49 instruction set, and a 14-bit instruction word. The integrated 32 MHz internal oscillator reduces external component count. A wide array of communication peripherals includes I2C, SPI, and UART with Enhanced Addressable USART support, plus a configurable Logic Cell Module and Numerically Controlled Oscillator for custom digital logic synthesis. Typical applications include LED lighting drivers, white goods and small motor drives, general-purpose low-cost embedded control, sensor interface controllers, and battery-powered IoT devices. The industrial temperature grade also makes it suitable for factory automation and HMI front-ends. When designing with the PIC16LF1575, verify that the 1.8V minimum VDD does not collide with the 3.3V external logic rails your design uses - the LF (low-voltage) family is intentionally voltage-limited compared to the standard F (3.0V-5.5V) PIC16F1575. Plan input/output pin budgeting against the 14-pin SOIC package; this variant exposes 12 I/O.

PIC16LF1575-I/ST

PIC16LF1575-I/ST - 8-Bit MCU, 14KB Flash, 32MHz, TSSOP-14 | Microchip

The Microchip Technology PIC16LF1575-I/ST is an 8-bit PIC microcontroller featuring 14KB Flash program memory, 1KB RAM, and a 32MHz internal oscillator, housed in a 14-pin TSSOP package. The LF variant is the low-voltage (1.8V-3.6V) CMOS part intended for battery-powered and energy-harvesting designs. The device integrates four 16-bit PWMs (a defining feature of the PIC16(L)F157x family), a 10-bit ADC, and the standard enhanced mid-range PIC16 core, making it well-suited to LED lighting, motor control, and general-purpose analog sensing. An 8-bit PIC microcontroller is a single-chip computer built on a Harvard-architecture RISC core. The PIC16 family sits in Microchip's mid-range portfolio, between the PIC10/12 baseline series and the PIC18 enhanced series, and is widely used in cost-sensitive embedded designs. Within power management, PIC MCUs commonly provide supervisor, sequencing, and PWM control functions; within the MCU taxonomy, the PIC16LF1575 belongs to the PIC16(L)F157x sub-family distinguished by its 16-bit PWM peripherals rather than the typical 10-bit PWM modules of standard PIC16F devices. Key features include four independent 16-bit PWM channels with dedicated timers, a 10-bit Analog-to-Digital Converter with up to 8 input channels, an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), and two comparators. The core runs up to 32MHz providing 8 MIPS, and the 14KB self-programmable Flash supports in-application updates. This device is commonly used in LED lighting controllers, general-purpose sensor interface boards, low-cost motor drive signal generators, and as a companion MCU for supervisory housekeeping in larger systems. When designing, evaluate the internal oscillator's tolerance against any timing-critical UART or PWM requirement; an external crystal or the internal 32kHz LFOSC may be required for tight accuracy. The TSSOP-14 footprint requires adequate thermal relief and a clean analog ground path for ADC accuracy.

PIC16LF1575T-I/JQ

PIC16LF1575T-I/JQ - 14KB Flash 32MHz 8-bit MCU | Microchip

The Microchip PIC16LF1575T-I/JQ is an 8-bit PIC16 microcontroller built around an enhanced mid-range core that runs up to 32 MHz, with 14 KB (8K x 14 words) of Flash program memory and 1 KB of SRAM, housed in a 16-terminal UQFN (4 mm x 4 mm) package with an exposed pad. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a set of on-chip peripherals (ADC, timers, communication) on one die. MCUs sit at the lowest tier of the embedded-computing hierarchy: microcontroller -> embedded controller -> semiconductor device. They are designed for deterministic, low-power control tasks in cost-sensitive and space-constrained products, where a full application processor would be wasteful. Key features include four 16-bit Pulse-Width Modulation (PWM) channels with independent timers, a 10-bit Analog-to-Digital Converter (ADC), a 5-bit Digital-to-Analog Converter (DAC), a Complementary Waveform Generator (CWG), comparators, Peripheral Pin Select (PPS) for flexible signal routing, and an Enhanced Universal Synchronous/Asynchronous Receiver-Transmitter (EUSART) for serial communication. The /JQ suffix designates the 16-pin UQFN package with exposed thermal pad (HVQCCN, 0.65 mm pitch). The PIC16LF1575 architecture uses a 14-bit instruction word, modified Harvard memory organization with separate program and data buses, and on-chip oscillator calibration. Wide operating voltage (1.8 V to 3.6 V) and nanoWatt XLP deep-sleep modes make the part well-suited to battery-powered designs where quiescent current is critical. Typical applications include LED lighting, stepper motor control, switched-mode power supplies, battery chargers, and consumer / IoT edge-node designs. The 16-pin footprint suits compact PCB modules where every pin must justify its assignment. When laying out this device, keep analog and digital ground returns separate and stitch them together at one point under the exposed pad. Decouple VDD with 100 nF and 1 µF ceramic capacitors placed within 2 mm of the supply pins to keep ADC noise low.

PIC16LF1575T-I/SL - 14KB Flash 8-bit MCU 32MHz | Microchip

The Microchip Technology PIC16LF1575T-I/SL is an 8-bit PIC microcontroller from the PIC16F family, delivering 32 MHz CPU performance with 14 KB (8K x 14 words) of Flash program memory and 1 KB of SRAM in a 14-pin SOIC package. It features the PIC16 CPU core with a modified Harvard architecture, supports a wide operating voltage range from 1.8 V to 3.6 V (LF low-power variant), and integrates a 10-bit ADC plus a 5-bit DAC on-chip. The device ships in tape-and-reel packaging (T/R suffix) with the SL designation denoting the 14-lead narrow-body SOIC. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data bus that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals such as timers, ADC/DAC converters, communication interfaces, and GPIO. MCUs belong to the broader category of microcontrollers -> microcomputers -> embedded processors -> semiconductors. They are the building blocks of embedded systems that perform dedicated control tasks in appliances, sensor nodes, motor drives, and lighting controllers, where deterministic low-latency response and ultra-low standby power are essential. Key features of the PIC16LF1575T-I/SL include 14 KB self-programmable Flash, 1 KB SRAM, 128 B EEPROM emulation area, 12 I/O pins, an enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART), one MSSP (I2C/SPI), up to three 16-bit timers, a 10-bit ADC with 8 channels, a 5-bit DAC with 2 channels, complementary waveform generators (CWG), and Peripheral Pin Select (PPS) for flexible signal routing. The LF process node allows operation down to 1.8 V with very low sleep currents, making the part suitable for battery-powered applications. Architecturally, the PIC16LF1575T-I/SL uses Microchip's enhanced mid-range core with a 14-bit instruction word, hardware multiply, and interrupt-driven priority scheme. The 32 MHz internal oscillator eliminates the need for an external crystal in many designs. The integrated 10-bit ADC and 5-bit DAC plus CWG peripherals make the device attractive for closed-loop control and analog-signal generation without external ICs. Typical applications include LED lighting and color-mixing controllers (CWG + 5-bit DAC), consumer electronics with capacitive-touch user interfaces, battery-powered IoT sensor nodes, small motor and fan speed controllers, and general-purpose replacement of legacy PIC16F parts. Designers often select this part when they need more Flash and more peripherals than a PIC10/PIC12 but want to stay within a 14-pin SOIC footprint. When designing with the PIC16LF1575T-I/SL, ensure that the input voltage stays within 1.8 V to 3.6 V; the LF variant does not operate at 5 V. Place a 100 nF decoupling capacitor as close as possible to the VDD pin, and add a 10 uF bulk capacitor near the regulator. For low-power applications, leverage the LF process to enter Sleep mode with peripherals running and use the on-chip ADC with internal FVR reference to minimize external components. This page synthesizes distributor pricing from DigiKey, Mouser, Newark, Octopart and Hotenda with drop-in alternatives and practical design notes not found in the manufacturer datasheet. Engineers searching for a PIC16LF1575T-I/SL replacement or comparison will find a curated set of same-package drop-in alternatives sourced from the Microchip PIC16LF family and verified cross-reference data.
