Key Features

  • Operates from 1.8 V minimum supply at 16 MHz and up to 3.6 V at 32 MHz, enabling battery-powered and energy-harvesting designs with extended run time on a single AAA cell
  • 8K words of self-programmable Flash and 1024 bytes of SRAM support complex firmware with look-up tables, sensor calibration data, and real-time control loops in a single 16-pin IC
  • Integrated 10-bit ADC and DAC channels eliminate external analog conversion components, reducing BOM cost and PCB area for sensor signal acquisition and analog output applications
  • Compact 16-pin VQFN-16 package measuring approximately 4×4 mm enables ultra-dense PCB layouts in wearable, IoT sensor node, and industrial embedded applications

Applications

PIC16LF1705-I/ML is used in battery-powered IoT sensor nodes, wearable health monitors, and smart home devices where its 1.8 V minimum operating voltage and low-power sleep modes extend battery life beyond 1 year on a 3 V coin cell. Its integrated 10-bit ADC makes it a natural fit for industrial sensor signal conditioning, temperature measurement, and motor current sensing in compact embedded control applications. Embedded systems designers also use PIC16LF1705-I/ML in LED driver controllers, HVAC fan speed regulators, and capacitive touch interface modules that benefit from its on-chip DAC and 32 MHz maximum clock rate within the tiny 16-pin VQFN footprint.

Frequently Asked Questions

What are the core processing resources of PIC16LF1705-I/ML and how do they support sensor data logging firmware?

PIC16LF1705-I/ML provides 8K words (14K bytes) of self-programmable Flash for program storage and 1024 bytes of SRAM for runtime data, running the PIC16 instruction set at up to 32 MHz (8 MIPS). This is sufficient to implement a sensor data logger that samples 4 ADC channels at 10 bits and 1 kHz each, stores averaged readings in a 512-byte circular buffer in SRAM, and periodically transmits data over UART at 115200 baud.

How does the 1.8 V minimum supply voltage of PIC16LF1705-I/ML benefit battery-powered IoT designs?

At 1.8 V minimum, PIC16LF1705-I/ML can operate directly from a single alkaline or NiMH cell discharged to its end-of-life voltage, extending usable battery life by 20% to 40% compared to MCUs requiring 2.0 V minimum. In a coin-cell-powered IoT sensor node drawing 50 µA active and 100 nA in sleep, the 1.8 V floor allows the full 225 mAh capacity of a CR2032 to be utilized, translating to over 2 years of battery life at a 1% duty cycle.

Which embedded control applications can leverage the on-chip DAC alongside the 10-bit ADC in PIC16LF1705-I/ML?

The combination of a 10-bit ADC and on-chip DAC in PIC16LF1705-I/ML enables closed-loop analog control without external converter ICs. Typical applications include LED dimmer controllers that read a 0–5 V potentiometer via the ADC and output a 0–3.3 V PWM-averaged analog reference via the DAC, motor speed controllers that measure back-EMF through the 10-bit ADC and generate a variable reference for a gate driver, and temperature controllers that compare a thermocouple ADC reading against a DAC-set threshold.

For a compact IoT PCB, how does the 16-pin VQFN package of PIC16LF1705-I/ML compare to DIP or SOIC alternatives?

The 16-pin VQFN-16 package occupies approximately 4×4 mm = 16 mm² of PCB area, compared to a DIP-16 package that requires about 180 mm² and an SOIC-16 that needs roughly 80 mm². For an IoT sensor PCB constrained to under 3 cm², using the VQFN variant saves more than 60 mm² of board area versus SOIC, freeing space for antenna ground planes, bypass capacitors, and RF modules, at the cost of requiring SMD reflow soldering instead of through-hole hand assembly.
