PIC16LF1507-I/ML Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and configurable peripherals such as ADCs, timers, PWM channels, and digital I/O on one die. PIC16 series MCUs sit in Microchip's 8-bit PIC architecture hierarchy: PIC16 -> 8-bit PIC -> PIC microcontroller -> microcontroller -> embedded computing -> semiconductor. The 'LF' family specifically targets low-voltage and low-power designs and is favored where coin-cell or Li-ion battery rails of 1.8V-3.6V are present without a boost converter.
Key features of the PIC16LF1507 include 3.5KB self-read/write Flash, 128 bytes RAM, four 8-bit timers and one 16-bit timer, a 10-bit ADC with up to 12 input channels, two Configurable Logic Cells (CLC), a Numerically Controlled Oscillator (NCO), Complementary Waveform Generator (CWG), and an internal 16MHz oscillator. The integrated temperature indicator and 25mA source/sink capability on I/O make it a strong fit for compact, mixed-signal, low-power products.
Architecturally, the device uses a 14-bit instruction word with a single accumulator (W) and a 9-bit program counter; the 16-level hardware stack eliminates the need for software stack management in most routines. The HFINTOSC can be tuned in firmware, and the LFINTOSC provides an ultra-low-power 31kHz source for sleep-mode timing, supporting deep-sleep currents in the microamp range.
Typical applications include consumer IoT battery nodes, e-paper price tags, low-cost remote sensors, simple LED lighting controllers, and space-constrained wearables. Designers also use it as a glue controller in mixed-signal boards where a small 8-bit core is sufficient and BOM cost matters.
When designing with this MCU, mind the absolute maximum Vdd of 4.0V - even brief spikes from a USB charger can latch-up the part. A 100nF decoupling cap placed within 3mm of the Vdd pin is mandatory, and the exposed pad (EP) of the QFN package must be soldered to the ground plane for thermal and electrical performance.

Typische Anwendungen
PIC16LF1507-I/ML ist geeignet für 7 Anwendungs: Battery-Powered IoT Sensor Node, Consumer Electronic Price Tag, Industrial Low-Cost Process Controller, Wearable Health Monitor, Smart LED Lighting Controller, Automotive Interior Accessory Controller, USB-C Power Delivery Decorator.
Battery-Powered IoT Sensor Node
The PIC16LF1507-I/ML's 1.8-3.6V operating range makes it a natural fit for coin-cell and Li-ion battery-powered IoT sensor nodes that must run for years on a single cell. Its 10-bit ADC with up to 12 channels can directly sample temperature, light, and battery voltage through resistive dividers without an external analog front end, while the integrated LFINTOSC and deep-sleep modes drop quiescent current into the microamp range between samples. The 3.5KB Flash comfortably fits a wireless protocol stack plus sensor fusion code. For best results, place the MCU adjacent to its sensor, route Vdd through a 100nF ceramic cap within 3mm of the pin, and use the EP pad for thermal relief.

Consumer Electronic Price Tag
Low-cost e-paper price tags benefit from the PIC16LF1507-I/ML's small QFN-20 (4x4) footprint, low-voltage operation, and modest 3.5KB Flash, which is enough to drive an SPI e-paper panel and run update logic. The CWG and NCO peripherals can synthesize waveforms that some e-paper controllers use for charge-pump driving, eliminating a discrete timer IC. Operating at 1.8V lets the design run directly from a single alkaline or coin cell without boost conversion, raising shelf life. Keep SPI traces short and isolated from the switching node, and ensure the EP pad is soldered to a continuous ground pour to support reliable updates.
Empfohlen
Industrial Low-Cost Process Controller
Factory automation PLCs and distributed IO blocks often need a low-cost local controller that can read analog sensors, drive relays, and interface via UART. The PIC16LF1507-I/ML's 12-channel 10-bit ADC, four PWM outputs, and 18 digital I/O lines deliver enough connectivity for small I/O slices. Its industrial -40C to +85C rating handles plant-floor environments, and the 20 MHz core executes PID loops at acceptable update rates for slow process loops. Place TVS diodes on every external pin, use a ferrite bead on Vdd, and ground the EP pad to a star ground for noise immunity.
Empfohlen
Wearable Health Monitor
Wearables like fitness bands and pulse oximeters require a tiny MCU that can run from a small Li-ion or Li-poly cell at 3.3V nominal and sleep deeply between measurements. The PIC16LF1507-I/ML draws only a few microamps in deep sleep and wakes fast on interrupts, ideal for heart-rate sampling at 1 Hz. Its 10-bit ADC is sufficient for reflective PPG sensor conditioning, and 128 B RAM holds short sample windows. The QFN-20 4x4 mm package fits inside a wristband module. Use a switching buck-boost for stable Vdd under battery droop, and place the EP pad over a quiet analog ground island.
Empfohlen
Smart LED Lighting Controller
Connected LED bulbs and RGBW strips need an MCU that can generate precise PWM dimming while staying cheap. The PIC16LF1507-I/ML's four standalone PWM channels, 16-bit timer, and CWG can synthesize high-resolution dimming waveforms without taxing the CPU. Operating from 3.3V downstream of an AC-DC constant-current driver reduces BOM cost versus 5V designs. The 25 mA source/sink on I/O pins can drive small MOSFETs directly. Use the CLC to implement hardware safety interlocks like thermal foldback, and add a TVS across the LED output for surge protection.
Empfohlen
Automotive Interior Accessory Controller
Although not AEC-Q100 qualified, the PIC16LF1507-I/ML is widely used in non-safety automotive interior accessories such as ambient lighting, USB chargers, and seat comfort modules that run from a regulated 3.3V rail. Its industrial -40C to +85C rating covers cabin temperatures, and the 18 I/O lines can drive multiple LED channels or sense button matrices. Add an external watchdog and reverse-battery protection on Vdd. Pair with a CAN or LIN transceiver for body-network communication, and always fuse the Vdd supply upstream.
Empfohlen
USB-C Power Delivery Decorator
USB-C power banks and small docking stations use a low-cost MCU to handle cable-orientation detection, button debouncing, and LED status. The PIC16LF1507-I/ML can read CC pins through its ADC, control indicator LEDs via PWM, and monitor VBUS through a resistor divider. The 3.5KB Flash holds a small state machine, and the CWG can drive a low-side MOSFET for power-path control. Always add 5V RCC protection on CC lines and a TVS on VBUS; the MCU itself is not 5V tolerant on most pins and needs level shifting.

Wichtigste Unterscheidungsmerkmale
- Lowest-voltage PIC16 in 20-QFN (4x4) with full peripheral set (vs. PIC16F1507-I/ML)
- Industrial temperature grade availability with identical footprint (vs. PIC16LF1507-E/ML)
- On-chip CLC, NCO, and CWG peripherals eliminate external logic (vs. PIC16LF1503-I/MV)
Designhinweise
The PIC16LF1507-I/ML must be supplied from a 1.8-3.6 V source; never connect 5V directly to Vdd. Place a 100 nF X7R ceramic decoupling capacitor within 3 mm of the Vdd pin (pin 18) and a bulk 1-10 uF capacitor near the supply rail. Do not exceed 4.0 V absolute maximum - even brief spikes from USB hot-plug events can permanently latch-up the part. The exposed pad (EP, pin 20) must be soldered to a continuous ground copper pour for thermal relief and ADC noise performance.
Estimated junction-to-ambient thermal resistance for the 20-QFN (4x4) with EP soldered to a 1 square inch ground pour is approximately 35-45 C/W. At typical MCU currents of 5-15 mA, self-heating is negligible. However, if the EP is left unsoldered or only partially connected, junction temperature can rise dramatically under sustained 20 MHz operation, triggering thermal shutdown or causing ADC drift. Always verify EP solder fillet via X-ray or cross-section on first articles.
Keep analog and digital traces physically separated; route the ADC reference voltage (if used) with a guard trace to avoid digital switching noise. The QFN-20 4x4 mm package has 0.5 mm pitch pads - use NSMD pads with a 0.3 mm solder mask opening to prevent tombstoning during reflow. Stitch the EP pad with multiple vias to the inner ground plane for both thermal and electrical performance. Avoid routing high-speed signals under the package to minimize coupling into the ADC.
Common mistakes include using the PIC16LF1507 with a 5V supply (only the PIC16F1507 supports that), forgetting to solder the EP pad, leaving ICSP pins RA0/RA1 unprotected, and not reading the device errata sheet. The PIC16(L)F1507 has known silicon revisions with documented errata - check Microchip's errata document for the specific device ID before locking firmware. Also, configure the unused I/O pins as outputs low (not inputs floating) to minimize sleep current.
The 10-bit ADC on the PIC16LF1507-I/ML is sensitive to Vdd ripple; place a ferrite bead between the digital supply and the analog Vdd rail if a switching regulator is used upstream. Acquire ADC samples at the same point in the PWM cycle to avoid coupling, and average at least 16 samples for any measurement requiring better than 8-bit effective resolution. The internal 16 MHz HFINTOSC is not precision-graded; trim it against the LFINTOSC at production test if UART baud accuracy matters.
