PIC16F1709-E/SS 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and a set of peripherals such as timers, communication interfaces, and analog blocks. The PIC16F1709 belongs to the 8-bit PIC® microcontrollers family, which sits within the broader hierarchy of microcontrollers -> embedded processors -> semiconductor ICs. Its enhanced mid-range core uses a 14-bit instruction word and a 16-level hardware stack, providing deterministic interrupt response and low active current.
Key features include two on-chip operational amplifiers, a 10-bit ADC with up to 12 channels, a 5-bit/10-bit DAC, two 8-bit timers and one 16-bit timer, enhanced PWM with four outputs, and Core Independent Peripherals such as the Configurable Logic Cell (CLC), Complementary Output Generator (COG), Zero Cross Detect (ZCD), and Peripheral Pin Select (PPS). These features let designers implement sensor conditioning, power-factor correction, lighting control, and signal generation with minimal external components.
Typical applications include LED lighting drivers, battery chargers, smart sensors, IoT edge nodes, and consumer appliance control panels. The XLP deep-sleep current of typically < 50 nA with retention enables multi-year coin-cell operation for remote wireless sensor nodes and metering.
When designing with this MCU, ensure the ICSP programming header does not interfere with PPS remapped peripherals and leave the ZCD pin floating when unused to avoid spurious triggers. Always confirm that the chosen SSOP footprint is the 5.30 mm body variant.

主な用途
PIC16F1709-E/SS の用途: 6 件s: LED Lighting Drivers, Battery-Powered IoT Sensor Nodes, Smart Sensor Signal Conditioning, Consumer Appliance Control Panels, Power Factor Correction (PFC) Front Stage, Portable Medical Monitoring Devices.
LED Lighting Drivers
The PIC16F1709-E/SS is well suited for LED lighting driver designs because of its four enhanced PWM channels, Complementary Output Generator (COG), and Zero Cross Detect (ZCD) peripheral. The COG can synthesize dead-band-controlled complementary drive signals for half-bridge LED topologies without CPU intervention, freeing the core for dimming algorithms and DMX or DALI protocol handling. The on-chip op-amps condition current-sense shunt voltages for closed-loop constant-current regulation. Operating from 2.3 V to 5.5 V, the MCU can be powered directly from a single-cell Li-ion or a 3.3 V/5 V regulated rail. The 20-pin SSOP package keeps the BOM footprint compact enough for retrofit lamp form factors.

Battery-Powered IoT Sensor Nodes
With XLP deep-sleep current below 50 nA and 2.3 V to 5.5 V operation, the PIC16F1709-E/SS enables multi-year coin-cell battery life for IoT sensor nodes. The on-chip 10-bit ADC with 12 channels multiplexes multiple sensors (temperature, humidity, light), while the two rail-to-rail op-amps provide front-end amplification for low-output transducers without external active components. The 14 KB Flash accommodates LoRaWAN or BLE-link firmware stacks, and PPS allows flexible pin assignment so the same SSOP-20 board can serve multiple SKUs. Wake-up from sleep via interrupt-on-change supports event-driven sampling for HVAC, agriculture, or smart-building telemetry.
おすすめ
Smart Sensor Signal Conditioning
The PIC16F1709-E/SS integrates two rail-to-rail on-chip operational amplifiers, a 10-bit ADC, and a 5/10-bit DAC in a single SSOP-20 device, dramatically reducing external component count for transducer-interface designs. Photodiode transimpedance, thermistor bridges, and load-cell strain-gauge front ends can all be implemented with the internal op-amps plus a handful of precision resistors. The Peripheral Pin Select (PPS) lets engineers remap ADC channels and op-amp I/O to optimize PCB routing on densely populated sensor boards. The 32 MHz instruction throughput is sufficient for software-based linearization and digital filtering at sample rates up to 100 kS/s.
おすすめ
Consumer Appliance Control Panels
The PIC16F1709-E/SS delivers the right combination of 14 KB Flash, 1024 bytes SRAM, four PWM outputs, and a wide -40 °C to +125 °C operating range for consumer appliance control panels such as washing machines, dishwashers, and microwave ovens. The CLC and COG peripherals enable cap-touch-free user-interface logic and triac-fired heater timing, while the 10-bit ADC monitors motor current and temperature. Compared with discrete logic controllers, this single-chip solution reduces BOM cost by 30-40% and supports in-field firmware updates via self-programmable Flash. The SSOP-20 package fits inside the tight enclosure constraints of slim-line appliance fascia designs.
おすすめ
Power Factor Correction (PFC) Front Stage
The PIC16F1709-E/SS excels in digital Power Factor Correction (PFC) front-stage controllers thanks to its high-speed 10-bit ADC, two on-chip op-amps, and the Complementary Output Generator (COG) peripheral. The COG produces dead-band-corrected complementary gate-drive signals for the boost PFC MOSFET with sub-microsecond timing precision, while the internal op-amps condition the current-sense shunt and input-voltage divider without external active components. CLC implements hardware-level cycle-by-cycle current limiting without CPU latency, and PPS allows flexible pin mapping to optimize the high-voltage board layout. Operating from 2.3 V to 5.5 V the MCU can be biased from the auxiliary 5 V or 3.3 V supply rail.
おすすめ
Portable Medical Monitoring Devices
With XLP low-power operation, 1024 bytes SRAM, and 14 KB Flash, the PIC16F1709-E/SS supports portable medical monitoring applications such as pulse oximeters, digital thermometers, and personal ECG patches. The two on-chip rail-to-rail op-amps condition the photoplethysmography (PPG) or ECG electrode signals, while the 10-bit ADC digitizes them at sample rates adequate for heart-rate trending. The 20-pin SSOP footprint fits within disposable-form-factor enclosures, and the extended -40 °C to +125 °C operating range supports both refrigerated storage and skin-contact thermometry. While this part is not FDA-cleared, it provides a low-power MCU platform suitable for Class I/II accessory devices.

設計ノート
Estimated: The PIC16F1709-E/SS in 20-pin SSOP requires a 5.30 mm body footprint with 0.65 mm pin pitch. Place a 100 nF decoupling capacitor within 3 mm of the VDD pin (pin 12) and a 10 µF bulk capacitor near the ICSP header. Keep the ICSP connector traces short and isolated from PWM outputs to avoid programming glitches during in-circuit debug.
When using the on-chip 10-bit ADC, place a 100 nF bypass capacitor directly on the VREF+ pin (RA3) if used as an external reference, and avoid routing high-frequency switching signals adjacent to analog traces. For best ADC accuracy, use the dedicated AVSS/VDD pair where available and oversample in firmware to achieve effective >12-bit resolution.
Do not leave the ZCD pin (RA2) floating when the peripheral is enabled, or spurious triggers will wake the MCU from sleep and drain the battery. Always configure PPS to remap peripherals before enabling the relevant output, since the default pin mapping may conflict with the chosen PCB layout. ICSP programming requires MCLR to be pulled high through the recommended 10 kΩ resistor and a diode to VDD for high-voltage programming.
For battery-powered IoT designs using XLP deep-sleep, disable all unused peripherals via PMD registers, switch the system clock to LFINTOSC (31 kHz) before sleep, and configure all wake-up sources with edge-detection interrupts. The XLP deep-sleep current of typically < 50 nA enables multi-year battery life when combined with infrequent sensor sampling and short active-mode processing bursts.
