PIC18LF4410-I/PT 概要

The Microchip Technology PIC18LF4410-I/PT is an 8-bit PIC18F family microcontroller (MCU) integrating 16KB of Flash program memory, 768 bytes of SRAM, 256 bytes of EEPROM, and a 10-bit ADC, housed in a 44-pin TQFP (10x10 mm) package with industrial -40C to +85C temperature rating.

What is a PIC18F microcontroller? An 8-bit PIC microcontroller is a Harvard-architecture RISC processor from Microchip Technology that executes one instruction per clock cycle (except branches). It belongs to the broader category of microcontroller -> embedded controller -> semiconductor device, and is widely used in motor control, sensor interfacing, and low-power embedded applications thanks to nanoWatt Technology power-management features.

Key features include a 40 MHz maximum CPU clock (10 MIPS performance), 36 digital I/O pins, a 13-channel 10-bit Analog-to-Digital Converter (ADC), two Enhanced Capture/Compare/PWM (ECCP) modules, two comparators, an Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART), a Master Synchronous Serial Port (MSSP) supporting SPI and I2C, and a 4x Phase-Locked Loop (PLL) multiplier. The LF-prefixed low-voltage core operates from 2.0V to 5.5V.

Architecturally, the PIC18LF4410 uses a 16-bit instruction word with 8-bit data path and 31-level hardware stack, providing deterministic interrupt response. The 10-bit ADC delivers up to 100K samples per second with 13 input channels multiplexed across the package pins. nanoWatt Technology supports multiple idle and sleep modes (Idle, Sleep, Deep Sleep) with sub-microamp standby current.

Typical applications include industrial sensor interface modules, building automation controllers, HVAC damper and valve controls, low-power remote sensor nodes, white-goods user-interface boards, and small consumer appliance main controllers where the 36 I/O count and 16KB Flash are sufficient.

When designing with this MCU, ensure the configuration bits (CONFIG1H through CONFIG5H) are set correctly for oscillator selection (HS, XT, RC, internal oscillator with PLL), watchdog timer state, and low-voltage programming. For power-sensitive designs, leverage nanoWatt Sleep modes with peripheral disable bits; current draw in Sleep with WDT disabled drops below 100 nA.

This page synthesizes distributor pricing, package-compatible PIC18F drop-in alternatives, and practical design notes that complement, but do not replace, the manufacturer datasheet.

主な用途

PIC18LF4410-I/PT の用途: 6 件s: Industrial Sensor Interface Module, HVAC Damper / Valve Controller, Battery-Powered Remote Sensor Node, White-Goods User Interface Board, Motor Control / Small BLDC Driver, Small Consumer Appliance Main Controller.

🏭

Industrial Sensor Interface Module

The PIC18LF4410-I/PT is well suited to multi-signal industrial sensor-interface modules requiring 13 ADC channels and 36 I/O in a compact 10x10 mm TQFP. Its 16 KB Flash is enough for sensor linearization tables, while 768 bytes of SRAM holds moving-average buffers and ring buffers for UART diagnostics. Operating from 2.0-5.5V, it can be powered from a 24V-bus-derived 5V or directly from a 3.3V LDO. The 10-bit ADC at up to 100 ksps is sufficient for 4-20 mA loop sensors and thermistor bridges with proper RC filtering.

🏭

HVAC Damper / Valve Controller

The PIC18LF4410's two Enhanced CCP modules provide two independent PWM channels for proportional damper and valve actuators, while the 10-bit ADC reads 0-10V actuator position feedback. With 36 I/O, multiple triac outputs, opto-isolated digital inputs, and an RS-485 EUSART, the MCU can serve as a single-chip HVAC zone controller. The 2.0V-5.5V supply and -40C to +85C industrial grade support rooftop and basement equipment environments.

🧩

Battery-Powered Remote Sensor Node

For battery-powered sensor nodes, the PIC18LF4410-I/PT's nanoWatt technology enables Sleep currents below 100 nA with WDT disabled, while the 2.0V minimum supply allows operation down to the last drop of a 3V CR2032 cell. The internal 4x PLL drives a 40 MHz core from a 10 MHz crystal, freeing the second EUSART/MSSP for low-duty-cycle sensor readouts (e.g. SPI temperature IC) and a wake-on-interrupt GPIO from a PIR or reed switch. 16 KB Flash supports BLE/Zigbee application sub-layer code when paired with a discrete radio.

📱

White-Goods User Interface Board

Appliance front-panel user-interface boards (washing machines, dishwashers, microwave ovens) often use the PIC18LF4410 for its 36 I/O that drives 7-segment LED displays, keypads, and rotary encoders while reading NTC temperature sensors and triac-fired heater relays. The 16 KB Flash is comfortable for state-machine firmware with fault diagnostics, and the 256-byte EEPROM stores user cycle preferences and run-time counters across power cycles. The 44-TQFP allows all signals to be routed on a single-sided UI PCB.

🏭

Motor Control / Small BLDC Driver

The PIC18LF4410-I/PT can drive small brushless DC or stepper motors through its two ECCP modules, using one channel as the 6-step commutation timer and the other as a PWM speed command. The 10-bit ADC samples back-EMF or shunt current at up to 100 ksps, while the two analog comparators provide hardware over-current protection with sub-microsecond response. The 16 KB Flash accommodates sensorless start-up routines and PI speed-loop firmware in C18 or XC8.

🔧

Small Consumer Appliance Main Controller

Coffee makers, slow cookers, smart kettles, and similar small consumer appliances fit the PIC18LF4410's profile: 16 KB Flash for multi-stage cook profiles, 36 I/O for keypad, LCD, buzzer, and triac output, and an EUSART for optional WiFi/BLE module debug logging. The 256-byte EEPROM retains last-used presets, and the nanoWatt Sleep mode drops standby consumption below the 0.5 W ErP limit for plug-in appliances.

PIC18LF4410-I/PT vs PIC18LF4320-I/PT - which is better for new designs?
Choose PIC18LF4410-I/PT when your firmware needs 16KB Flash and 768 bytes SRAM; choose PIC18LF4320-I/PT for cost-down designs needing only 8KB Flash and 512 bytes SRAM. Both share the 44-pin TQFP package and 36 I/O. PIC18LF4410 is the better fit for sensor-hub or HVAC designs with moderate protocol stacks.
What is the best drop-in replacement for PIC18LF4410-I/PT?
The best drop-in replacement for PIC18LF4410-I/PT is the PIC18LF4320-I/PT (same 44-pin TQFP, same LF core, same I/O count), accepting the smaller 8KB Flash. For 100% memory parity, the PIC18F4410-I/PT shares the identical 16KB Flash footprint but requires a 4.2V-5.5V supply. Pin compatibility is 100% for both.
Can PIC18F4410 replace PIC18LF4410 in a 3.3V design?
No. The PIC18F4410 (standard F variant) operates from 4.2V to 5.5V and cannot operate reliably at 3.3V, while the PIC18LF4410 is rated 2.0V-5.5V. Replacing an LF part with the F variant in a 3.3V system risks undefined behavior or Flash read errors. Always match voltage range when substituting PIC18F/LF variants.
When should I choose PIC18LF4410 over a PIC18F-K series MCU?
Choose PIC18LF4410 when you need the lowest unit cost for a 44-pin TQFP design with moderate Flash (16KB) and tight Sleep current budget. Migrate to the PIC18F-K series (e.g. PIC18LF25K50) when you need more peripherals such as USB, more PWM channels, or migration headroom beyond 32KB Flash.
Where to download PIC18LF4410-I/PT datasheet PDF?

  • Lower minimum operating voltage than the F variant (vs PIC18F4410-I/PT)

設計ノート

Estimated: at 40 MHz CPU clock with all peripherals active and 3.3V supply, the PIC18LF4410 core draws approximately 11-15 mA (typical 12 mA per datasheet DC characteristics). In Sleep mode with WDT disabled the supply current drops below 0.1 uA. For battery-powered designs, gate all external sensors through a load switch controlled by a MCU GPIO so they can be powered down in Sleep.

Place a 100 nF decoupling capacitor within 5 mm of each VDD/AVDD pin pair (44-TQFP pins 22/23 and 33/34). Add a 10 uF bulk capacitor near the MCU. Use a star-ground topology with separate analog (AVSS) and digital (VSS) ground returns joined only at the MCU ground pins. Keep the MCLR/VPP line short and add the standard 10 kohm pull-up plus 100 nF-to-ground for ICSP in-circuit programming.

Configuration bits (CONFIG1L through CONFIG5L) MUST be set correctly before code will execute. For a 40 MHz operation, configure FOSC = HS-PLL with PLLEN enabled. For LF low-voltage operation at 3.3V, set BOREN to a level appropriate for your brown-out threshold. The MSSP module in I2C mode requires the SDA/SCL pins to be configured as inputs (TRIS bit set) for the slew-rate control to work correctly.

When routing the 44-TQFP out, escape the inner-row pins (RC0-RC7, RA0-RA5, etc.) using micro vias on a 0.4 mm-pitch BGA escape pattern. Route the OSC1/OSC2 traces as short as possible (under 5 mm) and guard them with a ground pour on both sides to minimize EMI pickup. Place a 4.7 kohm pull-up on both SDA and SCL even when the design does not yet use I2C.
