MPN: PIC16LF19196-E/PT ✓ Hoạt độngPIC16LF19196-E/PT Tóm tắt
An 8-bit PIC microcontroller is a RISC-based, Harvard-architecture embedded processor that executes one instruction per clock cycle (except branches) and is positioned in Microchip's product hierarchy as PIC -> PIC16 -> PIC16F19xx -> XLP family. The 'LF' in the part number indicates the low-power F-version core, which supports lower Vdd operation than the standard F variant, while 'XLP' (eXtreme Low Power) is Microchip's branded low-power technology family targeting battery-powered and energy-harvesting designs. The integrated charge pump and high-current I/O make this sub-family especially suited for battery-powered LCD applications where discrete LCD bias generation would otherwise inflate BOM cost.
Key features include a 12-bit ADC with computation (ADC2), a 5-bit/10-bit DAC, low-power comparators (LP COMP), PWM, CCP, CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), ZCD (Zero-Cross Detect), Peripheral Pin Select (PPS), RTCC (Real-Time Clock Calendar), Hardware Limit Timer (HLT), Windowed WWDT, and PMD (Peripheral Module Disable). The 32 MHz internal oscillator plus integrated LCD driver (up to 288 segments) make this part well suited for low-power graphical or segment LCD products.
Technical depth: the LF core operates from 1.8 V to 3.6 V (down to 1.8 V at 16 MHz, 2.5 V to 3.6 V at 32 MHz) with a typical sleep current in the nanoampere range thanks to XLP technology. The 12-bit ADC2 provides automated averaging, accumulation and threshold comparison without CPU intervention (CIP), freeing the core for power management tasks. PPS allows most digital peripherals to be remapped to a wide selection of I/O pins, simplifying PCB routing on densely-populated 64-pin designs.
Typical applications include battery-powered medical devices, industrial sensor transmitters, IoT edge nodes, home-automation HMI panels, smart thermostats, and low-power metering. The integrated LCD driver makes it especially attractive for appliances and instruments with segment displays. Design consideration: pair the MCU with a CR2032 or two AA cells via a boost regulator to leverage XLP sleep currents below 1 uA; verify LCD contrast across temperature and confirm PPS mapping for all peripherals during firmware bring-up.

Ứng dụng tiêu biểu
PIC16LF19196-E/PT phù hợp cho 7 Áp dụngs: Battery-Powered LCD Thermostat, Industrial Sensor Transmitter, IoT Edge Node with Segment LCD, Home-Automation HMI Panel, Low-Power Metering (Water/Gas/Heat), Medical Monitoring Device, Appliance User Interface.
Battery-Powered LCD Thermostat
The PIC16LF19196-E/PT is an ideal fit for battery-powered LCD thermostats because its XLP technology delivers sub-1 uA sleep currents while the integrated LCD driver supports up to 288 segments without an external charge pump or bias network. The 12-bit ADC2 with computation provides accurate temperature sensing directly from a thermistor or RTD, while the RTCC keeps wall-clock time across years on a CR2032 cell. Engineers can use the CWG and PWM peripherals to drive a piezo buzzer or triac for HVAC load switching, and the Hardware Limit Timer protects against relay welding. Compared with discrete LCD + MCU solutions, the 19196 cuts BOM cost by 20 to 30 percent and PCB area by roughly half.

Industrial Sensor Transmitter
For 4-20 mA or wireless HART sensor transmitters, the PIC16LF19196-E/PT delivers the analog density needed in a compact 64-TQFP footprint, with 12-bit ADC2 (computation), 5/10-bit DAC for loop current setting, and low-power comparators for sensor health monitoring. Its -40C to +125C extended temperature grade (E suffix) handles outdoor or process-plant environments, while PPS lets the designer route UART, SPI, and I2C to convenient PCB locations. XLP sleep below 1 uA enables multi-year operation from intrinsic-safe battery packs. The PMD module can selectively shut down peripherals to extend battery life when the loop is unpowered.

IoT Edge Node with Segment LCD
The PIC16LF19196-E/PT is well suited to IoT edge nodes that need a low-power MCU plus an integrated segment-LCD for local status display, eliminating a dedicated LCD driver IC. The 32 MHz core can drive a LoRa, Sub-GHz, or BLE radio over SPI while the CIP peripherals handle background sensor scanning with zero CPU load. ZCD and CWG simplify mains-zero-cross switching for dimmer or smart-plug integration, while SMT allows precise time-of-flight measurements for ultrasonic or capacitive touch. The combination of XLP sleep, integrated LCD, and rich analog makes this part a Swiss-army-knife for connected sensor products.

Home-Automation HMI Panel
For wall-mounted HMI panels with segment LCDs and capacitive touch, the PIC16LF19196-E/PT provides a single-chip solution: integrated LCD driver for the segment display, low-power comparators for capacitive touch sensing via CVD, PWM for backlight dimming, and UART/SPI/I2C for talking to a host controller or wireless module. The 64-TQFP package gives generous I/O (59 pins) to drive multiple keys, LEDs, and a rotary encoder without external logic. PPS simplifies routing on dense HMI boards, while the RTCC handles real-time scheduling without external components.

Low-Power Metering (Water/Gas/Heat)
The PIC16LF19196-E/PT fits battery-powered metering applications where multi-year battery life and a local segment-LCD readout are mandatory. The RTCC accurately timestamps consumption events, while the SMT peripheral enables ultrasonic or magnetic flow-sensor pulse timing with microsecond resolution. Low-power comparators detect tamper events, and the CWG can drive a piezo sounder for alerts. At 32 MHz and 3.3 V, the part can compute complex tariff logic between pulses, then drop to sub-1 uA XLP sleep for the rest of the time, exceeding the 10+ year battery life target required by metering standards.

Medical Monitoring Device
For portable medical monitors such as pulse oximeters, blood-pressure cuffs, or glucose meters, the PIC16LF19196-E/PT's XLP technology, integrated 12-bit ADC2, and -40C to +125C extended temperature range make it a strong fit. The DAC and low-power comparators support sensor excitation and signal conditioning, while the LCD driver displays readings without a separate LCD controller. RTCC logs measurement timestamps, and the Hardware Limit Timer enforces safety timing on actuator or alert channels. Engineered with IEC 60730 Class B libraries available from Microchip, this MCU can accelerate functional-safety compliance for home-health devices.

Appliance User Interface
White-goods appliances (washing machines, ovens, dishwashers) benefit from the PIC16LF19196-E/PT's integrated LCD, CIP peripherals, and extended temperature grade. The 12-bit ADC2 reads multiple sensor channels for temperature, water level, and motor current, while PWM and CWG drive triac-controlled loads without external logic. PMD lets unused peripherals be shut down to save power in standby. The -40C to +125C range handles the thermal stress of appliance environments, and the 64-TQFP footprint simplifies integration into a control board that also hosts a higher-performance host MCU.

Ghi chú thiết kế
Estimated: at Vdd=3.3 V, 32 MHz active mode and all peripherals enabled, the PIC16LF19196-E/PT draws approximately 4 to 6 mA (datasheet figure). For battery designs, use Sleep mode with RTCC to drop current below 1 uA, and gate the LCD charge pump off when the display is blanked. Always place a 100 nF decoupling capacitor within 5 mm of Vdd and a 10 uF bulk capacitor near the IC to support LCD charge-pump load transients.
The 64-TQFP package has a thermal resistance of approximately 50 C/W (theta_JA) on a 2-layer JEDEC test board, per the Microchip package thermal data. At 6 mA active current and 3.3 V supply the dissipation is roughly 20 mW, well within limits. However, if the LCD charge pump drives a high-segment-count display at maximum bias, derate operating temperature or add a small copper heatsink area on the PCB beneath the exposed pad footprint region (where present).
Route the VLCD1/VLCD2/VLCD3 charge-pump output capacitors as close to the IC as possible to minimise ripple on the LCD bias rails, which directly affects display contrast and ghosting. Keep the COM and SEG traces short and matched in length, and provide a ground pour under the LCD side of the IC. Place the 32.768 kHz crystal within 5 mm of OSC1/OSC2 with a guard ring to reduce noise coupling into the RTCC.
Do not exceed the 3.6 V absolute maximum on Vdd even briefly; the LF variant has no 5 V tolerance and a brownout will not protect against transients above 3.6 V. Always enable the BOR (Brown-Out Reset) in the configuration bits to guarantee a known startup state after a low-battery event. If migrating from PIC16LF19195 firmware, verify that the device ID is updated in the project header so the programmer selects the correct memory map.
When using the 12-bit ADC2 to read low-level analog signals, disable digital inputs on shared analog pins via the ANS register to reduce crosstalk. Average multiple ADC2 conversions using the ADC2 computation engine for higher effective resolution. Place a small RC filter (10 ohm + 100 nF) on noisy analog sources, and avoid routing high-frequency digital lines adjacent to the analog traces on the PCB.
