PIC16LF1615T-I/JQ 概要
A microcontroller (MCU) in this category is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (SRAM), peripherals, and I/O into one package. MCUs sit at the heart of embedded systems, running firmware that drives sensors, actuators, and communication buses. The 8-bit PIC16 family from Microchip is widely used for cost- and power-sensitive applications because the RISC instruction set, deterministic timing, and rich peripheral mix reduce external component count and extend battery life.
Key features that distinguish the PIC16LF1615T-I/JQ include its 32MHz internal oscillator (so no external crystal is required in most designs), 32MHz MIPS throughput, 1KB SRAM, 256 bytes of EEPROM, XLP sleep currents in the nanoamp range, and a peripheral set optimized for closed-loop control and signal conditioning. The integrated ZCD simplifies AC-line zero-crossing detection for TRIAC dimmers and motor control, while the WWDT and CRC blocks meet functional-safety expectations common in appliance and industrial sensors.
Architecturally, the device is built on an enhanced mid-range 8-bit core with a 14-bit instruction word, hardware multiplier, and interrupt controller supporting both core and peripheral events. The wide operating voltage range (typically 1.8V to 3.6V for the LF variant) and the XLP sleep modes (Doze, Idle, Sleep with RTCC) make it suitable for battery-powered or energy-harvesting products. The internal 32MHz oscillator is factory-trimmed, allowing the device to operate at full speed immediately after power-on without external frequency calibration.
Typical applications include low-cost consumer appliances, LED lighting controllers, battery-operated sensor nodes, fan and pump controllers, simple motor drives, and any compact 8-bit design where code density, peripheral integration, and low quiescent current matter. Industrial-grade variants of the same family are commonly used in HVAC, e-metering, and white-goods user-interface boards.
When designing with this part, keep the UQFN-16 exposed pad soldered to a continuous ground pour for thermal and electrical performance, observe decoupling guidance (typically 100nF plus 1uF bulk near VDD), and reserve the ICSP/ICD pins for in-circuit programming - Microchip recommends not placing large capacitors directly on PGC/PGD to avoid programming interference. The integrated 32MHz oscillator eliminates the cost and PCB area of an external crystal but mandates careful clock-failure-handling firmware if your application depends on accurate long-term timing.

主な用途
PIC16LF1615T-I/JQ の用途: 6 件s: LED Lighting and AC-Line Dimmers, Battery-Operated Sensor Nodes, Home Appliance User Interface Boards, Small Motor and Fan Control, Industrial HVAC Sensor Modules, Consumer Electronics Remote Controls.
LED Lighting and AC-Line Dimmers
The PIC16LF1615T-I/JQ is well suited for LED lighting controllers and AC-line TRIAC dimmers because of its integrated Zero-Cross Detect (ZCD) peripheral, which captures the mains zero-crossing point for synchronous phase-angle control of dimmable lamps. The XLP architecture keeps standby current in the nanoamp range so always-on lighting fixtures meet Energy Star standby limits. With 14KB of Flash and a 32MHz core, the device has headroom for DMX-512 or DALI receive stacks on top of dimming logic. The 1.8V-3.6V supply range matches single-cell Li-ion or 2xAA battery-powered LED drivers. Suggested companion parts include the MCP1700 LDO for the 3.3V rail and an MOC3021 optotriac driver for mains isolation.
おすすめ
Battery-Operated Sensor Nodes
The XLP (eXtreme Low Power) sleep current of the PIC16LF1615T-I/JQ is in the nanoamp range, allowing sensor nodes powered by CR2032 coin cells or 2xAAA batteries to operate for years without replacement. The 10-bit ADC and integrated temperature-indicator peripherals enable simple thermistor, photocell, or moisture-sensor signal conditioning without external analog ICs. The 32MHz internal oscillator gives full throughput when the node wakes for measurement and transmit bursts, then the core returns to sleep. The 16-pin UQFN measures only 4x4mm, fitting easily inside miniature IoT sensor enclosures. Use this part together with an ultra-low quiescent LDO and a sub-GHz or BLE radio module for a complete battery sensor node.
おすすめ
Home Appliance User Interface Boards
White-goods control boards (washing machines, dishwashers, refrigerators, microwave ovens) use the PIC16LF1615T-I/JQ as the user-interface controller for keypads, rotary encoders, LCD segment displays, and indicator LEDs. Its 14KB Flash is enough to host capacitive-touch libraries via firmware alongside menu logic, and the 32MHz core debounces inputs and updates displays without flicker. The hardware CRC block protects stored parameters (cycle counters, fault logs) against bit rot in EEPROM, and the WWDT meets IEC 60335 functional-safety expectations for unattended appliances. The 1.8V-3.6V supply range simplifies integration with 3.3V or 5V-tolerant HMI sub-boards.
おすすめ
Small Motor and Fan Control
The PIC16LF1615T-I/JQ integrates complementary PWM outputs, comparators, and the ZCD peripheral, making it a compact controller for small brushed DC motors, fans, pumps, and solenoid drivers. The 32MHz core provides the MIPS bandwidth for field-oriented control or simple PI loops with cycle-by-cycle current limiting via the on-chip comparator. The XLP sleep modes keep standby power negligible when the motor is idle. Designers can use the on-chip 10-bit ADC for back-EMF sensing or for closed-loop current monitoring through a low-side shunt. Pair this MCU with a DRV8870 or similar H-bridge driver rated for the motor current.
おすすめ
Industrial HVAC Sensor Modules
Industrial HVAC systems use distributed sensor modules (temperature, humidity, CO2, airflow) that require deterministic 8-bit processing and a wide industrial temperature range. The PIC16LF1615T-I/JQ operates from -40C to +85C and hosts a 10-bit ADC plus PWM outputs for local control loops. The hardware CRC and WWDT improve field reliability in electrically noisy HVAC cabinets. The 16-pin UQFN allows the controller to be placed directly on the sensor PCB, reducing wiring and improving signal integrity. Its low power consumption also fits solar-powered or energy-harvesting HVAC transmitter designs.
おすすめ
Consumer Electronics Remote Controls
Battery-powered remote controls benefit from the PIC16LF1615T-I/JQ XLP architecture, which keeps standby current in the nA range and supports months or years of operation from a single coin cell. The 14KB Flash is sufficient to host IR protocols (RC5, NEC, SIRC) or simple RF encoders, while the 10-bit ADC reads battery voltage for low-battery detection. The 16-pin UQFN (4x4mm) fits behind small rubber keypads in slim remote enclosures. Use this MCU together with an IR LED driver transistor and a 32.768 kHz crystal for RTC-style timekeeping on remote timers.

設計ノート
The PIC16LF1615T-I/JQ ships in a 16-pin UQFN package with a center exposed pad (EP) that must be soldered to a continuous ground pour on the top or bottom PCB layer for thermal dissipation and electrical reference. Stencil design should use a single large aperture for the EP rather than multiple small ones to ensure consistent solder voiding below 25%. Keep the EP ground pour isolated from noisy return currents such as motor driver returns or TRIAC commutation loops to avoid injecting noise into the MCU ground reference.
Decouple VDD with a 100nF ceramic capacitor placed within 3mm of the VDD pin and a 1uF to 10uF bulk capacitor. Per Microchip's PIC16F161X datasheet, do NOT place large capacitors (>1nF) directly on PGC/PGD lines because they interfere with ICSP programming and in-circuit debugging. The XLP sleep current of the LF variant is in the nA range, so choose an LDO or battery chemistry that does not introduce higher quiescent current than the MCU itself.
When migrating from PIC16LF1615T-I/JQ to PIC16F1615T-I/JQ (F variant), verify that your design can accept the wider 2.3V-5.5V supply range - the LF variant's 1.8V minimum is intentional for single-cell Li-ion operation. Also confirm the ZCD peripheral pin assignment because some PIC16F161X derivatives place ZCD on different I/O pins. Always re-validate the configuration bits after a derivative change because the configuration-word addresses and defaults differ across the family.
If the design uses the ICSP/ICD pins (RA0/RA1) for in-circuit programming, add a 4.7k pull-up on MCLR and route the PGC/PGD traces short and direct. Microchip recommends no series resistors on PGC/PGD for reliable programming, but if signal integrity demands them keep the value below 100 ohm. Always include a header or test-pad footprint for the ICSP connector so field firmware updates are possible without board rework.
コンプライアンス情報
