- Low minimum supply voltage of 1.8V at 32 MHz enables direct operation from single-cell Li-ion or alkaline battery without a boost regulator
- Integrated ADC and DAC channels on a 14-pin TSSOP body reduce external component count for analog signal conditioning
- 8-bit PIC16 CPU core running at up to 32 MHz delivers deterministic real-time control in a compact TSSOP-14 footprint
- Core-independent peripherals (CIPs) execute tasks autonomously without CPU intervention, extending sleep-mode battery life
- No boundary scan simplifies production test flow for cost-sensitive designs with moderate test coverage requirements
Applications
The PIC16LF1705-I/ST is suited for battery-powered sensors, wearables, and IoT edge nodes where the 1.8V minimum operating voltage maximizes usable battery capacity from coin cells or Li-ion packs. Its integrated ADC and DAC make it practical for smart home appliances, motor speed controllers, and thermostat interfaces requiring on-chip analog processing in a 14-pin TSSOP package. The device also targets low-cost industrial control boards and consumer electronics peripherals needing an 8-bit MCU with a small PCB footprint.

Frequently Asked Questions
How low can the PIC16LF1705-I/ST's supply voltage go, and which battery types benefit from that specification?
The PIC16LF1705-I/ST operates down to 1.8V minimum supply voltage at its full 32 MHz clock frequency, which is low enough to run directly from a discharged AA alkaline cell or a nearly depleted 3V coin cell CR2032. This eliminates the need for a boost regulator in many battery-powered designs, reducing BOM cost by 3-5 components and board area by approximately 20mm² compared to a boosted 3.3V design.
What ADC and DAC capabilities does the PIC16LF1705-I/ST provide for analog signal acquisition tasks?
The PIC16LF1705-I/ST includes a built-in ADC and DAC channel set, enabling on-chip analog-to-digital conversion and voltage generation without external converter ICs. The ADC supports multiple input channels routed through the 14-pin TSSOP-14 package pins, and the DAC can produce reference or control voltages to drive actuators or comparator inputs. This integrated analog capability suits sensor interfaces, 4-20mA loop transmitters, and temperature measurement circuits operating from 1.8V to 3.6V rails.
For a compact motor-control or appliance PCB, how does the TSSOP-14 package size compare to a DIP alternative?
The TSSOP-14 package used by the PIC16LF1705-I/ST measures approximately 5mm x 4.4mm with a 0.65mm pin pitch, compared to a 300mil DIP-14 footprint of roughly 19mm x 7mm. This represents roughly a 75% reduction in PCB area, allowing the microcontroller to fit in space-constrained designs such as smart switches, LED driver controllers, and handheld instruments where board real estate under 25mm² is required.
When is the PIC16LF1705-I/ST a better fit than the PIC16F1705 for a given design?
The PIC16LF1705-I/ST is the low-voltage variant of the PIC16F1705, supporting operation down to 1.8V versus the standard 2.3V minimum of the PIC16F1705. Designers targeting battery-powered or energy-harvesting applications where the supply may drop below 2.3V during discharge should choose the PIC16LF1705-I/ST to avoid brownout resets. Both devices share the same 8-bit PIC16 core, 32 MHz maximum speed, TSSOP-14 package, and peripheral set, so firmware is fully portable between them.
What is the maximum clock frequency of the PIC16LF1705-I/ST, and how does core-independent peripheral support affect throughput?
The PIC16LF1705-I/ST runs at up to 32 MHz, delivering up to 8 MIPS of instruction throughput on its 8-bit PIC16 core. Core-independent peripherals (CIPs) such as the configurable logic cell, PWM, and timer modules operate autonomously at full 32 MHz peripheral clock speed even while the CPU is in sleep mode drawing less than 1µA. This combination allows the device to manage real-time PWM, event capture, and communication tasks without waking the CPU, significantly extending battery life in duty-cycled IoT applications.
