PIC16F1615-I/JQ - 8-bit 32MHz MCU, 14KB Flash, 16-UQFN | Microchip
MPN： PIC16F1615-I/JQ ✓ 啟用中PIC16F1615-I/JQ 概覽
A microcontroller (MCU) is an integrated circuit containing a CPU core, program memory (Flash), data memory (RAM), and on-chip peripherals such as timers, ADCs, and communication interfaces. The PIC16F1615 belongs to the 8-bit PIC16 family within Microchip's 8-bit microcontroller portfolio, which sits hierarchically under the broader PIC architecture, microcontrollers, embedded controllers, and finally the semiconductor category. The 16-pin UQFN package makes it suited for space-constrained designs where a low pin count PIC with rich analog features is required.
Key features of the PIC16F1615-I/JQ include 14 KB Flash, 1 KB RAM, 256 B EEPROM, 12 I/O pins, 1.8V-5.5V wide operating voltage, internal 32 MHz oscillator, 10-bit ADCC, two CCP modules, two CLC blocks, ZCD, WWDT, CRC, and high-temperature operation up to 125 °C. The XLP designation indicates ultra-low-power Sleep currents in the nA range with active mode current below 50 µA/MHz, making it ideal for battery-powered applications.
Architecturally, the PIC16F1615 uses a RISC-based 8-bit PIC core with hardware Multiply and a 14-bit instruction word. The integrated ADCC automates averaging, burst accumulation, and threshold comparisons without CPU intervention, while the 24-bit SMT enables precise time-of-flight or capacitive sensing measurements. Functional Safety (FuSa) features such as WWDT, CRC memory scan, and dedicated error peripherals support IEC 61508 SIL-2 capable systems.
Typical applications include small motor control (fan, pump, BLDC), LED lighting control with ZCD-based TRIAC dimming, capacitive touch / proximity sensing via CLC + SMT, battery chargers, sensor nodes in IoT edge devices, and general-purpose industrial control with safety diagnostics. The 16-UQFN footprint suits wearables, sealed sensor modules, and miniaturized industrial nodes.
When designing with this MCU, ensure the exposed pad is soldered to the PCB ground plane for thermal dissipation and electrical reference. Use MPLAB X IDE with XC8 compiler and MPLAB Code Configurator (MCC) for rapid peripheral setup. For functional safety designs, consult the FuSa user guide and the FMEDA document for failure-rate budgeting.

典型應用
PIC16F1615-I/JQ 適用於 6 應用s: Small Motor Control (Fan / Pump / BLDC), TRIAC-Dimmable LED Lighting with ZCD, Capacitive Touch / Proximity Sensing, Battery-Powered IoT Sensor Nodes, Functional Safety Industrial Sensors, Consumer Appliance Control Boards.
Small Motor Control (Fan / Pump / BLDC)
The PIC16F1615's 32 MHz core, 24-bit SMT, two CCP modules, and 10-bit ADCC make it well suited to closed-loop control of small brushless DC, brushed, or AC induction motors. The CLC blocks allow glue-less hardware commutation logic while the SMT precisely measures back-EMF zero-crossings for sensorless control. Functional Safety peripherals (WWDT, CRC, BOR) help meet IEC 60730 class B for appliance motor drives, and the 16-UQFN footprint fits inside the tight motor-end enclosure of a fan or pump.
推薦
TRIAC-Dimmable LED Lighting with ZCD
The integrated Zero-Cross Detection (ZCD) peripheral detects mains-voltage zero crossings without external optocouplers or signal conditioning, enabling phase-controlled TRIAC dimming of LED lamps. Two CCP modules generate the PWM light output and the trailing-edge phase-angle modulation needed for compatibility with legacy dimmers. The 12 I/O pins handle SPI or I2C interface to a wireless module, an ambient-light sensor input, and a status LED. With XLP active currents <50 µA/MHz and a 16-UQFN that fits inside a GU10 form factor, this part is a strong choice for smart bulbs and downlights.
推薦
Capacitive Touch / Proximity Sensing
The Configurable Logic Cells (CLC) combined with the 24-bit SMT enable hardware-accelerated capacitive touch sensing without continuous CPU intervention. The 10-bit ADCC supports high-resolution proximity measurements for water-resistant touch through glass or plastic overlays. The XLP sleep current <30 nA makes the design practical for battery-powered IoT buttons and proximity-triggered wakeup. Functional Safety peripherals support industrial control panels that must self-diagnose for stuck- or stuck-on keys.
推薦
Battery-Powered IoT Sensor Nodes
The 1.8 V minimum operating voltage allows direct connection to single-cell Li-Ion, two-cell alkaline, or coin-cell battery stacks. The XLP sleep current below 30 nA enables years of battery life in periodic-transmission sensor applications such as utility meters or HVAC sensors. The 14 KB Flash accommodates the full LoRaWAN stack with room for application logic. The 16-UQFN footprint enables sealing inside IP67 enclosures for outdoor deployment, and the AEC-Q100 qualified variant (PIC16F1615T-I/JQVAO) is suitable for automotive sensor nodes.

Functional Safety Industrial Sensors
Functional Safety peripherals - Windowed WDT, CRC memory SCAN, hardware error-out, and Fail-Safe Clock Monitor - let the PIC16F1615 target IEC 61508 SIL-2 capable designs for industrial sensors and process-control transmitters. The 24-bit SMT provides high-resolution measurements of process variables, while the 10-bit ADCC captures analog inputs from pressure, temperature, or flow sensors. The exposed-pad UQFN package offers solid thermal performance for the 125 °C ambient industrial temperature range, and Microchip's FMEDA report supports the safety case documentation.
推薦
Consumer Appliance Control Boards
The combination of small footprint, 14 KB Flash, 12 I/O, and integrated CLC and ZCD makes the PIC16F1615 ideal for white-goods control boards like washing machines, microwave ovens, and small kitchen appliances. The CRC peripheral detects corrupted program memory for IEC 60730 class B compliance, while the 10-bit ADCC reads sensor inputs from temperature, water-level, and current sensing. Two CCP channels drive TRIAC outputs for AC load switching and motor speed control in a compact, cost-effective BOM.

設計說明
The 16-UQFN (4x4 mm) exposed pad must be soldered to the PCB ground plane to provide electrical reference and thermal dissipation. Estimate: the exposed pad reduces θJA from ~85 °C/W to ~40 °C/W for 1 oz copper, and ~25 °C/W for 2 oz copper pours (estimated: based on standard UQFN thermal modeling). Apply 8-12 thermal vias under the pad for best results.
Do not skip the decoupling capacitors. Place a 100 nF ceramic between VDD (pin 16) and VSS (pin 7) as close as physically possible to the pins - within 3 mm. Add a bulk 1 µF to 10 µF ceramic at the IC supply trace for noise immunity. Without proper decoupling, the 32 MHz oscillator is susceptible to VDD ripple that can manifest as timing jitter in PWM outputs and ADC readings.
Isolate the analog and digital ground domains on the PCB. Use a star-ground topology or split AGND/DGND planes joined only at the MCU's VSS pin to prevent digital switching noise from coupling into the ADCC measurements. Keep ADC traces short and route them away from PWM signal lines to minimize crosstalk. The ZCD pin (RA2) should be routed away from high-frequency switching nodes.
For battery-powered designs, leverage the XLP sleep modes (Sleep, Doze, and Idle). The 32 MHz core draws <50 µA/MHz active, but Sleep current is less than 30 nA with WWDT disabled. Use periodic wake-up from WWDT or RTCC to minimize average consumption. Estimated battery life for a 220 mAh CR2032 with 0.1% duty cycle is approximately 8-10 years, depending on sensor peripheral current draw.
When using ICSP (In-Circuit Serial Programming), isolate the ICSPDAT/ICSPCLK lines from sensitive analog inputs during programming pulses. Microchip recommends series resistors (typically 4.7 kΩ) on PGC/PGD for production programming paths. For ICD debug, ensure no series resistance above 1 kΩ on PGC/PGD to maintain signal integrity at the 5 MHz debug clock rate.
