PIC16F19196-I/MR - 8-bit 32MHz 28KB Flash MCU | Microchip
MPN: PIC16F19196-I/MR ✓ فعالPIC16F19196-I/MR نمای کلی
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.

یادداشت‌های طراحی
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.
