The XLP variants add nanoWatt sleep modes and ultra-low standby currents, enabling years of operation from coin-cell or primary batteries. Core Independent Peripherals (CIPs) like the Hardware Limit Timer (HLT) and Windowed Watchdog Timer (WWDT) execute logic without CPU intervention, freeing the core and reducing active power. Key features include integrated LCD drive (up to 96 segments) with on-chip charge pump, four 16-bit timers, four CCP/ECCP plus CWG peripherals, Peripheral Pin Select (PPS) for flexible signal routing, and an RTCC with calendar mode. CRC/SCAN hardware supports non-intrusive memory integrity checks. The device is supported by Microchip's MPLAB X IDE, XC8 compiler, and MCC code configurator, providing a complete firmware development chain from prototype through production. Typical applications include battery-powered LCD consumer products such as thermostats, electronic shelf labels, blood glucose meters, and remote controls. Industrial HMI panels, sensor node data loggers, and metering front-ends also benefit from its rich peripheral set and low sleep current. The integrated 12-bit ADC2 and 5-bit DAC simplify analog signal conditioning in measurement products without requiring external components. When designing with this device, plan the pinout using the Peripheral Pin Select (PPS) feature, which remaps digital peripherals to a wide range of I/O pins. Decouple VDD with a 0.1 uF X7R ceramic placed within 3 mm of the package, and place the VCAP pin capacitor (1 uF to 10 uF) as close as possible to maintain LDO stability. Always configure unused I/O as outputs low to minimize current leakage in sleep mode.

PIC16LF19176T-I/PT - 8-bit XLP MCU, 28KB Flash, 32MHz | Microchip

The Microchip PIC16LF19176T-I/PT is a low-power 8-bit PIC16 microcontroller built on the enhanced mid-range core, delivering 32 MIPS at 32 MHz, 28 KB of Flash program memory, 2 KB of RAM, and 256 bytes of EEPROM, housed in a 44-pin TQFP (10x10 mm) package. Its headline features are eXtreme Low-Power (XLP) operation from 1.8 V to 3.6 V, an integrated segmented LCD driver with charge pump, a 12-bit ADC2 with Computation, a 5-bit/10-bit DAC, multiple Core Independent Peripherals (CIPs) including CWG, CCP, PWM, SMT, ZCD, PPS, and a Real-Time Clock/Calendar (RTCC). The part comes in tape-and-reel packaging suitable for high-volume SMT assembly. Microcontrollers are programmable embedded computing devices that integrate a CPU, memory, and peripherals onto a single silicon die. Within that hierarchy, an 8-bit MCU like the PIC16LF19176 belongs to the PIC16 family of microcontrollers, which is a sub-family of the larger PIC microcontroller line, itself a major branch of the embedded microcontroller (MCU) product category, ultimately classified under integrated circuits and semiconductors. Engineers pick 8-bit MCUs when cost, deterministic interrupt response, and low power outweigh the raw throughput of 32-bit cores. This device targets battery-powered human-machine interfaces. XLP technology gives typical deep-sleep currents in the nanoamp range (per the datasheet IDD/DATA specifications), while the LCD charge pump supports glass types that require voltage rails above VDD. On-chip 12-bit ADC2 with oversampling and Burst Accumulate modes reduces external signal-conditioning cost; the DAC enables setpoint generation without a separate chip. The CIPs - Configurable Logic Cell (CLC), Complementary Waveform Generator (CWG), Signal Measurement Timer (SMT), and Zero-Cross Detect (ZCD) - let timing- and waveform-sensitive functions run without CPU intervention, freeing the core for application code. Peripheral Pin Select (PPS) provides flexible digital I/O mapping across 35 I/O pins, easing PCB routing for mixed-signal boards. Typical applications include battery-powered consumer products with segmented LCDs (thermometers, blood-pressure monitors, remote controls), industrial sensor transmitters, IoT edge nodes, white-goods user interfaces, and metering/utility devices that demand long battery life and integrated analog signal chains. When designing with this part, verify the chosen package variant against board space early: the 44-pin TQFP in this MPN is the largest of the family, providing the most I/O; smaller 28-pin or 40-pin variants may require remapping signals. Also confirm the operating voltage window supports your LCD bias requirements, since some glass choices drive VDD toward the upper 3.6 V limit.

Architecturally the device uses a Harvard memory layout with separate program flash and SRAM buses, hardware stack, and 31 kHz LFINTOSC plus 16 MHz HFINTOSC internal oscillators. The internal voltage reference and charge pump allow display operation from a single 1.8-3.6V supply. Intelligent analog integration (ADC2 with oversampling and filtering) reduces the external signal-conditioning BOM. Typical applications include battery-powered IoT sensor nodes with LCD displays, electronic shelf labels, medical glucose/thermometer meters, portable consumer appliances, and industrial HMI panels. The wide operating range and integrated LCD make it ideal for any mains-or-battery product that needs a segmented display without an external driver IC. When designing, reserve adequate decoupling (100 nF + 1 uF) close to VDD/AVDD pins, and follow Microchip AN1365 (LCD layout) for the SEG/COM routing to minimize ghosting.

PIC16LF19196-E/5LXVAO

PIC16LF19196-E/5LXVAO - 28KB Flash 8-bit XLP LCD MCU | Microchip

The Microchip Technology PIC16LF19196-E/5LXVAO is an 8-bit PIC16 XLP flash microcontroller featuring 28KB (16K x 14) of program memory, 2KB of SRAM, and 256 bytes of EEPROM in a 64-pin VFQFN exposed-pad (9x9) package. It operates from a wide 1.8V to 3.6V supply, includes an integrated LCD driver with charge pump, and supports AEC-Q100 automotive-grade qualification for safety-critical applications. The device runs the enhanced mid-range PIC16 CPU at up to 32MHz and provides a rich Core Independent Peripheral (CIP) set for low-power, mixed-signal designs. A microcontroller is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory (SRAM), and a configurable set of digital and analog peripherals. Within the broader taxonomy, the PIC16LF19196 sits in the PIC16 mid-range family -> 8-bit RISC microcontroller -> MCU -> embedded microcontroller -> semiconductor. Compared with 16-bit or 32-bit Cortex-M parts, an 8-bit PIC16 lowers cost, code complexity, and active current, while still providing enough throughput for sensor hubs, HMI, and battery-powered LCD applications. Key differentiating features include Microchip's eXtreme Low-Power (XLP) technology with deep-sleep currents below 1 uA, an integrated LCD charge pump that simplifies glass drive from a single lithium cell, and CIP analog blocks such as 12-bit ADC, 5-bit DAC, comparators, and zero-cross detection. The 64-VQFN footprint with exposed pad supports thermally robust layouts for high-current I/O segments and reduces PCB area versus 64-pin TQFP when board real estate is constrained. On the architecture side, the PIC16LF19196 combines a 14-bit instruction word, a hardware multiplier, and a peripheral pin-select (PPS) engine that allows remapping of digital functions to optimize PCB routing. The 32MHz oscillator with 4x PLL equivalent provides deterministic interrupt latency critical for motor control loops, while the integrated charge pump and high-current I/O eliminate external DC-DC and segment-driver components in LCD user interfaces. Typical applications include battery-powered LCD thermostats, IoT sensor nodes with always-on displays, automotive dashboard indicators, medical infusion pumps, metering and instrumentation with segment LCDs, and ultra-low-power HMI keypads. The combination of XLP sleep current and integrated LCD drive makes the part especially attractive for products that need years of coin-cell life with a live alphanumeric or graphical segment display. When designing with this part, ensure the exposed pad is soldered to a sufficient copper pour (at least 1 square cm) so junction temperature stays within the -40C to +125C automotive range under full I/O loading. The PPS feature should be assigned early in the schematic to avoid pin-function conflicts in the 64-VQFN footprint, and unused pins must be tied to defined logic states (not left floating) for robustness in AEC-Q100 systems. This page consolidates distributor pricing, automotive-grade drop-in alternates, and design notes that complement the manufacturer datasheet for engineers sourcing automotive-grade PIC16 XLP LCD microcontrollers.

PIC16LF19196-E/PT

PIC16LF19196-E/PT - 8-bit 32MHz XLP LCD MCU 28KB Flash | Microchip

The Microchip Technology PIC16LF19196-E/PT is an 8-bit PIC16 microcontroller from the XLP family that combines eXtreme low-power operation with integrated LCD drive and Core Independent Peripherals (CIPs), housed in a 64-pin TQFP (10x10 mm) package. It runs at up to 32 MHz, integrates 28 KB of Flash program memory (16K x 14 words), 2 KB of RAM, and 256 bytes of EEPROM, and supports 59 digital I/O lines for sensor and user-interface connectivity. The -E suffix designates the -40C to +125C extended operating temperature range required for industrial and automotive-grade applications. An 8-bit PIC microcontroller is a RISC-based, Harvard-architecture embedded processor that executes one instruction per clock cycle (except branches) and is positioned in Microchip's product hierarchy as PIC -> PIC16 -> PIC16F19xx -> XLP family. 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.
