PIC16F1933-I/ML - 7KB Flash 28-QFN 8-Bit MCU | Microchip

The Microchip Technology PIC16F1933-I/ML is an 8-bit Flash-based CMOS microcontroller built on the PIC16 enhanced mid-range core, packaged in a 28-pin QFN (ML, 6x6 mm) with an exposed thermal pad. It integrates 7 KB of Flash program memory (4K x 14 words), 256 bytes of SRAM, and 256 bytes of EEPROM data memory. The device runs at instruction-cycle speeds up to 32 MHz (8 MIPS) from a 1.8 V to 5.5 V supply, making it a member of Microchip's nanoWatt XLP extreme-low-power family. What is a PIC16 microcontroller? The PIC16 family is a family of 8-bit RISC microcontrollers from Microchip Technology with a Harvard architecture, separate program and data buses, and a small instruction set optimized for deterministic execution in embedded control. The PIC16F1933 adds an integrated LCD driver (up to 96 segments), a 5-bit DAC, multiple enhanced capture/compare/PWM (ECCP) modules, and configurable logic cells (CLC) on top of the standard PIC16 peripherals. It sits inside the broader PIC mid-range taxonomy: PIC10/12/16/18 -> 8-bit MCU -> microcontroller -> embedded processing -> semiconductor IC. Key features include 11 channels of 10-bit ADC, two comparators, two 8-bit timers plus one 16-bit timer, hardware RTCC, an EUSART, MSSP (I2C/SPI), and an internal 16 MHz oscillator. XLP technology delivers typical sleep currents around 50 nA at 1.8 V, enabling battery-powered designs with multi-year lifetimes. The 28-QFN (6x6 mm) package supports compact board layouts and provides a low thermal-resistance path via the exposed pad. Typical applications include battery-powered consumer devices with LCD user interfaces, IoT sensor nodes, metering and instrumentation, medical monitors, and industrial HMI panels. The integrated LCD driver eliminates external segment-driver ICs, reducing both BOM cost and PCB area in user-interface-heavy designs. When designing with this part, observe the 1.8 V minimum VDD for Flash operation, place a 0.1 uF decoupling capacitor adjacent to each power pin, and connect the exposed pad to the ground plane for thermal dissipation and electrical reference. The CLC, ECCP, and 5-bit DAC peripherals are configured via MPLAB X IDE and MCC.

PIC16F1933-I/SO - 8-bit XLP MCU, 7KB Flash, 28-SOIC | Microchip
PIC16F1933-I/SO

PIC16F1933-I/SO - 8-bit XLP MCU, 7KB Flash, 28-SOIC | Microchip

The Microchip Technology PIC16F1933-I/SO is an 8-bit enhanced mid-range PIC16 flash microcontroller with 7 KB of program memory, 256 bytes of RAM, and 256 bytes of EEPROM, packaged in a 28-pin 300-mil SOIC (SO) outline. It operates from 1.8 V to 5.5 V across an industrial temperature range of -40 °C to +85 °C and executes instructions at a 200 ns cycle time from an internal 32 MHz oscillator. According to the manufacturer datasheet, the device integrates nanoWatt XLP extreme-low-power technology with active current below 6 µA/MIPS, sleep current in the nA range, and a dedicated LCD driver that can drive up to 4 commons × 28 segments without external bias resistors. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, timers, communication peripherals, and I/O onto one silicon die. Within Microchip's taxonomy, the PIC16F1933 sits inside the enhanced mid-range PIC16F193x/194x family, which itself falls under the broader 8-bit PIC microcontroller category, then under the microcontroller product line, then under Microcontrollers & Microprocessors, and finally under Integrated Circuits. This hierarchical position explains why the part is widely used as a drop-in upgrade for legacy PIC16F877A and PIC16F886 designs. Key features include an integrated LCD driver supporting static, 1/2, 1/3, and 1/4 multiplex displays, a 10-bit ADC with up to 17 channels, two Capture/Compare/PWM (CCP) modules, an Enhanced USART, MSSP for SPI and I²C, five 8-bit timers plus one 16-bit timer, and a charge time measurement unit (CTMU) for capacitive touch and basic temperature measurement. The CTMU, combined with mTouch firmware, lets engineers add touch-sensing buttons without an external controller IC. Architecturally, the device uses a Harvard RISC core with separate program and data buses, allowing instruction fetch and operand read on the same cycle. The XLP nanoWatt technology implements multiple idle, sleep, and doze modes with peripheral clock gating so that typical real-world current draw for a battery-driven LCD keypad application can stay below 5 µA average at 3 V. Typical applications include battery-powered LCD keypads for security and HVAC panels, low-cost industrial timers and counters with character LCDs, metering and sensor front-ends using the 10-bit ADC plus CTMU, consumer appliances such as rice cookers and washing-machine front panels, and portable medical devices like blood-pressure monitors. The wide 1.8 V-5.5 V range lets a single SKU cover both 3.3 V and 5 V designs. When laying out a board, route the VDD/VSS pairs with star topology and place the 100 nF decoupling capacitor within 3 mm of each power pin; on 28-pin SOIC designs, only one VDD/VSS pair exists, but the AVDD/AVSS analog supply still benefits from a 10 nF plus 100 nF pair near the ADC inputs. Do not leave the MCLR pin floating; tie it to VDD through a 10 kΩ resistor to ensure reliable reset behaviour.

The device includes up to 25 I/O pins, four 8-bit timers plus one 16-bit timer, and a Capture/Compare/PWM module suitable for motor and lighting control. Architecturally, the PIC16F1933 uses a RISC instruction set with 49 instructions, hardware stack, and a 14-bit instruction word. Its nanoWatt XLP technology enables sleep currents below 1 µA, making the device suited for battery-powered and energy-harvesting designs. The integrated LCD driver eliminates an external charge-pump or segment-driver ASIC in glass-display applications. Typical applications include industrial control panels with character LCDs, consumer white goods with user interfaces, low-power sensor nodes, HVAC thermostats, and battery-powered instruments. The wide voltage range and integrated peripherals allow designers to consolidate multiple discrete components into a single chip. When designing with the PIC16F1933, ensure that programming voltage and MCLR pin handling follow the datasheet's in-circuit serial programming procedure. Use a decoupling capacitor within 5mm of each VDD/VSS pair, and keep the 32kHz or high-frequency crystal traces short to minimise EMI.

PIC16F1933-I/SS

PIC16F1933-I/SS - 8-Bit 32MHz 7KB Flash XLP MCU | Microchip

The Microchip Technology PIC16F1933-I/SS is a nanoWatt XLP eXtreme Low-Power 8-bit PIC microcontroller built on a CMOS process with a 32 MHz internal oscillator and 7 KB (4K x 14) of self-programmable Flash program memory. Housed in a 28-pin SSOP package with 0.65 mm terminal pitch, it integrates 256 bytes of RAM, 256 bytes of EEPROM, and an integrated LCD driver, delivering high analog and digital integration in a small-footprint surface-mount form factor. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, non-volatile storage, and a rich set of peripherals (timers, ADC, communication interfaces, GPIO) into one IC. Within the broader semiconductor hierarchy, the PIC16F1933 belongs to the 8-bit microcontroller category, which sits inside the embedded controller family, itself a branch of microcontrollers and microprocessors in the integrated-circuit taxonomy. The 'XLP' designation places this part in Microchip's nanoWatt XLP low-power lineage, optimized for battery-operated and energy-harvesting designs. Key features of the PIC16F1933 include 25 digital I/O lines (some sources state 12 I/O pins depending on package option; the 28-pin SSOP exposes 25), 11 channels of 10-bit ADC, an integrated LCD driver capable of driving segment LCDs directly, multiple timers, an EUSART, MSSP (SPI/I2C), and a wide 1.8V-5.5V supply range (industrial variant) that allows direct Li-ion battery operation. The integrated LCD segment driver eliminates the need for an external charge-pump or driver IC, reducing BOM cost for metering and appliance front panels. Architecturally, the part uses the standard enhanced mid-range PIC16 core with a 14-bit instruction word and a hardware stack, plus the nanoWatt XLP sleep modes (deep sleep, idle, doze) that drop the active current to roughly 50 nA in deep sleep with RTCC and WDT running. The 32 MHz internal oscillator provides 8 MIPS performance, adequate for sensor sampling, user-interface handling, and low-speed communication tasks typical of metering, white goods, and consumer gadgets. Typical applications include water/gas/electricity metering with LCD readout, household appliances (washing machines, microwave ovens, induction cooktops), battery-powered sensor nodes, consumer electronics with segment LCD displays, and industrial control panels. The integrated LCD driver makes it particularly attractive for metering and appliance UI where a low BOM is essential. A secondary use case is replacing legacy PIC16F886 designs with a more capable pin-compatible upgrade that adds LCD support. When designing with this device, follow Microchip's recommended 100 nF bypass capacitor on VDD placed within 4 mm of the pin, and a 10 kΩ pull-up on MCLR if in-circuit serial programming is required. Avoid routing high-frequency switching traces adjacent to the LCD segment pins to minimize ghosting. Pin-compatible migration paths exist within the PIC16F193x family for design flexibility across memory sizes and packages.

Key features include 14-bit instruction width, an integrated LCD driver (up to 28 segments), a 10-bit ADC with up to 11 channels, multiple PWM modules, comparators and the nanoWatt XLP sleep mode that drops quiescent current to the sub-microamp range. The 28-SOIC (SO) industrial grade (-I) package and tape-and-reel (T) shipping format target production-friendly assembly. Typical applications include battery-powered consumer and home appliances with glass displays, e-metering, sensor conditioning front-ends, small appliances, white goods and any low-power embedded system that benefits from an on-chip LCD driver. The wide operating voltage range (1.8 V to 5.5 V) and the XLP idle/sleep modes make the device particularly well suited to energy-harvesting or primary-cell designs that must wake periodically to take a measurement and return to deep sleep. A common design pitfall is forgetting to switch the device to the internal LFINTOSC or to configure the System Clock Selector (SCS) before issuing a SLEEP instruction, which can leave the part drawing extra current through a still-running external oscillator. Always verify the CONFIG1 register clock source bits in MPLAB X before characterising sleep current.

It runs up to 32 MHz (8 MIPS) from a 2.5V to 5.5V supply, integrates an LCD driver with charge pump, and supports the nanoWatt XLP ultra-low-power family. An 8-bit microcontroller (MCU) is a small computing system on a single chip that contains a CPU, RAM, non-volatile program memory (Flash/ROM), and peripherals such as timers, ADC, communication ports, and GPIO. Within the broader taxonomy it sits under microcontroller -> embedded processor -> semiconductor.

Per Microchip datasheet 40001591D, the device includes 256B EEPROM with 1M erase/write cycles endurance and supports ICSP (In-Circuit Serial Programming) for field updates. Active current is typically below 2 mA at 8 MHz, and sleep current drops to roughly 50 nA with LCD charge pump disabled. Architecturally, the PIC16F1934 uses a 14-bit instruction word RISC core with a hardware multiplier, providing deterministic single-cycle instruction execution. The integrated LCD driver supports up to 96 segments in multiplexed mode (1/4 duty, 1/3 bias) using an internal charge pump that can operate down to 2.5V without external boost components, simplifying display-based designs. Typical applications include battery-powered thermostats and sensor nodes, low-cost consumer appliances with LCD readouts, irrigation controllers, and any ultra-low-power product that needs an on-chip segmented display. The wide 2.5V-5.5V operating range lets a single coin cell or 2xAA supply power both logic and the display. Design with the integrated LCD charge pump to eliminate external boost circuitry, but verify segment count vs your glass - more than 96 segments requires the larger PIC16F1936/1937/1938/1939 variants.

It integrates 7 KB of flash program memory (4K x 14 words), 256 bytes of SRAM, and 256 bytes of EEPROM, and runs at instruction-cycle speeds up to 32 MHz (8 MHz internal oscillator with 4x PLL) across a 1.8 V to 5.5 V supply range. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripheral interfaces on one die. The PIC16F1934 belongs to the PIC16 mid-range family in the broader microcontroller taxonomy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. Its nanoWatt XLP technology adds an extreme-low-power sub-mode that drops active current below typical mid-range parts, making the device relevant in battery-powered segments. Key differentiating features include a segmented LCD driver (up to 96 segments), a 12-bit ADC with computation (ADC2) that automates averaging, filtering, threshold comparison, and oversampling, an 8-bit DAC, two comparators, capture/compare/PWM modules, an EUSART, MSSP (SPI/I2C), and up to 36 digital I/O pins with individually controllable internal weak pull-ups. The instruction set is 35 single-word instructions, all single-cycle except branches, and the part is supported by the MPLAB X IDE, XC8 compiler, and PICkit programmer/debugger tool chain. Architecturally, the PIC16F1934 uses a Harvard RISC core with separate program and data buses, allowing instruction fetch and operand access in the same cycle. The 14-bit instruction word packs opcode and operand into one fetch, the 16-level hardware stack limits nested calls, and on-chip oscillator calibration (factory trimmed to ±1%) removes external crystals in many designs. Typical applications include low-power LCD user-interface panels (thermostats, meters, appliances), battery-powered sensor transmitters, e-paper / segment LCD consumer products, white-goods control boards, and industrial sensor nodes that benefit from the ADC2 hardware-averaging. The wide 1.8-5.5 V supply tolerance suits both 3.3 V and 5 V rails without level translation. When designing with this part, reserve one I/O for in-circuit serial programming (ICSP) and another for the MCLR reset; both can be released to user code via configuration bits, but only after debugging is finished. The LCD charge pump allows display operation below the LCD threshold voltage but draws extra current, so disable it for non-LCD designs.

Typical applications include low-power LCD-based consumer products such as thermostats, blood pressure monitors, metering displays, sensor readout panels, IoT edge nodes with small graphical displays, and industrial HMI panels. The combination of segmented LCD control, low sleep current, and ample I/O makes it ideal when a full graphical TFT controller would be overkill. When designing with the ML (QFN-44) variant, attention must be paid to the exposed center pad, which must be soldered to the PCB ground plane for thermal and electrical performance. Programming is supported through Microchip's MPLAB X IDE, XC8 compiler, and the PICkit or ICD debuggers, with a wide ecosystem of application notes and code examples available.

In an LCD meter, the MCU can acquire sensor data through its ADC, perform calculations, update the integrated LCD driver, and manage switches or alarm outputs. In a battery-powered monitor, XLP operating modes can reduce consumption during inactive periods while preserving fast execution when measurements are required. Designers should allocate decoupling close to the supply pins, route sensitive analog inputs away from switching and high-current traces, and confirm oscillator, reset, programming, and LCD segment connections against the manufacturer's pin-description table. Because the DIP package has generous spacing, prototype boards are straightforward, but production designs should account for its larger footprint compared with surface-mount packages. This page combines the manufacturer's device information with distributor specifications, application guidance, package considerations, and engineering-focused selection notes. It also distinguishes verified operating characteristics from parameters that require confirmation in the manufacturer datasheet, helping engineers plan firmware, PCB layout, and sourcing without relying on generic microcontroller assumptions.

Typical applications include battery-powered consumer products with LCD segments (thermostats, weighing scales, remote controls, electric toothbrushes), home appliances and white goods, sensor signal conditioning with mTouch capacitive touch buttons or sliders, low-end human-machine interface panels, and educational/hobbyist projects using PIC kit development tools. The combination of integrated LCD driver and XLP ultra-low-power is what differentiates this family from general-purpose PIC16 parts. When designing with this device, plan the in-circuit serial programming (ICSP) pins (typically ICSPCLK/ICSPDAT and MCLR/Vpp) so the part remains accessible on the PCB for firmware updates and debug. The integrated LCD charge pump can simplify designs by allowing low-voltage battery operation while still meeting Vlcd requirements for typical TN glass, but external resistor selection per the datasheet remains essential.

It operates from 1.8 V to 5.5 V (the industrial "I" temperature grade spans -40 C to +85 C) and runs up to 32 MHz instruction rate from an internal oscillator. What is an 8-bit PIC microcontroller? A PIC microcontroller (Programmable Interface Controller) is a Harvard-architecture RISC processor family from Microchip Technology that integrates CPU core, Flash program memory, RAM, EEPROM, peripherals (timers, ADC, PWM, communication modules, I/O), and in this case an LCD segment driver, onto a single die. The PIC16F193x family sits in the PIC16 mid-range tier between the PIC10/12/16 baseline family and PIC18/dsPIC33 enhanced families, offering low cost, low power, and a generous peripheral mix including a built-in LCD driver that eliminates an external driver chip in display applications. Key features include 25 digital I/O pins (shared with segment and analog functions), a 10-bit ADC with up to 14 channels, multiple PWM modules, an integrated LCD driver supporting up to 96 segments, two 8-bit timers plus one 16-bit timer, an enhanced USART, an MSSP module for SPI and I2C (master/slave), nanoWatt XLP sleep currents below 1 uA in selected modes, an integrated voltage reference, and a low-power BOR/LVD. Architecturally the device uses a RISC Harvard core with single-cycle instruction decode (except branches) and a 14-bit instruction word; the Flash program memory supports self-programmability via ICSP and runs directly from the internal 32 MHz oscillator with no external crystal required for most designs. The LCD driver uses an internal charge pump and dedicated segment/common pins shared with GPIO, allowing common-glass LCDs (up to 4 common, 24 segment lines) to be driven without external bias resistors. Typical applications include battery-powered metering (gas, water, electricity), handheld thermometers and consumer appliances with LCD readout, IoT sensor nodes and remote controls, white-goods and HVAC user-interface panels, and automotive interior modules (cluster/trim displays). Designers favor this family for cost-sensitive products that need an integrated segmented display without an additional driver IC. Design tip: route the exposed pad (EP) of the 44-QFN to a continuous ground copper pour with multiple thermal vias for both electrical reference and thermal dissipation. The internal charge-pump capacitors for the LCD driver need a 1 uF X7R on the LCDCAP pin, and the segment lines require appropriate bias on VDD for stable contrast across the operating temperature range.

This category sits within the broader microcontroller hierarchy (microcontroller -> 8-bit MCU -> PIC16 -> enhanced mid-range -> XLP nanoWatt), making it a strong fit for cost-sensitive, low-power, LCD-equipped appliances. Key differentiating features include the integrated LCD driver with charge pump and contrast control, core-independent peripherals such as the Configurable Logic Cell (CLC), Complementary Waveform Generator (CWG), and Numerically Controlled Oscillator (NCO), plus the eXtreme Low Power (XLP) sleep mode drawing under 50 nA. The 28-pin SPDIP footprint exposes 25 GPIO lines, of which many are multiplexed with ADC, comparator, SPI, I2C, and UART peripherals, giving designers flexible pin mapping for sensor and user-interface boards. Architecturally, the device uses a 14-bit instruction word with a hardware stack of 16 levels and 35 instructions, combined with a wide peripheral set including 5 CCP/ECCP modules, an enhanced USART, MSSP for SPI/I2C, and a 16-level deep hardware stack. The 10-bit ADC delivers up to 17 channels with acquisition time configurable in software. The integrated LCD controller supports static, 1/2, 1/3, and 1/4 multiplexed glass with internal charge pump, eliminating the need for an external LCD bias supply in most designs. Typical applications include battery-powered consumer appliances with LCD readouts (coffee machines, kitchen scales, thermostats), industrial sensor transmitters with display feedback, and low-power IoT edge nodes that wake periodically to read sensors and update a segment display. Designers also use this part in medical handheld meters and HVAC control panels where a single chip must drive a glass LCD, scan buttons, and run low-power wireless protocols. A key design consideration is brown-out voltage selection: the PIC16F1936-I/SP supports BOR and LPBOR down to 1.8 V, which is critical for 2-cell alkaline or single-cell Li coin battery stacks. Always reserve the ICSP/ICD pins (RB6/RB7) for in-circuit programming and debugging, even in production layouts.

PIC16F1936T-I/ML - 14KB Flash 8-Bit MCU 28-QFN | Microchip
PIC16F1936T-I/ML

PIC16F1936T-I/ML - 14KB Flash 8-Bit MCU 28-QFN | Microchip

The Microchip PIC16F1936T-I/ML is an 8-bit PIC microcontroller from the PIC® XLP™ 16F family with 14KB (8K x 14) of Flash program memory, 32 MHz CPU clock, and integrated LCD driver, packaged in a 28-pin QFN (6x6 mm). It operates from 1.8V to 5.5V and is qualified to the industrial -40C to +85C temperature range. The 'T' suffix indicates Tape & Reel packaging, 'I' denotes industrial temperature grade, and '/ML' denotes the QFN-28 (6x6) lead-free package. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash), data RAM, EEPROM, peripherals (timers, ADC, communication, I/O), and interrupt logic onto one die. The PIC16F core uses a modified Harvard RISC architecture with a 14-bit instruction word and a two-stage pipeline, optimized for deterministic response and low interrupt latency. The PIC16F1936 sits within the XLP (eXtreme Low Power) family, where nanoWatt technology enables sleep currents below 50 nA, supporting battery-powered applications that demand years of standby life. Key features include 512B RAM, 256B EEPROM, an on-chip LCD driver capable of driving up to 64 segments, a 5-channel 10-bit ADC, multiple timers (Timer0/1/2/6), EUSART, I2C, SPI, and up to 25 digital I/O pins. Internal 16 MHz and 32 kHz oscillators reduce external component count. The integrated LCD charge pump and on-chip voltage reference minimize external BOM for glass and chip-on-board displays. The PIC16F1936 architecture uses CMOS flash technology with 100,000 erase/write endurance on the program memory and 1,000,000-cycle EEPROM endurance. Enhanced peripherals include mTouch capacitive sensing, an SR-latch, PWM modules, and a configurable logic cell. Together they provide flexibility for mixed-signal front-ends in a single MCU. Typical applications include battery-powered consumer devices with segment LCDs (thermostats, blood pressure monitors, water/gas meters), home appliances with user interfaces, industrial control panels, and remote sensor nodes. The XLP sleep current is critical for metering and IoT edge nodes powered by coin-cell or 2x AA cells. Design consideration: route the QFN-28 (6x6 mm) thermal/exposed pad (EP) to a continuous ground copper pour to dissipate up to ~800 mW and to meet the -40C to +85C industrial range under sealed-enclosure conditions. Enable the internal oscillator to save two external crystals and reduce BOM.

PIC16F1936T-I/MV

PIC16F1936T-I/MV - 8-bit 32MHz XLP MCU 14KB Flash 28-UQFN

The Microchip PIC16F1936T-I/MV is an 8-bit PIC® XLP™ flash microcontroller running at up to 32 MHz with 14 KB (8K × 14 words) of program Flash memory and a 28-pin UQFN (4 × 4 mm) exposed-pad package. It integrates 256 bytes of EEPROM, 512 bytes of RAM, a 10-bit ADC with up to 17 channels, and the nanoWatt XLP™ ultra-low-power technology that delivers typical sleep currents below 50 nA. An 8-bit microcontroller (MCU) is a compact, single-chip processor with an 8-bit data bus, typically integrating CPU, Flash program memory, SRAM data memory, EEPROM, timers, ADC, comparators, and serial peripherals into one package. Within the broader taxonomy, an MCU belongs to microcontrollers → integrated circuits (ICs) → semiconductors. The "PIC16" prefix designates Microchip's mid-range enhanced 8-bit core family, widely used in cost-sensitive and battery-powered embedded designs. Key features include an integrated LCD driver supporting up to 96 segments, three timers (Timer0/Timer1/Timer2), two comparators, a 5-bit DAC, EUSART, MSSP (I²C/SPI), 25 digital I/O pins, and 11 capacitive-touch channels via the mTouch™ peripheral. The nanoWatt XLP™ technology enables extended battery life across the 2.3 V to 5.5 V operating range. The UQFN-28 (MV) package has an exposed thermal pad, lowering θJA versus standard QFN and improving continuous high-current operation. Architecturally, the device uses the PIC16 enhanced mid-range core with a single-cycle instruction execution model (except branches) and a 16-level hardware stack. This RISC-style architecture simplifies deterministic timing analysis and code generation, while on-chip peripherals are mapped to linear memory to keep C-compiler output efficient. Typical applications include battery-powered IoT sensor nodes, low-power LCD-display consumer products, capacitive-touch user interfaces, household appliances, and industrial control panels. The wide 2.3 V to 5.5 V supply range makes it drop-in compatible with 2 × AA, 2 × AAA, single-cell Li-ion, and 5 V regulated rails. Designers should reserve the exposed pad for thermal relief and provide 0.1 µF decoupling on VDD/VSS pairs within 2 mm of the pins. For low-power battery designs, follow Microchip application note AN1267 on nanoWatt XLP™ sleep-current optimization. The PIC16F1936T-I/MV uses the T suffix to indicate tape-and-reel packaging.

PIC16F1937-E/ML - 8-Bit XLP MCU, 32MHz, 14KB Flash, 44-QFN | Microchip
PIC16F1937-E/ML

PIC16F1937-E/ML - 8-Bit XLP MCU, 32MHz, 14KB Flash, 44-QFN | Microchip

The Microchip PIC16F1937-E/ML is an 8-bit PIC microcontroller built on the enhanced mid-range PIC16 core with nanoWatt XLP (eXtreme Low Power) technology, delivering up to 32 MHz performance in a 44-pin QFN (8x8 mm) package. It integrates 14 KB Flash program memory (8K x 14 words), 512 bytes of SRAM, 256 bytes of EEPROM, an integrated LCD driver, and up to 36 I/O pins in a single low-power device. A microcontroller (MCU) is a single-chip computer containing a CPU, memory (Flash/EEPROM/RAM), and programmable peripherals, and it is the most widely deployed IC category in embedded systems. The 8-bit segment targets cost-sensitive, deterministic control tasks such as user interfaces, sensor readouts, and battery-powered appliances where ultra-low standby current matters more than throughput. The PIC16F1937 belongs to Microchip's PIC16 XLP family, which extends battery life into the multi-year range via sleep currents below 1 uA and active run currents measured in tens of microamperes per MHz. Key features include 32 MHz operation from a 1.8 V to 5.5 V supply, an integrated 10-bit ADC with up to 14 channels, multiple capture/compare/PWM modules, an enhanced USART, two MSSP (SPI/I2C) modules, and on-chip LCD driver support for up to 96 segments. The device also offers internal 16 MHz and 31 kHz oscillators, a configurable 16-level watchdog timer, and an enhanced 8-bit timer block. ICSP (In-Circuit Serial Programming) and ICD (In-Circuit Debug) support shrink development cycle time. Architecturally the PIC16F1937 uses a Harvard RISC design with a 14-bit wide instruction word and a hardware multiply, giving deterministic single-cycle execution for most instructions and predictable interrupt latency. nanoWatt XLP adds core-independent peripherals, a low-power Timer1 gate, and ultra-low-power wake sources, which let the CPU stay asleep while capacitive touch sensing or LCD refresh continues in hardware. The 14 KB Flash holds roughly 8K single-word instructions, suitable for protocol stacks plus application logic in mixed-signal front-end designs. Typical applications include consumer appliances with LCD front panels (washing machines, microwave ovens, thermostats), battery-powered sensor nodes with segmented displays, metering (energy, water, gas) with LCD readout, and industrial human-machine interface (HMI) terminals. It also fits USB-key peripherals, remote controls, and any cost-constrained design that benefits from on-chip LCD drive and nanoWatt XLP sleep currents below 1 uA. When designing with this MCU, reserve two PCB layers for clean VDD/AVDD decoupling with a 100 nF ceramic cap within 5 mm of each supply pin. If the internal ADC is used, tie VREF+ to a separate filtered rail to keep digital switching noise out of measurement. Use the LCDF<x> pins carefully - segment bias resistors and charge-pump capacitors must follow the LCD driver app note for stable contrast across temperature. This page synthesizes drop-in same-package PIC16 alternatives, distributor pricing snapshots, application circuits, and design guidance that go beyond a single device datasheet page, giving engineers a single decision point for the 44-QFN pin-out.
