PIC16F19195T-I/MR - 8-bit XLP MCU, 14KB Flash, 64-QFN | Microchip
MPN: PIC16F19195T-I/MR ✓ Hoạt độngPIC16F19195T-I/MR Tóm tắt
An 8-bit PIC microcontroller (MCU) is a Harvard-architecture embedded controller that executes one byte-wide instruction per cycle from internal Flash, providing deterministic real-time response in cost-sensitive applications. Within the broader taxonomy it sits under microcontroller -> embedded controller -> semiconductor device, and is the workhorse of consumer appliances, industrial sensors, and battery-powered LCD products where low active current and deep-sleep nanoWatt XLP modes are essential.
Key features include operation from 1.8V to 5.5V, integrated charge pump for LCD bias generation, high-current I/O for directly driving LEDs and segment lines, and communication peripherals (I2C, SPI, UART/USART, LIN). The XLP technology delivers active currents in the microamp range and deep sleep currents below 100 nA typical, allowing multi-year coin-cell operation in metering and wearable products.
Architecturally, the PIC16F19195 uses a RISC-style 14-bit instruction word with a 16-level hardware stack and 49 instruction set optimized for compiled C code via Microchip's MPLAB XC8 toolchain. The CIP block (CLC, NCO, PWM, COG) offloads timing-critical tasks from the CPU, improving system-level power efficiency.
Typical applications include battery-powered LCD thermostats, household metering displays, IoT sensor nodes with segmented displays, medical glucose/peak-flow meters, and industrial HMI panels. The integrated charge pump eliminates external LCD bias components, reducing BOM cost by up to 30% versus discrete LCD-driver designs.
When designing with this device, ensure the exposed pad is soldered to a continuous ground copper pour of at least 25 mm squared to meet the 9x9 mm QFN thermal envelope. Use MPLAB Code Configurator (MCC) plugins to generate peripheral initialization code, which significantly reduces firmware development time for the CIP peripherals.

Ghi chú thiết kế
The 64-QFN (9x9 mm) package has an exposed thermal pad (EP) that MUST be soldered to a continuous ground copper pour of at least 25 mm squared on the top and bottom layers. Estimated: with EP properly soldered, theta_JA is approximately 25 C/W; without EP soldering it rises to over 60 C/W and the device may exceed its +85C industrial limit at full 32 MHz / 5.5V operation. Use at least four 0.4 mm thermal vias in the EP land pattern to conduct heat into inner ground planes.
Place a 100 nF decoupling capacitor within 3 mm of each VDD pin (multiple VDD pins on 64-QFN) and a single 4.7 uF bulk capacitor near the package. Add a 10 uF bulk capacitor on the LCD charge-pump output (VLCD pin) if using high-segment-count displays. Per Microchip datasheet DS40001953, all VSS pins must be connected to the ground plane, and trace lengths from VDD/VSS to capacitors must be minimized to reduce switching noise coupling into the ADC reference.
Do not leave MCLR floating - tie to VDD through a 10 kohm pull-up or drive from a microcontroller supervisor for production designs, as floating MCLR can cause spurious resets. When migrating from PIC16F19155/PIC16F19156 to PIC16F19195, verify the LCD pin assignments - PIC16F19195 has more LCD segment pins than earlier PIC16F1xxx families. Use the MPLAB Code Configurator (MCC) to regenerate peripheral setup code and avoid register-name mismatches. Always configure unused I/O pins as outputs driving low to minimize sleep current.
Keep the 32 MHz oscillator traces (OSC1/OSC2) or the external crystal within 5 mm of the MCU and surrounded by a ground guard ring. For ADC accuracy, route analog signals (ANx) away from the LCD segment lines and charge-pump switching traces; the LCD charge pump generates up to 3Vpp ripple that can couple into sensitive analog channels if routing is not separated by at least 5 mm or a ground trace.
