PIC16F19196-E/PT Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a rich set of peripherals. The PIC16F19196 belongs to the broader PIC16F1xxx family, which itself is part of Microchip's 8-bit PIC microcontrollers category, positioned for ultra-low-power (XLP) and battery-friendly designs. Within an embedded system hierarchy it sits beneath application processors and above bare-metal timer ICs, providing deterministic real-time control alongside human-interface and analog signal conditioning.
Key features include eXtreme Low-Power (XLP) operation with a claimed standby current in the nanoamp range (per the manufacturer datasheet), an integrated charge pump that maintains regulated LCD bias even when VDD droops, high-current I/O capable of directly driving LCD backlighting, and battery backup of the on-chip Real-Time Clock/Calendar (RTCC). Additional peripherals include a low-power comparator, PWM, CCP, CWG, SMT (Signal Measurement Timer), ZCD (zero-cross detect), PPS (Peripheral Pin Select), Windowed Watchdog Timer (WWDT), HLT (Hardware Limit Timer), and Peripheral Module Disable (PMD) for power gating unused functions at runtime.
Architecturally, the part uses Microchip's 8-bit modified Harvard core with a 14-bit instruction word, hardware multiplier, and an interrupt controller. The LCD driver supports up to 384 segments with charge-pump bias generation. The 12-bit ADC2 block delivers differential and single-ended conversions with hardware averaging. The RTCC can be retained from a backup coin cell while the main VDD rail is removed, enabling calendar functions across battery swaps.
Typical applications include battery-powered thermostats and HVAC controllers, home-appliance user interfaces with LCD, wearable fitness and medical monitors, e-metering and utility displays, and rugged industrial sensor readouts with LCD. The wide operating temperature and ultra-low standby current also suit automotive aftermarket products and remote IoT endpoints that must run for years on a single cell.
A key design consideration is leveraging the PMD registers to disable peripherals that are not in use, and using the charge pump to keep the LCD contrast constant as VDD discharges. Designers should also plan the PPS routing early, since most digital peripherals can be mapped to multiple pins on this family.

Typische Anwendungen
PIC16F19196-E/PT ist geeignet für 6 Anwendungs: Battery-Powered Thermostat, Home Appliance User Interface (LCD), Wearable Fitness / Health Monitor, Electronic Metering (e-Meter) / Utility Display, Industrial Sensor Readout with LCD, IoT Endpoint / Remote Sensor Node.
Battery-Powered Thermostat
The PIC16F19196-E/PT's eXtreme Low-Power (XLP) sleep current in the nanoamp range, integrated LCD charge pump that holds contrast as VDD decays, and 256 B of EEPROM for setpoint storage make it a natural fit for battery-powered thermostats. The 12-bit ADC2 across 45 channels handles temperature, humidity, and supply-voltage monitoring simultaneously, while the on-chip RTCC keeps wall-clock time across battery swaps. Designers can leverage the PMD register set to gate unused peripherals and stretch coin-cell life into the multi-year range without external analog front-ends.
Empfohlen
Home Appliance User Interface (LCD)
For washing machines, dishwashers, and ovens, the PIC16F19196-E/PT drives up to 384 LCD segments with the integrated charge pump, eliminating the need for an external bias generator. The high-current I/O can source backlight directly through a transistor pair, and the 12-bit ADC2 reads front-panel potentiometers and NTC sensors with hardware averaging. The 59 GPIO handle capacitive touch via the peripheral pin select (PPS) matrix, while PMD disables unused blocks during the standby display state to reduce standby power below typical energy-star targets.
Empfohlen
Wearable Fitness / Health Monitor
The PIC16F19196-E/PT suits wearables thanks to XLP sleep, the 12-bit ADC for heart-rate and SpO2 sensor readouts, and the RTCC backup domain that retains calendar data when the main cell is removed for charging. The 2 KB RAM buffers sensor bursts, while 256 B EEPROM stores user profiles without external memory. Designers can route peripherals via PPS to keep the analog and digital grounds separated on the small PCB, and the -40C to +125C range supports both body-worn and outdoor fitness use cases.
Empfohlen
Electronic Metering (e-Meter) / Utility Display
In e-meters and water/heat meters, the PIC16F19196-E/PT's RTC with battery backup records metering intervals and tariff schedules through power outages. The 12-bit ADC2 captures metrology analog signals from current shunts or thermistors, while the integrated LCD with charge pump delivers readable displays without external boost. The 28 KB Flash accommodates metering firmware, calibration tables, and secure boot routines. PMD selectively disables the LCD or ADC to meet battery-life targets mandated by utility standards.
Empfohlen
Industrial Sensor Readout with LCD
Factory-floor sensor heads benefit from the PIC16F19196-E/PT's industrial -40C to +125C operating range, hardware CIP blocks (SMT, CWG, ZCD) for signal conditioning, and integrated LCD for local status display. The 32MHz CPU executes filter loops while the PMD module parks idle peripherals to reduce heat. The 12-bit ADC with differential inputs accommodates bridge-type pressure and strain sensors, and the EEPROM stores calibration constants on the line.
Empfohlen
IoT Endpoint / Remote Sensor Node
The PIC16F19196-E/PT hosts Core Independent Peripherals that can run sensor sampling, threshold checks, and wake-up sequencing without CPU intervention, perfect for battery-fed IoT endpoints transmitting occasional readings via a companion radio. The LCD can locally display last-known state, while the 256 B EEPROM stores node IDs and credentials. Low-power comparator wake-ups, PMD gating, and the XLP sleep modes enable multi-year battery life on two AA cells, even with periodic LCD refreshes for user feedback.

Wichtigste Unterscheidungsmerkmale
- Highest Flash tier in the 64-TQFP PIC16F1919x family (vs. PIC16F19195-E/PT)
- Integrated LCD charge pump survives VDD droop (vs. PIC16F18877-I/PT)
- Industrial/extended -40C to +125C temperature range (vs. PIC16LF19196-I/PT)
Designhinweise
Estimated: with VDD = 3.3V and XLP sleep mode plus LCD charge pump running at 1 Hz refresh, standby current is typically a few microamps including RTCC backup. Designers must place the VCAP decoupling capacitor (pin 63) within 1-2 mm of the pin to keep the on-chip regulator stable, and configure the PMD register to disable peripherals not in use - turning off the ADC and reference generator in pure-LCD idle states can yield 50-80% standby current savings.
On the 64-TQFP (10x10 mm) layout, dedicate a continuous ground pour under the MCU and tie VDD/AVDD together at a single ferrite-bead filter if the analog inputs are active, separating analog and digital ground returns only at that ferrite. Place VLCD1 / VLCD2 (pins 61, 62) charge-pump caps immediately adjacent to the IC and route the LCD segment traces with adequate spacing to avoid crosstalk - typical Microchip reference designs use 100nF X7R on each VLCD node.
Estimated: a common pitfall is failing to configure PPS (Peripheral Pin Select) before relying on a peripheral on a given pin - if the default pin mapping is changed, the peripheral will silently misroute. Another common mistake is leaving unused analog inputs floating; the datasheet recommends tying them to AVSS or AVDD to prevent shoot-through current. Finally, ensure the MCLR pin (pin 64) is either tied to VDD through a 10k resistor or left as a reset input - never left floating.
