PIC16F19196T-I/MR 概述
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (FLASH program memory, SRAM data memory, EEPROM), peripherals (ADC, timers, communication interfaces), and I/O pins on one die. The PIC16F191xx family belongs to the broader 8-bit MCU category (8-bit microcontroller → PIC microcontroller → Microchip 8-bit MCU portfolio → embedded microcontroller) and is specifically engineered for eXtreme Low Power (XLP) designs with integrated LCD drive.
Key features include an integrated charge pump for contrast generation on LCD glass without external boost circuitry, Core Independent Peripherals (CIPs) such as CRC/SCAN, Hardware Limit Timer (HLT) and Windowed Watchdog Timer (WWDT) for functional safety, high-current I/O pins capable of directly driving LED segments, and the XLP sleep modes that consume nanoamps to extend battery life in always-on systems. The 64-QFN 9x9 mm footprint provides 64 pins in a compact surface-mount outline with an exposed thermal pad.
The device uses an enhanced mid-range 8-bit RISC core with a 14-bit instruction word, hardware multiplier, and Interrupt-on-Change (IOC) support. It includes multiple communication peripherals (UART, SPI, I2C), a 12-bit ADC with Computation (ADC2), and intelligent analog features like on-chip comparators with voltage reference.
Typical applications include battery-powered glucose meters, thermostatic radiator valves, portable medical infusion pumps, IoT sensor nodes with LCD readouts, electronic shelf labels, utility meters, and consumer appliances with segmented displays. The LCD charge pump and XLP sleep modes make it particularly well-suited for applications powered by a CR2032 coin cell.
When designing with this part, ensure the exposed thermal pad on the 64-QFN package is soldered to the PCB ground plane for thermal dissipation and electrical grounding. The LCD charge pump requires sufficient external reservoir capacitors for stable segment drive voltages.

典型应用
PIC16F19196T-I/MR 适用于 6 应用s: Battery-Powered Smart Thermostat, Utility Electricity Meter with LCD, Portable Medical Infusion Pump, Electronic Shelf Label (ESL) Wireless Node, Industrial Process Indicator with LCD, IoT Sensor Hub with Local LCD Readout.
Battery-Powered Smart Thermostat
The PIC16F19196T-I/MR is ideal for battery-powered smart thermostats that drive a segmented LCD to display setpoint, current temperature, and system status. The integrated LCD charge pump generates bias voltages without an external boost converter, saving board area and quiescent current. XLP sleep currents in the nanoamp range allow a CR2032 coin cell to power the device for years. The 28KB FLASH accommodates adaptive control firmware plus on-screen menu structures, while the 12-bit ADC with Computation (ADC2) oversamples the thermistor sensor to filter out supply-rail ripple noise in the conditioning circuit.
推荐
Utility Electricity Meter with LCD
The PIC16F19196T-I/MR drives the segmented LCD on a residential electricity or water meter, displaying cumulative consumption, current draw, and tariff block. Its integrated LCD charge pump eliminates the high-voltage inverter typically needed for LCD bias, while the 32MHz CPU processes pulse-count inputs from the metrology front-end. The 256-byte EEPROM stores rolling consumption logs that survive power loss, and the WWDT (Windowed Watchdog Timer) provides functional safety against runaway firmware in a regulated metering product. Wide 1.8-3.6V operation supports direct connection to the meter's lithium backup cell.
推荐
Portable Medical Infusion Pump
The PIC16F19196T-I/MR runs the user interface and alarm logic of a portable medical infusion pump. The 64-QFN 9x9 mm package fits a compact handheld enclosure, and the exposed pad handles thermal dissipation when the MCU is active. Its CRC/SCAN Core Independent Peripheral provides continuous memory integrity checking for IEC 62304 risk management, while HLT (Hardware Limit Timer) enforces maximum motor-on duration for patient safety. The 32MHz CPU executes PID control loops for flow regulation, and XLP sleep modes extend battery runtime between charges in the clinical mobile-care workflow.
推荐
Electronic Shelf Label (ESL) Wireless Node
The PIC16F19196T-I/MR drives a segmented bistable or segmented LCD in a retail electronic shelf label that receives price updates over an RF link. XLP sleep modes keep the MCU asleep until an RF interrupt wakes it, then the integrated LCD charge pump drives the display refresh without an always-on boost converter. The 28KB FLASH holds communication protocol stack and display-mapping tables. The 12-bit ADC monitors battery voltage for low-battery alerts, and the I2C peripheral connects to an external temperature sensor for shelf-environment monitoring.
推荐
Industrial Process Indicator with LCD
The PIC16F19196T-I/MR displays measured process variables (pressure, temperature, flow) on a 4-7 segment industrial indicator mounted in a factory-floor enclosure. The -40C to +85C industrial temperature range supports operation in unheated cabinets, while the wide 1.8-3.6V supply tolerates 24V loop-powered industrial rails after regulation. CRC/SCAN provides on-demand memory integrity checks, and the 12-bit ADC with computation offers oversampling for noise-immune measurement from 4-20 mA loops. The QFN exposed pad enables high-power dissipation for the hot-enclosure environment.
推荐
IoT Sensor Hub with Local LCD Readout
The PIC16F19196T-I/MR acts as a low-power sensor hub that aggregates multiple sensor inputs and shows readings on a local segmented LCD. The CPU runs at 32MHz to service multiple SPI/I2C sensors, and CIP peripherals offload CRC checking and watchdog duties from the core. The integrated LCD charge pump removes the need for a separate display bias IC, reducing BOM count and standby current. Designers porting firmware to this device from older PIC16 designs find the enhanced mid-range core compatible at the instruction-set level.

设计说明
The 64-QFN exposed thermal pad must be soldered to the PCB ground plane for both electrical grounding and thermal dissipation. Use an array of thermal vias (0.3 mm drill, 0.5 mm pitch) under the pad to conduct heat into the inner ground planes. Without proper pad soldering, the junction temperature can rise substantially under continuous CPU load, reducing long-term reliability.
For the LCD charge pump to provide stable bias voltages, place the reservoir and flying capacitors as close as possible to the LCD-C pins. Microchip recommends low-ESR ceramic capacitors (typically 1uF X7R) for both CP1/CP2 charge-pump reservoirs. Insufficient bulk capacitance will cause visible LCD flicker under temperature extremes, especially below 0C.
Place the 32.768 kHz external crystal (if used for the RTCC) within 5 mm of the SOSCO/SOSCI pins, with guard traces connected to analog ground to block digital noise coupling into the low-amplitude oscillator. For battery-powered designs with no external crystal, configure the LFINTOSC internal low-frequency oscillator at 31 kHz to minimize sleep current to a few hundred nanoamps.
When migrating firmware from the PIC16F19195 to the PIC16F19196, verify that all RAM-bound variables fit in the larger 2KB RAM space - the increased RAM can mask bugs related to memory-bank aliasing that did not appear on the 19195. Also confirm interrupt vector mappings, because the 19196 includes additional CIP interrupt sources (HLT, WWDT) that the smaller variant may not have.
