PIC16F19185T-I/PT Visão geral
A PIC microcontroller (Programmable Interface Controller) is a Harvard-architecture 8-bit RISC MCU family from Microchip, used in embedded control from simple timer loops to complex battery-powered instruments. The PIC16F19185 belongs to the PIC16F1 enhanced mid-range family, positioned between baseline PIC10/12/16 and the higher-end PIC18F/dsPIC33 lines. Within Microchip's product hierarchy, this device is classified as an MCU -> 8-bit MCU -> PIC16 family -> PIC16F191xx sub-family, targeting ultra-low-power LCD applications that combine eXtreme Low-Power (XLP) technology with intelligent analog and configurable logic.
Key features include a Charge Time Measurement Unit (CTMU), a 12-bit ADC with computation (ADC2), up to 43 high-current I/O capable of 50 mA source/sink for direct LED drive, hardware Capacitive Touch support, and an integrated LCD driver with charge pump that can bias glass even from a single-cell Li-ion supply. The device provides multiple power-managed operating modes (RUN, DOZE, IDLE, SLEEP) with sub-uA SLEEP current and a rapid wake-up time.
Architecturally, the PIC16F19185 uses a 14-bit instruction word with a 16-level hardware stack and an 8-bit data path, backed by the NanoWatt XLP power management block. The 14KB Flash (8K x 14) supports self-programming, and 1KB SRAM plus 256B data EEPROM provides ample storage for sensor calibration, LCD segment maps, and user settings.
Typical applications include battery-powered LCD thermostats, low-power sensor hubs with on-glass display, water/gas meters with integrated charge pump, capacitive-touch control panels with LCD feedback, and portable medical monitoring devices that require long battery life and visual feedback.
When designing with this device, choose the -I industrial grade for commercial products and -E extended grade for harsher environments. Ensure decoupling follows the Microchip PICDEM and Curiosity HPC kit reference layouts, and that the charge pump capacitors match the LCD glass specifications.

Aplicações típicas
PIC16F19185T-I/PT é adequado para 6 aplicaçãos: Battery-Powered LCD Thermostats, Low-Power Sensor Hubs with On-Glass Display, Water and Gas Meters with Integrated Charge Pump, Capacitive Touch Control Panels with LCD Feedback, Portable Medical Monitoring Devices, Industrial IoT Edge Nodes with Visual Display.
Battery-Powered LCD Thermostats
The PIC16F19185T-I/PT's integrated LCD charge pump maintains glass contrast as the battery drops below 3V, while sub-uA SLEEP current extends coin-cell life to multiple years. With 14KB Flash and CTMU support, the MCU can run a PID control loop, read NTC thermistors through ADC2, and drive a 4-MUX LCD segment display directly. Designers place the MCU on a 2-layer FR-4 board with a 32.768 kHz crystal for RTC timing and use the integrated charge pump to bias the LCD without external capacitors larger than 1 uF, saving BOM cost.
Recomendado
Low-Power Sensor Hubs with On-Glass Display
The PIC16F19185T-I/PT's NanoWatt XLP modes draw under 1 uA in SLEEP while the LCD charge pump keeps the segment display readable, making it ideal for solar-recharged sensor hubs reporting temperature, humidity, and CO2. The MCU wakes on timer interrupt, samples ADC2 channels with hardware averaging, updates the LCD via the integrated segment driver, and returns to SLEEP. With 1KB SRAM and the CLC peripheral, designers can implement glue logic without external gates, simplifying the BOM for industrial IoT edge nodes.
Recomendado
Water and Gas Meters with Integrated Charge Pump
The PIC16F19185T-I/PT's built-in charge pump biases an LCD glass from a single 3V lithium cell, eliminating the discrete boost converter that legacy metering designs require. With CTMU for capacitive flow sensing, ADC2 for analog pressure inputs, and 256B EEPROM for tariff storage, the MCU can run a 20-year gas meter on a single battery. The 32 MHz core provides ample MIPS for encryption and tamper detection, while the XLP SLEEP current keeps idle draw to under 1 uA between flow pulses.
Recomendado
Capacitive Touch Control Panels with LCD Feedback
The PIC16F19185T-I/PT integrates CTMU hardware for capacitive touch sensing plus an LCD driver, enabling a single-chip touch panel with on-glass status icons for white goods and industrial HMIs. With 50 mA source/sink capability on up to 43 I/O, the MCU can directly drive LED backlights and relay coils without external drivers, while the 14KB Flash holds mTouch firmware libraries and custom UI logic. The 32 MHz core executes touch scans and LCD refresh with deterministic latency, avoiding display flicker.
Recomendado
Portable Medical Monitoring Devices
The PIC16F19185T-I/PT's IEC 60730 Class B diagnostic libraries, combined with sub-uA XLP sleep and an integrated LCD charge pump, suit portable medical devices such as pulse oximeters and blood-pressure cuffs that must display readings on glass for months on a single battery. The MCU's 12-bit ADC2 with computation oversamples sensor signals for noise-free SpO2 readings, while the CLC peripheral implements safety interlocks without external logic. Operating from 3.0V to 5.5V supports both 3V coin cells and 4xAA packs.
Recomendado
Industrial IoT Edge Nodes with Visual Display
The PIC16F19185T-I/PT powers industrial edge nodes that show sensor counts, error codes, and connection status on a local LCD without a wireless link. The MCU's NCO and PWM peripherals can modulate LoRaWAN or Sub-GHz OOK signals while the integrated charge pump keeps the LCD visible in cold (-40C) outdoor enclosures. The 256B EEPROM retains calibration data across power cycles, and the XLP power modes let the device survive on harvested energy with sub-uA quiescent draw.

Principais diferenciais
- Integrated LCD charge pump with 4-MUX capability in 48-TQFP (vs PIC16F18877-I/PT)
- CTMU hardware capacitive touch controller on-chip (vs PIC16F18876-I/P)

Notas de projeto
Estimated: at VDD=5V driving the LCD charge pump with a 4-MUX glass, the PIC16F19185T-I/PT typically draws 200-400 uA active. SLEEP current with RTCC and LCD charge pump running is 1-2 uA per the NanoWatt XLP datasheet section. Place a 1uF X7R bypass within 5 mm of every VDD pin pair, and use a low-ESR bulk capacitor on the charge pump output to avoid LCD contrast ripple.
The 48-TQFP exposed thermal pad (EP) must be soldered to a contiguous ground pour of at least 100 mm^2 for thermal relief; otherwise the die can overheat in sealed enclosures. Route the LCD segment lines on the top layer only to avoid cross-talk from the ADC analog inputs, and keep the VSS return path short by stitching vias around the EP. Follow the Microchip PICDEM Curiosity HPC layout as a reference for two-layer designs.
Do not enable the LCD charge pump below 2.5V VDD without verifying your glass specifications - the charge pump will draw extra current and may not reach the programmed voltage. Always configure the ADC2 channel in the ANSEL register before reading, or the digital input buffer fights the analog signal and corrupts the conversion. Also remember that RE3 on PIC16F19185 is input-only - never drive it as an output.
When using CTMU for capacitive touch, route the CPS lines away from switching signals and add a 10 nF guard ring tied to a quiet analog ground; this improves touch SNR by 10-15 dB on Microchip evaluation boards. Avoid sharing ADC analog channels with digital outputs to prevent crosstalk during the 12-bit acquisition window.
