PIC16F19175-E/PT - 8-bit 32MHz 14KB Flash LCD MCU | Microchip
MPN: PIC16F19175-E/PT ✓ Hoạt độngPIC16F19175-E/PT Tóm tắt
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash/ROM), data memory (RAM), and integrated peripherals such as ADCs, timers, communication interfaces, and I/O pins. PIC® microcontrollers use a RISC architecture with a fixed instruction set optimized for deterministic real-time control, placing them in the broader hierarchy of microcontrollers -> embedded controllers -> semiconductor ICs. The XLP™ (eXtreme Low-Power) family is specifically tuned for battery-powered applications where sleep current is critical.
Key features include the integrated LCD charge pump that generates VLCD from the main supply without external boost components, 12-bit ADC2 with computation, dual low-power comparators with programmable reference, and Core Independent Peripherals (CIPs) that operate without CPU intervention. The device supports 1.8V-5.5V operation across the PIC16F19175 (F) variant with on-chip voltage regulator and brown-out reset. Intelligent Analog peripherals include the 12-bit ADC, 5/8-bit DAC, and zero-cross detect (ZCD) for TRIAC control.
The PIC16F19175 uses Microchip's enhanced mid-range 8-bit core running at 32 MHz with 8 MIPS throughput, supported by 14 KB self-programmable Flash, 1024 bytes SRAM, and 256 bytes high-endurance EEPROM (100k erase/write cycles). Hardware CIPs include the SMT (Signal Measurement Timer), CWG (Complementary Waveform Generator), and Configurable Logic Cell, enabling complex timing and signal generation tasks without software overhead.
Typical applications include battery-powered glucose meters and blood pressure monitors with LCD readout, smart thermostats and HVAC controllers, industrial sensor transmitters with LCD display, electronic shelf labels (ESL), utility metering endpoints with LCD, and remote control units with status display. The integrated LCD driver supporting up to 357 segments eliminates external display drivers.
When designing with this device, pay attention to VLCD charge pump capacitor selection and consider the 5x8 font ROM for ASCII character generation. The PPS (Peripheral Pin Select) provides flexible I/O mapping, but designers must still respect analog/digital pin separation to avoid injection current issues.

Ghi chú thiết kế
The PIC16F19175-E/PT supports multiple low-power modes including SLEEP, IDLE, and DOZE. Sleep current with LCD charge pump active is typically below 1 uA, making the device ideal for battery-powered applications. Use the LCD charge pump in sleep mode to maintain display refresh without CPU intervention. Configure unused peripherals to their lowest power state via the PMDx registers and disable the ADC and comparators when not in use to achieve minimum quiescent current.
Place decoupling capacitors (100 nF ceramic plus 1 uF bulk) within 5 mm of each VDD/VSS pair on the 44-pin TQFP package. Connect all VSS pins to a single ground plane, and place the VLCD charge pump capacitors (typically 1 nF to 10 nF ceramic) close to the VLCD pin to minimize ripple. The crystal oscillator traces must be short and surrounded by ground pour; avoid routing digital signals under the crystal or charge pump capacitors to prevent noise injection into the LCD bias.
Do not exceed the absolute maximum ratings of 6.5V on VDD or inject current into analog pins when the device is unpowered. Always configure the PPS (Peripheral Pin Select) carefully - some peripheral functions are only available on specific pins. Verify the MCLR pin configuration: by default MCLR is enabled and requires a pull-up resistor; if unused, configure as a digital input to avoid unwanted resets. The LCD segment pins have specific drive strength limitations when used at high segment counts.
When routing the 32 MHz HFINTOSC clock output (CLKOUT), keep the trace under 25 mm and avoid parallel runs with analog signals. The SMT (Signal Measurement Timer) input pins require a clean signal - add a 1k series resistor at the source if driving from an external noisy source. For UART communication with wireless modules, add 100 ohm series resistors at TX/RX to dampen reflections on long traces. The 12-bit ADC2 achieves best results with an input bandwidth filter below 10 kHz.
