PIC16F1829T-I/SS 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on a single IC. The PIC16F1829 belongs to Microchip's PIC16 enhanced mid-range family (PIC16 -> 8-bit microcontroller -> embedded MCU -> semiconductor), targeting battery-powered and energy-harvesting products where active current, sleep current, and peripheral integration directly determine battery life.
Key features include 32MHz maximum CPU speed (8 MIPS), 256 bytes of EEPROM data memory, 17 digital I/O pins, 2 comparators, 2 PWM modules, and support for UART, SPI, I2C, and LIN serial interfaces. The XLP sleep current is rated in the nanoampere range, enabling multi-year coin-cell operation in sensor applications.
The device uses Microchip's enhanced mid-range 16-bit instruction set architecture with a 14-bit instruction word and a single-cycle hardware stack. The integrated 32MHz high-speed oscillator eliminates the need for an external crystal in many designs, reducing BOM cost and PCB area while improving EMI and mechanical robustness.
Typical applications include capacitive touch key pads, battery-powered sensor nodes, LIN slave nodes in automotive body electronics, low-cost consumer appliances, and general-purpose 5V/3.3V embedded control. The wide 2.5V-5.5V supply range supports both 3.3V and 5V rails without level shifters.
When designing with this part, choose between internal oscillator accuracy modes: the High-Frequency Oscillator (HFINTOSC) is factory calibrated to ±1% typical, while the Low-Frequency Oscillator (LFINTOSC) is used for lowest-power sleep wake-up. Decouple VDD with at least one 100nF ceramic capacitor close to the pin pair.
This page synthesizes distributor pricing, drop-in alternatives drawn from the same PIC16F1829 die family, and practical design notes not found in the standalone manufacturer datasheet, giving engineers a one-stop BOM and design reference.

일반적인 애플리케이션
PIC16F1829T-I/SS 적합 용도: 6 애플리케이션s: Capacitive Touch Keypad Controller, LIN Slave Node in Automotive Body Electronics, Battery-Powered Wireless Sensor Node, Small Appliance and Consumer Control, Industrial Process Sensor Transmitter, General-Purpose 5V/3.3V Embedded Control Board.
Capacitive Touch Keypad Controller
The PIC16F1829T-I/SS is purpose-built for capacitive touch interfaces thanks to its integrated mTouch peripheral, which supports up to 12 touch channels without an external touch IC. The 32 MHz CPU executes Microchip's CTMU and mTouch libraries with sub-millisecond response, while 17 I/O pins directly drive the touch sensors and feedback LEDs. XLP sleep current in the nanoampere range allows battery-powered remote controls to last multiple years on coin cells. Place 100 nF decoupling at each VDD/VSS pin pair and route touch traces with guard rings to suppress EMI.

LIN Slave Node in Automotive Body Electronics
The PIC16F1829T-I/SS supports the LIN (Local Interconnect Network) bus natively through its enhanced USART and a dedicated LIN protocol handler, allowing integration as a LIN 2.x slave node for door modules, seat controllers, mirror adjusters, and ambient lighting. With 14 KB Flash, developers can run both the LIN stack and the body-electronics firmware in a single chip, reducing BOM cost versus discrete transceivers. The 2.5-5.5 V supply range aligns with the 12 V battery rail after LDO regulation, and the SSOP-20 footprint is easy to hand-rework in service environments.

Battery-Powered Wireless Sensor Node
With XLP (eXtreme Low Power) technology and a nanoampere sleep current, the PIC16F1829T-I/SS can run for multiple years on a single CR2032 coin cell when waking periodically to sample sensors. The integrated 12-channel 10-bit ADC connects directly to temperature, light, and humidity sensors without an external amplifier, and the 32 MHz HFINTOSC eliminates the need for an external crystal. Combined with UART/SPI/I2C interfaces for an attached radio module, the MCU provides a compact BOM for IoT end-nodes in home automation and industrial monitoring.
추천
Small Appliance and Consumer Control
The PIC16F1829T-I/SS is well-suited to small home appliances such as coffee makers, blenders, kitchen timers, and fan controllers where its 32 MHz CPU, 14 KB Flash, and 17 I/O provide ample headroom for PWM motor control, LED driving, and HMI scan routines. The 2.5-5.5 V supply range accepts both 3.3 V and 5 V rails, simplifying integration with USB-powered designs or legacy 5 V interfaces. The SSOP-20 footprint supports compact PCB layouts, and the integrated ECCP PWM modules deliver accurate motor speed control without external driver ICs in low-power appliance designs.

Industrial Process Sensor Transmitter
In a 4-20 mA loop-powered or 24 V industrial sensor transmitter, the PIC16F1829T-I/SS provides a robust 8-bit processing platform with industrial-temperature-grade reliability (-40 C to +85 C). Its 12-channel 10-bit ADC is sufficient for bridge sensors, RTDs, and 0-10 V analog inputs, while the 256-byte EEPROM stores calibration coefficients and serial numbers for traceability. The UART/SPI/I2C peripherals support HART, Modbus RTU, or proprietary field-bus interfaces via external transceivers, and the SSOP-20 package withstands the mechanical stress of vibration-heavy industrial environments.
추천
General-Purpose 5V/3.3V Embedded Control Board
The PIC16F1829T-I/SS serves as a flexible general-purpose MCU for educational kits, hobby robotics, and prototype embedded control boards thanks to its broad peripheral set and free Microchip MPLAB X IDE / XC8 toolchain. The 14 KB Flash holds modest application firmware while 1 KB SRAM supports stack and heap, and the 32 MHz internal oscillator removes external crystal cost and EMI concerns. The SSOP-20 package is breadboard-friendly with a breakout adapter, and the integrated ICSP programming interface allows direct firmware loading via PICkit 3 or PICkit 4 programmers.

설계 노트
Place a 100 nF X7R ceramic decoupling capacitor within 3 mm of the VDD pin (pin 18) and a bulk 1-10 uF capacitor at the PCB power entry. For battery applications using XLP sleep, ensure the ICSP programmer is disconnected after programming; an active ICSP pull-up on MCLR/RA3 can leak several hundred microamps and drain a coin cell in days. Use the LFINTOSC for wake-up timing in sleep modes to minimize HFINTOSC startup surge.
Do not drive MCLR/RA3 (pin 1) as a general output only; it doubles as the master-clear reset and must not be held low at power-up or the MCU will be held in reset. Configure CONFIG words in MPLAB X to disable MCLR if RA3 is needed as a regular I/O. Also, ensure ICD communication lines (ICSPDAT/ICSPCLK on RA0/RA1) are not loaded with external capacitance exceeding the ICSP specification, otherwise in-circuit debugging will fail intermittently.
Route the 32 kHz LFINTOSC crystal traces (if used) as short, guarded pairs away from switching nodes. For SSOP-20 layout, use a continuous ground plane beneath the IC and stitch vias around the perimeter to reduce radiated emissions. Touch-sensor traces should be 0.2-0.5 mm wide with a 5 mm ground guard ring on the same copper layer; avoid 90-degree bends and keep via stubs off the sensor pads.
Estimated: at 32 MHz CPU and 5 V supply driving one LED on each I/O at 10 mA, total ground-bounce rise time is approximately 1.5 ns; route the high-current LED returns directly to the VSS pin (pin 12) rather than through the ground plane to minimize digital noise coupling into the ADC inputs. Keep analog signals on RA0-RA2 separated from PWM outputs on RC1-RC2 by at least 5 mm or a ground trace.
When using the USART at 115.2 kbps or higher, place a series resistor (22-100 ohm) at the TX pin to dampen reflections on long cable runs. For LIN bus applications, add a 1 nF capacitor on the LIN TX/RX pin to filter automotive RF noise. Ensure the LIN transceiver (e.g., MCP2003 or TJA1027) is placed within 50 mm of the MCU to keep parasitic capacitance low and avoid bus errors during EMC testing.
규정 준수 정보
RoHS compliant per Microchip product page and datasheet. Halogen-Free compliant per datasheets.com listing.
