PIC16F1829-E/SO Übersicht
An 8-bit PIC microcontroller is a RISC-based single-chip computer that integrates a CPU core, Flash program memory, SRAM, EEPROM, peripherals, and I/O on a single die. Within the broader taxonomy, the PIC16F1829 belongs to the PIC16F family of enhanced mid-range cores, which itself sits under 8-bit microcontrollers, then microcontrollers (MCU) and finally semiconductor integrated circuits. Microchip's nanoWatt XLP (eXtreme Low Power) technology further extends battery life in portable applications where quiescent current dominates energy budgets.
Key features of the PIC16F1829 include 18 digital I/O pins, 12 channels of 10-bit ADC, two 8-bit and one 16-bit timers, enhanced PWM with up to four outputs, two comparators, an EUSART, two MSSP (I2C/SPI) modules, and a 32 MHz internal oscillator. The device also integrates mTouch capacitive touch sensing hardware and a data signal modulator for waveform generation, making it well-suited to mixed-signal designs where reducing external component count is critical.
The PIC16F1829 uses a 14-bit instruction width with a 49-instruction set, an 8-level hardware stack, and an internal 32 MHz oscillator that eliminates the need for an external crystal in most designs. The device supports both In-Circuit Serial Programming (ICSP) and low-voltage programming for flexible firmware updates in production and field-service scenarios.
Typical applications include consumer appliances, sensor nodes, LED lighting controllers, battery-powered IoT devices, low-cost motor control, and industrial control modules. Its combination of XLP standby currents below 100 nA and rich peripheral set makes it a strong fit for energy-harvesting and remote-control products.
When designing with this device, ensure the VDD decoupling network uses a 100 nF ceramic capacitor close to the pin and a bulk capacitor on the power rail. The MCLR pin must be pulled high through a 10 kohm resistor for normal operation, or tied directly to VDD if the reset function is unused.

Typische Anwendungen
PIC16F1829-E/SO ist geeignet für 8 Anwendungs: Consumer Appliance Control Board, Battery-Powered IoT Sensor Node, LED Lighting Controller, Industrial Sensor Module, Low-Cost BLDC / Brushed Motor Control, Capacitive Touch User Interface, Remote Control / Wireless Key Fob, Energy Harvesting Sensor Node.
Consumer Appliance Control Board
The PIC16F1829-E/SO fits consumer appliance control boards where it acts as the main MCU for sensor read-out, user-interface scanning, and motor/relay actuation. Its 14 KB Flash supports state-machine plus display logic for washers, microwave ovens, or air conditioners without external memory. The 12-channel 10-bit ADC handles NTC temperature inputs, water-level probes, and current sensing; the EUSART links to an inverter or display board. With -40C to +125C and nanoWatt XLP standby below 100 nA, it survives hot enclosures and meets EU standby regulations under 1 W. Connect user buttons to mTouch pins to eliminate mechanical switches, reducing BOM cost. A typical design adds a 100 nF bypass on VDD, a 10 kohm MCLR pull-up, and ICSP header for in-field firmware updates.

Battery-Powered IoT Sensor Node
The PIC16F1829-E/SO is a strong MCU for battery-powered IoT sensor nodes where current draw dominates battery life. nanoWatt XLP sleep below 100 nA lets a 2x AA alkaline pack run multi-year deployments with hourly wake-ups. Its two MSSP peripherals support I2C sensors (temperature, humidity, accelerometer) plus SPI connections to a sub-GHz transceiver. The internal 32 MHz oscillator avoids external crystals, cutting BOM cost on disposable nodes. The PIC16F1829-E/SO mTouch input can replace a mechanical wake button on door/window sensor products. Pair the MCU with a digital temperature sensor on one MSSP and a low-power RF module on the second MSSP for an end-to-end wireless sensor that fits on a 30 x 30 mm coin-cell board.
Empfohlen
LED Lighting Controller
The PIC16F1829-E/SO serves well as an LED lighting controller for both constant-current drivers and addressable RGB strips. Its enhanced PWM module with up to 4 outputs can drive MOSFETs for analog dimming, while mTouch inputs detect capacitive touch pads on track lighting or under-cabinet fixtures. The 12-channel ADC monitors LED forward voltage and supply current for thermal-foldback protection, critical for high-power downlights where Tj of the LED must be limited. Designers can implement DMX-512 or DALI receive over the EUSART without external protocol ICs. The XLP sleep mode enables standby under 0.5 W to comply with EU 1194/2012 standby regulations while supporting capacitive on/off control on the fixture.
Empfohlen
Industrial Sensor Module
The PIC16F1829-E/SO's -40C to +125C operating range makes it suitable for industrial sensor modules that mount near motors, drives, or outdoor enclosures. The 12-bit ADC equivalent - actually 10-bit - combined with two op-amp-style comparators handles 4-20 mA current loop signal conditioning for pressure, flow, or level transmitters. Modbus RTU slave protocol on the EUSART allows integration into PLC and SCADA systems without an external transceiver IC. nanoWatt XLP sleep lets battery or energy-harvested transmitters operate for years on a single D-cell. Add an external CAN transceiver if longer industrial busses are needed; otherwise the EUSART plus RS-485 driver suffices for plant networks.
Empfohlen
Low-Cost BLDC / Brushed Motor Control
The PIC16F1829-E/SO can act as the controller for low-cost brushed DC or small BLDC motors used in fans, pumps, and small appliances. Its 16-bit timer drives PWM at 20 kHz to keep switching noise above the audible band, and the integrated comparators implement hardware over-current protection that latches the PWM output within microseconds of a fault. Designers implement field-oriented control - FOC - in software on this 8-bit core for sub-100 W motors where the 8 MIPS instruction throughput is sufficient. For battery-powered tools, the EUSART reports telemetry back to a host controller while the MCU handles the real-time commutation loop independently.
Empfohlen
Capacitive Touch User Interface
The PIC16F1829-E/SO integrates Microchip's mTouch capacitive touch sensing hardware, eliminating external touch ICs and reducing BOM cost in user-interface panels for appliances, IoT, and lighting. Up to 18 mTouch-capable pins support buttons, sliders, and proximity wake-up from sleep - the latter critical for battery-powered devices that must respond to a hand wave without continuous scanning. The hardware mTouch module is implemented using the on-chip CPS (Capacitive Sensing) module, reducing firmware overhead and ensuring deterministic response under 50 ms. Combined with XLP sleep below 100 nA, a wake-on-touch button can run for years on a CR2032 coin cell.
Empfohlen
Remote Control / Wireless Key Fob
The PIC16F1829-E/SO suits wireless key fobs and remote controls where standby current is dominated by the MCU. nanoWatt XLP sleep below 100 nA extends coin-cell life to multi-year horizons typical of TV remotes and garage openers. The internal 32 MHz oscillator allows the MCU to wake, transmit via a low-cost SAW-based or sub-GHz module, and return to sleep within milliseconds. mTouch pins replace mechanical buttons for sealed, waterproof designs. The MCU's 14 KB Flash is generous for multi-protocol firmware (RF4CE, BLE-beacon, proprietary), and ICSP allows in-field firmware updates for end-of-line reflash.
Empfohlen
Energy Harvesting Sensor Node
The PIC16F1829-E/SO is well-suited to energy-harvesting sensor nodes because of its nanoWatt XLP technology and very low sleep current. The MCU can wake from sleep on an external interrupt, take a sensor reading via ADC or I2C, transmit via a sub-GHz radio, and return to sleep all under 100 uA average draw. Solar, thermoelectric, or vibration harvesters can power the design without a battery or with a small supercap backup. mTouch inputs allow user interaction without additional components. Microchip's 41440A datasheet application notes provide reference firmware for sleeping, waking, and managing energy budgets on harvesting sources.

Wichtigste Unterscheidungsmerkmale
- Extended -40C to +125C operating range in SOIC-20 (vs. PIC16F1829-I/SO)
- Wide 2.5 V to 5.5 V VDD range vs LF variant (vs. PIC16LF1829-I/SO)
- nanoWatt XLP sleep current below 100 nA (vs. PIC18F27K40-E/SS)
Designhinweise
Decouple the PIC16F1829-E/SO VDD pin with a 100 nF ceramic capacitor placed within 5 mm of the pin and a bulk capacitor (e.g. 10 uF) on the supply rail. For SOIC-20 boards, place the bulk capacitor near pin 6 (VDD) and the high-frequency bypass near the same pin to suppress switching noise from the internal oscillator. Use a 10 kohm pull-up on MCLR (pin 4) tied to VDD; if MCLR is unused, route it directly to VDD with no capacitor, since C in parallel with the internal pull-up slows the reset rise time.
Estimated: At 32 MHz and -E grade +125 C junction, IO sink current of 25 mA per pin can exceed the package's 200 mA total dissipation limit. De-rate pin current to 12-15 mA in LED matrix or relay-driver designs and ensure only one pin drives large loads. The -E grade SOIC-20 is rated for a maximum junction temperature of +150 C; if you are near this limit, force RC clock prescaler or duty-cycle the heavy loads via PWM to keep Tj under +125 C in enclosed housings.
When using the MSSP peripherals in SPI mode at the maximum 32 MHz CPU clock, keep traces between the PIC16F1829-E/SO and the slave device under 50 mm and use a 4.7 kohm pull-up on the SCK line to damp reflections. For I2C at 400 kHz Fast-mode, place 4.7 kohm pull-ups on SDA and SCL close to the MCU. Use the MSSP interrupt flags rather than busy-wait loops to avoid CPU stalls that disrupt baud-rate generation on the EUSART.
