PIC16F19156T-I/SO - 28KB Flash XLP MCU with LCD | Microchip

The Microchip Technology PIC16F19156T-I/SO is an 8-bit PIC microcontroller featuring 28KB of Flash program memory, 2KB of RAM, and 256 bytes of EEPROM, housed in a 28-pin SOIC package. It operates at up to 32 MHz with a 3V supply and integrates Xtreme Low-Power (XLP) technology, an LCD driver with integrated charge pump, and core independent peripherals including a 12-bit ADC2, DAC, low-power comparator, PWM, CCP, CWG, SMT, ZCD, PPS, and RTCC. What is an 8-bit microcontroller? An MCU (microcontroller unit) is a single-chip computer that integrates a CPU core, program memory, working RAM, non-volatile data EEPROM, and a rich set of mixed-signal peripherals. 8-bit MCUs use an 8-bit data path and are favored for deterministic real-time control, ultra-low sleep current, and low BOM cost. The PIC16 family sits between PIC10/PIC12 baseline parts and PIC18/PIC24 mid-range parts, occupying the XLP sweet spot for battery-powered and human-machine interface designs. Key features include eXtreme Low-Power (XLP) operation suitable for battery-powered applications, an integrated charge pump that generates LCD bias voltages directly from a single Li-ion cell, high-current I/O pins for direct LED drive, and Core Independent Peripherals (CIPs) that offload timing-critical tasks from the CPU. The device also offers Peripheral Pin Select (PPS) for flexible signal routing and a 12-bit ADC2 with computation. Architecturally, the PIC16F19156T-I/SO uses a RISC Harvard-bus core with a hardware multiplier, executes most instructions in a single cycle, and provides a vectored interrupt controller. The integrated LCD driver supports up to a defined segment count and runs from an internal charge pump so no external bias network is needed. Typical applications include battery-powered LCD dashboards, smart thermostats, IoT sensor nodes with displays, medical glucose and infusion meters, consumer white goods with segment displays, and industrial HMI panels. The wide operating voltage range down to below 2V and nanoWatt sleep modes make it ideal for any product that must run for years on a single battery while driving an LCD. When designing with this part, plan decoupling with a 100 nF ceramic bypass close to VDD, and follow the recommended LCD bias capacitor values from the datasheet to avoid ripple on the display. Use the Peripheral Pin Select feature to remap peripherals and keep PCB layout changes minimal when porting from older PIC16 designs.

PIC16F19175-I/MV

PIC16F19175-I/MV - 14KB Flash 8-bit XLP LCD MCU | Microchip

The Microchip Technology PIC16F19175-I/MV is an 8-bit PIC microcontroller from the PIC16F191xx family that pairs eXtreme Low-Power (XLP) operation with integrated LCD drive and Core Independent Peripherals, delivered in a 40-pin UQFN (MV) package measuring 5x5 mm. The device integrates 14 KB of Flash program memory, 1 KB of SRAM, and 256 bytes of EEPROM, and runs at speeds up to 32 MHz. Its on-board analog includes a 12-bit ADC2 with computation, a 5-/8-bit DAC, low-power comparators, zero-cross detection, and a charge-pump-assisted LCD driver capable of up to 280 segments. Background: A PIC microcontroller is an 8-bit RISC-class embedded processor built around a Harvard architecture with separate program and data buses, executing one instruction per clock cycle and supported by a rich set of Core Independent Peripherals (CIPs) that operate without CPU intervention. PIC microcontrollers sit within the broader hierarchy: microcontroller -> embedded processor -> semiconductor, and are widely used in ultra-low-power battery applications where deterministic behaviour and low quiescent current are critical. The XLP designation signals a part optimised for sub-uA sleep currents, making it a member of the power management ecosystem at the device level. Key features include active current consumption in the microamp range, multiple low-power sleep modes (doze, idle, sleep), an integrated LCD charge pump that maintains contrast down to 1.8 V, and high-current I/O pins suitable for direct LED drive. The 12-bit ADC2 with averaging and accumulation, combined with the on-chip 5-/8-bit DAC and zero-cross detect, supports intelligent analog front-ends for sensor conditioning and motor control without external components. Technical depth: the CIP block includes Complementary Waveform Generator (CWG), Configurable Logic Cell (CLC), Signal Measurement Timer (SMT), PWM, CCP, and Peripheral Pin Select (PPS), allowing timing-critical logic to run autonomously while the CPU sleeps. PPS remaps most digital peripherals to a wide choice of I/O pins, simplifying PCB routing on dense mixed-signal boards. Typical applications span battery-powered LCD keypads, IoT sensor nodes, consumer white goods with LCD displays, and portable medical monitors requiring long standby time. The integrated LCD charge pump makes it ideal when the system must display information down to a nearly discharged battery. When designing with this part, prefer PPS to route peripherals to the most convenient pins and exploit CIPs so the CPU can spend most of its time in sleep. Always validate sleep current against the application budget; the XLP spec is best realised when wake-up events are driven by CIPs rather than interrupts.

It operates at up to 32 MHz, integrates 14 KB of Flash program memory (8K x 14 words), 1 KB of SRAM, and 256 B of EEPROM, and is housed in a 64-pin TQFP (PT, 10x10 mm) package with automotive-grade -40C to +125C operating temperature range. The device also features an integrated charge pump for LCD bias generation, high-current I/O drive for direct LED backlight control, and battery backup of the on-chip Real-Time Clock/Calendar (RTCC). What is an XLP microcontroller? An XLP (eXtreme Low-Power) microcontroller is a class of MCU specifically architected for battery-powered and energy-harvesting applications. The hypernym hierarchy is: microcontroller -> MCU -> embedded controller -> semiconductor. XLP devices combine multiple low-power modes (sleep, deep sleep, doze, idle) with peripheral clock gating and ultra-low quiescent current, often below 1 uA in deep sleep. The PIC16F19195 adds a segmented LCD driver, making it a single-chip solution for battery-powered human-machine interfaces in metering, medical, and consumer devices. Key differentiating features include the integrated LCD driver with charge pump, eliminating external bias-voltage circuitry; 12-bit ADC2 with computation, 5-bit DAC, and low-power comparators providing intelligent analog signal conditioning; and Core Independent Peripherals (CIPs) such as CWG, CCP, PWM, ZCD, and SMT that operate without CPU intervention. The Peripheral Pin Select (PPS) feature allows flexible remapping of digital peripherals to I/O pins, simplifying PCB layout. Architecturally, the PIC16F19195 uses an enhanced mid-range 8-bit CPU core with a hardware stack, hardware multiplier, and instruction prefetch. The device supports ICSP (In-Circuit Serial Programming) and debug, enabling field upgradability. The PMD (Peripheral Module Disable) registers and HLT (Hardware Limit Timer) further extend battery life by allowing firmware to power down peripherals when not in use. Typical applications include battery-powered blood glucose meters, electronic shelf labels, smart thermostats, portable medical monitors, and any product combining a low-power MCU with a segmented LCD user interface. The high-current I/O (up to 100 mA per pin) can also directly drive small LED backlights without external transistors. Design consideration: when migrating firmware between PIC16F19195, PIC16F19196, and PIC16F19197 variants, verify that the target pin count and memory size are compatible. The -E suffix denotes the extended -40C to +125C industrial/automotive temperature grade; -I variants operate from -40C to +85C.

PIC16F19195T-I/MR

PIC16F19195T-I/MR - 8-bit XLP MCU, 14KB Flash, 64-QFN | Microchip

The Microchip Technology PIC16F19195T-I/MR is an 8-bit PIC microcontroller from the PIC16F191xx family featuring eXtreme Low-Power (XLP) technology, an integrated LCD driver, and Core Independent Peripherals (CIPs), housed in a 64-pin QFN (9x9 mm) package with exposed thermal pad. The device runs at up to 32 MHz, delivers 14 KB (8K x 14 words) of Flash program memory, 1 KB of RAM, and 256 bytes of EEPROM, and integrates an intelligent analog block with 12-bit ADC, DAC, and low-power comparators. An 8-bit PIC microcontroller (MCU) is a Harvard-architecture embedded controller that executes one byte-wide instruction per cycle from internal Flash, providing deterministic real-time response in cost-sensitive applications. Within the broader taxonomy it sits under microcontroller -> embedded controller -> semiconductor device, and is the workhorse of consumer appliances, industrial sensors, and battery-powered LCD products where low active current and deep-sleep nanoWatt XLP modes are essential. Key features include operation from 1.8V to 5.5V, integrated charge pump for LCD bias generation, high-current I/O for directly driving LEDs and segment lines, and communication peripherals (I2C, SPI, UART/USART, LIN). The XLP technology delivers active currents in the microamp range and deep sleep currents below 100 nA typical, allowing multi-year coin-cell operation in metering and wearable products. Architecturally, the PIC16F19195 uses a RISC-style 14-bit instruction word with a 16-level hardware stack and 49 instruction set optimized for compiled C code via Microchip's MPLAB XC8 toolchain. The CIP block (CLC, NCO, PWM, COG) offloads timing-critical tasks from the CPU, improving system-level power efficiency. Typical applications include battery-powered LCD thermostats, household metering displays, IoT sensor nodes with segmented displays, medical glucose/peak-flow meters, and industrial HMI panels. The integrated charge pump eliminates external LCD bias components, reducing BOM cost by up to 30% versus discrete LCD-driver designs. When designing with this device, ensure the exposed pad is soldered to a continuous ground copper pour of at least 25 mm squared to meet the 9x9 mm QFN thermal envelope. Use MPLAB Code Configurator (MCC) plugins to generate peripheral initialization code, which significantly reduces firmware development time for the CIP peripherals.

PIC16F19196-E/PT

PIC16F19196-E/PT - 8-bit XLP LCD MCU 28KB Flash 64-TQFP | Microchip

The Microchip Technology PIC16F19196-E/PT is an 8-bit PIC® XLP™ microcontroller with 28KB (16K x 14) of Flash program memory, packaged in a 64-pin TQFP (10x10 mm) form factor with extended (-40C to +125C) operating range. It executes instructions at up to 32MHz from the enhanced mid-range core and integrates Core Independent Peripherals (CIPs) and Intelligent Analog, including a 45-channel 12-bit ADC and a 5-bit DAC. The 'E' suffix denotes the industrial/extended temperature grade and the 'PT' suffix marks the 64-pin TQFP package. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a rich set of peripherals. The PIC16F19196 belongs to the broader PIC16F1xxx family, which itself is part of Microchip's 8-bit PIC microcontrollers category, positioned for ultra-low-power (XLP) and battery-friendly designs. Within an embedded system hierarchy it sits beneath application processors and above bare-metal timer ICs, providing deterministic real-time control alongside human-interface and analog signal conditioning. Key features include eXtreme Low-Power (XLP) operation with a claimed standby current in the nanoamp range (per the manufacturer datasheet), an integrated charge pump that maintains regulated LCD bias even when VDD droops, high-current I/O capable of directly driving LCD backlighting, and battery backup of the on-chip Real-Time Clock/Calendar (RTCC). Additional peripherals include a low-power comparator, PWM, CCP, CWG, SMT (Signal Measurement Timer), ZCD (zero-cross detect), PPS (Peripheral Pin Select), Windowed Watchdog Timer (WWDT), HLT (Hardware Limit Timer), and Peripheral Module Disable (PMD) for power gating unused functions at runtime. Architecturally, the part uses Microchip's 8-bit modified Harvard core with a 14-bit instruction word, hardware multiplier, and an interrupt controller. The LCD driver supports up to 384 segments with charge-pump bias generation. The 12-bit ADC2 block delivers differential and single-ended conversions with hardware averaging. The RTCC can be retained from a backup coin cell while the main VDD rail is removed, enabling calendar functions across battery swaps. Typical applications include battery-powered thermostats and HVAC controllers, home-appliance user interfaces with LCD, wearable fitness and medical monitors, e-metering and utility displays, and rugged industrial sensor readouts with LCD. The wide operating temperature and ultra-low standby current also suit automotive aftermarket products and remote IoT endpoints that must run for years on a single cell. A key design consideration is leveraging the PMD registers to disable peripherals that are not in use, and using the charge pump to keep the LCD contrast constant as VDD discharges. Designers should also plan the PPS routing early, since most digital peripherals can be mapped to multiple pins on this family.
