PIC18F95J94-I/PT - 8-bit USB/LCD MCU 64MHz 32KB FLASH | Microchip
MPN: PIC18F95J94-I/PT ✓ AktifPIC18F95J94-I/PT Ringkasan
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path. As a member of the broader microcontroller category and the wider PIC18 family, the PIC18F95J94 sits inside the Microchip PIC® XLP™ (eXtreme Low Power) line, which targets ultra-low sleep current for battery-powered designs. This device specifically combines a full-speed USB 2.0 peripheral and a segmented LCD driver (up to 480 segments) on-chip - making it a hybrid communication + display MCU, which is rare in the 8-bit space.
Key features include nanoWatt XLP sleep currents as low as the datasheet's spec range, an integrated 12-bit ADC (according to the family datasheet), multiple timers, two SPI/I2C and two UART peripherals, a real-time clock calendar (RTCC) module, and a CTMU charge-time measurement unit for capacitive touch. The 100-TQFP exposes up to 84 I/O lines, supporting large parallel buses or many segmented LCD pixels.
Typical applications include USB human interface (HID) peripherals such as thermostats, blood-pressure monitors and glucose meters with LCD, industrial segment-LCD control panels with USB diagnostics, eMetering / smart-sensor front-ends, and any battery-powered product combining a display and a USB charging or data port.
When designing with this part, ensure the 2.5V to 3.6V VDD range is respected (the J-family runs from a single 3.3V rail, not 5V), provide a stable 12 or 24 MHz crystal for USB Full-Speed operation, and reserve proper bypass capacitors on AVDD/VDD pairs to keep the ADC noise floor low.

Aplikasi Umum
PIC18F95J94-I/PT cocok untuk 6 aplikasis: USB Thermostat with Segmented LCD, Battery-Powered Blood Pressure Monitor, Industrial Segment-LCD Control Panel, Smart Sensor / e-Metering Front-End, USB HID Medical Input Device, USB Charging Cradle with Diagnostic LCD.
USB Thermostat with Segmented LCD
The PIC18F95J94-I/PT's combination of on-chip USB Full-Speed and a segmented LCD driver (up to 480 segments per the family datasheet) is purpose-built for USB-connected thermostats. Its 64MHz CPU provides enough throughput for USB HID stack plus a responsive UI update loop, and nanoWatt XLP technology keeps sleep current low so a thermostat can run for years on battery-backed power. Using the internal LCD charge pump eliminates the negative bias LDO normally needed for 3V LCDs, reducing BOM cost. Connect a USB-C receptacle directly to the D+/D- pins for HVAC service-port diagnostics. With 32KB code space it comfortably fits HVAC control logic plus a USB bootloader.

Battery-Powered Blood Pressure Monitor
Portable medical monitors like blood-pressure cuffs benefit from the PIC18F95J94-I/PT's nanoWatt XLP sleep mode (typical sleep current in the nanoamp range per Microchip XLP datasheets), integrated segmented LCD for the pressure/gauge display, and USB for charging/data. The MCU's 12-bit ADC combined with an analog pressure transducer provides the resolution needed for accurate systolic/diastolic readings, while the RTCC tracks time-of-day measurement history. A 32KB code budget covers the oscillometric algorithm and LCD UI without external memory, and the 100-pin TQFP gives plenty of GPIO for keypad, pump control and buzzer.

Industrial Segment-LCD Control Panel
Industrial control panels with multi-line segment displays need both LCD segment drive and a way to upload firmware or send diagnostics - the PIC18F95J94-I/PT provides both on-chip, plus 100 pins for digital I/O to interface with sensor arrays, relays and communication PHYs. The 2.0V-3.6V VDD range is ideal for 3.3V industrial backplanes. The 100-pin TQFP offers 84 I/O lines, sufficient to drive a 7-segment x 16-digit status display plus 32 GPIOs for HMI buttons, status outputs and an RS-485 transceiver. The same-die drop-in to PIC18F96J94-I/PT provides 64 KB code space for complex SCADA-style firmware without changing the PCB layout.

Smart Sensor / e-Metering Front-End
Electricity, water or gas meters with segmented LCDs and a USB diagnostic port are an ideal target for the PIC18F95J94-I/PT. Its 12-bit ADC, internal LCD segment driver, and USB Full-Speed peripheral enable a single-chip design that eliminates the usual separate LCD controller and USB interface IC. With nanoWatt XLP sleep currents in the nanoamp range, the MCU contributes negligible battery drain during the long sleep phases typical of metering applications, while the 64MHz CPU wakes in microseconds to take a measurement. The 100-pin TQFP gives generous analog-input multiplexing for voltage and current sensing.

USB HID Medical Input Device
Custom USB HID medical input devices such as measurement wands, glucose meters and physical-therapy controllers combine a button or touch interface, a small segment display, and USB - all features natively integrated in the PIC18F95J94-I/PT. The PIC18F95J94's on-chip USB peripheral supports HID, CDC and vendor classes, while the CTMU peripheral enables capacitive-touch buttons without external controller ICs. The internal segmented LCD driver displays measurement results without an external charge pump, reducing BOM to MCU + sensor + battery. 32 KB FLASH is sufficient for the USB stack plus a responsive UI.

USB Charging Cradle with Diagnostic LCD
Crade-style chargers that also display battery state, charge time, or diagnostic status via segmented LCD are a strong fit for the PIC18F95J94-I/PT. The MCU coordinates charge management (via MCP73831 or equivalent), reads battery voltage through its 12-bit ADC, drives a segmented LCD to show state-of-charge, and exposes a USB diagnostic port for service technicians. Industrial -40C to +85C temperature grade ensures operation in automotive and outdoor charging environments. The 32 KB FLASH is enough for charge-profiling algorithms and a UI; upgrade to PIC18F96J94-I/PT (64 KB) for smart-charge curve programming.

Catatan Desain
The PIC18F95J94-I/PT operates from a single 2.0 V to 3.6 V VDD - the 'J' family is NOT 5V tolerant like older PIC18F 'K' parts. Use an MCP1700 low-IQ LDO to derive 3.3V from a USB VBUS or battery source. For battery applications, ensure the LDO's quiescent current is below the MCU's nanoWatt XLP sleep current (typically hundreds of nA) or the LDO becomes the dominant drain.
USB Full-Speed operation requires a 48 MHz system clock, normally derived from a 12 MHz or 24 MHz crystal through the internal PLL. A common pitfall is forgetting to configure the PLL configuration bits in the CONFIG1 register - the firmware will enumerate at low speed or fail to enumerate at all. Use MPLAB X IDE's Configuration Bits window to set PLL enable and divisor, and confirm with a USB analyzer.
Route USB D+/D- as a 90 ohm differential pair with matched impedance, and place the 33 ohm series damping resistors within 5mm of the MCU D+/D- pins. AVss must be tied to Vss at a single point near the MCU - separate analog and digital grounds but connect them at the MCU's AVss pin only. Place 100 nF decoupling on every VDD/VSS pair and a 10 uF bulk on the main VDD pin.
When using the segmented LCD driver, avoid running high-frequency digital traces parallel to the LCD segment lines, especially in COM-heavy areas. Use the LCD charge-pump mode (enabled via firmware) instead of relying on Vdd to derive VLCD - the internal charge pump provides stable VLCD even as battery discharges, which prevents LCD ghosting at low battery voltage. Add a 1uF X7R bypass cap on the VLCD pin.
