PIC16F1829LINT-I/SS Overview
An 8-bit microcontroller (MCU) is a single-chip computer optimized for embedded control tasks. The PIC16F1829 belongs to Microchip's enhanced mid-range core (PIC16) family, which sits hierarchically above baseline PIC10/12 devices and below the PIC18 and PIC24 families. It combines a RISC-like Harvard architecture CPU with on-chip peripherals, non-volatile program memory, and rich serial interfaces in a small footprint. XLP™ (eXtreme Low Power) technology adds sleep currents below 50 nA typical, making it ideal for battery-powered and always-on applications.
Key features include the LIN/J2602 protocol engine for in-vehicle networking, the mTouch™ capacitive sensing peripheral, 17 I/O pins with interrupt-on-change, and 4 timers (Timer0/1/2 plus SMT). The integrated 32MHz internal oscillator eliminates an external crystal in many designs, while an on-chip temperature indicator supports basic thermal monitoring without external sensors.
The device is built on Microchip's enhanced mid-range 14-bit instruction set, which provides single-cycle execution on most opcodes and C-friendly orthogonal addressing. The CIP (Core Independent Peripherals) approach lets hardware handle tasks like waveform generation, signal measurement, and LIN framing autonomously, freeing the CPU to remain asleep and reducing average power.
Typical applications include LIN bus nodes in automotive body electronics, capacitive touch user interfaces, sensor conditioning, low-power wireless sensor nodes, and industrial control replacement of legacy 8-bit designs. The wide 1.8V–5.5V range also supports direct operation from 2-cell AA or single Li-ion chemistries.
When designing with this part, choose the SSOP-20 footprint carefully: the LINT suffix indicates LIN/J2602 hardware support, not generic USART-only operation. Plan for proper LIN bus termination and ESD protection, and budget clock cycles for the LIN state machine in real-time scheduling.

Typical Applications
PIC16F1829LINT-I/SS is suitable for 6 applications: Automotive LIN Bus Node, Capacitive Touch User Interface, Battery-Powered Sensor Node, Industrial Control Replacement, Consumer Appliance Control, HVAC Damper/Valve Actuator.
Automotive LIN Bus Node
The PIC16F1829LINT-I/SS is purpose-built for LIN/J2602 nodes in automotive body electronics such as door modules, mirror controllers, seat adjusters, and HVAC flap motors. Its integrated LIN hardware engine handles break, sync byte, and PID auto-baud detection autonomously, freeing the CPU to remain in XLP sleep mode between bus events - typical LIN quiescent current stays below 50 µA. The 32 MHz internal oscillator meets LIN timing accuracy (≤±1.5%) without an external crystal, and the 14 KB flash comfortably fits the LIN 2.x stack plus application logic. Pair with an MCP2021A LIN transceiver for a complete 12V bus node.
Recommended
Capacitive Touch User Interface
The mTouch™ capacitive sensing peripheral in the PIC16F1829LINT-I/SS enables robust button, slider, and wheel interfaces for white goods, IoT panels, and industrial HMI front panels. With XLP™ sleep currents under 50 nA, an 8-button keypad can be polled every 50 ms at <2 µA average draw, supporting multi-year coin-cell operation. The 1 KB RAM handles mTouch library state plus user code, while 17 I/O pins provide ample headroom for LEDs and segment displays. Spread-spectrum clocking on the internal oscillator improves EMC immunity in touch applications.
Recommended
Battery-Powered Sensor Node
XLP™ technology combined with the 1.8V minimum supply makes the PIC16F1829LINT-I/SS ideal for battery-powered wireless sensor nodes on 2x AA alkaline or single-cell Li-ion chemistries. Sleep currents below 50 nA extend shelf life, while the 32 MHz internal oscillator eliminates standby crystal current. The 9-channel 10-bit ADC reads thermistors, photodiodes, or MEMS sensors; the on-chip temperature indicator provides basic cold-junction compensation without extra parts. Average draw for a once-per-second wake-and-transmit node is under 5 µA, projecting 5+ years from 2x AA cells.
Recommended
Industrial Control Replacement
Engineers modernizing legacy 8-bit industrial controllers benefit from the PIC16F1829LINT-I/SS's 14 KB flash (vs 2-4 KB on legacy PIC16F84/PIC16F628 designs), C-friendly instruction set, and modern peripherals like the SMT (Signal Measurement Timer). The 5.5V maximum VDD allows direct drive of 5V logic relays and optocouplers, and the 17 I/O pins serve as PWM outputs, encoder inputs, and serial links to a master PLC. Drop-in SSOP-20 footprint enables form-fit upgrades to existing PCBs while doubling flash capacity for richer diagnostic stacks.
Recommended
Consumer Appliance Control
From coffee machines to robotic vacuum chargers, the PIC16F1829LINT-I/SS delivers enough flash and peripherals for product-feature firmware in appliance-class BOMs. The mTouch™ peripheral handles sleek glass-front button interfaces without mechanical switches; the UART/SPI/I2C ports drive segment LCDs, motor drivers, and Wi-Fi co-processors. Operating directly from rectified 5V or USB rails simplifies power tree design, while SSOP-20 hand-solders cleanly for prototype and small-batch runs typical of premium appliances.
Recommended
HVAC Damper/Valve Actuator
Low-power 24V damper and valve actuators in HVAC systems benefit from the PIC16F1829LINT-I/SS's wide 1.8V–5.5V supply and LIN/J2602 engine for building-automation buses. Multiple PWM channels and the SMT timer support closed-loop feedback on a stepper or DC motor; the 9-channel ADC reads position, temperature, and current sense signals. Deep-sleep XLP modes preserve battery backup during power-loss events, while the 32 MHz core handles modulation and communication without performance bottlenecks.

Key Differentiators
- Integrated LIN/J2602 hardware engine (vs PIC16F1829-I/SS)
- 14 KB flash vs 7 KB on smaller sibling (vs PIC16F1828-I/SS)
- Extended temperature range option in same pinout (vs PIC16F1829-E/SS)
Design Notes
Estimated: at VDD=3.3V with the internal 32 MHz oscillator running and CPU active, the PIC16F1829LINT-I/SS draws ~4 mA typical. In XLP sleep mode, the data sheet specifies <50 nA at 1.8V with watchdog disabled - perfect for battery-backed sensor nodes. Place a 100 nF ceramic decoupling cap within 5 mm of VDD (pin 1) and a 10 µF bulk cap on the supply rail. For LIN bus nodes powered from 12V, add an MCP1790 30V LDO upstream with its own input bulk of 1 µF minimum.
The 20-SSOP footprint has 0.65 mm pin pitch - use NSMD pads with 0.4 mm width and a stencil aperture of 0.3 mm x 1.0 mm for reliable paste release. Route VDD and VSS as wide traces (≥0.3 mm) and place the decoupling cap on the same side as the MCU, never under the package body. Keep crystal traces (RA6/OSC2, RA7/OSC1) short and symmetric, and surround them with a ground guard ring to suppress radiated emissions into the LIN bus.
When the PIC16F1829LINT-I/SS drives a LIN bus through an external MCP2021A transceiver, ensure the master-side termination is a 1 kΩ resistor in series with the LIN diode and a 30 pF cap to ground (per LIN 2.x conformance). The MCU's LIN engine expects a recessive-high/idle condition and a dominant-low driven state; never tie the LIN pin directly to VDD without the transceiver's protection. For noise-sensitive designs, enable the data CRC checksum feature and configure the LIN state machine interrupt before enabling TX.
Estimated: do not use PIC16F1829-I/SS firmware on a PIC16F1829LINT-I/SS without reinitializing the LIN peripheral - the LIN-specific registers (LINCON, BCON) are absent on non-LINT parts, so the reverse migration silently fails. Also avoid setting FOSC to external crystal mode unless a 32.768 kHz or 20 MHz crystal is present; the 32 MHz internal oscillator is factory-calibrated to ±1% at room temperature and ±2% over industrial range, suitable for LIN 2.x timing. Finally, reserve pin 4 (RA3/MCLR) as a reset input by default - configure it as an I/O only if MCLR is disabled in configuration bits.
Compliance Information
Microchip product environmental compliance reports RoHS and REACH compliance with lead-free matte-tin plating. Not AEC-Q100 qualified; automotive LIN nodes typically use the bare PIC16F1829LINT silicon tested per OEM-specific requirements rather than formal AEC-Q100.
