PIC16F882-I/SO Übersicht
An 8-bit microcontroller (MCU) is a single-chip processor integrating CPU, RAM, non-volatile program memory, and peripherals (timers, ADC, communication modules) into one package. PIC microcontrollers occupy the broader category microcontrollers -> microcomputer -> embedded processor -> semiconductor. They are widely used as the central controller in cost-sensitive embedded designs where deterministic instruction execution and low power matter more than raw processing throughput, and they typically out-perform discrete logic solutions in flexibility and BOM density.
Key features of this part include a 10-bit ADC with up to 11 input channels, two 8-bit timers plus one 16-bit timer, Capture/Compare/PWM (CCP) modules, an Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART), Master Synchronous Serial Port (MSSP) for SPI/I2C, two analog comparators, and a wide operating voltage range of 2.0 V to 5.5 V. The internal 8 MHz and 31 kHz oscillators, 16-level watchdog timer, and self-programming support simplify single-chip designs and field firmware upgrades.
The PIC16F882 uses a Harvard-architecture RISC core with separate program and data buses, plus integrated debug via In-Circuit Debugger (ICD). NanoWatt Technology provides dynamic power-saving modes (idle, sleep with WDT, etc.). Brown-out Reset (BOR), Power-on Reset (POR), and configurable code protection harden designs against supply transients and firmware theft.
Typical applications include industrial control panels, appliance control boards, automotive body and interior subsystems, low-end sensor hubs, LED lighting controllers, battery chargers, remote controls, and small consumer products. The combination of EEPROM data storage and self-programming makes the part suitable for field-upgradeable firmware with non-volatile parameter retention.
When designing with this device, ensure decoupling (100 nF + bulk) is placed within 5 mm of VDD, and respect the 25 mA per I/O pin sink/source limit. Use Microchip's MPLAB XC8 toolchain and pickit debugger ecosystem for code development; the ICD pins (RB6/RB7) require no external components for debug. Pin assignment must keep RA pins analog-capable inputs for ADC use.

Typische Anwendungen
PIC16F882-I/SO ist geeignet für 6 Anwendungs: Industrial Control Panels, Appliance Control Boards, Automotive Body and Interior Modules, Remote Control and Sensor Nodes, Battery Chargers and Smart Power, LED Lighting Controllers.
Industrial Control Panels
The PIC16F882-I/SO's 5 MIPS throughput at 20 MHz, 11-channel 10-bit ADC, and EUSART fit industrial panel applications such as HMI controllers, machine status indicators, and low-rate process loops. The -40C to +85C industrial temp grade handles factory-floor thermal swings, and 128 bytes EEPROM retain set-point values across power cycles. The 25 I/O pins with 25 mA drive directly sink LED indicators and pull small relays without external buffers. The PIC's deterministic instruction set simplifies real-time logic for safety interlocks; the MSSP peripherals talk to I2C sensors and SPI LED drivers for a fully integrated panel controller.
Empfohlen
Appliance Control Boards
The PIC16F882-I/SO is a strong match for major-appliance controller boards (washing machines, dishwashers, microwave ovens) where 8-bit PIC determinism, 2.0 V to 5.5 V supply tolerance, and integrated peripherals (CCP for motor PWM, EUSART for display communication, ADC for sensing) reduce BOM. Brown-out Reset prevents corruption under noisy ac-rectified rails. The 128-byte EEPROM stores user presets (temperature, mode, timer) without external non-volatile memory. The 28-SOIC footprint has 1.27 mm pin pitch, supporting robust through-hole or surface-mount assembly lines common to home appliance manufacturing.
Empfohlen
Automotive Body and Interior Modules
The PIC16F882-I/SO fits interior lighting, seat-position controllers, HVAC blend actuators, and small accessory modules where cost efficiency outweighs high compute demands. The 10-bit ADC reads thermistor or potentiometer inputs, and the 8-bit timers drive PWM outputs for LED dimming or small motor control. Use the PIC16F882-E/SO variant for underhood or engine-bay temperatures (-40C to +125C); the I-grade variant suits cabin and seat-mounted modules. NanoWatt Technology sleep modes consume microamps in standby, extending battery life when doors or hoods rest unoccupied. AES-resistant PIC instruction set resists tampering for automotive anti-theft peripheral use.
Empfohlen
Remote Control and Sensor Nodes
Battery-powered remote controls, sensor nodes, and RF base stations fit the PIC16F882-I/SO footprint. The 2.0 V minimum supply lets a 2x AA/AAA battery stack power the device without boost converters down to a low-battery cutoff. NanoWatt sleep mode (current measured in microamps) is ideal for quiescent-dominant designs such as PIR-triggered alarm panels or remote-controlled ceiling fans. The MSSP peripheral talks to 2.4 GHz transceivers (nRF24L01, CC2500) over SPI, while the internal 8 MHz oscillator removes the need for an external crystal in less-timing-sensitive nodes. With EUSART the same chip drives legacy 433 MHz transmitter modules or RS-485 sensor buses.
Empfohlen
Battery Chargers and Smart Power
The PIC16F882-I/SO drives chargers for 1- to 4-cell Li-ion packs, low-voltage DC adapters, or solar charge controllers in a 28-SOIC package. The 10-bit ADC with 11 channels monitors cell voltage, charge current, and temperature inputs; CCP modules drive MOSFET gate waveforms for synchronous buck/boost topology. EEPROM retains charging curve parameters across power cycles. The 35-instruction RISC core simplifies compiler code generation, while the 2.0 V to 5.5 V supply range operates directly from a single-cell Li-ion (3.0 V to 4.2 V) without LDO overhead, maximizing charger efficiency and minimizing BOM.
Empfohlen
LED Lighting Controllers
The PIC16F882-I/SO controls constant-current LED drivers in architectural lighting, signage, and RGB strips. The 11-channel ADC multiplexes over current-sensing shunts and thermistor inputs to track LED junction temperature, while the CCP and timer-peripheral PWM outputs drive multiple LED channels. EEPROM stores dimming curves, color presets, and scenes that survive power loss. The MSSP supports addressable LED protocols (WS2812B/SK6812 via SPI bit-bang). The wide 2.0 V to 5.5 V supply range makes the part tolerant of dimmer-derived and rectified mains inputs, with internal brown-out reset cleanly handling noisy off-state waveforms.

Wichtigste Unterscheidungsmerkmale
- Larger memory headroom with same footprint (vs. PIC16F883-I/SO)
- Better low-power sleep for battery applications (vs. Generic PIC18F)
- EEPROM-based parameter storage (vs. PIC16F72 (legacy))
- Industrial temperature grade in a robust SOIC body (vs. PIC16F882-I/SS (SSOP))
Designhinweise
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 20) and a second similar cap on the AVVDD reference pins if used. For designs operating below 4 MHz add a 10 uF bulk capacitor near the VDD pin to support sleep-to-active inrush. The brown-out reset is configurable via config bits (BORV setpoint) - leave BOR enabled for reliable startup on noisy supply rails. Estimated: with 25 mA peak I/O drive plus MCU active current at 20 MHz, target supply design supports 50 mA continuous without LDO saturation.
Do not leave the MCLR/VPP pin floating - tie through a 10 kohm pull-up to VDD even if no reset is asserted; leaving it floating causes spurious resets. When using the MCLR function, ensure the cap on MCLR is limited to <100 nF to allow correct rise time of the internal reset signal. For ICD debugging leave RB6/RB7 dedicated to debug; using them as I/O requires careful trace design. When migrating from PIC16F72 or similar older mid-range parts, verify the analog comparator output pin mapping - some legacy assignments differ on the PIC16F882 family.
Route analog input traces (AN0-AN13) away from digital switching traces by at least 3-5 mm. Keep AVDD separated from VDD at the PCB level when precision ADC readings are required (one ferrite bead + 10 uF cap on the AVDD rail is a common pattern). Place the crystal or resonator as close as possible to RA6/OSC2 and RA7/OSC1 pins. Estimated: an 11-channel ADC multiplexer settles in 1.6 us with 50 ohm source impedance at 20 MHz; keep analog source impedance below 10 kohm for best INL/DNL performance.
The PIC16F882-I/SO at 20 MHz draws approximately 8 mA active, and the SOIC package can dissipate up to 800 mW at room temperature (per Microchip datasheet thermal resistance figures). In industrial (-40C to +85C) designs the chip will rarely encounter thermal shutdown because active current is so low; however, in output-heavy designs where 25 mA per pin is sourced simultaneously across 25 pins, the cumulative current approaches 625 mA. Estimated: with all 25 I/O at 25 mA and an ambient of 25C, junction temperature rise is well under 10C thanks to the wide 28-SOIC thermal pad-free package - no heatsink needed.
