The 'LF' in the part number indicates the low-power F-version core, which supports lower Vdd operation than the standard F variant, while 'XLP' (eXtreme Low Power) is Microchip's branded low-power technology family targeting battery-powered and energy-harvesting designs. The integrated charge pump and high-current I/O make this sub-family especially suited for battery-powered LCD applications where discrete LCD bias generation would otherwise inflate BOM cost. Key features include a 12-bit ADC with computation (ADC2), a 5-bit/10-bit DAC, low-power comparators (LP COMP), PWM, CCP, CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), ZCD (Zero-Cross Detect), Peripheral Pin Select (PPS), RTCC (Real-Time Clock Calendar), Hardware Limit Timer (HLT), Windowed WWDT, and PMD (Peripheral Module Disable). The 32 MHz internal oscillator plus integrated LCD driver (up to 288 segments) make this part well suited for low-power graphical or segment LCD products. Technical depth: the LF core operates from 1.8 V to 3.6 V (down to 1.8 V at 16 MHz, 2.5 V to 3.6 V at 32 MHz) with a typical sleep current in the nanoampere range thanks to XLP technology. The 12-bit ADC2 provides automated averaging, accumulation and threshold comparison without CPU intervention (CIP), freeing the core for power management tasks. PPS allows most digital peripherals to be remapped to a wide selection of I/O pins, simplifying PCB routing on densely-populated 64-pin designs. Typical applications include battery-powered medical devices, industrial sensor transmitters, IoT edge nodes, home-automation HMI panels, smart thermostats, and low-power metering. The integrated LCD driver makes it especially attractive for appliances and instruments with segment displays. Design consideration: pair the MCU with a CR2032 or two AA cells via a boost regulator to leverage XLP sleep currents below 1 uA; verify LCD contrast across temperature and confirm PPS mapping for all peripherals during firmware bring-up.

PIC16LF19196-I/PT

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 - 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.

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.

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. Route the analog VDD/VSS pair separately from the digital supply to preserve ADC accuracy. This page combines manufacturer specification data, distributor pricing snapshots and curated drop-in alternatives to help engineers evaluate the PIC16LF1933-E/MV against competing 8-bit LCD MCUs in the same UQFN-28 footprint.

PIC16LF1933-E/SP - 8-bit MCU 7KB Flash 32MHz XLP | Microchip

The Microchip Technology PIC16LF1933-E/SP is an 8-bit CMOS flash-based microcontroller from the PIC16F193X/LF193X family featuring nanoWatt XLP extreme-low-power technology, 7KB (4K x 14 words) of flash program memory, 256 bytes of RAM and 256 bytes of EEPROM, packaged in a 28-pin SPDIP (0.300 inch, 7.62 mm) through-hole DIP with a 32 MHz internal oscillator and a 1.8 V to 5.5 V operating voltage range. 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. This page synthesizes distributor availability, verified specifications, drop-in same-package alternatives, and practical design notes beyond what the manufacturer datasheet alone provides.

PIC16LF1933-I/ML - 8-bit XLP MCU, 7KB Flash, LCD Driver | Microchip

The Microchip Technology PIC16LF1933-I/ML is an 8-bit CMOS flash microcontroller built on the enhanced mid-range PIC16 core, delivering 7 KB of Flash program memory, 256 bytes of SRAM and 256 bytes of EEPROM in a 28-pin VQFN (ML, 6x6 mm) package. It runs up to 32 MHz instruction rate at 1.8V to 5.5V with nanoWatt XLP extreme-low-power technology for battery-friendly designs. The integrated LCD driver supports up to 96 segments, eliminating external display controllers. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, RAM, EEPROM and a rich set of peripherals (ADC, timers, communications, I/O) onto one die. PIC16-family parts sit at the low-power, low-cost end of the embedded tree: PIC16 -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The LF sub-family is specifically engineered for ultra-low active and sleep currents (nanoWatt XLP), making PIC16LF1933 parts common in battery-powered human-interface and metering products. Key features of this part include 7 KB (4K x 14) self-read Flash with ICD, 256 B RAM, 256 B EEPROM, an on-chip 32 MHz internal oscillator, 11-channel 10-bit ADC, four timers (Timer0/1/2/6), enhanced CCP, AUSART, SSP/SPI/I2C, mTouch capacitive sensing, a charge-pump LCD driver (96 segments), up to 25 I/O pins, and nanoWatt XLP sleep currents down to a few nA. The 28-VQFN package supplies an exposed thermal pad for improved dissipation in compact modules. Architecturally, the device uses a RISC-style Harvard bus with a 14-bit instruction word, 16-level hardware stack and 49-instruction set, providing deterministic 200 ns minimum instruction execution at 20 MHz and 125 ns at 32 MHz. The internal 32 MHz HFINTOSC plus 31 kHz LFINTOSC let designs run without external crystals, while the LCD charge pump keeps the display contrast stable down to 1.8V supply rails. Typical applications include low-power human-interface products such as thermostat/HVAC front panels, battery-powered medical monitors (glucose meters, pulse oximeters), consumer remote controls with LCD, electronic shelf labels, utility metering endpoints, and industrial sensor nodes. The combination of LCD driver, eXtreme Low Power and 28-VQFN small footprint is what engineers select this part for. When designing with this device, budget the I/O count carefully - the 28-pin QFN exposes 25 I/O, but several pins are multiplexed with the LCD segment driver; reserve dedicated pins for the LCD charge pump and bias network to avoid display flicker on low VDD rails. The ICSP/ICD pins (ICSPCLK/ICSPDAT) must be reachable on the PCB for in-circuit debugging. This page consolidates distributor pricing, drop-in VQFN-28 alternatives, comparison vs PIC16F1933 and PIC16F1825, and practical design notes that supplement the manufacturer datasheet.

PIC16LF1933-I/MV - 8-bit 32MHz XLP MCU 7KB Flash | Microchip

The Microchip Technology PIC16LF1933-I/MV is an 8-bit Flash-based CMOS microcontroller from the PIC16F193X/LF193X family, featuring 7KB (4K x 14) of Flash program memory, 256 bytes of RAM, and 256 bytes of EEPROM, operating at up to 32 MHz internal oscillator speed, housed in a 28-pin UQFN (4x4 mm) package. The 'LF' suffix denotes the low-power variant using Microchip's nanoWatt XLP (eXtreme Low Power) technology, drawing nanoamp-level sleep currents, while the -I suffix indicates the industrial -40C to +85C operating temperature range. A PIC microcontroller is a microcontroller unit (MCU) based on Microchip's proprietary PIC (Peripheral Interface Controller) RISC architecture, widely used in embedded systems for sensor interfacing, control loops, and human-machine interfaces. The PIC16 family sits within the broader taxonomy of 8-bit microcontrollers, which represent the entry-level tier of MCU complexity versus 16-bit (MSP430, PIC24) and 32-bit (ARM Cortex-M) cores. The PIC16LF1933 specifically targets low-power applications needing integrated peripherals without external component count. Key differentiating features include a 60-segment LCD driver, integrated capacitive mTouch sensing module, internal 32 MHz oscillator, integrated temperature indicator, and 12-bit ADC with computation. Communication peripherals include I2C, SPI, and EUSART with auto-baud, while motor-control support comes from 3 Enhanced CCP and 2 standard CCP modules. The 28-pin UQFN package provides 25 I/O pins with individual pull-ups, interrupt-on-change, and programmable weak pull-ups. The device uses an enhanced mid-range 14-bit instruction set with 49 instructions and 16-level hardware stack, providing deterministic 200ns instruction execution. The XLP technology adds deep sleep, watchdog, and RTCC modes enabling years of battery life in IoT sensor nodes. Power-on reset, brown-out detect, and an extended watchdog timer with dedicated on-chip oscillator add to system robustness. Typical applications include battery-powered IoT sensor nodes, LCD-based consumer appliances, capacitive touch human-machine interfaces, low-power remote controls, and industrial metering equipment. The combination of integrated LCD driver and nanoWatt XLP makes it particularly suitable for battery-powered thermostats, blood pressure monitors, and electronic shelf labels. Compared to discrete logic, this MCU reduces BOM count by integrating oscillator, voltage reference, ADC, and LCD bias generation. Design consideration: the 28-UQFN package has an exposed thermal pad that must be soldered to the PCB ground pour for proper thermal and electrical performance. For lowest sleep current, disable all unused peripherals via the PMD registers and use the deep sleep mode with RTCC running from a 32 kHz external crystal.
