PIC18F95J94T-I/PF Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, working RAM, plus peripherals such as timers, ADC, communication controllers and I/O. The PIC18F95J94 belongs to the 8-bit PIC18 hierarchy - the broadest of Microchip's 8-bit lines - within the larger microcontroller -> embedded controller -> semiconductor taxonomy. The "J" suffix indicates the 2.0-3.6V wide-range flash family, and the "95" pin-count code identifies the 100-pin segment that hosts the highest pin count in this family.
Key features include 32KB Flash, 4KB RAM, 16 MIPS throughput, nanoWatt XLP sleep currents typically below 100 nA, an integrated USB 2.0 full-speed transceiver, a 10-bit ADC up to 1.1 Msps, multiple Enhanced USART, SPI and I2C peripherals, and a segmented LCD controller with up to 480 pixels and charge-pump bias. The CTMU module provides capacitive-touch sensing for buttons, sliders and proximity detection without an external touch controller.
The PIC18J core uses a 16-bit modified-Harvard architecture with hardware multiply, an 8x8 hardware multiplier, and C-friendly call frames. The integrated 3.3V LDO and wide 2.0-3.6V supply enable direct Li-ion or 2xAA operation, while the segmented LCD driver with selectable contrast and bias modes (Static, 1/2, 1/3, 1/4) supports up to 48 commons / 112 segments, ideal for human-machine interfaces.
Typical applications include USB human-interface devices (HID) with LCD displays such as industrial remote controls, blood-pressure and glucose meters with segmented LCD readouts, USB smart-card readers, electronic shelf labels, and capacitive-touch user interfaces. The USB + LCD combination is a distinctive pairing for low-cost connected products.
When designing with this device, budget the 32KB Flash and 4KB RAM carefully: 32KB suits small USB stacks (Microchip's USB framework typically consumes 8-14KB) but limits complex graphics. Use the CTMU for touch and the RTCC for calendar functions to keep the main loop lean.

Capacitive-Touch User Interfaces
The PIC18F95J94T-I/PF's on-chip CTMU (Charge Time Measurement Unit) enables capacitive-touch button, slider, and wheel sensing without an external touch controller, reducing BOM cost for appliances, audio equipment, and consumer products. Combined with the integrated segmented LCD (up to 480 segments for status readouts) and 80 I/O pins, the part supports full touch + display interfaces in a 14x14 mm 100-TQFP. nanoWatt XLP below 100 nA sleep is ideal for battery-powered touch remotes; wake-on-touch current draw is microamp-range.
Recommended
Electronic Shelf Labels and Retail Displays
The PIC18F95J94T-I/PF suits small-footprint retail devices - electronic shelf labels (ESL), price-tag updaters, and POS peripherals - with its USB port for in-store programming and segmented LCD (up to 480 segments for price, currency, and barcode) for clear at-a-glance readouts. The 32KB Flash accommodates USB plus ESL update logic, and nanoWatt XLP below 100 nA sleep supports coin-cell or button-cell operation for years. The 100-pin TQFP footprint is shared with the broader PIC18FxxJ94 family, allowing PCB reuse across ESL, labeler, and POS variants.
Recommended
Portable Data-Acquisition Loggers
The PIC18F95J94T-I/PF's 10-bit ADC up to 1.1 Msps, 32KB Flash, 4KB RAM, and integrated USB for data offload make it a fit for portable data loggers - environmental sensors, vibration loggers, and field-test instruments. The segmented LCD (up to 480 segments) shows real-time readings without a graphic-display penalty, and the wide 2.0-3.6V supply supports field-battery operation. nanoWatt XLP below 100 nA sleep enables long standby between measurement bursts; USB Full-Speed provides fast data offload back to the host.

Key Differentiators
- USB Full-Speed + segmented LCD (up to 480 segments) in 32KB Flash (vs PIC18F87J72-I/PT (no USB))
- nanoWatt XLP for years of battery life (vs PIC18F87J10-I/PT (no XLP))
- 100-pin TQFP with 80 I/O and integrated USB + LCD (vs PIC18F85J94-I/PT (80-pin TQFP, ~65 I/O))
Design Notes
The PIC18F95J94T-I/PF operates from 2.0V to 3.6V VDD; place a 100nF decoupling capacitor within 5mm of each VDD/VSS pair, plus a 4.7uF bulk capacitor near the VDD pin closest to the internal 3.3V LDO (pin 10/20 region). Estimated: at 64 MHz active, IDD ~10 mA; in nanoWatt XLP sleep, IDD drops below 100 nA. The internal 3.3V LDO powers the USB transceiver; bypass VUSB (pin 83) with 220nF to VSS.
The 100-TQFP (14x14 mm) package is large for a microcontroller - allocate at least 1.5 oz copper pours under the chip for thermal relief and ground. Keep D+ and D- (pins 80/81) traces length-matched to within 2 mm and 90 ohms differential; route the USB traces on the top layer with a continuous ground plane below. The VBUS pin (82) is 5V-tolerant even though the MCU runs at 3.3V, simplifying host-port integration. Place the 1.5 k pull-up resistor on D+ within 25 mm of the chip.
Common pitfalls with the PIC18F95J94T-I/PF: (1) drawing more than 200 mA total from any VDD/VSS pair without additional bulk capacitors; (2) leaving the MCLR pin floating - tie through a 10k pull-up to VDD with a 100nF cap to VSS for proper reset; (3) forgetting to configure the LCD charge pump before enabling segmented LCD display, which causes ghosting; (4) using RTCC without enabling the secondary SOSC oscillator on RC0/RC1 - RTCC accuracy drops from seconds/month to seconds/day. Per Microchip datasheet DS39975, the CTMU module requires a calibration step before each touch-scan burst.
Layout for the PIC18F95J94T-I/PF should keep the analog AVSS/AVDD pair (pins 22/23) isolated from digital VSS with a single-point connection; this star-grounding prevents digital switching noise from coupling into ADC measurements. Route the secondary SOSC crystal traces (RC0/RC1, pins 44/45) within 5 mm of the chip with a guard ground trace; the 32.768 kHz crystal accuracy is sensitive to capacitive loading. Estimate: ADC SNR at 1 Msps is approximately 60 dB with proper layout, dropping to 50 dB without it.
Compliance Information
