PIC16LF1507-I/SS 概要
A PIC microcontroller is a compact programmable logic device that combines CPU, memory, and peripherals on a single die, allowing embedded designs to replace discrete logic. Within the broader hierarchy, PIC16LF parts sit above PIC10/12/16 baseline devices and below PIC18/dsPIC parts, in the 8-bit microcontroller class of embedded semiconductors. Microchip's enhanced mid-range core adds C-compiler-friendly instructions and richer peripherals compared to legacy baseline PIC cores.
Key features include 4x standalone PWM channels, a Complementary Waveform Generator (CWG), a Numerically Controlled Oscillator (NCO), 2x Configurable Logic Cells (CLC), an integrated temperature indicator, 25 mA source/sink per I/O, and a 16 MHz internal oscillator. The LF prefix designates the low-voltage 1.8 V to 3.6 V variant with nanoWatt sleep modes, which suits battery-powered and energy-harvesting designs where the standard PIC16F1507 (2.3 V to 5.5 V) would exceed the available rail.
The architecture uses a 14-bit instruction word Flash with self-read/write capability, allowing field upgrades and on-chip data EEPROM emulation. The 10-bit ADC with computation and automated averaging reduces firmware burden, while the CWG module and NCO enable precise waveform synthesis without an external timer IC.
Typical applications include white goods and small home appliances, IoT sensor nodes, LED lighting controllers, low-cost remote controls, and battery-powered consumer devices. Designers choose the LF variant when system voltage is governed by a single Li-ion or 2xAA cell.
When designing with this MCU, decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin and reserve ICSPDAT/ICSPCLK pins for in-circuit serial programming to allow firmware updates after PCB assembly.

主な用途
PIC16LF1507-I/SS の用途: 6 件s: Battery-Powered IoT Sensor Node, White Goods and Home Appliance Control, LED Lighting and Backlight Controllers, Low-Cost Remote Control Transmitter, Consumer Toy and Hobby Electronics, Industrial Sensor Conditioning Module.
Battery-Powered IoT Sensor Node
The PIC16LF1507-I/SS is well-suited to battery-powered IoT sensor nodes because of its 1.8 V to 3.6 V supply range that matches a single Li-ion or 2xAA cell, plus nanoWatt sleep currents that let duty-cycled sensors run for months on a small cell. Its 10-bit ADC with 12 channels and integrated temperature indicator enable direct connection to multiple analog sensors (temperature, light, battery voltage) without external ADC ICs. With 3.5 KB Flash, the firmware can include basic protocol stacks and sensor linearization routines. Place 100 nF ceramic decoupling within 5 mm of VDD and use the internal 16 MHz oscillator to minimize external components.
おすすめ
White Goods and Home Appliance Control
In white goods controllers (washing machines, dishwashers, coffee makers), the PIC16LF1507-I/SS provides the determinism of an 8-bit enhanced mid-range core with enough peripherals to drive relays, triacs, and status LEDs directly. Its 4x standalone PWM channels plus the Complementary Waveform Generator (CWG) handle motor control or dimmer tasks without an external timer IC. The 10-bit ADC reads water level, temperature, and voltage sensing through 12 channels. Industrial -40C to +85C temperature grade supports under-cabinet appliance environments. Layout ICSPCLK/ICSPDAT on dedicated test points for production programming.
おすすめ
LED Lighting and Backlight Controllers
The PIC16LF1507-I/SS drives LED lighting controllers using its 4x PWM outputs and CWG module to generate constant-current dimming waveforms for RGB or white LED strings. The NCO can synthesize additional frequency clocks for triac dimming compatibility. Running from 1.8 V to 3.6 V lets the MCU share a low-voltage rail with the LED driver ICs in battery-powered or USB-supplied luminaires. With 18 I/O at 25 mA source/sink, the MCU can drive logic-level FETs directly. Add a small ferrite bead on VDD to suppress PWM-induced switching noise from affecting the ADC readings.
おすすめ
Low-Cost Remote Control Transmitter
For low-cost RF/IR remote controls, the PIC16LF1507-I/SS provides 3.5 KB Flash for protocol encoding (NEC, RC5, or proprietary), 128 B SRAM for buffering button state, and 128 B EEPROM for storing pairing info. Its nanoWatt sleep draws microamp-level current, so a coin-cell battery can last the lifetime of the product. The integrated NCO can generate a 38 kHz carrier for IR modulation without an external timer. Industrial temperature range supports automotive cabin and outdoor use. Keep the IR LED drive trace short and use a current-limiting resistor sized for the I/O 25 mA sink.
おすすめ
Consumer Toy and Hobby Electronics
The PIC16LF1507-I/SS is widely used in consumer toys and hobby electronics where cost and simplicity dominate. Its tiny SSOP-20 package fits inside compact enclosures, and the internal 16 MHz oscillator eliminates two external crystals. Two Configurable Logic Cells (CLC) let designers implement glue logic in firmware instead of adding 74-series gates, reducing BOM cost. PWM, NCO, and CWG together cover servo control, sound generation, and motor commutation in a single MCU. Provide a Microchip ICSP header even in low-cost designs so field firmware updates are possible during beta cycles.
おすすめ
Industrial Sensor Conditioning Module
The PIC16LF1507-I/SS serves industrial sensor-conditioning modules where its 10-bit ADC, internal voltage reference, and temperature indicator simplify analog front-end design. The CWG and NCO peripherals can synthesize excitation signals for bridge sensors, while 2x CLC blocks implement zero-crossing detection and edge conditioning without discrete logic. Industrial -40C to +85C operation and the LF 1.8 V to 3.6 V supply suit 4-20 mA loop-powered designs using a low-quiescent LDO. Use TVS diodes on analog inputs and isolated ICSP for factory programming when designing industrial field modules.

設計ノート
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin (pin 13), using the shortest possible trace to the adjacent VSS pin (pin 7). The PIC16LF1507-I/SS internally regulates from VDD; an additional bulk capacitor (1-10 uF) on the same node is optional but recommended for noisy supply environments such as motor-driven white goods. Place a ferrite bead or small resistor in series with the supply trace if the upstream 3.3 V regulator is also feeding switching peripherals.
Always reserve pins RA5 (pin 6, OSC1) and RA7 (pin 8, OSC2) for crystal/OSC routing if a high-accuracy external clock is ever needed; even when using the internal 16 MHz oscillator at first prototype, do not place signal traces under these pads so a future crystal can be added without re-spin. Likewise route ICSPCLK (RB7, pin 12) and ICSPDAT (RB6, pin 11) to a 2x3 or 1x5 header with at least one GND pin for in-circuit serial programming; this allows firmware updates after PCB assembly without removing the MCU.
The MCLR pin (RA3, pin 4) is bidirectional on the PIC16LF1507-I/SS and must never be left floating: a 10 kohm pull-up to VDD is mandatory even if reset is not actively used in firmware. Floating MCLR will cause intermittent resets and erratic behavior in noisy environments. Also note that RB4-RB7 pins have interrupt-on-change capability; if not used, disable IOC in firmware to avoid spurious wakeups from nanoWatt sleep. Estimating: with 100 kohm pull-up on MCLR and a 5 nF MCLR cap, reset pulse width is ~5 us - well within the 5 us minimum spec from Microchip datasheet 40001586D.
