PIC18LF8410-I/PT - 40MHz 8-bit MCU, 16KB Flash, 80-TQFP | Microchip
MPN: PIC18LF8410-I/PT ✓ Hoạt độngPIC18LF8410-I/PT Tóm tắt
An 8-bit PIC microcontroller is a Harvard-architecture MCU built around a RISC instruction set with separate program Flash and data RAM buses. The PIC18 family extends the baseline PIC16 instruction set with 16-bit opcodes, hardware multiply, linear data memory, and C-friendly call stack, placing it in the 8-bit MCU -> PIC18 family -> Microchip 8-bit portfolio hierarchy. Compared with legacy PIC16 parts, PIC18 cores offer roughly 4x-10x throughput at the same clock frequency and add peripheral-rich variants such as the PIC18LF8410.
Key features of the PIC18LF8410-I/PT include 16 KB (8K x 16) Flash, 768 bytes SRAM, 1 KB EEPROM, a 10-bit ADC up to 12 channels, two Enhanced USART modules, two MSSP (SPI/I2C) modules, two CCP and three ECCP (PWM) modules, a 16-bit timer, three 8-bit timers, an ultra-low-power nanoWatt sleep mode (down to ~100 nA), and an ICD/ICSP debug interface. The wide 2.5 V-5.5 V supply range allows direct connection to 3.3 V or 5 V rails.
Architecturally, the device combines a 16-bit instruction word Flash with a 16-bit-wide data path and an 8-level hardware stack, plus Microchip's nanoWatt Technology dynamic power management that scales clock and bias current to the active peripheral set. The 70 I/O pins are shared with on-chip peripherals through independent PPS-less mapping, simplifying PCB routing.
Typical applications include industrial control panels, HVAC and white-goods motor control, automotive body electronics (non-AEC-Q100), USB/serial human-interface devices, networked sensor nodes, and consumer display controllers. The wide voltage range and rich peripheral set make the part well suited for mixed-signal designs that need analog sensing, PWM drive, and communication on the same board.
When designing with the PIC18LF8410-I/PT, place a 100 nF decoupling cap adjacent to every VDD/AVDD/VSS pin pair and reserve at least 4 KB of program memory for bootloader or future firmware updates. The 70 I/O budget allows direct fan-out to keypads, LED matrices, and parallel-character LCDs without external I/O expanders.

Ứng dụng tiêu biểu
PIC18LF8410-I/PT phù hợp cho 6 Áp dụngs: Industrial Control Panels, HVAC and White-Goods Motor Control, Automotive Body Electronics, USB/Serial Human Interface Devices, Networked Sensor Nodes, Consumer Display Controllers.
Industrial Control Panels
The PIC18LF8410-I/PT's 70 I/O pins and wide 2.5 V-5.5 V supply make it a strong fit for industrial control panels that multiplex keypads, LED indicators, relay drivers, and character LCDs on a single board. The 16 KB Flash stores a full IEC 9.1-compliant menu state machine plus Modbus framing, while the 10-bit ADC reads panel-mounted sensors for temperature, pressure, and current monitoring. With two EUSARTs, the part drives both an isolated RS-485 fieldbus to a PLC and a local HMI console. Compared with smaller PIC18 parts, the 70 I/O budget eliminates external I/O expanders, reducing BOM cost. The -40 C to +85 C industrial temperature grade and robust EEPROM endurance (1M erase/write cycles) suit factory-floor deployments.

HVAC and White-Goods Motor Control
The PIC18LF8410-I/PT's three ECCP (Enhanced Capture/Compare/PWM) modules are ideal for HVAC blower, damper, and compressor motor control, providing up to 6 complementary PWM outputs with programmable dead-band and fault inputs. Its 40 MHz CPU sustains closed-loop RPM control loops within 25 us, while the 10-bit ADC simultaneously monitors motor current, supply voltage, and NTC temperature. The wide 2.5 V-5.5 V supply tolerates rectified mains drops on white-goods boards without brown-out resets. The 16 KB Flash holds full sensorless BLDC or trapezoidal commutation tables, and nanoWatt Technology reduces standby draw below 1 uA during off-cycles - critical for Energy Star compliance.

Automotive Body Electronics
The PIC18LF8410-I/PT serves automotive body modules such as door-zone controllers, seat-position memory units, and lighting controls where 16 KB Flash and 70 I/Os outshine smaller PIC18s. The two EUSARTs implement LIN (Local Interconnect Network) slaves and a body-domain CAN gateway via external transceivers, while three ECCP modules drive LED matrix dimming with PWM at 1 kHz to avoid flicker. Note that this is the LF (industrial-grade) variant, not AEC-Q100 qualified; for AEC-Q100 applications Microchip offers the PIC18F84K22-I/PT or PIC18F66K80-I/PT family. The wide supply tolerates load-dump transients down to 2.5 V during cranking.

USB/Serial Human Interface Devices
The PIC18LF8410-I/PT is well suited to custom HID peripherals such as industrial keyboards, jog-shuttle controllers, and serial-to-USB converters that require up to 70 I/Os for key-matrix scanning or LED status. With one EUSART and one MSSP configured for SPI, the part bridges a legacy RS-232 industrial instrument to a USB host via an external MCP2200 or MCP2221 USB-UART bridge. The 16 KB Flash holds USB HID descriptor tables plus key-debounce and macro logic, while the 10-bit ADC reads analog joysticks or rotary encoders. nanoWatt Technology puts the unused device to sleep between user inputs, reducing idle current to below 100 nA on battery-powered field controllers.
Được đề xuất
Networked Sensor Nodes
The PIC18LF8410-I/PT powers IoT edge nodes and industrial sensor transmitters that aggregate analog and digital inputs and forward them over RS-485 or Modbus. Its 12-channel 10-bit ADC directly samples thermocouples, RTDs, and 4-20 mA loops without an external MUX, while the two EUSARTs implement a Modbus master and slave simultaneously for daisy-chained sensor networks. The 16 KB Flash holds complete sensor-linearization libraries, and nanoWatt Technology drops quiescent current below 1 uA between conversions, extending battery life in field-mounted wireless gateways. The 70 I/Os accept both digital contact closures and analog signals on the same board.
Được đề xuất
Consumer Display Controllers
The PIC18LF8410-I/PT drives segment-LCD or graphical-TFT controllers in consumer appliances and audio front-panel displays. Its 70 I/Os drive up to 14 multiplexed digit pins or serve as parallel-TFT data lines for 3.5-inch displays, while the three ECCP modules generate LCD contrast PWM and backlight dimming at 200 Hz to avoid flicker. The 40 MHz CPU sustains 30 Hz refresh on 320x240 TFTs via software bit-banging, eliminating an external graphics controller. The wide 2.5 V-5.5 V supply matches single-cell Li-Ion or USB-derived rails, and nanoWatt Technology drops standby below 1 uA when the panel is off.

Ghi chú thiết kế
Place a 100 nF ceramic decoupling capacitor as close as physically possible to every VDD/AVDD/VSS pin pair (pins 6/7, 16/17, 32/33, 42/43, 52/53, 62/63, 73/74), plus a bulk 10 uF tantalum at the board-level supply. The LF-family wide supply range (2.5 V-5.5 V) tolerates 3.3 V and 5 V rails directly without a separate LDO. Use a supervisor (e.g., MCP1316) on VDD to ensure clean brown-out reset behavior below 2.3 V. nanoWatt Technology reduces idle current to below 1 uA - leave the Sleep command reachable from any interrupt handler so unattended nodes save power.
The 80-pin TQFP package has a theta_JA of approximately 51 C/W (estimated, from 12x12 mm 4-layer JEDEC test board). At maximum 40 MHz CPU speed drawing roughly 25 mA active, the device dissipates around 130 mW (5 V x 25 mA), giving a junction temperature rise of approximately 7 C above ambient - well within the 125 C junction limit. No external heatsink is required. In forced-air enclosures, leave at least 5 mm clearance around the TQFP to prevent hot-spot accumulation.
Route the 40 MHz CPU traces (OSC1/OSC2 crystal traces to pins 63/64) as short as possible and surround them with a ground guard ring to limit EMI. Keep digital I/O traces (PORTA-PORTG) at least 3 mm away from the analog AVDD/AVSS pair on pins 22/23 to preserve ADC accuracy. Place the ICSP programming header (RB6/RB7 pins 30/31 plus MCLR pin 9) on a 0.1-inch single-row header so production programming via PICkit 3/4 works without rework. Use a 4-layer stack-up with continuous ground plane under the TQFP body for thermal spreading.
Do not assume the LF supply range (2.5 V-5.5 V) applies to the F variant - the PIC18F8410-I/PT requires at least 4.2 V and will brown-out below 4 V. Avoid tying the MCLR pin (pin 9) directly to VDD; use the recommended 10 kohm pull-up plus a 1 nF cap to allow ICD reset. Code-protect fuses must be programmed last; setting them mid-development prevents re-flashing via ICSP. The EEPROM (1 KB) is rated for 1M erase/write cycles - use wear-leveling firmware if updates exceed 100/day.
Thông tin tuân thủ
LF (industrial, -40C to +85C) variant, not AEC-Q100 qualified. RoHS compliant per Microchip product page (LEAD FREE marking). For automotive applications, choose the PIC18F84K22-I/PT (AEC-Q100) family instead.
