PIC18LF13K22-I/P - 8KB Flash 8-bit MCU 20-PDIP | Microchip
MPN: PIC18LF13K22-I/P ✓ Hoạt độngPIC18LF13K22-I/P Tóm tắt
An 8-bit microcontroller is a single-chip computer built around an 8-bit data path CPU, typically a RISC or CISC core with on-chip flash, RAM, and peripherals. The PIC18 family extends Microchip's baseline PIC16 architecture with a 16-bit instruction word, hardware multiply, and C-friendly memory models; the LF prefix here indicates the low-voltage variant (down to 1.8 V supply), while the K22 designation places it inside the XLP (eXtreme Low Power) nanoWatt sub-family optimized for battery-powered and always-on applications.
Key features include nanoWatt XLP technology for sleep currents as low as a few tens of nA, a 10-bit ADC with up to 12 channels, multiple PWM/CCP/ECCP modules, and a hardware UART/SPI/I2C peripheral set. The 1.8-3.6 V operating range allows direct connection to single-cell lithium or two-cell alkaline batteries, while internal 32 kHz to 64 MHz oscillator options let designers trade speed against consumption without external crystals.
Architecturally, the device pairs an 8-bit data path with a 16-bit instruction word and 31-level hardware stack, enabling deterministic interrupt response and efficient C compilation with Microchip's XC8 toolchain. The 'LF' low-voltage silicon, combined with XLP peripherals (ultra-low-power wake timers, nanoWatt-managed ADC, deep sleep), positions this part for always-listening edge nodes and energy-harvesting designs that need >10-year coin-cell lifetimes.
Typical applications include battery-powered sensor nodes, low-power IoT endpoints, consumer appliance control panels, and simple human-interface modules. Through-hole PDIP packaging makes the part especially well-suited to prototyping, hobbyist projects, breadboard-based learning kits, and legacy industrial control boards where through-hole assembly remains preferred.
When designing with this device, plan the oscillator configuration carefully: the internal 16 MHz HFINTOSC plus PLL provides 64 MHz FOSC without an external crystal, but USB, CAN, or high-accuracy timing applications still benefit from an external resonator. Verify that any unused I/O pins are configured as outputs (or inputs with the WPU disabled) to minimize sleep current.

Ứng dụng tiêu biểu
PIC18LF13K22-I/P phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Node, Consumer Appliance Control Panel, Hobbyist and Education Development Boards, Remote Control and Wireless Keyfob, Industrial Sensor Transmitter, Edge AI / Always-Listening Wake Detection.
Battery-Powered IoT Sensor Node
The PIC18LF13K22-I/P's 1.8-3.6 V Vdd range lets it run directly from a single CR2032 or 2x AAA battery without a boost converter, while nanoWatt XLP sleep currents in the nA range extend coin-cell lifetime beyond 10 years for periodic wake-and-measure duty cycles. The 10-bit ADC handles analog sensor outputs from thermistors, light sensors, or battery-voltage monitoring. Compared to switching regulators, the LF voltage rail eliminates switching noise that would otherwise couple into a low-amplitude sensor front end, simplifying PCB layout.

Consumer Appliance Control Panel
The 20-pin PDIP through-hole package of the PIC18LF13K22-I/P is well suited to the manual-assembly and field-serviceable control boards inside washing machines, coffee makers, and microwave ovens, where cost-sensitive designs favor hand soldering and a 5 V-tolerant device reduces interface complexity with relay drivers. The hardware UART allows direct connection to a Wi-Fi or BLE module for retrofit-smart variants. Designers benefit from the 256-byte EEPROM for storing user settings and fault history across power cycles.
Được đề xuất
Hobbyist and Education Development Boards
Through-hole 20-pin PDIP makes the PIC18LF13K22-I/P a staple on breadboards and beginner trainer boards where students solder the MCU directly into a perfboard or socketed development platform. The 8 KB flash holds basic C tutorial examples and is supported by the free Microchip XC8 compiler and MPLAB X IDE. Wide operating voltage 1.8-3.6 V also allows demonstration of sleep and brown-out-reset concepts without exotic lab supplies.

Remote Control and Wireless Keyfob
The PIC18LF13K22-I/P's nanoWatt XLP wake-from-sleep current is ideally matched to a battery-powered RF keyfob that sleeps until a button interrupt fires, then transmits and returns to sleep within milliseconds. Hardware SPI interfaces directly to low-cost sub-GHz or 2.4 GHz transceiver ICs; the CCP/ECCP module can drive IR LED PWM for legacy IR remote emulation. Use of 3.3 V reduces battery count and PCB footprint versus 5 V designs.
Được đề xuất
Industrial Sensor Transmitter
Industrial 4-20 mA loop sensor heads often embed a small MCU for linearization, calibration storage, and HART or wireless add-on communication; the PIC18LF13K22-I/P fits thanks to its industrial -40C to +85C temperature grade, 256-byte EEPROM for calibration constants, and 10-bit ADC suitable for bridge-sensor readout. Compared to a discrete op-amp solution, integrating ADC, EEPROM, and CPU into one chip reduces the BOM by roughly 30 percent.
Được đề xuất
Edge AI / Always-Listening Wake Detection
The PIC18LF13K22-I/P's nanoWatt XLP peripheral set includes a RTCC with calendar mode and ultra-low-power ADC sampling, enabling always-listening acoustic or vibration wake-word detection at microamp average current. While the 8 KB flash limits ML, simple feature-extraction threshold checks (variance, zero-crossing rate) fit comfortably. Pair with a higher-tier Cortex-M4 part for full inference, triggered only when the PIC flags an event.

Ghi chú thiết kế
Estimated: at Vdd=3.3 V, 64 MHz active current is approximately 8-12 mA per typical PIC18LF1XK22 datasheet curves. In sleep mode with nanoWatt XLP and RTCC enabled, current drops to single-digit microamps; with RTCC disabled and all peripherals off, current is in the nA range. Place a 100 nF decoupling cap as close as possible to the Vdd pin (pin 20) and a bulk 1-10 uF tantalum or ceramic across Vdd/Vss to filter LED switching transients.
Do not exceed 3.6 V on Vdd for the LF variant - 5 V signals on I/O pins can latch-up the silicon. Use a bidirectional voltage translator (e.g. TXS0108E) when interfacing to 5 V sensors. Also, the MCLR pin (pin 1) is active-low reset; leave it pulled to Vdd via 10 kohm unless low-voltage programming is desired, in which case configure the CONFIG register for MCLRE=OFF and use the ICSP pins for reset.
For the 20-pin PDIP, route the analog signals (RA0-RA5) on the top side and keep digital switching traces (RC2-CCP, RC6-TX, RC7-RX) on the opposite side of the chip to minimize ADC crosstalk. Place the user Vref+ decoupling (RA3) with a 100 nF plus 1 uF pair; noise on Vref+ directly degrades ADC linearity. If the internal HFINTOSC is used, no crystal is required, but keep RC3 (PGM/CLKR) from carrying heavy load to avoid clock jitter on the PWM/ECCP peripherals.
