PIC18F67K90T-I/MR 概要
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash), data memory (RAM), and peripherals on one die. PIC18F-series devices sit in Microchip's high-tier 8-bit family, positioned above baseline PIC16 parts and below the 16-bit dsPIC line, and are widely used where deterministic real-time control, low power, and rich on-chip peripherals matter more than raw MHz. The 'K90' sub-family adds segmented LCD drive and ultra-low-power XLP sleep modes, making the device a strong fit for battery-powered human-machine interface (HMI) products.
Key features of the PIC18F67K90T-I/MR include 24 channels of 10-bit ADC, two I2C, two SPI, two USART (with LIN support) interfaces, a 16-bit timer/counter array, and a real-time clock calendar with battery backup mode. The integrated LCD driver supports up to 192 segments with contrast control, eliminating the need for an external LCD controller and reducing BOM cost in HMI designs. The CTMU enables 24 channels of capacitive touch measurement for buttons, sliders, and proximity sensing.
Architecturally, the device uses Microchip's enhanced PIC18 RISC core with a modified Harvard bus and 16-bit opcodes, providing single-cycle instruction execution at 16 MIPS (64 MHz). Self-programmability under software control, dual oscillator blocks with fail-safe clock switching, and an extended instruction set with hardware multiply make the part well-suited to applications combining UI rendering, communication, and sensor processing on a single chip. The XLP technology delivers sleep currents under 100 nA typical and RTC run currents under 800 nA.
Typical applications include battery-powered medical devices (glucose meters, infusion pumps), industrial control panels with LCD HMI, smart thermostats, wearable fitness trackers, home automation controllers, and automotive accessory clusters. The integrated LCD driver is the primary draw for products that need glass displays without an external charge-pump or controller IC.
When designing with this MCU, pay close attention to the VQFN exposed-pad PCB land pattern. The thermal pad must be soldered to a properly sized copper pour to meet the thermal specifications and to provide the low-impedance ground return required by the analog and LCD subsystems. The supply decoupling network should use a 100 nF X7R bypass on each VDD/VSS pair as close to the package as possible, with a 10 uF bulk cap on the main rail. A high-precision external 32.768 kHz crystal is recommended when using the RTC calendar function.
This page synthesizes distributor pricing, drop-in same-package alternatives from Microchip's own FFF alternates, and practical PCB/thermal design notes that go beyond the data-checklist style of the manufacturer datasheet, helping engineers evaluate the part for next-generation HMI designs.

主な用途
PIC18F67K90T-I/MR の用途: 6 件s: Battery-Powered Medical Meter, Industrial HMI Control Panel, Smart Thermostat, Wearable Fitness Tracker, Home Automation Controller, Automotive Accessory Cluster.
Battery-Powered Medical Meter
The PIC18F67K90T-I/MR is a strong fit for battery-powered medical meters such as glucose, INR, and HbA1c analyzers. Its 192-segment integrated LCD driver removes the need for an external charge-pump or controller IC, while nanoWatt XLP sleep currents below 100 nA extend coin-cell life. The 24-channel CTMU enables sealed touch keypads that survive repeated disinfection, and the wide 1.8 V to 5.5 V supply range supports direct connection to two AA or single Li-ion cells without boost circuitry.
おすすめ
Industrial HMI Control Panel
For industrial HMI panels, the PIC18F67K90T-I/MR's 192-segment LCD driver and 24-channel CTMU consolidate the front-panel UI onto a single chip. Two I2C and two SPI ports allow simultaneous connection of a sensor front-end, a non-volatile memory for logging, and a host PLC link. The 64-pin VQFN exposed pad simplifies the board layout for sealed IP65 enclosures, and the 54 I/O pins can drive LED status bars, keypads, and segment indicators in parallel with the LCD glass.
おすすめ
Smart Thermostat
The PIC18F67K90T-I/MR is well matched to smart-thermostat designs that combine a segmented LCD, capacitive touch keys, and a low-power wireless or wired sensor front-end. The 24-channel CTMU handles the touch wheel and buttons, the LCD driver directly addresses the front-panel display, and the 64 MHz core runs the control loop and Modbus/RTU or LIN interface. Sleep mode under 100 nA allows the unit to be battery-backed during AC line dropouts without draining the backup cell.
おすすめ
Wearable Fitness Tracker
For wearable fitness trackers, the PIC18F67K90T-I/MR provides the right balance of low power, integrated display, and capacitive touch. The XLP nanoWatt sleep mode drops current below 100 nA when the display is blanked, while the on-chip LCD charge pump drives the segmented glass directly from the Li-ion cell voltage. The 24-channel CTMU reads the capacitive button and proximity sensor, and the 4 KB RAM holds a few hours of step-count or heart-rate buffer before flush to EEPROM.
おすすめ
Home Automation Controller
The PIC18F67K90T-I/MR is an effective central controller for wall-mounted home automation keypads with LCD readouts. The 54 I/O pins drive relay triacs, zero-cross detectors, and key-scanning matrices, while the 192-segment LCD driver shows temperature, time, and zone status. The two USARTs provide LIN and RS-485, the two I2C buses connect to temperature/humidity sensors, and the wide 1.8 V to 5.5 V supply range allows direct operation from rectified 24 V AC or 5 V DC bus.
おすすめ
Automotive Accessory Cluster
The PIC18F67K90T-I/MR suits automotive accessory clusters such as motorcycle dashboards, RV control panels, and aftermarket gauges. The integrated LCD driver provides sun-readable segmented display, the CTMU handles backlit capacitive touch keys, and the dual USART with LIN support talks to the vehicle bus. For under-hood use, designers should select the E-grade variant (PIC18F67K90T-E/MR) for +125 C operation, keeping the same VQFN-64 MR footprint on the PCB.

設計ノート
The 64-pin VQFN package dissipates heat through the exposed pad. Solder the pad to a copper pour of at least 1 square inch on the top layer, with thermal vias to an internal ground plane. At the full 64 MHz CPU clock with all peripherals active, the typical active current is around 15 mA, giving only modest self-heating, but sealed enclosures with no airflow will see junction temperature rise of 10-15 C above ambient.
Place a 100 nF X7R 0402 bypass capacitor within 2 mm of each VDD/VSS pair, plus a 10 uF X5R bulk on the main 3.3 V rail. A separate 100 nF cap on AVDD/AVSS is required to keep ADC readings within spec. The 32.768 kHz SOSC crystal traces must be short and guarded by a ground ring to avoid coupling the main oscillator's harmonics into the RTC calendar counter.
Route LCD segment lines on a layer that is isolated from switching digital signals. The 192-segment driver is sensitive to cross-talk above 200 Hz; keeping segment traces under a ground shield on the layer below reduces ghosting on the glass. The CTMU channels share the ADC inputs, so guard the analog input traces with a ground pour to preserve capacitive touch sensitivity in noisy environments.
Do not omit the VCAP capacitor on pin 42. The internal voltage regulator requires at least 1 uF low-ESR ceramic on VCAP to maintain core logic integrity. Forgetting this part leads to POR resets and intermittent Flash programming failures. Also confirm the ICSP PGC/PGD pins (RB6/RB7) are not loaded with more than 10 pF of stray capacitance or in-circuit programming will fail.
