Applications
PIC18LF6722-I/PT is well suited for smart energy meters, industrial data loggers, and multi-node building automation controllers that demand a large Flash capacity alongside low sleep-mode current consumption. Its 128 KB Flash accommodates complex multi-protocol firmware, including Modbus, UART-based displays, and analog sensor acquisition routines, within a single chip. The 2 V minimum supply and nanoWatt XLP sleep currents enable deployment in long-life battery systems such as remote telemetry units and utility meters requiring years of unattended operation.

Frequently Asked Questions
How does PIC18LF6722-I/PT's 128 KB Flash compare to mid-range PIC18 devices and when is the extra memory needed?
At 128 KB, PIC18LF6722-I/PT offers 4× the Flash of a typical 32 KB PIC18, which is necessary when firmware includes a full Modbus stack, encrypted bootloader, and multi-channel calibration tables simultaneously. Industrial gateway designs that aggregate data from 16 or more analog sensors over Modbus RTU routinely consume 80 KB to 100 KB of Flash, leaving 28 KB for future feature additions.
What is the lowest supply voltage PIC18LF6722-I/PT supports and how does this affect energy harvesting designs?
PIC18LF6722-I/PT runs from a minimum of 2.0 V at up to 4 MHz, enabling operation directly from supercapacitors charged by energy harvesting sources such as small solar cells. A 1 F supercapacitor charged to 2.5 V can sustain the MCU for several seconds during a cloud-cover event, bridging gaps in solar energy availability for outdoor wireless sensor nodes.
Which peripheral set does PIC18LF6722-I/PT include for connecting to industrial field devices?
PIC18LF6722-I/PT integrates hardware USART modules supporting up to 1 Mbps, SPI running up to 10 MHz, I2C at 400 kHz Fast mode, and a multi-channel 10-bit ADC. These peripherals enable simultaneous connection to RS-485 transceivers for Modbus, SPI-based flash data storage, I2C real-time clocks, and up to 13 analog sensor inputs without any external interface chips.
For a PCB designer choosing between 64-pin and 80-pin PIC18 variants, what guidance applies to PIC18LF6722-I/PT?
PIC18LF6722-I/PT in TQFP-64 measures 10 mm × 10 mm with 0.5 mm pin pitch, offering up to 54 general-purpose I/O pins. If a design requires more than 54 I/O pins, the 80-pin TQFP variant provides 70 I/O lines at the cost of 20% more PCB area. For most single-board controller designs with fewer than 50 peripheral connections, the 64-pin package minimizes PCB footprint and simplifies routing.
