PIC16F886T-I/ML 概要
A PIC® microcontroller (Programmable Interface Controller) is a Harvard-architecture RISC-based 8-bit MCU family from Microchip Technology. The PIC16F886 sits in the PIC16F88x mid-range sub-family, sitting hierarchically between the entry-level PIC10/12/16 baseline parts and the high-performance PIC18/dsPIC families. Its 14-bit instruction word and 35-instruction RISC core deliver deterministic interrupt latency and very low active/standby current draw (microchip's nanoWatt technology), making the family widely used in cost-sensitive embedded designs.
Key features of the PIC16F886 include 25 digital I/O pins, an internal 8 MHz and 31 kHz oscillator, in-circuit serial programming (ICSP) and in-circuit debugger (ICD) support, self-programming of Flash, a 10-bit ADC with up to 11 channels, hardware USART/MSSP and a wide 2.0V to 5.5V supply range. The mid-range 14-bit instruction set and nanoWatt sleep modes (typical < 1 uA standby) make it ideal for battery-powered and always-on applications.
Typical applications for the PIC16F886T-I/ML include industrial control nodes, sensor signal conditioning, low-cost motor drive (small DC fans and brushed motors via ECCP PWM), LED lighting controllers, automotive body electronics and consumer white-goods user interfaces. Its small 6x6 mm QFN footprint suits space-constrained PCBAs and the exposed thermal pad (EP) lowers theta-JA for higher-power dissipation in sealed enclosures.
When designing with this device, observe the absolute maximum VDD of 5.5V and use a 0.1 uF decoupling capacitor within 5 mm of each VDD/VDDIO pin pair. The 28-QFN exposed pad must be soldered to a properly sized copper pour to meet the 41 C/W theta-JA thermal rating. For new designs, prefer the PIC16F886-I/ML (tray) variant for prototype builds, and reserve the T-suffix part for high-volume assembly lines.

主な用途
PIC16F886T-I/ML の用途: 6 件s: Industrial Sensor Node, Small DC Motor / Fan Controller, LED Lighting Controller, Consumer White-Goods User Interface, Automotive Body Electronics (Non-Safety), Battery-Powered IoT Edge Sensor.
Industrial Sensor Node
The PIC16F886T-I/ML fits industrial sensor nodes because its 14 KB Flash accommodates full Modbus RTU or CANopen protocol stacks plus sensor calibration routines, while the 10-bit ADC with 11 channels handles thermocouple, 4-20 mA and 0-10 V transducer inputs directly. The wide 2.0V-5.5V supply range and industrial -40C to +85C grade suit 24V-powered PLC backplanes and outdoor field instruments. nanoWatt sleep current below 1 uA enables battery-backed nodes with multi-year life.
おすすめ
Small DC Motor / Fan Controller
The PIC16F886T-I/ML is well suited for small brushed DC motor and fan speed controllers because its Enhanced CCP (ECCP) module provides hardware PWM with complementary outputs, programmable dead-band and fault shutdown - all critical for half-bridge and full-bridge motor drive. The 20 MHz CPU speed gives 200 ns PWM resolution, sufficient for smooth low-speed torque control. The 25 I/O pins handle tachometer input, current sense and direction logic.
おすすめ
LED Lighting Controller
The PIC16F886T-I/ML is a natural fit for LED lighting controllers because its ECCP + CCP modules provide up to four PWM channels for RGBW dimming with 10-bit brightness resolution (1024 steps per LED). The 14 KB Flash supports DMX512, DALI or 0-10 V dimming protocol stacks, and the 256 bytes EEPROM stores calibration and address data over the lifetime of the luminaire. Operating from 2.0V-5.5V it runs from common 3.3V or 5V LED-driver auxiliary rails.
おすすめ
Consumer White-Goods User Interface
The PIC16F886T-I/ML fits consumer appliance user-interface modules because its 14 KB Flash easily holds capacitive-touch, button-matrix and 7-segment/multiplexed LCD driving routines, plus EEPROM-backed user settings. The 25 I/O pins drive keypads, rotary encoders and LED indicators without external logic. Industrial-grade silicon and -40C to +85C range ensure reliability in cold garages, hot kitchens and unheated laundry rooms.
おすすめ
Automotive Body Electronics (Non-Safety)
The PIC16F886T-I/ML works in automotive body-electronics applications such as seat controllers, mirror adjusters, HVAC panel controls and lighting modules because the industrial -40C to +85C variant tolerates cabin temperatures and the LIN-compatible EUSART plus MSSP interfaces connect to LIN/CAN bus ICs. For under-hood or safety-critical applications, prefer Microchip's AEC-Q100-qualified PIC16F variants; this standard part is intended for cabin body modules only.
おすすめ
Battery-Powered IoT Edge Sensor
The PIC16F886T-I/ML fits battery-powered IoT edge sensors because the nanoWatt technology delivers <1 uA standby current, allowing multi-year coin-cell operation with periodic wake-and-transmit duty cycles. The 14 KB Flash supports over-the-air bootloaders via the EUSART or MSSP, and the 368 bytes RAM holds one conversion buffer. The 2.0V-5.5V supply range accepts LiSOCl2, alkaline and Li-ion chemistries without boost conversion.

設計ノート
Place a 0.1 uF decoupling capacitor within 5 mm of each VDD pin pair and a 10 uF bulk capacitor at the regulator output. According to Microchip's PIC16F886 datasheet (DS41299), the BOR (brown-out reset) is enabled by configuration bit; leaving it enabled prevents code corruption when batteries droop. Average active current at 20 MHz and 5 V is approximately 5 mA; nanoWatt sleep current drops to under 1 uA with the internal LF oscillator running.
The 28-QFN (6x6 mm) exposed pad must be soldered to a ground copper pour of at least 1 sq inch to achieve the datasheet 41 C/W theta-JA rating. Estimated: at 5 V VDD and 5 mA active current, die dissipation is 25 mW - well below the 100 mW QFN limit - so thermal management is rarely an issue at room temperature. In sealed enclosures with no airflow, derate maximum ambient by 10 C to stay below the 125 C junction max.
Route the ICSP/ICD lines (RB6/PGC and RB7/PGD) as short as possible and avoid stubs - the Microchip ICD programmer sources current on these pins. According to Microchip's ICSP application notes, place the ICD connector at the PCB edge with ESD protection. Route analog inputs (RA0-RA5, RB0-RB5) away from PWM outputs (RC1/RC2) and clock signals to minimize ADC crosstalk. Add a 100 nF capacitor close to the VREF pin if the ADC reference is used externally.
Do not connect unused I/O pins directly to VDD - the datasheet specifies floating pins or weak pull-ups via software to minimize leakage. MCLR (pin 3) requires a 10 kohm pull-up if not driven by the ICD; tying it directly to VDD prevents reset. The LFINTOSC is calibrated to +/-1% from factory but drifts +/-5% over temperature - budget accordingly for UART baud-rate accuracy at extreme temperatures. According to the datasheet, the ADC requires acquisition time of at least 1.4 us for 10-bit accuracy; using shorter wait causes systematic gain error.
