PIC18LF24K22-E/SS Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), data memory (RAM), EEPROM, and a set of peripherals such as timers, ADC, comparators, and communication interfaces onto one die. The PIC18LF family uses a modified Harvard RISC architecture that executes most instructions in one instruction cycle and reaches up to 16 MIPS throughput; the LF prefix indicates a wide operating voltage range that supports low-voltage (LF) operation, which makes the part suitable for battery-powered applications.
Key features include a 48 MHz maximum oscillator input with a 16 MIPS core, nanoWatt XLP extreme-low-power technology for sleep currents in the nanoamp range, an on-chip 10-bit ADC with up to 17 channels, multiple Enhanced USART, MSSP (I2C/SPI), and capture/compare/PWM peripherals. The 256-byte EEPROM supports endurance of up to 1,000,000 erase/write cycles per Microchip datasheet characterization.
The PIC18LF24K22-E/SS uses Microchip's nanoWatt XLP technology that delivers typical sleep currents below 100 nA with retention and features such as ultra-low-power wake-up, system clock gating, and peripheral disable. The wide 1.8V to 3.6V VDD range combined with internal oscillator choices enables battery- or energy-harvesting designs that previously required an external oscillator.
Typical applications include low-battery sensor nodes, portable consumer devices, industrial control panels, USB HID peripherals, and home-automation or IoT endpoints. The combination of XLP sleep current, ADC, PWM, and a rich mix of serial interfaces makes it a flexible general-purpose 8-bit controller for both mains- and battery-powered products.
When designing with this device, ensure that the configured system clock (HS, XT, EC, internal LF-INTOSC) matches the selected VDD range and that the MCLR pin is properly biased (POR) for current voltage. Use ICSP programming on dedicated PGD/PGC pairs to retain the device in-circuit during firmware updates.

Aplicações típicas
PIC18LF24K22-E/SS é adequado para 7 aplicaçãos: Battery-Powered Sensor Node, USB HID Peripheral, Industrial Control Panel, Home Automation / IoT Endpoint, Portable Consumer Device, Automotive Body Electronics (AEC-Q100), Energy Harvesting Wireless Switch.
Battery-Powered Sensor Node
The PIC18LF24K22-E/SS suits battery-powered sensor nodes because its 1.8-3.6V VDD range pairs with nanoWatt XLP sleep currents of ~9 nA typical to extend coin-cell or 2xAA lifetime beyond years. With a 48 MHz HFINTOSC and 16 MIPS throughput, the MCU can wake, sample sensors via its 10-bit ADC across 17 channels, transmit via the EUSART, and re-enter XLP sleep in under a millisecond. The 256-byte EEPROM lets the node store calibration constants across resets without external memory.
Recomendado
USB HID Peripheral
The PIC18LF24K22-E/SS is well-suited to low-speed USB Human Interface Device applications when paired with an external USB transceiver. Its 16 MIPS throughput handles HID report generation, and the 16 KB Flash holds a full HID descriptor plus custom firmware. The 10-bit ADC captures analog control inputs (pots, sliders) while 2 EUSARTs handle debug and external modules. Designers note that this part does not include an integrated USB peripheral; for native USB choose PIC18F14K50.
Recomendado
Industrial Control Panel
The PIC18LF24K22-E/SS supports industrial control panels because its -40 to +125 °C E temperature grade and 1.8-3.6V operating range meet harsh-environment requirements. Its Enhanced Capture/Compare/PWM modules drive motor control signals, while its 10-bit ADC reads back panel sensors. The wide VDD range tolerates regulated 24V-to-3.3V industrial rails with proper power supply design. ICSP allows in-field firmware updates via dedicated programming lines.
Recomendado
Home Automation / IoT Endpoint
The PIC18LF24K22-E/SS fits home automation endpoints because its nanoWatt XLP technology delivers ~9 nA sleep current for battery-powered wireless sensor nodes that report temperature, humidity, or motion. The MSSP (I2C/SPI) peripherals interface to sensors and radios, while 2 EUSARTs can bridge to a host controller or external Wi-Fi/BLE module. The 16 KB Flash supports Zigbee or LoRaWAN stack variants from Microchip's MLA library.
Recomendado
Portable Consumer Device
The PIC18LF24K22-E/SS fits portable consumer electronics such as fitness bands, e-readers, or remote controls because the 1.8-3.6V VDD range allows direct Li-ion battery connection and the nanoWatt XLP technology minimizes sleep current. The 24 I/O pins support 41-segment LCD/LED display drives, while the 16 MIPS CPU handles UI updates and BLE stack integration. The 28-SSOP package is thin enough for wearable form factors.
Recomendado
Automotive Body Electronics (AEC-Q100)
The PIC18LF24K22-E/SS -E grade covers -40 to +125 °C suitable for non-safety automotive body modules such as seat controllers, mirror adjusters, or ambient lighting. For AEC-Q100 qualified automotive applications, designers should consider the PIC18F46K22-I/PT or PIC18F66K22 variants explicitly rated to AEC-Q100. The wide VDD and multiple PWM channels of the K22 family support motor and LED drive in body-electronics designs.
Recomendado
Energy Harvesting Wireless Switch
The PIC18LF24K22-E/SS fits energy-harvesting wireless switches because its nanoWatt XLP sleep current (typically below 100 nA) allows operation from the few microjoules harvested by a piezo press or solar cell. The wide 1.8-3.6V VDD range accepts variable supercapacitor voltages, and the 16 MIPS CPU is fast enough to wake, transmit a packet via the EUSART, and re-enter sleep before the energy reservoir drains. EEPROM stores network pairing data without battery backup.

Notas de projeto
Decouple VDD/VSS pairs (pins 10/9 and 20/19) with 100 nF ceramic capacitors placed within 3 mm of each VDD pin per Microchip DS40001412H. Add a bulk 1-10 uF tantalum or ceramic capacitor on the main supply rail. Use separate analog and digital supply tracks (AVDD/AVSS) when the ADC is active to minimize digital switching noise coupling into analog readings. For nanoWatt XLP designs, enable unused peripherals to their lowest-power state and disable the ADC during sleep to reach the ~9 nA sleep current figure.
Estimated: At 48 MHz / 16 MIPS full-load operation, the PIC18LF24K22-E/SS typically draws ~9 mA active current. With VDD = 3.3 V, power dissipation is ~30 mW per Microchip datasheet DS40001412H. The 28-SSOP package has thermal resistance theta_JA of approximately 80 °C/W, so the junction would only rise ~2-3 °C above ambient at room temperature. No heatsinking is required for typical 8-bit MCU loads. Designers should still verify thermal margin in -40 to +125 °C E grade applications where ambient can approach the upper limit.
Route the OSC1/OSC2 (RA7/RA6) traces short and symmetric to ground when using a crystal oscillator, placing the load capacitors within 2 mm of the OSC pins. Avoid routing digital switching signals under or near the analog AVSS/AVDD tracks to minimize ADC noise. The ICSP PGC/PGD pins (RB6/RB7) must be brought out to a programming header with no series resistors; a 10 kΩ pull-up on MCLR is recommended for normal operation. Leave RA7/OSC1 and RA6/OSC2 accessible even when using the internal oscillator, in case a crystal is needed.
Always read the device-specific silicon errata before committing to the PIC18LF24K22-E/SS - some ADC and CCP modules have documented errata that require workarounds. Do not exceed the absolute maximum VDD of 3.6 V on the LF variant; the 5 V-tolerant PIC18F24K22-I/SS must be selected if 5 V is required. The MCLR pin must never be left floating; tie to VDD through a 10 kΩ resistor to avoid spurious resets. Configure unused I/O pins as outputs and drive them low to minimize current leakage, especially in nanoWatt XLP designs.
