PIC16LF1567T-I/MV Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile working memory (RAM), and a set of peripheral interfaces onto one die. Within the broader taxonomy, the PIC16LF1567 belongs to the PIC mid-range 8-bit core -> PIC16F family -> PIC16LF156x sub-family -> Microcontroller -> Microcomputer -> Integrated circuit. Mid-range PIC cores use a 14-bit instruction word and a hardware stack, striking a balance between deterministic interrupt response and code density that has been deployed in billions of embedded systems since the 1990s.
Key features of this device include two on-chip 10-bit ADCs with automated hardware CVD acquisition modules supporting up to 34 analog channels at a combined 600 ksps throughput, on-chip mTouch capacitive-touch sensing peripherals for proximity and button implementations, and Microchip's eXtreme Low Power (XLP) technology that allows deep-sleep current draws in the nanoampere range. The 32MHz internal oscillator eliminates an external crystal in many designs, reducing BOM cost and PCB area.
Typical applications include capacitive touch keypads, slider and wheel human-interface modules, multi-channel sensor front ends for IoT end nodes, low-power consumer appliances, and general-purpose mixed-signal embedded control. The combination of dual ADCs and dedicated CVD hardware makes it especially well suited to mTouch proximity sensing where multiple electrodes are scanned automatically without continuous CPU intervention.
Designers should pay attention to the exposed thermal pad (EP) on the UQFN-40 package, which must be soldered to a sufficient copper pour for mechanical reliability and thermal dissipation. Programming is supported via Microchip's MPLAB X IDE with PICkit, ICD, or Curiosity toolchains. For long-term designs, validate that the chosen part is in active production status and confirm pin assignments against the latest revision of the manufacturer datasheet.

Typical Applications
PIC16LF1567T-I/MV is suitable for 7 applications: Capacitive Touch Keypad, Battery-Powered IoT Sensor Node, Multi-Channel Sensor Front End, Consumer Appliance User Interface, Medical Monitoring Accessory, Automotive Interior Touch Panel, Smart Home Wireless Sensor.
Capacitive Touch Keypad
The PIC16LF1567T-I/MV is well matched to capacitive-touch button keypads because its integrated mTouch hardware CVD modules drive and acquire up to 34 electrodes at a combined 600 ksps. The hardware engine handles charge timing automatically, freeing the CPU to debounce, run gesture logic, or sleep - extending battery life. Designers place the device adjacent to the touch sensor PCB, route analog-capable pins to each electrode, and use the 14KB Flash to host state-machine firmware. Compared with a software-scan approach, the PIC16L2 sample timing is deterministic, lowering EMI susceptibility and improving water-wake and proximity performance.
Recommended
Battery-Powered IoT Sensor Node
The PIC16LF1567T-I/MV's XLP nanoampere sleep modes, dual 10-bit ADCs, and 14KB Flash make it a strong fit for coin-cell or 2xAA IoT sensor end nodes. The MCU wakes on an RTC or external interrupt, scans up to 34 analog sensors via the dual ADCs, computes thresholds, transmits via an attached radio, and returns to deep sleep. The 32MHz CPU executes the wake-and-transmit burst quickly, so average current stays in the microampere range. The 40-UQFN package at 5x5 mm fits inside compact sensor modules alongside a small Li-coin cell.
Recommended
Multi-Channel Sensor Front End
In industrial sensor aggregators, the PIC16LF1567T-I/MV's two 10-bit ADCs scan up to 34 channels at 600 ksps combined throughput, providing high channel density in a single chip. Each ADC pair can be sequenced across thermistors, photodiodes, strain gauges, or 4-20 mA loop sensors with on-chip PGA and voltage reference. The 1KB RAM buffers sample windows, and 14KB Flash accommodates Modbus RTU or custom protocol stacks. The 40-UQFN footprint drops onto 5x5 mm sensor hubs adjacent to RS-485 transceivers.
Recommended
Consumer Appliance User Interface
For washing machines, induction cooktops, and small kitchen appliances, the PIC16LF1567T-I/MV drives touch sliders, proximity sensors, and LED feedback via PWM channels while the main control task runs on the 32MHz PIC mid-range CPU. The mTouch CVD hardware handles noise-robust water and steam environments without dedicated touch ICs, reducing BOM cost. With 14KB Flash and 1KB RAM, the device hosts UI state machines, buzzer patterns, and safety lockouts. The 40-UQFN EP package sits behind the front-panel glass on a compact PCB.
Recommended
Medical Monitoring Accessory
Wearable medical accessories benefit from the PIC16LF1567T-I/MV's XLP sleep currents, dual 10-bit ADC throughput, and small 5x5 mm UQFN footprint. The device can wake on a heart-rate or SpO2 sensor interrupt, sample the analog signal chain via the dual ADCs, run threshold checks in firmware, store samples in 1KB RAM, and Bluetooth-bridge them to a host phone. The 14KB Flash fits lightweight wellness algorithm code. The 'I' industrial temperature suffix supports body-worn operating environments from -40C to +85C.
Recommended
Automotive Interior Touch Panel
Although not AEC-Q100 qualified, the PIC16LF1567T-I/MV is widely used in non-safety automotive interior modules such as steering-wheel switch clusters, overhead console controls, and door-panel touch pads. The hardware CVD engine rejects automotive electrical noise from alternators and injectors, and the 32MHz CPU executes debounce, LED feedback, and LIN-bus glue logic. The 40-UQFN EP package at 5x5 mm fits behind thin decorative trim. Designers should validate EMC compliance per their target vehicle platform.
Recommended
Smart Home Wireless Sensor
For Zigbee, LoRa, or Sub-GHz wireless sensor endpoints, the PIC16LF1567T-I/MV serves as the host MCU, waking on radio events, sampling analog sensors via the dual 10-bit ADCs, and managing the radio's SPI/UART interface. XLP nanoampere sleep currents enable multi-year battery life on a single CR2477 coin cell. The 14KB Flash accommodates stack libraries and security keys, and the 40-UQFN EP package drops onto compact sensor PCBs alongside the radio module.

Key Differentiators
- Integrated mTouch hardware CVD engine for up to 34 capacitive-touch channels (vs PIC16F877A (no CVD, software-emulated capacitive-touch))
- Dual 10-bit ADCs at 600 ksps combined sampling rate (vs PIC16F648A (single 8-bit ADC, lower throughput))
- XLP nanoampere sleep currents (vs PIC16F877A (milliampere sleep current))
- Compact 5x5 mm UQFN-40 EP package (vs PIC16F877A in 40-pin PDIP (larger footprint))
Design Notes
The 40-UQFN EP package has an exposed thermal pad on the underside that MUST be soldered to a sufficient copper pour on the PCB - typically at least 1 sq. cm of 2 oz copper tied to VSS. This pad is electrically bonded to VSS and provides the primary thermal path for heat dissipation. Without proper soldering, mechanical reliability suffers and thermal resistance rises, potentially triggering thermal-shutdown behavior under sustained MCU load.
Place a 100 nF decoupling capacitor as close as possible to each VDD pin (pin 19 and pin 40), with the ground return via a short trace to the VSS/EP pad. For noise-sensitive ADC/CVD measurements, add a 10 uF bulk capacitor near the analog VDD supply. Route analog input traces away from switching nodes and digital clock lines, and surround sensitive analog tracks with a ground guard ring tied back to a single star-point ground to minimize ground-loop noise pickup on touch electrodes.
Do not omit the ICSP programming connections: RB6/ICSPCLK and RB7/ICSPDAT must be accessible for in-circuit programming via PICkit or ICD. Add a 10 kohm pull-up on MCLR (pin 39, RE3) to VDD. For mTouch CVD designs, ensure each touch electrode has its own analog-capable GPIO and that the CVD acquisition timing matches the datasheet's CVD register configuration - incorrect timing manifests as false touches or non-linear response.
Route the 32MHz HFINTOSC tracks with care - although internal, the device's clock distribution radiates from the supply and GPIO edges. Keep the MCU ground pour unbroken under and around the package, and place the decoupling capacitors on the same layer as the MCU to minimize loop inductance. For multi-layer boards, dedicate an inner layer to a solid ground plane directly beneath the UQFN-40 footprint.
