PIC18F86K90-I/PTRSL - 8-bit 64MHz 64KB Flash MCU | Microchip
MPN： PIC18F86K90-I/PTRSL ✓ 啟用中PIC18F86K90-I/PTRSL 概覽
A microcontroller (MCU) is a single-chip computer that combines a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripheral IP such as timers, ADC, communications controllers, and I/O. Within the broader taxonomy, the PIC18F86K90 belongs to the 8-bit MCU family -> PIC18 sub-family -> PIC18FxxK90 LCD-driver family -> PIC18F8xK90 80-pin members. It targets battery-powered LCD applications that combine touch sensing, segmented display driving, and ultra-low standby current in the same silicon.
Key features include nanoWatt XLP™ technology for deep-sleep currents measured in nanoamps, an integrated LCD driver supporting up to 192 segments, a Charge Time Measurement Unit (CTMU) that enables capacitive touch and simple temperature measurement, 24 channels of 12-bit ADC, multiple UART/SPI/I²C interfaces, and an operating voltage range of 1.8V to 5.5V. The 'I' temperature grade denotes an industrial -40°C to +85°C operating range, and 'PTRSL' indicates the 80-pin TQFP (PT) package shipped in tape-and-reel (TR) orientation with SL suffix marking.
Architecturally, the device uses an enhanced Harvard RISC core with a hardware multiplier, 31-level stack, and a C-friendly instruction set, allowing efficient C compilation through Microchip's MPLAB XC8 toolchain. The 80-pin TQFP exposes the full peripheral set: ample digital I/O, the full LCD segment bus, and CTMU-driven touch channels, which is why designers typically pick the 80-pin variants over the 64-pin PIC18F66K90 family members when the application needs more glass real-estate and more touch keys.
Typical applications include battery-powered medical devices such as glucose meters and portable patient monitors, industrial panel meters and process transmitters with LCD readouts, home appliances with segment displays, security keypads with capacitive touch, and consumer devices requiring long battery life combined with on-glass graphics. The CTMU simplifies touch-interface designs by measuring capacitance changes without an external analog front end.
When designing with this part, allocate the lower 16 addresses of Flash for the interrupt vector table and use MPLAB XC8 PRO mode for code-density. For LCD applications, follow Microchip's AN658 LCD fundamentals application note for bias and contrast resistor selection, and verify that the segment and common pin assignments fit within the 192-segment maximum of the 80-pin package. Industrial users should confirm the 'I' suffix (-40°C to +85°C) versus the 'E' (-40°C to +125°C) variant when targeting harsher environments.

典型應用
PIC18F86K90-I/PTRSL 適用於 6 應用s: Battery-Powered Medical Meter, Industrial Panel Meter / Process Transmitter, Home Appliance Segment Display, Security Keypad with Capacitive Touch, Portable Consumer Device with Graphical LCD, Smart Home Sensor Node with Display.
Battery-Powered Medical Meter
The PIC18F86K90-I/PTRSL fits battery-powered medical meters because its nanoWatt XLP™ sleep currents in the nanoamp range extend coin-cell life across multi-year service intervals. The integrated 192-segment LCD driver eliminates an external segment-driver IC and the 12-bit ADC captures measurements from analog sensor front-ends. The CTMU adds reliable capacitive buttons for the user interface without a separate touch controller. At 64MHz/16 MIPS, the device can run measurement DSP, encrypt telemetry, and refresh the LCD without compromising response latency.

Industrial Panel Meter / Process Transmitter
Industrial panel meters benefit from the PIC18F86K90-I/PTRSL's 1.8V-5.5V VDD range, -40°C to +85°C industrial temperature grade, and 4KB RAM that buffers fieldbus protocol stacks such as HART or Modbus. The 192-segment LCD capability supports a 4-digit numeric display plus engineering units and status icons. The CTMU enables sealed-front-panel capacitive keys with no mechanical buttons, improving IP65+ ingress protection. Designers can use MPLAB Code Configurator to spin up UART, I²C, and ADC peripherals in minutes.

Security keypads that need PIN entry plus a status display benefit from the PIC18F86K90-I/PTRSL's CTMU, which supports up to 24 capacitive touch channels without an external touch controller. The integrated LCD driver drives 192 segments-enough for a 16-digit PIN pad plus icons for armed, alarm, fault, and battery states. The 8-bit PIC18 core handles AES-style authentication routines in firmware, and nanoWatt XLP™ sleep extends battery life in wireless sensors. The wide 1.8V-5.5V VDD range simplifies battery management.
推薦
Portable Consumer Device with Graphical LCD
Portable consumer devices such as e-bike displays, personal health trackers, and remote controls use the PIC18F86K90-I/PTRSL because it drives the LCD glass, runs the user interface, and reads sensors with a single IC. The 64KB Flash holds firmware graphics, and the 4KB RAM buffers display frames. The 12-bit ADC captures battery voltage and analog sensor data, while multiple UART/SPI/I²C ports connect to Bluetooth or Wi-Fi modules. The wide VDD range supports direct Li-ion battery operation down to 3.0V cutoff.
推薦
Smart Home Sensor Node with Display
Smart-home sensors such as indoor air-quality monitors, thermostat remotes, and energy meters pair the PIC18F86K90-I/PTRSL with a small LCD to surface readings without needing a smartphone app. The CTMU supports touch buttons, the LCD driver displays readings, and the 64KB Flash fits Zigbee or Matter protocol stacks. The 16 MIPS throughput processes sensor data and encryption, while nanoWatt XLP™ sleep enables multi-year battery life on 2xAA cells. The wide 1.8V-5.5V VDD accommodates battery voltage droop without brown-out issues.

設計說明
Estimated: at 64MHz active, the PIC18F86K90-I/PTRSL core draws roughly 8-12 mA from 3.3V, dominated by the LCD driver and I/O switching. In Sleep mode with nanoWatt XLP™ enabled, current drops to under 100 nA typical, allowing multi-year battery life in metering applications. Use the Microchip MPLAB XC8 POWER_DEBUG plugin and AN1414 to characterize your actual application current before committing to a battery chemistry.
Decouple VDD with a 100 nF ceramic placed within 5 mm of each VDD/AVDD pin pair, plus a bulk 10 µF tantalum or ceramic. The LCD driver charge-pump output (VLCD) and bias pins (LCDBIASx) need their own 100 nF capacitors close to the pins per application note AN658. Use a star-ground topology tying AGND to DGND at a single point beneath the IC, and keep the high-frequency MCU traces away from the LCD glass connector.
Do not skip the configuration bits (CONFIG1L-3H) or set the wrong oscillator mode - the device defaults to internal oscillator but defaults may not be optimal for USB or timing-critical peripherals. Verify the Vcap pin (if present in your package variant) has a 10 µF capacitor, and confirm the LCD segment/common pin assignments do not collide with CTMU touch channels when both features are used simultaneously on the same pin. Always check the latest PIC18F87K90 silicon errata (DS80000542) for known anomalies before locking the PCB layout.
When driving longer traces to the LCD glass (typically a 1-3 cm flex cable), add 1-10 kΩ series resistors on each segment line to dampen overshoot from the high-impedance LCD outputs. For CTMU touch channels, keep the touch electrode traces short, guarded by a ground plane, and away from switching signals. The Microchip AN1250 CTMU application note gives PCB layout guidelines for robust capacitive touch sensing.
