PIC18LF6722-I/PT Descripción general
An 8-bit microcontroller (MCU) is a single-chip processor with an 8-bit data path, on-chip Flash/ROM, RAM, peripherals and interrupt logic - positioned in the hierarchy 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. Compared with 32-bit Cortex-M MCUs, 8-bit parts draw less power and cost less per unit but deliver lower MIPS and addressable memory; the PIC18F line bridges the gap with C-compilable Harvard architecture, hardware 8x8 multiplier and prioritized interrupts.
Key features include 1024 bytes of data EEPROM for non-volatile parameter storage, 70 free I/O pins with peripheral pin-select on most pins, an enhanced 16-bit capture/compare/PWM module, two analog comparators, and a 10-bit A/D converter with up to 12 channels. The 64-TQFP package exposes nearly the full silicon pin complement, enabling interface-rich designs without external glue logic. The /PT suffix denotes the 64-pin TQFP industrial-temperature (-40C to +85C) package, the 'I' grade.
Typical applications are large, low-power embedded systems with multiple serial interfaces: industrial sensor hubs, home-automation controllers, automotive body modules (LIN slaves), instrument clusters and USB-to-UART bridges when paired with an external transceiver. The 1024-byte data EEPROM allows non-volatile storage of calibration tables, serial numbers and user preferences without external NVRAM, and the wide 2.0V-5.5V VDD range supports 3.3V and 5V rails from a single part.
When designing with this device, place a 100 nF decoupling capacitor within 5 mm of each VDD/VDDCORE pin pair, locate the crystal within 10 mm of OSC1/OSC2 with short symmetrical traces, and respect the ICSP pins (PGC/PGD/MCLR/VPP) to retain in-circuit programming in production. Migrating to the standard PIC18F6722 (4.2V-5.5V) requires VDD never drop below 4.2V to preserve Flash endurance.

Aplicaciones típicas
PIC18LF6722-I/PT es adecuado para 6 aplicacións: Industrial Sensor Hub, Home-Automation Controller, Automotive Body Module (LIN Slave), Instrument Cluster Display Driver, USB-to-UART Bridge Module, Battery-Backed Data Logger.
Industrial Sensor Hub
The PIC18LF6722-I/PT fits industrial sensor hubs that aggregate data from multiple analog and digital sources. Its 10-bit A/D converter with up to 12 input channels digitizes thermocouple, pressure and 4-20 mA sensor outputs, while the four serial interfaces (2x UART LIN-capable + 1x SPI + 1x I2C) connect to downstream sensor nodes and external EEPROM. The 2.0V-5.5V VDD range lets the part run from a regulated 24V-to-5V industrial rail or a 3.3V backup supply. nanoWatt idle modes drop quiescent current below 1 uA typical between sensor reads, preserving energy in remote installations. The 64-TQFP package exposes 70 GPIO for status LEDs, relay drivers and keypad scanning without external mux ICs.
Recomendado
Home-Automation Controller
The PIC18LF6722-I/PT anchors home-automation controllers that orchestrate HVAC, lighting, blinds and security subsystems. Its dual UARTs handle RS-485 lighting buses and LIN thermostats, while the SPI port drives a TFT or OLED display and the I2C port reads RTC and external EEPROM. The 128 KB Flash supports a full Modbus or BACnet stack plus user-interface logic without external program memory. The 1024-byte data EEPROM stores commissioning parameters and user preferences, surviving power cycles without external NVRAM. The wide 2.0V-5.5V range lets the controller run from 3.3V PoE or 5V USB supplies interchangeably, simplifying enclosure design.
Recomendado
Automotive Body Module (LIN Slave)
The PIC18LF6722-I/PT is well suited to automotive body-electronics LIN slaves for door modules, seat controllers and mirror adjusters. Its two LIN-capable UARTs drive the LIN bus plus a K-line diagnostic interface, while the 10-bit A/D reads potentiometer wiper positions for seat travel feedback. The enhanced 16-bit CCP/PWM module smoothly drives window-lift and mirror-fold motors with hardware dead-band control. The industrial -40C to +85C temperature grade covers cabin environments, and the 2.0V-5.5V VDD range tolerates automotive cold-start cranking voltage drops. The 1024-byte EEPROM stores end-of-line calibration and vehicle option codes for service traceability.
Recomendado
Instrument Cluster Display Driver
The PIC18LF6722-I/PT drives small instrument clusters in two-wheelers, e-bikes, industrial gauges and laboratory equipment. Its 10-bit A/D reads up to 12 analog channels (speed, fuel, temperature, battery voltage) while the enhanced CCP/PWM generates dimmable backlight control signals. The MSSP in SPI mode streams gauge data to an external LED driver or small TFT controller, and the UARTs provide LIN or RS-232 diagnostic links to service tools. With 70 GPIO the part directly keys the segment LCD or LED array without external latches, and 1024 bytes EEPROM stores odometer and service-interval counters in non-volatile memory.
Recomendado
USB-to-UART Bridge Module
The PIC18LF6722-I/PT forms the MCU core of USB-to-UART bridge modules when paired with an external USB transceiver such as the MCP2200 or MCP2221. The two hardware UARTs provide primary and auxiliary serial channels at up to 5 Mbps each, ideal for debug consoles and field firmware updates. The 128 KB Flash stores the USB CDC stack plus vendor-specific protocol handlers, and the 1024-byte EEPROM retains VID/PID/serial-string descriptors without re-enumeration after power cycle. The wide 2.0V-5.5V VDD range supports both USB-bus-powered 5V and self-powered 3.3V designs. nanoWatt idle current below 1 uA keeps bus-powered standby within USB suspend-current limits.
Recomendado
Battery-Backed Data Logger
The PIC18LF6722-I/PT powers battery-backed data loggers in remote environmental, asset-tracking and cold-chain monitoring applications. Its 10-bit A/D with 12 channels digitizes temperature, humidity and shock sensors, while the 1024-byte EEPROM plus 128 KB Flash provides redundant non-volatile storage for log records spanning months of unattended operation. The four serial interfaces attach to BLE or LoRa radio modules via UART/SPI for wireless upload, and to I2C RTC chips for timestamping. nanoWatt sleep currents below 1 uA typical and the 2.0V-5.5V VDD range let the logger run for years on a single Li-coin cell, with industrial -40C to +85C operation covering outdoor deployment.

Notas de diseño
Estimated: at 40 MHz CPU and 5.0V VDD, the PIC18LF6722-I/PT core current draw reaches ~15 mA typical with peripherals active. Place a 100 nF decoupling capacitor within 5 mm of each VDD/VSS pin pair (5 pairs on this 64-TQFP) and add a bulk 10 uF tantalum or ceramic at the regulator output. For battery-backed nodes, use nanoWatt sleep modes with RTC sourced from Timer1 to drop quiescent current below 1 uA typical.
The 64-TQFP package requires a 4-layer PCB with a continuous ground plane directly under the IC for thermal dissipation and EMI control. Route the crystal traces from OSC1/OSC2 (pins 20/19) within 10 mm and guard them with a ground keep-out zone to avoid crosstalk; the ICSP pins PGC/PGD (RB6/RB7, pins 29/30) must remain accessible in production for in-circuit programming and debug.
Estimated: configuring a pin as analog input without clearing the corresponding TRIS bit can result in contention and excess current. The 10-bit A/D requires acquisition time of at least 1.4 us at 40 MHz; failing to honor TACQ produces noisy readings. When migrating between the LF (2.0V-5.5V) and F (4.2V-5.5V) variants, verify that VDD never drops below 4.2V or Flash endurance is reduced; check the BOR configuration for proper brown-out behavior in your application.
The PIC18LF6722-I/PT's four serial interfaces (2x UART LIN-capable + SPI + I2C) are 5V tolerant when the part runs at 5V VDD; mixing 3.3V peripherals at 5V VDD requires series resistors or level shifters on each I/O line. The LIN-capable UARTs include hardware baud-rate detection but require careful configuration of BRG and the auto-baud detector bit sequence - reference Microchip application note TBANEL for lin-bus timing compliance.
