PIC18F86K90-E/PT - 8-Bit 64MHz XLP MCU 64KB Flash 80-TQFP | Microchip
MPN: PIC18F86K90-E/PT ✓ Hoạt độngPIC18F86K90-E/PT Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, a Harvard architecture, on-chip Flash, RAM and peripherals. Within the broader taxonomy, an 8-bit MCU belongs to microcontrollers, which sit under embedded processors, which sit under integrated circuits, which sit under semiconductors. The PIC18 family is Microchip's high-performance 8-bit line, and the XLP 18K sub-family adds nanoWatt XLP extreme-low-power technology for battery-powered products.
Key features include nanoWatt XLP sleep currents as low as 20 nA, a 16 MIPS performance at 64MHz, 64 KB Flash with self-programmability, and 1KB EEPROM for non-volatile data. Connectivity peripherals include I2C, SPI, UART/USART, and LINbus for in-vehicle networking. An integrated LCD driver supports up to 484 pixels for direct segment-LCD glass drive, removing the need for an external LCD controller in metering and appliance displays.
The PIC18F86K90-E/PT uses an enhanced PIC18 Harvard RISC core with 32-bit internal data paths fed from external 8-bit buses, paired with a flexible oscillator block that supports crystal, external clock and internal FRC sources. The CTMU, ADC, comparators and PWM/SCCP peripherals operate from the same low-power core, allowing deterministic control-loop and touch-sensing workloads without waking the CPU. Compared with older PIC18F8722-class parts, the K90 step adds nanoWatt XLP sleep modes and CTMU, while keeping the same address space layout for code migration.
Typical applications include battery-powered industrial meters with LCD and capacitive buttons, automotive body and climate controls, white goods with segment LCDs, and handheld medical devices that demand long battery life. The wide operating range also covers HVAC controls and security keypads where touch panels replace mechanical switches. The PIC18F86K90-E/PT is automotive-grade (E suffix), making it suitable for AEC-Q100 qualified designs.
When designing with this MCU, place a 100 nF decoupling capacitor close to each VDD pin and a bulk 10 uF on the main rail. Choose a low-ESR ceramic for VDD and tie unused I/O to defined logic levels to minimize IADDD leakage in XLP sleep modes. The MPLAB X IDE, MPLAB XC8 compiler and PIC18F-K90 peripheral libraries are the primary development toolchain.

Ứng dụng tiêu biểu
PIC18F86K90-E/PT phù hợp cho 6 Áp dụngs: Battery-Powered LCD Electricity Meter, Automotive Climate and Body Control Modules, White-Good Front Panels with Capacitive Touch, Handheld Capillary Glucose or Pulse Oximeter, Industrial HVAC Keypad and Thermostat, Electronic Shelf Label & IoT Sensor Node.
Battery-Powered LCD Electricity Meter
The PIC18F86K90-E/PT drives a 7-segment LCD glass for residential or industrial utility meters while its CTMU scans up to 24 capacitive touch buttons for tamper detection and user setup. The internal LCD peripheral supports up to 484 pixels across 16 commons, eliminating an external segment-driver IC and shrinking the meter BOM. nanoWatt XLP keeps sleep current in the nanoamp range, allowing a single lithium primary cell to power the meter for 10+ years. The automotive-grade -E suffix also suits outdoor metering cabinets operating up to +125C.

Automotive Climate and Body Control Modules
Vehicle HVAC and body controllers demand a wide VDD tolerance plus AEC-Q100 temperatures, both satisfied by the -E suffix of the PIC18F86K90-E/PT. The MCU's LINbus peripheral talks to in-vehicle body networks while the integrated PWM and capture/compare modules drive DC motors and stepper actuators for vent control. The 64 KB Flash holds module-level firmware plus bootloader, and 4 KB RAM manages multiple LIN frames in parallel. XLP sleep modes allow the cluster to drop below 1 mA when the bus is idle, satisfying parasitic current budgets for the OEM.

White-Good Front Panels with Capacitive Touch
Washing machines, induction cooktops and microwave ovens increasingly replace mechanical buttons with capacitive touch, and the PIC18F86K90-E/PT is built for exactly that. CTMU measures touch via charge-time slope sampling on up to 24 pins, while the LCD driver simultaneously renders icons, segments and seven-segment digits. The 80-pin TQFP leaves plenty of I/O for relays, TRIAC drivers and analog feedback. The -E automotive temperature grade also handles the high ambient temperatures seen behind glass cooking surfaces.

Handheld Capillary Glucose or Pulse Oximeter
Low-power medical instruments such as glucose meters and pulse oximeters rely on the PIC18F86K90-E/PT's nanoWatt XLP sleep currents to stretch battery life for months. The integrated ADC captures blood-glucose strip or photoplethysmography (PPG) analog front-ends while CTMU scans the wake-up touch button and the LCD driver shows the result on a reflective LCD glass. The 64KB Flash comfortably fits USB-CDC stacks or BLE firmware plus rolling 512-event logs in EEPROM. The automotive-grade temperature range simplifies IEC 60601-1 environmental qualification.

Industrial HVAC Keypad and Thermostat
Building automation thermostats often ship with 7-day programmable schedules rendered on segment LCDs. The PIC18F86K90-E/PT powers the panel, drives the LCD glass directly, and uses CTMU to add glass-over-touch buttons that ignore water splashes. UART peripherals link to the wall-bus to a master controller, while the 64MHz core leaves room for an HVAC control algorithm with PID. The wide VDD tolerance (consult datasheet) lets the same design work on 24VAC transformer-fed or 12VDC supply rails.
Được đề xuất
Electronic Shelf Label & IoT Sensor Node
Battery-powered retail electronic shelf labels (ESL) and indoor IoT sensors benefit from the PIC18F86K90-E/PT's nanoWatt XLP sleep current, which lets coin cells survive years between RF transmissions. The integrated LCD driver renders pricing or sensor readings on e-paper or segment LCD without extra controllers, while the USART/SPI ties to a sub-GHz or BLE companion module for wireless updates. 64KB Flash and 4KB RAM hold small RTOS layers plus application payloads, and the -E temperature grade matches warehouse and outdoor retail conditions.

Bảo phân biệt quan trọng
- Integrated CTMU + LCD driver in a single 80-TQFP package (vsPIC18F87K22 + external LCD + touch controller)
- Doubled Flash over PIC18F85K90 siblings (vsPIC18F85K90-I/PT)
- Automotive-grade -E temperature qualification (vsPIC18F86K90-I/PT (industrial))
- nanoWatt XLP ultra-low sleep currents (vsPIC18F8722 (legacy PIC18F))
Ghi chú thiết kế
Estimated: with one ADC active, the K90 core draws on the order of single-digit mA at 64 MHz; activating LCD, timers or UART adds 1-3 mA each. nanoWatt XLP sleep currents are stated in the tens of nA on the datasheet electrical table. Decouple each VDD pin with 100 nF X7R placed as close as practical, and add a 10 uF bulk ceramic on the main supply rail to absorb inrush when waking from sleep.
The CTMU slope measurement is sensitive to leakage on the touch pin - keep the touch pad trace short and isolated from the LCD bias network. Route analog and digital grounds back to a single point near the AVDD/AVSS pins to avoid ground-bounce errors on the ADC. Place quartz crystals and load capacitors within 5 mm of OSC1/OSC2 with a guard ring tied to ground.
Estimated: confusing the -E (automotive) and -I (industrial) temperature grades is a frequent source of late-stage redesigns. The automotive -E grade is required for AEC-Q100 customer programs but typically commands a small price premium. Always validate that the in-circuit debugger pin assignments (PGEC/PGED) match the production package because PT and PT-VAO suffixes can vary in programming pinout.
Thông tin tuân thủ
Per distributor listings the part is RoHS and REACH compliant; the -E suffix indicates AEC-Q100 qualification. Halogen-free status and conflict-minerals declarations should be confirmed with the manufacturer declaration.
