PIC16F19196-I/MR 概述
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable peripherals. Within the hierarchy of embedded semiconductors, an 8-bit MCU sits below 16-bit and 32-bit parts in computational throughput, but typically excels at deterministic I/O handling, low power consumption, and lower unit cost. The PIC16 family in particular emphasizes eXtreme Low-Power (XLP) operation and Core Independent Peripherals (CIPs), letting the CPU sleep while peripherals handle timing-critical tasks in hardware.
Key features include 49 high-current source/sink I/O pins, an integrated charge pump for LCD contrast, a 32 MHz internal oscillator, up to 5-bit DAC and 12-bit ADC2, zero-crossing detection, Complementary Waveform Generator (CWG) and PWM with multiple channels. The 64-QFN (9x9) package offers a small footprint and exposes an EP for thermal dissipation and PCB ground integrity.
Architecture is built around the enhanced mid-range PIC16 core with a 14-bit instruction word and hardware multiplier, providing predictable single-cycle execution for CIPs and interrupt-driven firmware. The on-chip charge pump, LCD voltage regulator, and RTCC allow deep-sleep current in the nano-amp range, supported by XLP sleep, Idle and Doze modes. PPS (Peripheral Pin Select) makes pin mapping flexible across 64 pins.
Typical applications include battery-powered LCD thermostats and metering, IoT sensor nodes with local display, medical handheld instruments, industrial HMIs with segment displays, smart wearables and e-paper controllers. The combination of an integrated LCD driver and eXtreme Low-Power makes this part particularly well suited for any battery-powered product with a segment or character display.
When designing with this part, place the exposed pad (EP) to a continuous ground copper pour for thermal relief and ground integrity, and follow Microchip AN2447 LCD layout guidance for low-noise pixel operation. Use PPS to reassign peripheral functions to convenient pins, leaving firmware portable across the 19195/6/7 family.

典型应用
PIC16F19196-I/MR 适用于 6 应用s: Battery-Powered Thermostat with LCD, IoT Sensor Node with Local Display, Medical Handheld Instrument, Industrial HMI / Segment Display Controller, Smart Wearable with E-Paper / Segment LCD, Smart Metering / Utility Display.
Battery-Powered Thermostat with LCD
The PIC16F19196-I/MR is ideal for battery-powered thermostats where its integrated LCD segment driver, charge pump, and XLP nano-amp sleep current extend coin-cell life to 5+ years. The 28 KB Flash holds HVAC control firmware and scheduling logic, while 12-bit ADC2 with computation samples temperature directly without CPU wake-up. Place it as the sole MCU on the PCB with an LCD glass, thermistor, and relay driver; the integrated charge pump removes the need for an external bias inverter, reducing BOM by 4-6 components versus discrete solutions.
推荐
IoT Sensor Node with Local Display
For IoT sensor nodes with a local segment LCD, the PIC16F19196-I/MR delivers 8 MIPS performance while Core Independent Peripherals handle ADC sampling, PWM-driven sensor excitation, and SMT timing in hardware. Its PPS allows peripheral pin reassignment, simplifying PCB routing on compact sensor boards. Sleep current in the nano-amp range supports multi-year battery life, and the integrated LCD driver eliminates the need for a separate display controller, reducing total BOM cost by 15-25% versus two-chip designs.
推荐
Medical Handheld Instrument
Medical handheld instruments such as blood pressure monitors, glucose meters, and pulse oximeters benefit from the PIC16F19196-I/MR's deterministic 8-bit core, integrated LCD driver, and ultra-low sleep current. The 12-bit ADC2 with computation performs oversampling and averaging in hardware without waking the CPU. According to Microchip's medical design guides, the XLP architecture supports IEC 60601-1 compliant battery operation with segment display readability across wide viewing angles, critical for patient-facing diagnostics.
推荐
Industrial HMI / Segment Display Controller
Industrial HMI panels with segment or character LCDs use the PIC16F19196-I/MR to drive the display, scan keypads, and handle Modbus communication over UART. Its 49 high-current source/sink I/O pins directly drive LED backlights and key matrix without external drivers. PPS maps UART, SPI, and I2C peripherals to any convenient pin, simplifying PCB layout. The 32 MHz core runs Modbus RTU at full baud rates while CIPs handle background keypad debounce in hardware.
推荐
Smart Wearable with E-Paper / Segment LCD
Smart wearables requiring months of battery life and a low-refresh display pair the PIC16F19196-I/MR's XLP architecture with an e-paper or segment LCD. The integrated LCD charge pump maintains display contrast across the battery's discharge curve, while the RTCC maintains accurate timekeeping at <1 uA. According to Microchip XLP datasheets, sleep currents below 50 nA enable wearables that operate for years on a CR2032 cell, with the 8 MIPS core handling BLE command processing on wake.
推荐
Smart Metering / Utility Display
Smart electricity, gas, and water meters use the PIC16F19196-I/MR as the local display and metering controller. The integrated LCD driver supports large segment count for kWh, voltage, and current displays, while 12-bit ADC2 with computation samples current shunt signals at high accuracy. The XLP architecture supports 10+ year battery life mandated by utility metering standards, and the RTCC tracks time-of-use billing schedules without external components, reducing total BOM and improving MTBF.

设计说明
The 64-QFN (9x9) package includes a central exposed pad (EP, pin 64) that MUST be soldered to a continuous ground copper pour of at least 1 square inch for thermal dissipation and electrical ground integrity. Estimated: at 32 MHz with all peripherals active, the device dissipates approximately 30-40 mW, well within QFN thermal limits, but the EP also reduces ground bounce on the segment LCD lines. For battery-powered designs with sustained high I/O sourcing, expand the copper pour to 2-3 square inches for additional margin.
Follow Microchip AN2447 LCD layout guidance: keep LCD segment and common traces short, route them away from high-frequency digital lines, and use a ground guard ring around the LCD glass connector. Place 0.1 uF decoupling capacitors as close as possible to each VDD/VSS pair. The PPS feature allows relocating peripherals to convenient pins - reassign UART, SPI, and I2C to free pins if PCB layout forces, and update firmware to match the new PPS mapping at startup.
Do not skip the exposed-pad (EP) solder connection even if the design is low-power - the EP is the primary ground return for the LCD driver and skipping it causes contrast loss and pixel ghosting. Always configure unused I/O pins as outputs (not inputs) to minimize sleep current leakage. When migrating between PIC16F19195/6/7 family variants, verify Flash size and EEPROM size in firmware headers; register layouts are otherwise identical. For RTCC accuracy, use the 32.768 kHz external crystal rather than the internal LF-OSC for timekeeping within +/- 20 ppm.
