PIC16LF19196-E/5LXVAO - 28KB Flash 8-bit XLP LCD MCU | Microchip
MPN: PIC16LF19196-E/5LXVAO ✓ Hoạt độngPIC16LF19196-E/5LXVAO Tóm tắt
A microcontroller is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory (SRAM), and a configurable set of digital and analog peripherals. Within the broader taxonomy, the PIC16LF19196 sits in the PIC16 mid-range family -> 8-bit RISC microcontroller -> MCU -> embedded microcontroller -> semiconductor. Compared with 16-bit or 32-bit Cortex-M parts, an 8-bit PIC16 lowers cost, code complexity, and active current, while still providing enough throughput for sensor hubs, HMI, and battery-powered LCD applications.
Key differentiating features include Microchip's eXtreme Low-Power (XLP) technology with deep-sleep currents below 1 uA, an integrated LCD charge pump that simplifies glass drive from a single lithium cell, and CIP analog blocks such as 12-bit ADC, 5-bit DAC, comparators, and zero-cross detection. The 64-VQFN footprint with exposed pad supports thermally robust layouts for high-current I/O segments and reduces PCB area versus 64-pin TQFP when board real estate is constrained.
On the architecture side, the PIC16LF19196 combines a 14-bit instruction word, a hardware multiplier, and a peripheral pin-select (PPS) engine that allows remapping of digital functions to optimize PCB routing. The 32MHz oscillator with 4x PLL equivalent provides deterministic interrupt latency critical for motor control loops, while the integrated charge pump and high-current I/O eliminate external DC-DC and segment-driver components in LCD user interfaces.
Typical applications include battery-powered LCD thermostats, IoT sensor nodes with always-on displays, automotive dashboard indicators, medical infusion pumps, metering and instrumentation with segment LCDs, and ultra-low-power HMI keypads. The combination of XLP sleep current and integrated LCD drive makes the part especially attractive for products that need years of coin-cell life with a live alphanumeric or graphical segment display.
When designing with this part, ensure the exposed pad is soldered to a sufficient copper pour (at least 1 square cm) so junction temperature stays within the -40C to +125C automotive range under full I/O loading. The PPS feature should be assigned early in the schematic to avoid pin-function conflicts in the 64-VQFN footprint, and unused pins must be tied to defined logic states (not left floating) for robustness in AEC-Q100 systems.

Ứng dụng tiêu biểu
PIC16LF19196-E/5LXVAO phù hợp cho 6 Áp dụngs: Automotive LCD Instrument Cluster, Battery-Powered Smart Thermostat, Medical Infusion Pump HMI, IoT Sensor Node with Segment LCD, Industrial HVAC Controller, Smart Meter and Utility Display.
Automotive LCD Instrument Cluster
The PIC16LF19196-E/5LXVAO is purpose-built for automotive segment LCD instrument clusters thanks to its AEC-Q100 automotive screening (VAO suffix), integrated charge pump that runs the LCD glass from a single 3.3V rail, and 64-VFQFN exposed-pad footprint that dissipates segment-driver heat efficiently. Its 28KB flash fits typical cluster state machines including ODOMETER, TRIP, gear-position and diagnostic-indicator maps with comfortable headroom. XLP sleep currents under 1 uA let the cluster survive 30 days of vehicle storage without draining the 12V battery via the always-on supply. PPS lets the designer remap LCD segment lines to avoid crossing analog traces for cleaner EMC performance.

Battery-Powered Smart Thermostat
Battery-powered smart thermostats need an MCU that can drive a multi-digit LCD glass for years on AA cells while running a low-power radio stack. The PIC16LF19196-E/5LXVAO delivers nanoWatt XLP deep-sleep currents and the integrated charge pump removes the external DC-DC required to bias the LCD. Its 32MHz core gives enough headroom for HVAC control loops, FOTA handling, and BLE command processing. The 64-VFQFN package keeps the board footprint small enough to fit behind standard US wall plates, while the exposed pad handles segment-driver thermal load during long LCD-backlight test cycles.

Medical Infusion Pump HMI
Medical infusion pumps require fail-safe displays with audible/visual feedback, and the PIC16LF19196-E/5LXVAO meets this need with its automotive-grade reliability pedigree, integrated LCD charge pump, and CIP peripherals like zero-cross detection that simplify mains-frequency synchronization. The 28KB flash fits the safety state machine and parameter menus; 256 bytes of EEPROM backs up calibration data across power cycles. The 12-bit ADC channels monitor occlusion pressure and bubble detection, while the comparator wakes the MCU from sleep on alarm events. AEC-Q100 screening reduces qualification effort for FDA submissions referencing automotive-grade ECUs as risk benchmark.

IoT Sensor Node with Segment LCD
Remote IoT sensor nodes that display last-known reading on an LCD need ultra-low standby current and integrated display drive. The PIC16LF19196-E/5LXVAO draws under 1 uA in deep sleep with the LCD still alive, courtesy of the integrated charge pump and Core Independent Peripherals. Its 32MHz performance handles LoRaWAN or BLE command stacks, while 28KB flash comfortably fits the radio driver and application logic. The 64-VFQFN exposed pad provides robust thermal performance for outdoor enclosures with wide temperature swings.

Industrial HVAC Controller
Commercial HVAC controllers blend segment-LCD user interfaces, triac phase-angle control, and 24VAC power supply rails. The PIC16LF19196-E/5LXVAO handles up to 32MHz of zero-cross timing, PWM control for variable-speed fans, and the LCD user interface with a single charge pump. Its 64-VFQFN package supports 4-layer FR4 PCBs with the copper area required for high-current segment drivers. The integrated 5-bit DAC and 12-bit ADC close the feedback loop for temperature and humidity sensing, while eXtreme Low-Power technology cuts standby consumption below 1W per zone in large multi-zone buildings.
Được đề xuất
Smart Meter and Utility Display
Smart electricity, water, and gas meters require a segment-LCD readout that survives 10+ years on a primary lithium cell. The PIC16LF19196-E/5LXVAO delivers this longevity through XLP nanoWatt technology and integrated LCD charge pump that runs the glass from a single 3.3V rail without an external boost converter. Its 28KB flash stores consumption logs, tariff tables, and DLMS/COSEM application code with room to spare. The CIP analog chain (12-bit ADC, comparators, zero-cross detect) interfaces directly to current-transformer or pulse-meter front-ends, while the 64-VFQFN exposed pad copes with harsh outdoor thermal swings up to +125C.

Ghi chú thiết kế
The PIC16LF19196-E/5LXVAO 64-VFQFN package requires the exposed thermal pad to be soldered to a copper pour of at least 1 square cm on the top or bottom PCB layer. Estimated steady-state junction temperature with 100 mA segment-driver load at 25C ambient stays below 70C when the pad is properly stitched with thermal vias. Use a 4-layer PCB with a continuous ground plane for best thermal performance; a 2-layer board is acceptable but requires extra copper around the exposed pad.
Keep the analog supply traces (AVDD/AVSS) short and route them away from the LCD segment lines to avoid segment-driver noise coupling into ADC measurements. Place the 100 nF decoupling capacitors as close as possible to each VDD/VSS pair (pins 10/9, 20/19, 62/61). For the LCD charge pump, place the VLCD reservoir capacitor (typically 1 uF X7R) directly on the VLCD pin (pin 63) with a star ground return to pin 61 to minimize ripple.
To achieve XLP nanoWatt sleep current, disable all unused peripherals via the PMD (Peripheral Module Disable) registers before entering sleep mode. Switch the MCU clock source to LFINTOSC or external 32.768 kHz crystal for RTC operations to minimize active current. The integrated LCD charge pump can be turned on while the CPU sleeps, so the display remains visible during deep-sleep - configure LCDCON register accordingly to avoid waking the MCU just to refresh the display.
The PPS (Peripheral Pin Select) feature must be configured early in firmware initialization - failing to unlock PPS (PPSLOCKED bit) leads to silent pin remap failures where the chosen peripheral still toggles the default pin. Always verify the PPS mapping in the IO_MAPPING.CFG file generated by MCC before flashing production firmware. Also, configure unused pins as outputs tied low (not inputs floating) for EMC robustness in AEC-Q100 applications.
