PIC18LF13K22-E/SS Visão geral
An 8-bit microcontroller (MCU) is a small, self-contained computer-on-a-chip that integrates a CPU, program memory (Flash), data memory (RAM), non-volatile storage (EEPROM), and a set of peripherals such as timers, communication ports, ADCs, and digital I/O. 8-bit MCUs sit below 32-bit parts in performance but win on cost, deterministic behavior, and ultra-low power consumption, making them the workhorse of battery-powered sensors, consumer appliances, and industrial control modules.
Key features include a wide 1.8V-3.6V operating range (LF variant), nanoWatt XLP sleep currents in the deep sub-microamp range, CTMU charge-time measurement for capacitive touch, and a peripheral pin select (PPS) block that remaps digital peripherals to a wide choice of I/O pins. The 20-pin SSOP footprint is one of the most common small-outline packages in the industry, easing PCB layout and hand rework.
Architecturally, the PIC18 core uses a 16-bit instruction word with an 8-bit data path and a hardware multiplier, giving most instructions single-cycle execution. Internal oscillator accuracy and the HFINTOSC with PLL deliver 48 MHz system clock from a 16 MHz source, eliminating an external crystal in many applications and reducing BOM cost.
Typical applications include low-power wireless sensor nodes, USB device controllers (in companion with the PIC18F14K50 family), battery-powered home automation modules, capacitive touch user interfaces, small appliance control boards, and industrial sensor signal conditioning. The "LF" prefix identifies the low-voltage variant; the parallel "F" part (PIC18F13K22-E/SS) is the 2.0V-5.5V version.
When designing with this part, plan decoupling close to VDD/VSS, leave room for the ICSP/ICD programming header, and check the PPS mapping table against your chosen pinout before committing to PCB layout. The XLP current data in the datasheet should be used directly for battery-life calculations rather than estimated.

Aplicações típicas
PIC18LF13K22-E/SS é adequado para 6 aplicaçãos: Battery-Powered Wireless Sensor Node, Capacitive Touch User Interface, Home Appliance Control Board, Industrial Sensor Signal Conditioning, USB HID / CDC Device Companion, Portable Medical / Wellness Device.
Battery-Powered Wireless Sensor Node
The PIC18LF13K22-E/SS is a natural fit for battery-powered wireless sensor nodes thanks to its nanoWatt XLP technology and 1.8V-3.6V LF supply range. Sleep mode current in the deep sub-microamp range lets a coin cell or 2xAA pack run for years while the MCU wakes periodically to sample and transmit. The 8 KB program memory holds a small RTOS or scheduler plus an IEEE 802.15.4 or LoRa driver for companion radios. CTMU-based temperature sensing or external sensor reading via the 10-bit ADC runs directly off the analog pins. Engineers designing wearables, environmental loggers, and remote HVAC monitors benefit from the SSOP-20 footprint that pairs easily with low-cost 2-layer PCBs.
Recomendado
Capacitive Touch User Interface
The PIC18LF13K22-E/SS integrates Microchip's CTMU (Charge Time Measurement Unit), enabling reliable capacitive touch sensing on up to 16 channels without external touch ICs. Combined with nanoWatt XLP sleep currents in the nanoamp range, this part powers touch buttons and sliders on battery-powered appliances, locks, and remote controls that wake on touch and return to deep sleep. The 8 KB Flash accommodates mTouch firmware libraries and small application code; the 10-bit ADC reads CTMU charge timing to detect finger presence. The SSOP-20 footprint leaves enough pins for a matrix of 4x4 keys plus LEDs and a UART to a host controller.
Recomendado
Home Appliance Control Board
The PIC18LF13K22-E/SS suits small home appliances such as coffee makers, fans, blenders, and dishwashers where its 1.8V-3.6V supply (LF variant) interfaces directly with 3.3V sensors and BLE/Wi-Fi co-processors. EUSART and MSSP (SPI/I2C) talk to BLE SoCs, OLED displays, and EEPROM for settings storage. The 16 MIPS throughput runs small state machines, PID temperature loops, and BLE command parsers without external DSP. The SSOP-20 footprint, hand-solderable and reworkable, suits small-batch appliance manufacturing and field service. nanoWatt XLP idle currents help meet Energy Star standby targets.
Recomendado
Industrial Sensor Signal Conditioning
The PIC18LF13K22-E/SS handles industrial 4-20 mA loop-powered sensor signal conditioning when paired with a low-dropout regulator and 16-bit sigma-delta ADC front end. Its 10-bit on-chip ADC suffices for coarse threshold detection while an external ADC handles precision conversion. The PIC18LF13K22-E/SS reads limits, drives an alarm LED, switches a relay via MOSFET, and reports status over RS-485 using the EUSART. The E (extended) temperature grade supports -40C to +125C operation in unconditioned cabinets. The SSOP-20 footprint and 1.8V minimum supply keep standby power below 1 mW, well within loop-power budgets.
Recomendado
USB HID / CDC Device Companion
The PIC18LF13K22-E/SS itself lacks USB, but acts as a UI coprocessor beside USB-capable MCU parts (for example PIC18F14K50-I/SO), running capacitive touch, display, and indicator logic while the USB part handles enumeration. The PIC18LF13K22-E/SS exchanges data with the USB host over SPI or UART. Both MCUs share the same 3.3V supply and SSOP-20 PCB footprint pattern, simplifying layout. The PIC18LF13K22-E/SS handles debounce, animation, and power-mode management without burdening the USB MCU. Drop-in software compatibility with the PIC18F13K22-E/SS means a single firmware base can be recompiled for either part.
Recomendado
Portable Medical / Wellness Device
The PIC18LF13K22-E/SS powers portable medical and wellness devices such as pulse oximeters, thermometers, and pillbox reminders where battery life, deterministic firmware, and small footprint matter. Its 8 KB Flash accommodates basic signal-processing and BLE pairing logic, and the nanoWatt XLP deep-sleep mode keeps standby current below 1 uA for months of shelf life on a CR2032. The LF variant's 1.8 V minimum allows direct operation from a single alkaline or silver-oxide cell. The 10-bit ADC reads photodiode or thermistor front ends; CTMU drives touch buttons. SSOP-20 is hand-solderable for low-volume clinical pilots.

Principais diferenciais
- Wider voltage range down to 1.8 V (LF) (vs PIC18F13K22-E/SS)
- Extended -40 C to +125 C temperature grade (E) (vs PIC18LF13K22-I/SS)
Notas de projeto
For PIC18LF13K22-E/SS, place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 14) and a bulk 10 uF capacitor near the supply rail. Use the LF variant's 1.8 V minimum to allow direct coin-cell operation; if a switching regulator is upstream, ensure its output ripple stays below 50 mVpp to avoid ADC reference noise coupling. nanoWatt XLP sleep currents (tens of nA) only hold when the watchdog, ADC, and peripherals are explicitly disabled in software.
Route the ICSP/ICD pins (PGC/PGD, typically RB6/RB7 or RA6/RA7 on this family) to a 2x3 or 1x6 header with no series resistors between MCU and header - Microchip ICD tools drive these directly. Keep the ICSP header away from switching regulators and high-current traces to avoid programming glitches on noisy boards. Maintain a ground copper pour under the SSOP-20 footprint and stitch VSS to it on multiple vias to reduce ground bounce.
Common pitfall is using PIC18LF13K22-E/SS firmware on the PIC18F13K22-E/SS (or vice versa) without re-checking voltage. PIC18F parts need at least 2.0 V and can fail to start at 1.85 V brown-out conditions; PIC18LF parts need at least 1.8 V. Brown-out voltage (BOR) settings must be re-flashed when migrating between LF and F grades. Also, the PPS (peripheral pin select) remapping table differs across K22 variants - always recompile and re-verify pin assignments in MPLAB X.
