PIC16LF1903-E/MV - 8-bit LCD MCU 7KB FLASH XLP 28-UQFN | Microchip

The Microchip Technology PIC16LF1903-E/MV is a 8-bit PIC® XLP™ flash microcontroller with integrated LCD driver, featuring 7KB (4K x 14) of self-read/write flash program memory, 256 bytes of RAM, and 128 bytes of non-volatile data EEPROM, all housed in a 28-pin UQFN (4x4 mm) package with exposed pad. It operates at up to 20 MHz from a 1.8V to 3.6V supply and is qualified to the -40°C to +125°C extended industrial temperature range. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/Flash), data memory (RAM), and programmable I/O peripherals on one silicon die. The PIC16F family uses Microchip's enhanced mid-range core with 49 instructions, 16-level hardware stack, and nanoWatt XLP™ ultra-low-power technology. Within the broader semiconductor taxonomy, an MCU sits below microprocessors and above digital logic ICs, intended for embedded control tasks rather than general-purpose computation. Integrated LCD segment drivers and ADC peripherals allow a single MCU to drive both the user interface and the analog sensor chain in small, battery-powered products. Key features of the PIC16LF1903 include 11 channels of 10-bit ADC with voltage reference, integrated temperature indicator, 72-segment LCD driver, 25 mA source/sink I/O, internal 16 MHz oscillator, two timers (one 8-bit TMR0, one 16-bit TMR1), an Enhanced Watchdog Timer (EWDT) with on-chip low-power oscillator, brown-out reset, and nanoWatt XLP sleep currents in the sub-microamp range. The UQFN-28 4x4 mm footprint with exposed thermal pad supports compact handheld and wearable layouts where PCB area is at a premium. The PIC16LF1903 architecture pairs the enhanced mid-range core with on-chip LCD charge-pump segment drivers, allowing direct glass connection without external resistor bias trees. The 16 MHz internal oscillator trims out an external crystal in most cost-sensitive designs, while 128 B EEPROM supports non-volatile user-set parameters without external serial EEPROM chips. Sleep currents below 1 µA enable coin-cell and energy-harvesting applications where quiescent draw dominates battery life. Typical applications include battery-powered LCD thermostats, metering displays, medical pumps with segment LCDs, white-goods front panels, electronic shelf labels, IoT sensor nodes with local display readouts, and remote controls with multi-segment LCDs. Designers choose this part when they need up to 72 LCD segments plus ADC sensing in a 4x4 mm package. When designing with the PIC16LF1903, ensure the LCD bias network is correctly configured for the panel type (static, 1/2, 1/3, 1/4 duty) and that the exposed pad is soldered to a sufficiently large copper pour to keep junction temperature in spec. Use MPLAB X IDE with XC8 compiler for code development; ICD/debug requires two I/O pins allocated to ICDCLK and ICDDAT.

It belongs to the PIC16LF1902/1903 family, which uses Microchip's enhanced mid-range core with 49 instructions and 16 stack levels and runs at up to 16 MHz internal clock. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash program, SRAM data, and EEPROM), and programmable peripherals. PIC microcontrollers use Microchip's proprietary RISC architecture and are widely deployed in cost-sensitive embedded designs. Within the PIC16 family hierarchy, the LF prefix denotes the low-power (XLP, "eXtreme Low Power") variant optimized for battery-powered applications. The PIC16LF1903 sits at the small-memory end of the family, trading larger flash and SRAM for lower cost, while retaining the LCD driver peripheral that makes it attractive for human-interface products. Key features include 11 channels of 10-bit ADC with voltage reference, an internal 16 MHz oscillator, an integrated temperature indicator, 25 mA source/sink I/O drive, one 8-bit timer (TMR0), one 16-bit timer (TMR1), an extended watchdog timer (EWDT), brown-out reset, 128 bytes of non-volatile data storage (EEPROM), and 72 LCD segment drive support. The "E" temperature grade extends operation from -40 °C to +125 °C, suiting automotive and industrial environments. The PIC16LF1903 uses flash memory with self read/write capability and supports in-circuit serial programming (ICSP) plus in-circuit debugging via PICkit 3 or MPLAB ICD 3 with the optional AC244048 debug header. The C compiler toolchain is MPLAB X IDE with XC8, free for the standard optimization level, which lowers the firmware development barrier for hobbyist and small-volume production use. Typical applications include battery-powered consumer devices with segment LCDs (thermostats, kitchen scales, remote controls, glucometers), industrial sensor front-ends with on-glass LCD readouts, low-cost metering, and simple HMI panels. The combination of LCD driver, ADC, and XLP nanoWatt technology removes the need for an external display driver IC in many designs. Design consideration: the 28-pin SOIC (SO) wide-body footprint is the most common package for this family. Verify that your PCB layout supports the LCD segment routing requirements — typically 4 common lines and up to 18 segment lines — and budget quiescent current carefully if the design will sleep for long intervals. This page synthesizes Microchip datasheet specifications, current distributor pricing, and drop-in alternatives that share the 28-SOIC footprint, providing information not aggregated on any single distributor page.

An 8-bit microcontroller (MCU) is a single-chip processor with an 8-bit data path, on-board program memory, RAM, and integrated peripherals such as timers, ADC, and communication interfaces. 8-bit MCUs sit at the base of the microcontroller hierarchy (8-bit -> 16-bit -> 32-bit MCU -> embedded processor -> semiconductor IC) and dominate ultra-low-power, cost-sensitive, and human-interface applications where a small instruction set, deterministic timing, and picoamp-range sleep currents matter more than raw compute throughput. Microchip's PIC16F enhanced mid-range core combines RISC performance (49 instructions, 16 stack levels) with the company's proprietary eXtreme Low Power (XLP) technology, allowing battery-powered products to run for years on a single cell. Key differentiating features include the on-chip LCD segment driver (up to 72 segments), which eliminates external driver ICs and BOM cost in meter and appliance displays, and the 11-channel 10-bit ADC with a dedicated voltage reference and integrated temperature indicator - enabling sensor readout and on-die thermal monitoring from a single analog pin network. The XLP sleep current and wide 1.8V-3.6V operating range make the part suitable for direct Li-ion or 2x AA battery connection without external regulation. The PIC16LF1903 architecture pairs an enhanced mid-range CPU core with self-read/write flash, allowing field firmware updates and EEPROM-style data logging in the 128 B non-volatile data store. The integrated 16 MHz high-precision internal oscillator removes the need for an external crystal in cost-sensitive designs, while the brown-out reset and extended watchdog timer provide robust recovery from power and code-flow anomalies. CoreMark-independent benchmarks show the 49-instruction RISC core delivers predictable interrupt latency critical for control loops. Typical applications include battery-powered consumer products (thermostats, remote controls, toys), small home appliances with LCD panels (microwave ovens, coffee makers, washing machine front panels), industrial sensor transmitters, metering (electricity/water/gas meters with segment LCDs), and low-cost IoT edge nodes. Designers pick this part when the application needs a long battery life, an integrated LCD, and 8-bit simplicity rather than connectivity stacks. When designing with the PIC16LF1903-E/SS, always consult Microchip's MPLAB X IDE and XC8 compiler toolchain for code generation, and reserve one ICD pin pair for in-circuit debug. For LCD designs, follow Microchip Application Note AN649 "LCD Biasing and Contrast" to bias the segment pins correctly and avoid ghosting. Decouple VDD with at least 100 nF plus a bulk capacitor, and keep analog traces short to preserve ADC accuracy.

Key features include 14KB self-programmable Flash, 256 bytes of EEPROM, an integrated LCD driver with charge pump and contrast control, an ADC with 10-bit resolution and multiple channels, two comparators, PWM modules, and multiple communication peripherals including EUSART, I2C, and SPI. The LF designator indicates low-voltage (1.8V-3.6V) operation optimized for battery-powered applications. The PIC16LF1907 employs a Harvard-architecture RISC core with a 14-bit instruction word. nanoWatt XLP technology integrates deep-sleep, sleep, and doze power modes plus a watchdog timer that can run from an ultra-low-power internal oscillator. The 40-UQFN package exposes an exposed thermal pad to maximize heat dissipation in surface-mount designs. Typical applications include battery-powered LCD-based consumer electronics (thermostats, scales, metering), portable instrumentation, IoT sensor nodes, low-power remote controls, and home appliances where an integrated LCD driver reduces bill-of-materials cost. When designing with this part, ensure the supply decoupling is generous (0.1 uF ceramic adjacent to each VDD/VSS pair) and that the LCD segment bias generation (charge pump or external resistor ladder) is matched to the panel specification; using the internal charge pump with external reservoir capacitors is the most compact configuration.

PIC16LF1907-I/P - 8-bit MCU, 14KB Flash, LCD, nanoWatt XLP

The Microchip Technology PIC16LF1907-I/P is an 8-bit PIC microcontroller in the PIC® XLP™ 16F family, integrating 14KB of Flash program memory, 512 bytes of RAM, and an on-chip LCD driver in a 40-pin PDIP through-hole package. According to the verified distributor data, this device operates up to 20MHz instruction throughput from a 2.5V nominal supply (LF low-voltage variant) and is qualified to the industrial -40C to +85C temperature range (the 'I' suffix). Its ultra-low-power nanoWatt XLP technology is intended for battery- or energy-harvesting systems where sleep current is critical. An 8-bit microcontroller (MCU) is a self-contained computing element with an 8-bit data path, on-chip Flash for program storage, on-chip SRAM for data, and a rich set of peripherals such as timers, ADC, comparators, communications (UART, SPI, I2C), and increasingly integrated analog/RF functions. MCUs sit within the broader semiconductor taxonomy of embedded computing devices -> microcontrollers -> integrated circuits. Within Microchip's portfolio, the PIC16F190x family targets cost-sensitive applications that need LCD segment drivers and extreme low-power operation, bridging simple PIC10/12/16 baseline devices and higher-end PIC18/PIC24 devices. Key features of the PIC16LF1907-I/P include 14KB (8K x 14) Flash, 512 bytes RAM, an integrated LCD driver capable of driving segmented displays directly, 20MHz maximum clock, and nanoWatt XLP sleep modes that drop quiescent current into the sub-microamp range. The 40-pin PDIP package offers generous I/O for hand-wired prototypes, breadboarding, and legacy designs that prefer through-hole assembly over surface mount. The PIC16LF1907 architecture pairs a RISC-style 14-bit instruction set with a Harvard memory structure, allowing simultaneous instruction fetch and data access. The integrated LCD module can drive up to a defined number of segment and common pins (per datasheet), eliminating the need for an external LCD driver. nanoWatt XLP technology provides multiple low-power modes (Idle, Sleep, and deep Sleep variants) that allow the MCU to wake on interrupts, timer overflows, or peripheral events. Typical applications for the PIC16LF1907-I/P include battery-powered metering with LCD readouts, consumer appliances with segmented displays, handheld instrumentation, environmental sensors with LCD UI, and remote controls with low standby current. The 40-pin PDIP package is especially well suited to engineering prototypes and low-volume production runs that benefit from through-hole solderability and easy IC socket replacement. When designing with this part, ensure the supply rail stays within the LF family's voltage window, place a 0.1uF decoupling capacitor close to VDD, and route the ICSP/PGD/PGC lines for in-circuit programming and debugging. The MPLAB X IDE with XC8 compiler is the canonical toolchain; the PICkit 3/Snap or MPLAB ICD 3/4 programmers support the device family for both Flash programming and in-circuit debug.

It executes instructions at up to 20 MHz from an internal oscillator, supporting operating voltages of 1.8V to 3.6V (LF low-voltage variant) for battery-powered designs. A PIC microcontroller (Peripheral Interface Controller) is a family of 8-bit RISC microcontrollers from Microchip featuring Harvard architecture, separate program and data buses, and a compact instruction set optimized for embedded control. The PIC16F190X family sits in the mid-range PIC16 lineup (PIC10/12/16/18 hierarchy), offering a balance of low power, peripheral integration, and small footprint; the 'LF' prefix denotes the wide-voltage low-power variant, and 'XLP' (eXtreme Low Power) is Microchip's branded nanoWatt technology achieving quiescent currents in the microamp range for sleep states. Key features include 14KB Flash program memory, 512 bytes RAM, an integrated LCD driver supporting up to 116 segments, a 10-bit ADC with up to 17 channels, multiple communication peripherals (EUSART, MSSP I2C/SPI), and nanoWatt XLP sleep currents typically below 1 uA. The 'T' suffix denotes Tape & Reel packaging for high-volume assembly. Internally, the PIC16LF1907 uses an enhanced mid-range 8-bit core with a hardware multiplier, 16-level hardware stack, and configurable oscillator block supporting internal 16 MHz HFINTOSC, 31 kHz LFINTOSC, and external crystal modes. The integrated LCD driver includes charge pump and voltage regulator blocks enabling direct glass driving without external bias components. Typical applications include battery-powered consumer products with segment LCDs (thermostats, scales, remote controls), industrial sensor transmitters with LCD readouts, low-power IoT edge nodes, metering and instrumentation displays, and white-goods user interfaces. The XLP technology is specifically engineered to extend coin-cell battery life beyond five years in intermittent-duty applications. When designing with this device, budget I/O pins carefully - the 44-pin TQFP exposes 36 GPIO lines but several are multiplexed with the LCD segment outputs, requiring pin allocation trade-offs when both LCD and digital I/O are required.

The Microchip Technology PIC16LF19155-E/SP is an 8-bit RISC PIC16 microcontroller running up to 32MHz with 14KB (8K x 14) of Flash program memory, 1KB of SRAM, and 256 bytes of Data EEPROM, housed in a 28-pin SPDIP (Skinny Plastic DIP, 0.300 inch/7.62 mm) through-hole package. The '-LF' prefix indicates the wide-voltage 1.8V-3.6V core optimized for XLP (eXtreme Low Power) operation, with eXtreme Low-Power peripherals aimed at coin-cell and battery-powered designs. The '-E' suffix denotes the -40C to +125C extended operating temperature range, while the '/SP' package code is the 28-pin SPDIP. A PIC (Peripheral Interface Controller) microcontroller is a class of single-chip microcontrollers built around Harvard-architecture RISC cores with on-chip Flash, RAM, EEPROM, and mixed digital/analog peripherals; the PIC16 family is the mid-range tier of Microchip's 8-bit portfolio, positioned between PIC10/12/16 baseline and PIC18 enhanced cores, and is widely used in general-purpose and low-power embedded applications. PIC microcontrollers belong to the broader category of microcontrollers -> embedded processors -> semiconductor devices, and dominate the 8-bit MCU market alongside 8051 derivatives and AVR. Key features include a 12-bit ADC with computation (ADC2), two 5-bit DACs, two comparators, an 8-bit DAC, a Hardware Limit Timer (HLT), a Windowed Watchdog Timer (WWDT), CRC/SCAN memory integrity checking, and Core Independent Peripherals (CIPs) such as CWG, NCO, and PWM that can operate without CPU intervention. The device provides up to 24 GPIO pins, supports eXtreme Low-Power sleep currents in the sub-uA range with multiple low-power modes (DOZE, IDLE, SLEEP), and integrates an LCD driver (on LCD variants of the family) plus a charge pump for regulated LCD bias generation on the LCD-equipped siblings. The PIC16LF19155 architecture pairs a 14-bit instruction word with a Harvard bus, providing deterministic instruction timing and a streamlined peripheral set that allows complex functions to be implemented in hardware without CPU overhead. The XLP design supports battery voltages down to 1.8V and includes peripheral modules that retain state in sleep, allowing wake-on-event operation that minimizes total system energy. Typical applications include low-power IoT sensor nodes, battery-powered LCD user interfaces, home appliances, remote controls, security panels, energy-harvesting endpoints, and consumer handhelds where sub-uA sleep and integrated Core Independent Peripherals reduce BOM cost. The 28-pin SPDIP package also makes the part a drop-in for DIP-socketed legacy designs and breadboard prototyping. When designing with this part, ensure decoupling follows the Microchip PIC16LF19155 datasheet typical-application circuit (typically 0.1uF plus bulk 1-10uF on VDD), and use the MPLAB XC8 compiler with the latest PIC16F19155 device pack to access ADC2, HLT, and WWDT libraries. The Device ID and Configuration Words must be set per application; lock bits should be configured after firmware is finalized. Pay attention to the 1.8V minimum VDD at full speed - operation below 2.0V typically requires the lower 32 kHz LF oscillator or reduced FOSC.
