PIC18F67J93T-I/PT Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, volatile data memory, and a rich set of peripherals such as timers, ADC, communication interfaces and I/O ports on a single silicon die. Within the broader taxonomy, the PIC18F belongs to the PIC family -> 8-bit RISC microcontrollers -> microcontrollers (MCUs) -> embedded controllers -> semiconductors. The 'F' denotes Flash program memory, allowing in-system re-programmability without an external ROM. The integrated LCD driver up to 128 segments and the ultra-low-power nanoWatt technology make this sub-family ideal for battery-powered graphical or alphanumeric display products.
Key features include 51 usable I/O pins, 16 MIPS throughput, a 12-bit A/D converter capable of 12 input channels, multiple Enhanced USART, SPI and I2C interfaces, an integrated LCD module with charge pump, and nanoWatt power management that drops quiescent current below 1 µA in sleep mode. The PIC18 Harvard architecture provides deterministic instruction timing and a rich C-optimized instruction set, while the 16-bit-wide instruction word preserves code density close to 16-bit cores.
Typical applications span handheld utility meters, electronic thermostats, home-security panels, portable medical monitors, and industrial control panels where segmented LCD displays and capacitive touch replace mechanical keypads. Wide -40 °C to +85 °C industrial operating range plus nanoWatt idle modes let the same silicon target both line-powered and battery-powered enclosures. The 64-pin TQFP industrial-temperature grade (-I) and tape-and-reel ('T') packaging make it equally at home on a hand-repair bench or in a high-volume SMT line.
When designing with this part, ensure the VDD/VSS supply decoupling follows the datasheet typical application circuit - one 0.1 µF ceramic close to each VDD/VSS pair, and a bulk 4.7 µF to 10 µF tantalum or ceramic on the main rail. Use the internal regulator only after confirming the VDDCORE pin has its own 10 µF + 0.1 µF bypass network. For LCD designs, drive segment lines with a 1 kHz to 200 Hz frame frequency and check the bias network resistors per the LCD voltage reference configuration.

Aplicações típicas
PIC18F67J93T-I/PT é adequado para 6 aplicaçãos: Handheld Utility Meter, Electronic Thermostat, Home Security Keypad Panel, Portable Medical Monitor, Industrial Control Panel HMI, Battery-Powered Weighing Scale.
Handheld Utility Meter
Why this fits: The PIC18F67J93T-I/PT's integrated segmented LCD driver (up to 128 segments) and 128 KB Flash let a single chip drive the 7-segment consumption display, store metering history, and run the CTMU-based tamper detection loop without an external LCD bias IC. The 2.0 V to 3.6 V wide voltage range accommodates two AA cells in series plus a low-dropout regulator with margin for end-of-life brownout. How it is used: The MCU reads the meter's pulse output through the 12-bit ADC, multiplies by calibration coefficients, and refreshes the LCD at 60 Hz. Compared to discrete driver solutions, the 'J93 eliminates the external charge pump and segment drivers, reducing BOM cost by ~30 % and PCB area by ~20 %.
Recomendado
Electronic Thermostat
Why this fits: The 12-bit ADC on the PIC18F67J93T-I/PT delivers 0.81 mV resolution at 3.3 V full scale, enough to read 10 kΩ NTC thermistor networks to within ±0.1 °C after linearization. The on-chip LCD peripheral displays room temperature, set-point and scheduling without external drivers, while the nanoWatt idle modes drop quiescent current below 1 µA in standby, which is critical for battery-backed thermostats. How it is used: The MCU periodically wakes from sleep, samples the thermistor bridge, drives the relay, and updates the LCD. Compared to a Cortex-M0 + external LCD ASIC solution, the PIC18F67J93 saves roughly USD 1.20 per board and simplifies FCC certification thanks to lower radiated emissions from the slower 48 MHz core.
Recomendado
Home Security Keypad Panel
Why this fits: The CTMU peripheral of the PIC18F67J93T-I/PT enables up to 12 capacitive touch buttons with no external touch IC, while the LCD driver shows the 16-digit PIN entry and arm/disarm status on a single chip. The 51 usable I/O pins leave plenty of headroom for indicator LEDs, a piezo buzzer, and an encrypted serial link to the main panel. How it is used: The MCU scans the CTMU-driven touch matrix at 100 Hz, debounces in firmware, and updates the LCD. Compared to mechanical-membrane keypads with a separate LCD driver, the capacitive design improves ingress protection and eliminates mechanical wear, extending the product's MTBF by roughly 3x.
Recomendado
Portable Medical Monitor
Why this fits: The PIC18F67J93T-I/PT's 128 KB Flash is large enough to hold a medically-certified firmware image plus a USB bootloader for in-field updates. The 12-bit ADC reads SpO2, pulse-rate and battery voltage signals, while the integrated segmented LCD displays readings without backlight flicker. The -40 °C to +85 °C industrial range ensures operation in ambulances and cold-storage facilities. How it is used: The MCU sequences the analog front-end, performs SpO2 ratiometric calculations, and refreshes the LCD at 50 Hz. Compared to a discrete 8051 + LCD module design, the PIC18F67J93 reduces firmware development time by ~40 % thanks to MPLAB Harmony and the proven PIC18 instruction set.
Recomendado
Industrial Control Panel HMI
Why this fits: The 64-pin TQFP footprint and 51 I/O pins of the PIC18F67J93T-I/PT give industrial HMI designers enough GPIO to drive status LEDs, multi-drop RS-485 transceivers and a segmented LCD simultaneously. The wide -40 °C to +85 °C industrial temperature grade plus 16 MIPS throughput comfortably run a real-time operator interface loop with sub-10 ms latency. How it is used: The MCU scans front-panel buttons, refreshes the LCD every 50 ms, and services the RS-485 link to a PLC. Compared to a 32-bit ARM Cortex-M0 design at the same BOM cost, the PIC18F67J93 trades raw MIPS for deterministic interrupt latency and ultra-low idle power, which suits solar-powered field installations.
Recomendado
Battery-Powered Weighing Scale
Why this fits: The CTMU and 12-bit ADC of the PIC18F67J93T-I/PT let a load-cell signal chain run on the chip alone, while the integrated LCD peripheral displays weight, tare and unit. The 2.0 V to 3.6 V wide voltage range is ideal for 2xAA cells, and the nanoWatt idle modes drop quiescent current below 1 µA so a retail scale can sit on the shelf for years without battery replacement. How it is used: The MCU excites the load cell, digitizes the differential signal, applies calibration, and refreshes the LCD. Compared to a 24-bit sigma-delta ADC + 8-bit controller design, the PIC18F67J93 reduces analog-front-end cost by ~USD 0.80 while meeting 0.05 % measurement accuracy after software compensation.

Notas de projeto
Place one 0.1 µF ceramic decoupling capacitor as close as physically possible to every VDD/VSS pair on the PIC18F67J93T-I/PT, plus a single bulk 4.7 µF to 10 µF tantalum or ceramic on the main 3.3 V rail. The internal 2.5 V regulator on the VDDCORE pin MUST have its own dedicated 10 µF + 0.1 µF bypass network; failure to do so results in brownout during Flash programming operations. The 'J93 nanoWatt sleep current of <1 µA assumes AVDD is tied to VDD - any separate analog supply must be sequenced or diode-protected.
Route the LCD segment and common lines on the outer PCB layers with at least 0.2 mm trace clearance and route them away from switching power and digital bus lines to minimize coupling. The on-chip LCD charge pump generates a high-impedance bias voltage; keep the bias capacitor within 5 mm of the LCD bias pins. Use a ground pour under the TQFP exposed pad and stitch vias on a 2 mm pitch around the package perimeter to reduce radiated emissions from the 48 MHz core.
Do not confuse the 'T' suffix on the MPN (which denotes tape-and-reel packaging, not a different pinout) with the 'T' in the package code 'PT'. The PIC18F67J93T-I/PT and PIC18F67J93-I/PT share identical silicon and pinout - only the carrier format differs. Similarly, the 'J' family operates ONLY at 2.0 V to 3.6 V; do not connect a 5 V supply or program the device at 5 V - this is a common trap when migrating from the legacy PIC18F6722 design.
The CTMU peripheral of the PIC18F67J93T-I/PT produces very small currents (typ. 0.55 µA) for capacitive touch sensing; long PCB traces on CTMU-capable pins pick up mains hum and degrade touch accuracy. Keep CTMU traces under 50 mm and shield them with a ground pour. For multi-layer boards, route CTMU traces on the top layer only and reference to an unbroken ground plane on layer 2.
