PIC16LF19196-I/PT - 32MHz 8-bit XLP MCU, 28KB Flash, 64-TQFP | Microchip
MPN: PIC16LF19196-I/PT ✓ Hoạt độngPIC16LF19196-I/PT Tóm tắt
An 8-bit microcontroller (MCU) is a microprocessor with an 8-bit data bus, typically combining a CPU, RAM, Flash, and peripherals on a single die. The PIC16 family sits within Microchip's broader PIC® product hierarchy (PIC10/12/16/18/24/dsPIC33), positioned as the mainstream mid-range MCU family below PIC18 in performance but above baseline PIC10/12 in peripheral integration. 8-bit MCUs remain the workhorses of cost- and power-sensitive embedded designs where 32-bit ARM Cortex-M devices are overkill.
Key features of the PIC16LF19196 include eXtreme Low-Power (XLP) technology with deep-sleep currents in the nanoamp range, an integrated charge pump for LCD bias generation, high-current I/O capable of directly driving backlight LEDs, and battery backup of the on-chip Real-Time Clock/Calendar (RTCC). The 64-pin TQFP package exposes 54 I/O pins, providing abundant connectivity for keypad, display, and sensor interfaces in human-machine interface designs.
On the analog side, the device integrates a 12-bit ADC with computation (ADC2), a 5-bit/10-bit DAC, a low-power comparator, zero-cross detect (ZCD), and a peripheral touch controller. CIPs such as CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), PWM, CCP, and PPS (Peripheral Pin Select) offload timing-critical tasks from the CPU, reducing firmware complexity and power consumption.
Typical applications include battery-powered blood-glucose meters, thermostatic radiator valves, electronic shelf labels, smart thermostats, industrial sensor transmitters, and wearable medical devices where long battery life and on-board LCD readout are both required. The integrated charge pump eliminates an external LCD bias supply, reducing BOM cost and PCB area.
When designing with this MCU, choose the LF (low-voltage, low-power) variant if your system runs from 1.8V–3.6V; the non-LF PIC16F19196 is required for 5V operation. PPS provides remappable peripherals but requires care to avoid conflicting assignments; consult the device datasheet's I/O map for valid pin selections.

Ứng dụng tiêu biểu
PIC16LF19196-I/PT phù hợp cho 6 Áp dụngs: Battery-Powered Blood-Glucose Meter, Smart Thermostat with LCD, Electronic Shelf Label (ESL) Wireless Display, Industrial Sensor Transmitter with HMI, Portable Medical Wearable (Insulin Pump / CGM), Wireless Environmental Monitor with LCD.
Battery-Powered Blood-Glucose Meter
The PIC16LF19196-I/PT's eXtreme Low-Power (XLP) technology with deep-sleep currents below 100 nA makes it ideal for blood-glucose meters that must run for years on a single coin cell. The integrated LCD charge pump drives a 4-mux segment display without external boost components, saving PCB area in the slim handheld form factor. The 12-bit ADC2 with computation (averaging, oversampling) directly digitizes the electrochemical test strip's current without a separate analog front-end IC. RTCC with battery backup maintains accurate timestamps for test history even when the main battery is replaced, which is essential for medical-record compliance.

Smart Thermostat with LCD
The PIC16LF19196-I/PT integrates LCD segment drive, RTCC, and 12-bit ADC2 in a single 64-pin TQFP, eliminating the need for a separate LCD driver, real-time clock IC, and external ADC in smart thermostat designs. Its integrated charge pump supports high-segment-count displays (up to 116 segments at 1/4 duty) used for temperature setpoint, schedule icons, and humidity readouts. The 32 MHz CPU at 8 MIPS handles PID loop execution, capacitive touch sensing via the mTouch peripheral, and Zigbee/BLE command processing for Wi-Fi models. XLP deep-sleep mode drops consumption below 1 µA between sensor samples, enabling 1-year battery life on the C-wire backup.

Electronic Shelf Label (ESL) Wireless Display
Electronic shelf labels require a low-power MCU that can drive an LCD for years on a coin cell while periodically waking to receive RF updates. The PIC16LF19196-I/PT's integrated LCD charge pump drives 4-mux segment LCDs directly without external bias components, reducing the BOM by 2-3 capacitors and an inductor. Its nanoamp deep-sleep current extends battery life to 5-7 years, while the 32 MHz core executes sub-GHz radio packet handling and display refresh in milliseconds. The 64-pin TQFP package supports up to 116 LCD segments for price, unit, and promotional-icon display on retail-shelf form factors.

Industrial Sensor Transmitter with HMI
Industrial 4-20 mA loop-powered sensor transmitters benefit from the PIC16LF19196-I/PT's 1.8V minimum operating voltage, allowing operation directly from a 4 mA loop current with an efficient shunt regulator. The 12-bit ADC2 with hardware averaging provides stable readings from bridge-type pressure sensors, RTDs, or load cells without external signal conditioning. CWG, PWM, and CCP peripherals drive HART modems or 4-20 mA DAC loops, while the integrated LCD shows process variables locally without a separate display driver. PPS enables flexible I/O mapping, simplifying PCB routing in compact field-mount enclosures.

Portable Medical Wearable (Insulin Pump / CGM)
Wearable medical devices such as continuous glucose monitors (CGM) and insulin pumps demand deterministic low-power operation, integrated display, and robust ADC performance - all delivered by the PIC16LF19196-I/PT in a 64-TQFP. The 12-bit ADC2 with hardware oversampling achieves 16-bit effective resolution for the sub-micromolar glucose-oxidase sensor signals, eliminating external ADCs. XLP sleep modes below 100 nA extend 7-day patch wear time, while the RTCC provides accurate dosing timestamps for therapy logs. The integrated LCD drives the on-patch status display, removing an external display-driver IC.

Wireless Environmental Monitor with LCD
Wireless indoor air-quality monitors combine VOC, CO2, temperature, and humidity sensors with an LCD readout. The PIC16LF19196-I/PT handles I2C/SPI sensor polling at 32 MHz, processes readings through its 12-bit ADC for analog channels, and updates a 4-mux segment LCD via the integrated charge pump without external bias components. CWG drives a buzzer for CO2 alarm thresholds, while RTCC timestamps logged events. The XLP deep-sleep current (sub-100 nA) combined with periodic wake cycles enables 1-2 year battery life on two AA cells, making it ideal for wall-mounted air-quality stations.

Ghi chú thiết kế
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pins 15 and 42 (the two VDD/VSS pairs on the 64-TQFP). For battery-powered designs, use Sleep mode with RTCC retention (typical current < 100 nA per the datasheet) and wake via RTCC alarm or external interrupt on RB0. Avoid leaving floating analog inputs during sleep as they leak current; configure unused I/O as outputs driven low. Estimated: if wake-up is once per second for a 1 ms ADC sample at 32 MHz, average current stays below 5 µA.
The 64-TQFP (10x10 mm, 0.5 mm pitch) requires reflow soldering with a fine-paste stencil (4-5 mil thickness). Place the ICSP programming header (ICSPCLK on RB6, ICSPDAT on RB7) on the PCB edge for in-circuit programming - do not route signals through these pins that would block debug access. Keep analog input traces short and guarded by ground pours to preserve 12-bit ADC2 accuracy; the datasheet recommends 4-layer PCBs for best ADC performance in noisy environments.
PPS (Peripheral Pin Select) mappings can conflict if you assign two peripherals to the same pin - always consult the datasheet's I/O map table to verify uniqueness before locking the pinout. The integrated LCD charge pump requires external capacitors on the VLCD pins; omitting them will disable the LCD driver entirely. When migrating from PIC16LF19196 to PIC16F19196 (5V variant), verify all analog inputs stay within the new absolute-maximum ratings, especially in systems where external sensors can present transients.
For 32 MHz operation, route the external oscillator traces on the top layer only, with ground guarding on both sides and length < 10 mm. If using the internal 32 MHz HFINTOSC instead, expect ±2% frequency accuracy over temperature - inadequate for UART communications at > 57600 baud without software calibration against the RTCC 32.768 kHz reference. Estimated: the datasheet specifies 16 MHz HFINTOSC typical accuracy of ±1% over 0-85C; calibrate at production for reliable serial comms.
