PIC18LF8410T-I/PT - 8-bit 40MHz 16KB Flash MCU | Microchip
料号： PIC18LF8410T-I/PT ✓ 量产中PIC18LF8410T-I/PT 概述
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (FLASH), data memory (RAM), non-volatile EEPROM, and a rich set of peripherals on one die. The PIC18 family sits within Microchip's PIC microcontroller hierarchy, which spans PIC10 -> PIC12 -> PIC16 -> PIC18 -> PIC24 -> dsPIC30/33 -> PIC32, walking from 8-bit baseline designs to 32-bit MIPS-based cores. Within the PIC18 hierarchy, the F8410 belongs to the PIC18F6310/6410/8310/8410 sub-family, distinguished by its large pin count (70 I/O), generous peripheral set, and power-saving nanoWatt XLP technology.
Key features include 70 general-purpose I/O pins, 10-bit ADC, multiple USART/SPI/I2C interfaces, and 12-bit Enhanced PWM outputs for motor and lighting control. The device integrates nanoWatt XLP technology for ultra-low-power sleep modes drawing sub-microamp currents, making it suitable for battery-powered applications. It offers self-programmable FLASH under software control and supports in-circuit debugging via ICD.
The architecture combines a RISC Harvard-bus core with 16-bit instructions and 8-bit data paths, achieving up to 10 MIPS at 40MHz. Internal peripherals are interconnected through Microchip's Peripheral Pin Select (PPS) and configurable logic cells, providing flexible signal routing. The 80-TQFP package exposes all peripherals and I/O while accommodating a 12x12 mm footprint with 0.5 mm pitch, suitable for industrial designs requiring many external connections.
Typical applications include industrial control panels, automotive body and HVAC modules, consumer appliances, motor control boards, and battery-powered sensor hubs. The PIC18LF8410T-I/PT's wide 2.0V-5.5V operating range and nanoWatt XLP modes make it ideal for energy-conscious designs.
Designers should evaluate the oscillator configuration (HS vs. internal RC), decoupling strategy (100nF on each VDD/VSS pair), and unused-pin tie-offs per Microchip's PIC18F6310/6410/8310/8410 family datasheet to ensure robust EMI performance. Consider migrating to PIC18F66K80 or PIC18F67K40 for newer designs that require CAN, USB, or higher analog performance.

典型应用
PIC18LF8410T-I/PT 适用于 6 应用s: Industrial Control Panel, Appliance Motor Control Board, Automotive Body Control Module, Battery-Powered Sensor Hub, Consumer Appliance User Interface, Medical Monitoring Device.
Industrial Control Panel
The PIC18LF8410T-I/PT fits industrial control panels because its 70 I/O pins in 80-TQFP expose enough GPIO for keypad scanning, LED multiplexing, LCD driving, and parallel sensor buses without external I/O expanders. The 40 MHz / 10 MIPS core handles Modbus or proprietary serial protocols on USART while simultaneously servicing a 10-bit ADC for analog process variables (temperature, pressure, flow). The 2.0-5.5 V supply range simplifies design for both 24 V-bus-derived 5 V and 3.3 V logic rails, and the nanoWatt XLP Sleep mode supports panel push-button wake scenarios with sub-microamp standby current.
推荐
Appliance Motor Control Board
In washing machines, dishwashers, and HVAC blower controllers, the PIC18LF8410T-I/PT's Enhanced PWM outputs and 10-bit ADC drive brushless-DC or universal motors with closed-loop current sensing. The 16 KB FLASH accommodates sensorless FOC or trapezoidal commutation firmware plus a UI state machine, and 768 B RAM is enough for ring buffers and PID scratch variables. The wide 2.0-5.5 V operating range survives brown-outs common on compressor inrush, while nanoWatt XLP modes keep standby power below regulatory thresholds for ENERGY STAR appliances.
推荐
Automotive Body Control Module
The PIC18LF8410T-I/PT is well suited to automotive body controllers managing seat, mirror, and lighting functions, with 70 I/O sufficient for multi-channel load driving via MOSFET pre-drivers. The 10-bit ADC reads battery voltage and current-shunt amplifiers for short-circuit detection, while USART/SPI/I2C peripherals communicate with companion BCM chips over LIN or proprietary buses. For under-hood or AEC-Q100-qualified deployments, designers should migrate to PIC18F66K80 or PIC18F67K40, but for cabin-rated body modules the LF8410 offers a cost-effective path.
推荐
Battery-Powered Sensor Hub
The PIC18LF8410T-I/PT operates directly from a 1S Li-Ion (3.0-4.2 V) or 2x AA battery stack thanks to its 2.0-5.5 V supply range, eliminating the need for an external LDO in cost-sensitive wireless sensor nodes. nanoWatt XLP technology provides Sleep currents in the sub-microamp regime and a Real-Time Clock/Calendar mode for periodic wake events, supporting multi-year battery life on duty-cycled environmental or asset-tracking sensors. The 16 KB FLASH accommodates 802.15.4 or LoRaWAN MAC stacks for sub-GHz radio co-processors over SPI, while the 10-bit ADC reads thermistor, photocell, or MEMS sensor outputs.
推荐
Consumer Appliance User Interface
The PIC18LF8410T-I/PT powers the user-interface board in coffee machines, microwaves, and refrigerators, where its 70 I/O drive segmented LCDs, capacitive-touch keypads, rotary encoders, and triac-controlled heaters. The 10 MIPS core renders animated icons on character or graphical LCDs without visible latency, and 16 KB FLASH holds multilingual UI strings plus state-machine code. nanoWatt XLP Sleep mode keeps standby power below 0.5 W for EU eco-design compliance, and the 2.0-5.5 V supply simplifies powering from 5 V USB or rectified 12 V mains.
推荐
Medical Monitoring Device
The PIC18LF8410T-I/PT fits non-critical medical monitoring peripherals such as digital thermometers, blood-pressure cuffs, and pulse oximeters where its 10-bit ADC and 70 I/O handle sensor readout, pump/valve drivers, and LCD display. The deterministic PIC18 RISC pipeline simplifies FDA 510(k) firmware verification, and nanoWalt XLP Sleep supports battery-only operation across multi-day monitoring sessions. Designers must validate IEC 60601-1 EMI/ESD margins and add a separate watchdog supervisor for fail-safe operation; for active implantable or life-support uses, migrate to a higher-MIPS Cortex-M part.

设计说明
Decouple every VDD/VSS pair with a 100 nF X7R ceramic placed within 3 mm of the pin, and add a bulk 4.7-10 uF tantalum or ceramic near the package. The PIC18LF8410T-I/PT draws brief transients during FLASH writes; insufficient decoupling can trigger spurious BOR resets. For battery-powered designs, gate the analog supply (AVDD) with a ferrite bead to reduce MCU digital switching noise coupling into ADC readings, and use the internal 1.024 V reference or an external low-noise reference for best ADC performance.
Route the 40 MHz crystal traces (OSC1/OSC2) short and symmetric with a grounded guard ring, keeping them away from high-current switching traces. Place the ICSP connector (PGEC1/PGED1) at the board edge with no series resistors on the programming lines to avoid ICD handshake failures. The 80-pin TQFP's 0.5 mm pitch tolerates 4 mil traces with 4 mil spaces on a 4-layer PCB using standard FR-4; for harsh industrial EMI environments, increase to 6 mil spacing per IPC-2221.
Do not leave unused I/O floating - configure them as outputs driving low or as inputs with the internal weak pull-up enabled, otherwise Shoot-through current on the input buffer can raise I_DD by 1-2 mA and degrade ADC accuracy. When migrating from PIC18F8410 to PIC18LF8410, verify that the application stays within the LF's 2.0 V minimum at all times including cold-start and battery-end-of-life. Finally, configure the Configuration bits (CONFIG1H/L, CONFIG2H/L, etc.) explicitly in code; relying on factory defaults risks BOR and oscillator misconfiguration in production.
