PIC16LF1567-E/P - 8-Bit MCU, 14KB Flash, 32MHz, 40-PDIP | Microchip
MPN: PIC16LF1567-E/P ✓ פעילPIC16LF1567-E/P סקירה
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.

יישומים טיפוסיים
PIC16LF1567-E/P מתאים עבור 7 יישוםs: Capacitive Touch Button Panels (mTouch HMI), Battery-Powered IoT Sensor Nodes, LED Lighting Controllers with Capacitive Dimming, Industrial HMI Panels, Consumer Electronics Front-Panel Interfaces, Automotive Interior Lighting and Switch Panels (non-safety), Smart Home Wall Switches and Dimmers.
Capacitive Touch Button Panels (mTouch HMI)
The PIC16LF1567-E/P is purpose-built for mTouch capacitive touch interfaces, integrating two 10-bit ADCs and a hardware CVD module that drives up to 34 analog channels at 600 ksps combined. This hardware offloads touch-scan timing from the CPU, enabling responsive multi-button panels in appliances, access-control keypads, and industrial HMIs without an external touch controller. Designers pair the MCU with Microchip's free mTouch library, which provides reference firmware for button, slider, and wheel sensing.
מומלץ
Battery-Powered IoT Sensor Nodes
With XLP nanoWatt technology and a 1.8 V to 3.6 V VDD range, the PIC16LF1567-E/P is ideal for coin-cell or 2× AA battery-powered wireless sensor nodes. Sleep currents below 1 µA with RTC running extend battery life to multiple years, while 32 MHz active performance (~3 mA at 3.3 V) handles periodic sensor reads and short RF bursts. The 34-channel ADC supports multi-sensor arrays (temperature, humidity, light) on a single MCU, reducing BOM cost.
מומלץ
LED Lighting Controllers with Capacitive Dimming
The PIC16LF1567-E/P combines PWM generation with capacitive touch input, enabling touch-controlled dimming interfaces for smart LED drivers. The two PWM modules can drive MOSFET gates directly for high-current LED strings or feed PWM input signals to external constant-current drivers. With hardware CVD handling slider/wheel gestures, designers can replace mechanical rotary dimmers with sealed touch interfaces ideal for outdoor or kitchen lighting.
מומלץ
Industrial HMI Panels
Industrial operator panels benefit from the PIC16LF1567-E/P's robust peripheral set: hardware CVD for touch buttons, dual ADC for sensor feedback, EUSART/SPI/I²C for PLC or display communication, and PWM for backlight or indicator control. The -40 °C to +125 °C industrial temperature grade supports deployment in factory-floor enclosures, and the 40-pin PDIP package simplifies through-hole assembly for low-volume industrial products with field-serviceable boards.
מומלץ
Consumer Electronics Front-Panel Interfaces
The PIC16LF1567-E/P powers touch-button front panels for coffee makers, microwaves, washing machines, and other white goods where capacitive touch replaces mechanical buttons for sealed, easy-to-clean interfaces. The 14 KB Flash holds touch firmware plus product-specific UI logic, while the 1 KB RAM supports modest display or LED matrix control. The 32 MHz CPU keeps touch latency under 25 ms, providing a responsive user experience.
מומלץ
Automotive Interior Lighting and Switch Panels (non-safety)
While the PIC16LF1567-E/P is not AEC-Q100 qualified, it is well suited for non-safety automotive interior applications such as capacitive door-switch panels, ambient lighting controllers, and rear-seat entertainment keypads. The wide operating temperature range handles cabin extremes, and the 1.8 V to 3.6 V VDD supports direct connection to automotive 3.3 V rails. For safety-critical applications like steering-wheel touch, an AEC-Q100 part must be selected.
מומלץ
Smart Home Wall Switches and Dimmers
The PIC16LF1567-E/P enables touch-based smart-home wall switches that combine capacitive touch buttons/sliders with optional wireless connectivity (via SPI to a colocated RF module). Its 32 MHz CPU and 14 KB Flash can host simple control logic and a wireless protocol stack, while hardware CVD provides reliable touch sensing through plastic or glass faceplates. Sleep-mode power consumption supports battery-free designs powered by energy harvesting.

הערות תכנון
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of each VDD pin (pins 6 and 33 on the 40-pin PDIP). For ADC accuracy and CVD stability, add a bulk 1 µF to 10 µF capacitor adjacent to VDD. The PIC16LF1567-E/P can operate from 1.8 V to 3.6 V, but for optimal ADC linearity keep VDD ≥ 2.4 V or use an external 2.048 V reference on RA3/RA2. Place a ferrite bead or 10 Ω resistor in series with VDD if the supply is shared with switching converters.
Keep CVD trace length below 25 mm and route CVD_TX/CVD_RX pairs symmetrically with ground shielding to minimize parasitic capacitance. Per the Microchip mTouch design guide, maintain a guard trace around each touch electrode connected to a low-impedance analog ground (VSS). Avoid routing digital signals (SPI, PWM) parallel to CVD traces to prevent crosstalk. Place the CVD series resistor (typically 1 kΩ to 10 kΩ) as close to the MCU pin as possible.
Estimated: For a 32 MHz clock at 3.3 V, the PIC16LF1567-E/P active current is approximately 3 mA; at full peripheral load (ADC + CVD scanning + EUSART active), expect 4 mA to 5 mA. Avoid leaving floating ADC pins unconfigured - this wastes current and can inject noise. Configure unused pins as digital outputs driven low. Do not connect MCLR directly to VDD without a pull-up (10 kΩ typical); the ICSP programmer requires MCLR to be driven high for normal operation but pulled low for reset.
The 40-pin PDIP package has a thermal resistance around 50 °C/W (theta_JA) which is adequate for the PIC16LF1567-E/P's typical 3 mA to 5 mA active current (≈15 mW power dissipation). No heatsink is required for standard mTouch or IoT applications. In enclosed industrial enclosures above 60 °C ambient, verify junction temperature using Tj = Ta + (Pd × theta_JA) to ensure it stays below 125 °C. The PDIP package offers better high-temperature margin than QFN packages due to its lead-frame construction.
