PIC18F86K90-I/PT Übersicht
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and peripherals (ADC, timers, communication ports, I/O). 8-bit MCUs use an 8-bit data path and are widely deployed where deterministic control, low power, and simple toolchains are needed. Within the broader semiconductor taxonomy, the PIC18F86K90 sits as: MCU -> 8-bit MCU -> PIC18 family -> PIC18F87K90 sub-family -> power-aware XLP line.
Key features include the nanoWatt XLP sleep current (typical values in the nanoamp range for RTC mode), hardware CTMU for capacitive touch and time-of-flight measurement, mTouch capacitive sensing support on up to 24 channels, the integrated LCD driver capable of driving large segmented glass without external charge pumps, an on-chip 8x8 hardware multiplier, and an RTCC with self-calibration. The PIC18F86K90 supports both internal and external oscillator modes with fail-safe clock monitoring for safety-critical designs.
Architecturally, this device uses Microchip's enhanced PIC18 RISC core with 200ns instruction cycle at 20MHz (16 MIPS at 64MHz), a 32-level hardware stack, and a 22-bit instruction word. The XLP technology integrates multiple low-power modes (RUN, IDLE, SLEEP, and deep-sleep), an on-chip low-power RTCC, and ultra-low-power wake-up peripherals, enabling multi-year battery life on coin-cell powered designs.
Typical applications include battery-powered glucose meters and portable medical devices with segment LCDs, industrial metering and utility metering with capacitive buttons, automotive dashboards with LCD displays, IoT sensor nodes with touch interfaces, consumer white goods with LCD readouts, and handheld instrumentation. The combination of segment LCD + capacitive touch + nanoWatt XLP specifically targets single-board battery-powered product designs that previously required multiple ICs.
When designing, place decoupling capacitors within 2-5mm of each power pin pair (VDD/VSS), reserve PCB area for the LCD bias generation components if using external resistor ladders, and configure the CTMU via the application note framework for predictable touch performance. Engineers migrating to this part from earlier PIC18F devices typically retain the same toolchain (MPLAB X, XC8 compiler) and ICD programming interface.

Typische Anwendungen
PIC18F86K90-I/PT ist geeignet für 6 Anwendungs: Battery-Powered Glucose Meter with Segment LCD, Industrial Utility Meter with Capacitive Touch, Automotive Dashboard Display with LCD Readout, Consumer White Goods with Touch HMI, Portable Medical Infusion Pump Controller, IoT Sensor Node with Capacitive Wake-Up.
Battery-Powered Glucose Meter with Segment LCD
The PIC18F86K90-I/PT suits single-board battery-powered glucose meters because of its integrated segment LCD driver (up to 192 pixels), nanoWatt XLP sleep currents in the nanoamp range, and CTMU capability. With 64 KB Flash, the meter can host the full measurement algorithm, calibration tables, and UI strings without external memory; the integrated LCD module replaces an external HT1621-style controller. Engineers can achieve multi-year coin-cell battery life by combining the deep-sleep wake-up RTCC with on-chip LCD bias generation, eliminating external charge-pump components. The PIC18F86K90's 70 I/O pins provide room for the strip-insert port, buttons, and BLE UART link.

Industrial Utility Meter with Capacitive Touch
Industrial water, gas, and electricity meters benefit from the PIC18F86K90-I/PT's integrated segment LCD driver and CTMU-based touch sensing on up to 24 channels. The CTMU converts a touch event into a time-domain measurement without external analog components, supporting sealed front panels (no mechanical buttons). The 12-bit ADC and 4 KB RAM provide headroom for energy/pulse counting algorithms, while 64 KB Flash stores calibration curves and tamper logs. The wide industrial temperature range (-40 to +85 C) supports outdoor meter enclosures, and the nanoWatt XLP architecture allows the design to run from a single Lithium primary cell for the meter's full 10-15 year service life.

Automotive Dashboard Display with LCD Readout
The PIC18F86K90-I/PT's extended-temperature sibling (-40 to +125 C, PIC18F86K90-E/PT) and 70 I/O support secondary cluster displays in automotive dashboards that show trip data, gear position, or HVAC status on a segment LCD. Its CTMU can handle capacitive switch backlighting, and the integrated LCD driver eliminates the need for an external display controller in cost-sensitive trim levels. The device's wide 4.2-5.5 V supply tolerates automotive battery transients when paired with a TVS-protected 5V rail. Designers typically connect this MCU to a CAN transceiver over UART for body-network communication.

Consumer White Goods with Touch HMI
Washing machines, dishwashers, and microwave ovens use the PIC18F86K90-I/PT to combine a segmented LCD display and mTouch capacitive control buttons in a single chip. The CTMU enables sealed front panels with capacitive buttons replacing mechanical switches, improving water-ingress protection (IP65 designs). The PIC18F86K90's 64 KB Flash holds the entire user interface state machine and fault diagnostics, while 4 KB RAM supports spin-cycle profile buffers. Pairing this MCU with a TRIAC driver for motor control and a relay driver for solenoids yields a full white-goods control board with minimal external IC count.

Portable Medical Infusion Pump Controller
Portable infusion pumps use the PIC18F86K90-I/PT as the supervisory controller managing motor speed via PWM, infusion-volume readout on a segment LCD, and clinician-keypad inputs decoded through the CTMU. The nanoWatt XLP deep-sleep modes let the device idle between infusions, extending battery service intervals. Designers value the 12-bit ADC for precise pressure feedback in occlusion detection. The PIC18F86K90's safety-conscious watchdog, fail-safe clock monitor, and code-protection features make it suitable for medical-grade firmware designs where unintended code access must be prevented.
Empfohlen
IoT Sensor Node with Capacitive Wake-Up
Wireless IoT sensor nodes use the PIC18F86K90-I/PT for sensor digitization, segment-LCD local readout, and capacitive-button wake-up that pulls the node out of deep sleep on human touch via the CTMU. The combination of nanoWatt XLP and on-chip LCD enables multi-year battery life on a 2xAA pack, with the LCD showing last-reading on demand. Engineers commonly stack this MCU with a sub-GHz transceiver like the MRF89XA or a BLE module, using UART to forward readings on schedule. The 70 I/O support multiple sensor interfaces (I2C, SPI, analog) on the same PCB.

Wichtigste Unterscheidungsmerkmale
- Mid-density Flash option in 80-pin TQFP family (vs. PIC18F87K90-I/PT)
- Full-feature set in cost-optimized 80-pin variant (vs. PIC18F85K90-I/PT)
- Drop-in same-package migration to extended-temperature grade (vs. PIC18F86K90-E/PT)
Designhinweise
Place 100 nF ceramic decoupling capacitors within 2-5 mm of each VDD/VSS pin pair on the PIC18F86K90-I/PT. The 80-pin TQFP package distributes multiple VDD/VSS pins around the perimeter; missing a single pin pair can introduce logic errors from supply bounce during CTMU or ADC sampling. For battery-powered designs, the on-chip LCD bias generation saves a charge-pump IC but still benefits from a bulk 1 uF-10 uF reservoir near the VLCD pin to suppress LCD-segment ghosting at high segment counts (above 96 pixels).
Route the ICSP programming lines (PGEC1/PGED1 or PGEC2/PGED2) with no series resistors or shared loads, with the MPLAB ICD connector placed at the board edge for in-circuit programming. The CTMU input channels (up to 24) should use guarded PCB traces surrounded by ground pours to suppress noise pickup; if the design also uses the integrated 12-bit ADC, do not route CTMU traces in parallel with ADC analog traces to avoid crosstalk into the ADC result register.
Do not confuse the 'I' suffix (industrial -40 to +85 C) with the 'E' suffix (extended -40 to +125 C); both share the same PIC18F86K90 die and pinout, so they are drop-in compatible but the temperature spec differs. Also note that the PIC18F86K90 5V supply range (4.2-5.5 V) is incompatible with designs targeting 3.3 V operation - for those, use the PIC18F46J-series or PIC18F47K40 parts instead. Finally, ensure the CONFIG words are set correctly to enable the RTCC, watchdog, and code protection features during production programming to prevent accidental lockout.
Compliance-Informationen
RoHS and lead-free status confirmed by Microchip product page. The PIC18F86K90 family is not AEC-Q100 qualified; for AEC-Q100 applications use the automotive-grade PIC18F66K90 or PIC18F67K90 variants. The /PT suffix denotes Pb-free 80-pin TQFP packaging per Microchip ordering nomenclature.
