PIC16LF1507-E/SS Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and programmable I/O peripherals on one die, enabling compact embedded control in everything from sensor nodes to white goods. Within the PIC® 16F family hierarchy, the PIC16LF1507 occupies the low-pin-count, low-power (LF) node, balancing peripheral richness with the BOM cost targets of cost-sensitive industrial and consumer designs.
Key features include 18 digital I/O pins capable of 25mA source/sink, a 12-channel 10-bit ADC with voltage reference, four standalone PWM channels, two Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), and a Numerically Controlled Oscillator (NCO) for high-resolution frequency synthesis. An integrated temperature indicator and 128 bytes of EEPROM-like data Flash support field calibration and user-preference storage. The NanoWatt XLP technology extends sleep current into the nanoampere range, making the part suitable for battery-powered sensor endpoints.
The enhanced mid-range core delivers 49 instructions and 16-level deep hardware stack, with self read/write Flash capability enabling bootloader-free firmware updates. The internal 16MHz oscillator eliminates the need for an external crystal in space-constrained designs. The PIC16LF1507 uses a 14-bit instruction word with single-cycle execution for most instructions, achieving effective throughput close to 5 MIPS at 20MHz FOSC.
Typical applications include consumer white goods user interfaces, low-cost IoT sensor nodes, LED lighting controllers, battery chargers, small home appliances, and automotive interior accessories (PIC16LF1507-E grade = -40°C to +125°C). The 20-SSOP footprint is drop-in compatible with the SOIC-20 footprint on many reference designs, easing PCB rework.
When designing with this part, allocate a 0.1µF decoupling capacitor within 3mm of VDD, and route the MCLR pull-up (when enabled) directly to VDD. Configure unused I/O as outputs low to minimize quiescent current. The ADC benefits from a 100nF + 10µF analog supply RC network if a separate analog AVSS is used.

Typical Applications
PIC16LF1507-E/SS is suitable for 6 applications: Consumer White Goods User Interface, Battery-Powered IoT Sensor Node, LED Lighting Controller, Small Home Appliance Control, Automotive Interior Accessory, Battery Charger / Power Bank Controller.
Consumer White Goods User Interface
The PIC16LF1507-E/SS fits consumer white-goods UI panels (washing machine, microwave, dishwasher) because its 18 I/O pins at 25mA directly drive LED indicators, 7-segment displays, and keypads without external drivers. The 1.8V-3.6V VDD range allows direct connection to 2xAA backup batteries for clock retention during power loss, while the integrated 10-bit ADC with 12 channels reads multiple potentiometer/thermistor sensors for user input. The CWG peripheral simplifies half-bridge driving of buzzers and small relays, replacing discrete logic with on-die configurable logic. The -40°C to +125°C E grade handles kitchen-environment temperature swings. Designers save BOM cost by using the internal 16MHz oscillator instead of an external crystal, and the NanoWatt XLP sleep modes drop quiescent current into the nanoampere range during standby.
Recommended
Battery-Powered IoT Sensor Node
The PIC16LF1507-E/SS is well-suited for coin-cell or 2xAA battery IoT sensor endpoints because the 1.8V minimum VDD lets the MCU operate directly from a depleted CR2032 cell, while NanoWatt XLP technology drops sleep current below 30 nA. The 10-bit ADC with 12 channels reads temperature, humidity, and battery-voltage sensors without an external AFE chip, and the integrated 16MHz oscillator eliminates crystal cost in space-constrained sensor PCBs. The NCO peripheral generates accurate PWM outputs for IR LED drive or buzzer tones without CPU load. The 3.5KB Flash fits typical sensor-firmware footprints (BLE beaconing, periodic wake-measure-transmit loops). With 18 I/O available, designers route SPI/I2C sensor buses and GPIO interrupt lines without external muxing. The 20-SSOP package is 5.30mm wide - small enough for AA-battery-form-factor sensor sticks.
Recommended
LED Lighting Controller
The PIC16LF1507-E/SS drives entry-level LED lighting controllers thanks to its 4 standalone 10-bit PWM channels and the Complementary Waveform Generator (CWG), which produces dead-band-controlled half-bridge signals for synchronous buck LED driver topologies. The 25mA I/O source/sink directly interfaces with logic-level MOSFET gate drivers, removing the need for external buffers. The CLC cells implement look-up-table color-mixing or dimming curves in hardware, offloading the CPU for smooth fade transitions. The NCO generates high-resolution dithered PWM frequencies above the audible band, eliminating flicker and audible noise in residential dimmers. The wide 1.8V-3.6V VDD range accepts 3.3V regulated rails from offline LED drivers, and the E temperature grade ensures reliable operation inside hot luminaire enclosures.
Recommended
Small Home Appliance Control
The PIC16LF1507-E/SS controls small home appliances such as coffee makers, slow cookers, blenders, and toasters where 18 I/O pins manage keypads, displays, sensors, and triac/SCR-based AC load switching. The CWG peripheral provides complementary PWM with programmable dead time for AC zero-cross triac triggering, while the NCO generates precise 50/60Hz line-frequency references for accurate phase-angle dimming. The 10-bit ADC reads NTC thermistors for temperature feedback, and the 4 PWM channels drive small DC motors, pumps, or solenoid valves. Internal Flash self-read/write capability enables field firmware updates via the appliance's user interface. The wide operating temperature range (-40°C to +125°C E grade) tolerates the thermal environment inside appliance housings, and the 20-SSOP package fits the compact PCB layouts typical of countertop appliances.
Recommended
Automotive Interior Accessory
The PIC16LF1507-E/SS (E grade = -40°C to +125°C) is appropriate for non-safety automotive interior accessories such as ambient lighting strips, cup-holder illumination, seat-position memory switches, or vanity-mirror controllers. The 18 I/O pins and 25mA drive directly switch LED strings, capacitive-touch electrodes, and small DC loads. The CWG with dead-time control safely drives half-bridge MOSFETs for PWM dimming of automotive-grade LED strings. The 1.8V-3.6V VDD operates from the regulated 3.3V accessory rail. The 10-bit ADC with 12 channels reads multiple analog inputs including battery voltage and temperature. For safety-critical functions (airbag, ECU, ADAS), use AEC-Q100-qualified parts such as PIC16F15344-E/P or PIC18F family - the LF1507 is intended for comfort/convenience subsystems only.
Recommended
Battery Charger / Power Bank Controller
The PIC16LF1507-E/SS implements single-cell Li-ion/LiPo charger or power-bank controllers because its 10-bit ADC accurately measures battery voltage and charge current through external sense resistors. The 4 PWM channels and CWG generate switching signals for synchronous buck chargers or boost converters, with the NCO providing high-resolution duty-cycle control for CC/CV charge profiles. The 1.8V-3.6V VDD range directly powers the MCU from a single Li-ion cell without a regulator, and NanoWatt XLP modes drop sleep current below 1µA during shipping/storage. The Flash self-read/write capability stores calibration parameters and battery fuel-gauge tables in non-volatile memory. The 20-SSOP package and -40°C to +125°C E grade fit consumer power-bank enclosures that may experience thermal stress during high-current charging.

- Extended temperature E grade in 20-SSOP (vs PIC16LF1507-E/SO (20-SOIC))
Design Notes
Place a 0.1µF ceramic decoupling capacitor within 3mm of the VDD pin (pin 7) and a second 0.1µF close to VSS (pin 8) to suppress switching transients from the internal oscillator and digital I/O edges. For ADC accuracy, add a 10µF + 0.1µF bulk network on the analog AVSS/VDD path if AVSS is used separately. Estimate: at 20MHz active and 3.3V VDD, typical IDD is around 3-4mA; sleep current with NanoWatt XLP is below 30nA.
Route the MCLR/RA3 pin (pin 1) with a 10kΩ pull-up to VDD and a 100nF cap to VSS to prevent false resets from EMI. Keep the ICSP clock (RB6/pin 18) and ICSP data (RB5/pin 19) traces short and away from switching signals to ensure reliable in-circuit programming. The 20-SSOP package has a 0.65mm pitch - use 0.4mm-wide traces and 0.2mm solder mask dams per IPC-7351 nominal land pattern.
Do not apply voltages above 3.6V to any I/O pin - the LF variant has no 5V tolerance and will latch-up or damage the device. When migrating firmware from PIC16F1507 to PIC16LF1507, verify all peripheral configurations because the LF variant has reduced frequency vs VDD limits at low voltages. The internal 16MHz oscillator drifts ~1% over temperature; for UART timing accuracy >2%, enable the auto-tune feature against a 32.768kHz external crystal.
The 20-SSOP package has theta_JA around 95°C/W in still air - at maximum 5mA active current and 3.6V, worst-case dissipation is 18mW, raising junction temperature only 1.7°C above ambient (negligible). However, in enclosed luminaires or appliance housings with ambient up to 85°C, ensure adequate PCB copper pour on VDD/VSS pins to keep junction below 125°C maximum.
Compliance Information
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified - the E grade (-40°C to +125°C) is rated for industrial/automotive-interior use but does not carry the AEC-Q100 automotive certification. For AEC-Q100-qualified PIC MCUs in safety-critical automotive applications, use PIC16F15344-E/P or PIC18F family.
