PIC16LF1507-E/ML 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a rich set of peripherals. The PIC16LF1507 belongs to the broader 8-bit microcontroller hierarchy: MCU -> 8-bit MCU -> PIC16 family -> PIC16LF150x sub-family. Its low-power 'LF' lineage uses an enhanced mid-range core with 14-bit instruction width and a modified Harvard architecture, balancing code density against deterministic interrupt latency for real-time embedded tasks.
Key features include 18 digital I/O pins shared with peripheral functions, an integrated 10-bit ADC with multiple acquisition channels, enhanced PWM, configurable logic cells (CLC), a numerically controlled oscillator (NCO), and a 16-bit timer plus 8-bit timers. The device supports in-circuit serial programming (ICSP) and integrates nanoWatt XLP power-saving modes that drop quiescent current to the low nanoampere range, enabling years of operation from a single coin cell.
The device uses Microchip's standard mid-range instruction set with 14-bit-wide program words, providing predictable execution timing. The 20-pin QFN (4x4) package includes a central thermal pad that must be soldered to a PCB copper pour to meet the datasheet thermal specifications; failure to do so can degrade power dissipation capability and long-term reliability.
Typical applications include consumer electronics, IoT sensor nodes, battery-operated remote controls, low-cost motor control, and lighting control. The combination of low voltage, low quiescent current, and the small 4x4 mm QFN footprint suits space- and power-constrained products including wearables and wireless sensor endpoints.
When designing with this part, ensure that the exposed pad is soldered to a sufficient copper area, that decoupling capacitors are placed close to VDD, and that the configuration bits are reviewed to enable the desired peripherals and oscillator mode. Programming can be performed with the MPLAB X IDE and the PICkit or Snap programmer.

일반적인 애플리케이션
PIC16LF1507-E/ML 적합 용도: 6 애플리케이션s: Battery-Operated IoT Sensor Nodes, Consumer Remote Controls, LED Lighting Control, Low-Cost Motor Control, Wearable Health Bands, Industrial Sensor Transmitters.
Battery-Operated IoT Sensor Nodes
The PIC16LF1507-E/ML fits battery-operated IoT sensor nodes because its 1.8 V minimum supply enables direct connection to a single LiSOCl2 or alkaline cell, while nanoWatt XLP sleep modes drop quiescent current to the nanoampere range between transmissions. The 18 I/O pins drive digital sensors, an integrated 10-bit ADC samples analog inputs, and the 3.5 KB Flash holds compact BLE/Zigbee payload builders. Compared with a 3.3 V MCU, the LF variant eliminates the boost converter loss in primary-cell designs, extending operating life by an estimated 30-40%.
추천
Consumer Remote Controls
The PIC16LF1507-E/ML suits consumer IR remote controls because its 1.8 V operation runs directly from two AAA cells, its CLC peripheral generates 38 kHz carrier waveforms without CPU overhead, and the small 4x4 mm QFN-20 footprint fits inside a slim remote housing. NCO provides fine-grained frequency synthesis for IR modulation, while the 10-bit ADC reads battery voltage for low-battery alerts. Dropping the LF part into a design replaces a discrete 555 timer and timer IC with a single MCU, reducing BOM count by 2-3 components.
추천
LED Lighting Control
The PIC16LF1507-E/ML fits LED lighting control because the enhanced PWM module drives high-resolution dimming across multiple channels, the 10-bit ADC reads ambient light sensors and current sense, and the wide -40C to +125C temperature range tolerates enclosed luminaire environments. The QFN-20 (4x4 mm) footprint sits comfortably inside a 60 mm downlight housing, and CLC cells implement over-temperature foldback logic in hardware without CPU cycles. Designers typically pair this MCU with a constant-current LED driver; PWM resolution is the limiting factor for dimming smoothness.
추천
Low-Cost Motor Control
The PIC16LF1507-E/ML supports low-cost brushed DC and small stepper motor control via its enhanced PWM module, 16-bit timer for precise commutation timing, and 10-bit ADC for back-EMF or current sensing. The QFN-20 (4x4 mm) package plus 1.8 V operation enables miniaturized motor boards for toys, small fans, and pump controllers. CLC cells implement hardware protection such as over-current blanking in parallel to firmware; expected performance is suitable for sub-30 W motor loads where cost dominates over precision.
추천
Wearable Health Bands
The PIC16LF1507-E/ML fits wearable health bands because its nanoWatt XLP sleep modes sustain coin-cell life for 1-3 years, the small 4x4 mm QFN-20 footprint fits inside a wristband module, and 1.8 V operation directly powers heart-rate or temperature sensor ICs. The 10-bit ADC samples PPG or thermistor outputs at low duty cycle, while CLC cells wake the MCU only when a sensor threshold is crossed. Compared with a 5 V MCU, the LF variant reduces average quiescent current by an estimated 60% in 1.8 V rail designs.
추천
Industrial Sensor Transmitters
The PIC16LF1507-E/ML serves in industrial 4-20 mA sensor transmitters because the -40C to +125C extended temperature grade tolerates field enclosures, the 10-bit ADC provides adequate resolution for sensor linearization, and the small QFN-20 footprint fits a 2-wire loop-powered head. The 1.8 V minimum supply supports an efficient shunt-regulator-derived rail, and CLC cells implement HART-style FSK modulation without CPU load. Designers typically pair this MCU with a 16-bit sigma-delta ADC front-end when higher accuracy is required for precision pressure or temperature transmitters.

설계 노트
The QFN-20 (4x4) ML package has a central exposed thermal pad that MUST be soldered to a PCB copper pour, ideally connected to a ground plane with multiple thermal vias. Failure to solder the pad results in poor heat dissipation and reduced reliability. The datasheet recommends at least 4 thermal vias (0.3 mm drill) under the pad to a 1 oz copper pour on the opposite side; for high-current GPIO switching, increase the copper area to 100 mm^2 or more.
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 18) with the trace short and wide. Add a bulk capacitor of 1 uF to 10 uF at the regulator output to supply transient currents during ADC conversions and PWM switching. Estimated: assuming 20 mA peak digital transients, a 1 uF bulk holds VDD within 50 mV during a 1 us transient (dV = I*dt/C = 0.02 V). Source: standard decoupling practice.
Route the ICSPDAT (pin 6) and ICSPCLK (pin 5) signals to a programming header with no series resistors or capacitors; any added impedance can prevent in-circuit programming. Keep the ICSP traces short (<50 mm) and away from switching nodes. The MCLR/VPP pin (not bonded out on this device) is internally disabled on PIC16LF1507; programming uses the dedicated ICSP pins. Source: Microchip ICSP specification for enhanced mid-range PIC16.
Do not assume 20 MHz operation at 1.8 V supply - the datasheet frequency-vs-voltage plot restricts CPU frequency to about 4 MHz at VDD = 1.8 V, and 20 MHz requires VDD greater than or equal to 2.5 V. Operating the core at 20 MHz with VDD below 2.5 V causes unreliable execution and Flash programming failures. For designs that must run 20 MHz from a depleted battery, add a boost converter or specify a higher nominal cell voltage.
