PIC16LF19196-I/PT - 32MHz 8-bit XLP MCU, 28KB Flash, 64-TQFP | Microchip

The Microchip Technology PIC16LF19196-I/PT is an 8-bit PIC16 microcontroller from the PIC® XLP™ 16F family, featuring 32 MHz CPU speed, 28 KB (16K x 14) of Flash program memory, and housed in a 64-pin TQFP (10x10 mm) package. It is purpose-built for low-power, battery-driven applications requiring integrated LCD drive, intelligent analog, and Core Independent Peripherals (CIPs). 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.

PIC16LF19196T-E/MRVAO

PIC16LF19196T-E/MRVAO - 28KB Flash 8-bit MCU, 64-QFN, Automotive | Microchip

The Microchip Technology PIC16LF19196T-E/MRVAO is an 8-bit RISC PIC microcontroller from the PIC16F19196 family featuring eXtreme Low-Power (XLP) technology and an integrated LCD driver, housed in a 64-pin QFN (9x9 mm) package with automotive-grade temperature rating. It runs up to 32 MHz from an internal oscillator, delivers 28 KB (16K x 14) of Flash program memory, and is qualified to AEC-Q100 standards for automotive dashboard, body-control and HMI applications. An 8-bit microcontroller (MCU) is a small, self-contained computer-on-a-chip built around an 8-bit data path. It integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), peripherals such as timers, ADC, communication ports and interrupt logic into a single package. MCUs sit below microprocessors in the system hierarchy: MCU -> microcontroller -> embedded controller -> semiconductor, and they power everything from toys and appliances to automotive ECUs and industrial sensors. The PIC16F19196 family in particular targets ultra-low-power LCD applications by adding an on-chip LCD charge pump, high-current I/O and Core Independent Peripherals (CIPs) that offload tasks from the CPU. Key features of the PIC16LF19196T-E/MRVAO include 28 KB Flash / 2 KB RAM (typical for this family), an integrated 10-bit ADC, multiple Enhanced Universal Synchronous/Asynchronous Receiver Transmitters (EUSART), I2C/SPI peripherals, a hardware Real-Time Clock and Calendar (RTCC), and a charge-pump-driven LCD driver capable of up to 384 segments. The 8-bit PIC core delivers deterministic 1-instruction-per-clock execution at 32 MHz, while XLP technology keeps active current in the microamp range and deep-sleep current below 100 nA. The automotive-grade temperature range of -40C to +125C and AEC-Q100 qualification are critical for under-hood and dashboard deployments. The architecture combines a Harvard RISC CPU with separate program and data buses, allowing simultaneous fetch and access. Core Independent Peripherals (CIPs) such as Configurable Logic Cells (CLCs), Signal Measurement Timers (SMTs) and the Numerically Controlled Oscillator (NCO) let the device react to events without waking the core. This reduces active CPU duty cycle, extending battery life in wireless sensors, smart thermostats and wearable medical devices. Typical applications include automotive instrument clusters with LCD or segment displays, body-control modules, e-bike and e-scooter HMI panels, battery-management front-ends with on-screen SOC indication, white-goods user interfaces, and portable medical monitoring devices that must survive extended idle periods on a coin cell. The wide operating voltage range (1.8 V to 3.6 V typical for the LF variant) lets the part run directly from a single Li-ion or two AA cells. Designers should pair the MCU with the recommended 0.1 uF + 10 uF decoupling network, route the analog AVSS/AVDD pair as a star from a quiet regulator, and reserve one GPIO as an external interrupt for instant wake from sleep. Compared with older PIC16F1 designs, the F19196 family's CIPs and RTCC significantly reduce firmware complexity for user-interface tasks, but code density may increase because each instruction is 14 bits wide.

The PIC16LF19196 architecture uses a RISC-style 14-bit instruction word with a 32-level hardware stack and an instruction-cycle-time of four clock periods, yielding 8 MIPS per MHz. The integrated charge pump and LCD driver allow glass bias generation from a single low-voltage rail without external boost components, simplifying BOM count for battery powered meter and appliance displays. Typical applications include battery powered LCD meters, thermostat and HVAC control panels, portable medical monitors, IoT sensor nodes with segment displays, white goods user interfaces, and remote controls with capacitive touch buttons. The 1.8V minimum Vdd enables single-cell Li-coin or 2x AA-alkaline designs where energy budget is critical. When designing with this part, choose the LF (low-voltage) variant only if the supply rail will not exceed 3.6V. For 5V-tolerant systems use the PIC16F19196 (5V) variant instead. The 64-QFN package has an exposed pad that must be soldered to the ground plane for thermal and electrical performance per the Microchip datasheet.

PIC16LF19197-E/MR

PIC16LF19197-E/MR - 56KB Flash XLP LCD MCU | Microchip

The Microchip Technology PIC16LF19197-E/MR is an 8-bit PIC16 XLP microcontroller with 56KB Flash, 4KB RAM, and 256 bytes EEPROM, operating up to 32 MHz in a 64-pin QFN (9x9) package. It features a low-voltage 'LF' core optimized for eXtreme Low-Power (XLP) operation, an integrated LCD driver with charge pump, Core Independent Peripherals (CIPs), and intelligent analog peripherals. The -E temperature grade denotes an extended industrial range of -40C to +125C. A PIC (Peripheral Interface Controller) microcontroller is a compact, programmable computer-on-a-chip built on Harvard architecture. Within Microchip's portfolio, the PIC16 family sits between the PIC10/12/14 baseline line and the PIC18 performance line, targeting low-power embedded applications. The 'LF' prefix indicates a 1.8V-3.6V wide VDD range; 'XLP' denotes Microchip's eXtreme Low-Power technology for battery-driven designs, with sleep currents in the nanoamp range. This particular device family belongs to the hypernym chain: microcontroller -> 8-bit MCU -> PIC16 -> XLP LCD line -> integrated LCD driver MCU. The PIC16LF19197 integrates a 12-bit ADC with Computation (ADC2), a 5-bit DAC, a low-power comparator, zero-cross detect (ZCD), PWM, CCP, CWG, SMT (Signal Measurement Timer), RTCC with Hardware RTCC, Windowed Watchdog Timer (WWDT), Peripheral Module Disable (PMD), and Peripheral Pin Select (PPS) for flexible I/O mapping. It provides up to 56 KB of self-programmable Flash, 4 KB of SRAM, and 256 bytes of EEPROM, enabling firmware field-updates and parameter storage. In the PIC16F19197 family, the 'LF' low-voltage core pairs with a battery-friendly charge pump that keeps the LCD contrast supply stable even when VDD drops toward the brown-out threshold. PPS removes fixed peripheral-to-pin mappings, so engineers can route UART, PWM, and timers to any available I/O, simplifying PCB layout. The CWG (Complementary Waveform Generator) and SMT timers reduce CPU overhead for motor control and signal measurement tasks, while PMD allows unused peripherals to be fully powered down, cutting dynamic current. Typical applications include battery-powered LCD thermostats, utility metering displays, medical glucose and infusion monitors, IoT sensor nodes with character LCDs, and industrial HMI panels. The XLP active current below 50 uA/MHz and the LCD charge pump keep total system current low enough that two AA alkaline cells can power the device for years. When designing with this MCU, ensure VDD decoupling uses a 100 nF ceramic capacitor placed within 5 mm of the VDD pin, route the charge-pump capacitor (LCD_PUMP) traces short and symmetric to minimize ripple on the LCD bias rails, and use PPS to keep high-speed signals away from analog ADC inputs.

The architecture combines the enhanced mid-range core with self-read/write flash, configurable logic cells (CLC) and a peripheral pin select (PPS) matrix that maps digital peripherals to a wide choice of I/O pins. The nanoWatt XLP sleep current of typically < 50 nA makes the part suited to applications that spend most of their life in standby. Typical applications include low-power consumer LCD products, battery-powered instrumentation, capacitive-touch human interfaces, sensor nodes with LCD readout, and industrial control panels. Its combination of LCD driver, mTouch and low quiescent current removes several external components and a dedicated touch controller. When designing with the device, plan current budget around the nanoWatt XLP sleep modes and verify that the chosen regulator can sustain the LCD charge-pump transient load.

An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), non-volatile data memory (EEPROM), and a set of on-chip peripherals (timers, ADC, comparators, communication ports) into one package. Within the broader IC taxonomy, an MCU belongs to the microcontrollers -> microcomputer ICs -> integrated circuits -> semiconductor devices hierarchy. The PIC16 family uses Microchip's enhanced mid-range RISC architecture executing most instructions in a single 200 ns cycle, making it well-suited for cost-sensitive embedded control where deterministic timing and low power are priorities. Key features of the PIC16LF1933 include an integrated LCD driver supporting up to 96 segments, a 10-bit ADC with up to 17 channels, two comparators, multiple PWM modules, two USART, MSSP (SPI/I2C) peripherals, and the nanoWatt XLP sleep current of typically under 50 nA. The 28-pin SPDIP package provides through-hole PCB mounting for prototyping, breadboards, and legacy designs where socketed or hand-solderable parts are preferred over surface-mount alternatives. The LF1933 variant operates from 1.8 V to 5.5 V, making it the lower-voltage counterpart of the PIC16F1933 (2.3 V to 5.5 V). Its nanoWatt XLP technology delivers typical sleep currents in the tens of nanoamps, supporting battery-powered applications such as remote sensors, metering, and wearable devices that require years of operation from a single coin cell. Typical applications include low-power battery sensor nodes, LCD-displayed metering equipment, industrial control panels, home appliances with segment displays, and remote-control key fobs. The on-chip LCD driver eliminates external display controller ICs, reducing BOM cost and PCB area. When designing with this part, ensure that the LF (low-voltage, 1.8 V minimum) variant is used when the supply rail may drop below 2.3 V, such as in 2x AA battery packs near end-of-life. The 'E' suffix indicates the extended -40 C to +125 C operating temperature grade.

Typical applications include battery-powered IoT sensor nodes, low-power wireless endpoints, consumer appliance control panels (with LCD), remote controls, energy-harvesting devices, and small home-automation products where the integrated LCD driver eliminates the need for an external display controller. The 'I' temperature grade and MV package suit industrial-environment designs requiring a compact, thermally efficient 5x5 mm UQFN footprint. When designing with this device, plan for an external decoupling network (typically 100 nF + 10 µF), reserve ICP/ICD programming pins (ICSPCLK/ICSPDAT), and select the appropriate oscillator mode (HFINTOSC is factory-calibrated to ±1%). The internal voltage reference and temperature-indicator module further reduce external BOM cost. This page synthesizes distributor pricing, drop-in alternatives in the same UQFN-40 footprint, and practical design notes not found in the manufacturer datasheet alone.

PIC16LF1934-I/PT - 8-bit XLP MCU, 7KB Flash, 44-TQFP | Microchip
PIC16LF1934-I/PT

PIC16LF1934-I/PT - 8-bit XLP MCU, 7KB Flash, 44-TQFP | Microchip

The Microchip Technology PIC16LF1934-I/PT is an 8-bit PIC16F family microcontroller (MCU) featuring 7KB (4K x 14) of Flash program memory, 256 bytes of SRAM, and 256 bytes of EEPROM, housed in a 44-pin TQFP package measuring 10x10 mm. It operates from 1.8V to 3.6V supply and runs up to 32 MHz internal oscillator (20 MHz factory default), targeting low-power XLP (eXtreme Low Power) applications where extended battery life is critical. A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (typically Flash), working RAM, peripherals (timers, ADC, communication interfaces, I/O), and often EEPROM for data persistence. The PIC16F family sits in Microchip's 8-bit mid-range tier using a 14-bit instruction word, bridging simple PIC10/PIC12 designs and the higher-pin-count PIC18/dsPIC families. The 'LF' voltage range (1.8-3.6V) extends XLP battery operation down to two AA cells. Key features include an integrated LCD driver controller (up to 96 segments), a 10-bit ADC with up to 14 channels, two analog comparators, multiple timers (Timer0/1/2/4/6), EUSART, MSSP (I2C/SPI), mTouch capacitive touch sensing, nanoWatt XLP sleep currents as low as 30 nA typical, and 36 digital I/O pins. The 44-TQFP package exposes nearly all peripherals and supports in-circuit serial programming (ICSP) plus debugging via ICD. Architecturally, the PIC16LF1934 uses a RISC-style Harvard architecture with a 14-bit instruction set, 8-level hardware stack, and a unified data/EEPROM area. The XLP design extends sleep current down to roughly 30 nA (typical) with watchdog and brown-out reset active, an order of magnitude better than legacy PIC16 designs, enabling years of operation from a small battery when the MCU spends most of its time in sleep. Typical applications include battery-powered LCD-based instruments, handheld thermometers, glucose meters, electronic shelf labels, remote sensor nodes with LCD readouts, capacitive-touch human-machine interfaces, low-power IoT sensor endpoints, and consumer white goods with segmented displays. When designing with this part, ensure the ICSP/ICD pinout is reserved on the PCB for production programming and field firmware updates, and place a 100 nF decoupling capacitor within a few millimetres of VDD. The LCD bias capacitors (if charge-pump mode is used) should sit close to the corresponding pins to keep segment noise out of the analog rails.

PIC16LF1934T-I/MV

PIC16LF1934T-I/MV - 8-bit MCU, 7KB Flash, 32MHz, UQFN-40

The Microchip Technology PIC16LF1934T-I/MV is an 8-bit PIC microcontroller delivering 32 MHz CPU performance with 7 KB of Flash program memory, 256 bytes of EEPROM, and 256 bytes of SRAM, all housed in a 40-pin UQFN (MV) package measuring 5x5 mm. It is part of the PIC16LF193x family that combines a 14-bit instruction set with nanoWatt XLP (eXtreme Low Power) technology to extend battery life in energy-harvesting and portable designs. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, RAM, and peripherals on a single die; the PIC16 family uses a RISC-based Harvard architecture with a 14-bit instruction word optimized for deterministic interrupt latency and low code density. Within the broader microcontroller taxonomy, 8-bit MCUs sit below 16-bit and 32-bit cores in raw throughput but dominate cost-sensitive and ultra-low-power applications where every microwatt of quiescent current matters. Key features include 35 digital I/O lines, five 8-bit timers plus one 16-bit timer, a 10-bit ADC with up to 14 channels, two comparators, five PWM modules with capture/compare, an EUSART for asynchronous serial, two I2C/SPI MSSP peripherals, and a capacitive touch mTouch peripheral. The nanoWatt XLP technology drops quiescent current to roughly 50 nA in sleep mode and below 1 µA in real-time-clock operation from a 1.8 V supply, supporting multi-year coin-cell life. The device is built on a CMOS process with a wide 1.8 V to 3.6 V supply range and operates across -40 °C to +85 °C industrial temperatures. Its integrated LCD driver supports up to 96 segments, enabling direct glass drive without an external charge-pump or controller. On-chip peripherals like the 32 kHz oscillator timer, brown-out reset (BOR), and watchdog timer reduce external component count for compact sensor and user-interface modules. Typical applications include small home-appliance keypads, battery-powered sensor nodes, consumer remote controls, low-cost instrumentation front-ends, capacitive-touch human-machine interfaces, and white-goods or HVAC user-interface boards. Designers choose the PIC16LF1934 for its combination of integrated LCD, mTouch, and very low sleep current in a compact 40-pin QFN footprint. When designing with this MCU, ensure decoupling capacitance is placed within 5 mm of VDD/AVDD and that the exposed pad (EP) is soldered to a properly grounded copper pour to meet thermal and electrical performance. Use the MPLAB X IDE with the XC8 compiler and PICkit or ICD programmer to debug and program the device in-circuit.
