PIC18LF26K83-E/SS - 8-Bit 64MHz MCU, 64KB Flash, 28-SSOP | Microchip
MPN： PIC18LF26K83-E/SS ✓ 啟用中PIC18LF26K83-E/SS 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals. The PIC18 family is Microchip's high-performance 8-bit architecture offering enhanced instruction set, hardware multiply, and C-optimized design. The LF prefix denotes the low-voltage (F) variant operating down to 1.8 V, while XLP (eXtreme Low Power) targets nanoWatt sleep currents for energy-harvesting and battery-powered designs.
Key features of the PIC18LF26K83-E/SS include 64 KB Flash, 1 KB EEPROM, 4 KB SRAM, a 12-bit ADC2 with up to 25 channels, hardware-touch sensing via Capacitive Voltage Divider (CVD), a CAN 2.0B controller, two I2C/SPI/UART peripherals, five 16-bit timers, and a 64 MHz internal oscillator. The 'E' suffix indicates the Extended operating temperature range (-40 °C to +125 °C), making the device suitable for industrial and harsh-environment deployments.
Architecturally, the PIC18LF26K83 uses a RISC-style 8-bit CPU with a 16-bit instruction word, allowing most instructions to execute in a single clock cycle. The ADC2 peripheral automates averaging, oversampling, and capacitive touch acquisition, offloading signal conditioning from the core. A Peripheral Pin Select (PPS) system allows flexible digital I/O mapping, and the device supports multiple low-power modes (Sleep, Idle, Doze) with nanoWatt XLP technology.
Typical applications include industrial CAN nodes, automotive body electronics, capacitive touch human-machine interfaces (HMIs), sensor nodes with on-chip signal processing, low-power IoT edge devices, and battery-backed instrument clusters. The wide temperature range and CAN bus make it especially attractive for in-vehicle networks and industrial control panels.
When designing with this MCU, ensure adequate decoupling (100 nF + 1 µF) near the VDD pins, route the CAN transceiver differential pair as a 120 Ω impedance-controlled differential line, and configure PPS mappings carefully to avoid peripheral conflicts. The E/SS Extended-temperature grade replaces the I/SS Industrial-grade part when deployments exceed +85 °C ambient.

典型應用
PIC18LF26K83-E/SS 適用於 6 應用s: Industrial CAN Node Interface, Capacitive Touch HMI Panel, Automotive Body Electronics Module, Battery-Powered IoT Sensor Node, Industrial Sensor Signal Conditioner, Medical Monitoring Accessory.
Industrial CAN Node Interface
The PIC18LF26K83-E/SS is well-suited to industrial CAN node designs where it acts as a sensor or actuator controller on a 1 Mbps CAN 2.0B bus. Its integrated CAN controller eliminates an external standalone CAN IC, and the 64 KB Flash / 4 KB SRAM balance supports CANopen or J1939 protocol stacks alongside the application task. The Extended -40 C to +125 C temperature grade handles unheated factory cabinets and outdoor installations, while the 1.8 V to 3.6 V supply permits direct connection to 3.3 V sensor rails without level shifters.
推薦
Capacitive Touch HMI Panel
With its 12-bit ADC2 featuring CVD hardware-accelerated capacitive touch acquisition, the PIC18LF26K83-E/SS can scan up to ~25 touch channels with averaging, filtering, and oversampling handled in hardware. This offloads touch processing from the CPU, allowing the 16 MIPS core to refresh the GUI and drive an SPI display. XLP nanoWatt technology keeps sleep current below 1 µA between user interactions, suiting battery-powered remote controls and wall-mounted control panels.
推薦
Automotive Body Electronics Module
The Extended temperature grade and integrated CAN make the PIC18LF26K83-E/SS a fit for body-control modules controlling lighting, door locks, and seat positioning via LIN-to-CAN gateways or direct CAN slaves. Operating from 1.8 V to 3.6 V supports cold-cranking scenarios down to 6 V battery transients when paired with a front-end regulator. The PPS system maps CAN, UART, and PWM to any I/O pin, simplifying PCB routing in cramped body-control enclosures.
推薦
Battery-Powered IoT Sensor Node
XLP nanoWatt technology on the PIC18LF26K83-E/SS delivers deep-sleep currents in the nanoampere range with peripheral wake-on-touch or wake-on-CAN capability, ideal for years-long battery life in IoT sensor nodes. The 64 MHz core wakes quickly to process sensor bursts, transmit via UART or CAN, and return to sleep, while 4 KB SRAM buffers local measurements between wake events. PPS flexibility permits direct sensor connection without external muxes.
推薦
Industrial Sensor Signal Conditioner
The PIC18LF26K83-E/SS pairs its 12-bit ADC2 with 4 KB SRAM to implement on-chip digital filtering, linearization, and oversampling for bridge, RTD, and thermocouple sensors. Hardware-averaged ADC readings combined with PPS-routed SPI peripheral drives external 24-bit sigma-delta ADCs in mixed-resolution designs. The Extended temperature range accommodates process-control cabinets where ambient temperatures regularly exceed 85 C.
推薦
Medical Monitoring Accessory
In portable medical accessories such as pulse-oximeter dongles, patient-worn event recorders, and connected thermometers, the PIC18LF26K83-E/SS provides the ADC resolution, low-power profile, and CAN/UART connectivity needed for tethered or networked operation. The ADC2 with oversampling averages photodiode or thermistor signals to suppress motion artifact, while XLP sleep extends battery life across multi-day monitoring sessions.

設計說明
Place a 100 nF X7R decoupling capacitor within 5 mm of each VDD/VSS pin pair, plus a bulk 1 µF to 10 µF ceramic near the package. The PIC18LF26K83-E/SS draws peak transient currents during CAN TX and ADC2 conversion bursts; insufficient decoupling causes VDD droop that can reset the brown-out detector (BOR). Estimate: at 64 MHz with active ADC and CAN, IDD peaks near 12 mA.
Route the CANH/CANL pair from RC6/RC7 to the external MCP2562 as a 120 Ω differential microstrip with matched lengths and continuous ground reference. Keep the CAN trace away from switching converter inductors and away from the ICSP ICD pins (RB6/RB7) to avoid radiated emissions during programming.
Do not omit the MCLR pull-up on pin 28 (RE3/MCLR); Microchip recommends a 10 kΩ to VDD and a 100 nF cap to ground for clean reset behavior. Configuring PPS without locking the IOLOCK bit can cause peripherals to remap unexpectedly after a watchdog reset; always lock PPS after configuration. Touch sensing via ADC2 requires the CVD sequence timing to match the datasheet's recommended guard-band - shorter sequences yield noisy readings.
Estimated: at 64 MHz and 3.3 V VDD with active ADC and CAN, average IDD is roughly 8 mA, yielding PD ≈ 26 mW. The 28-SSOP θJA is approximately 95 °C/W (JEDEC EIA/JESD51 still air), producing a junction rise of only ~2.5 °C above ambient, so no heatsink is required even in the +125 °C Extended temperature grade.
