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.

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.

The PIC16F1933 belongs to the enhanced mid-range family, sits inside the broader power-management IC hierarchy, and is part of the PIC16F1xxx series that adds LCD driver support and nanoWatt XLP extreme-low-power technology. 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. The PIC16F1934 belongs to the mid-range PIC16 family, optimized for ultra-low-power XLP applications such as battery-powered instruments, consumer white goods, and human-machine interfaces that need an integrated LCD glass driver. Key features include 12 I/O pins shared with LCD segments, an internal 32 MHz oscillator, 10-bit ADC with capacitive touch support (mTouch), multiple PWM/ECCP modules, and hardware Master Synchronous Serial Port (MSSP) for SPI/I2C. 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.

PIC16F1934-E/P - 7KB Flash 8-bit MCU, 32MHz, LCD, XLP | Microchip

The Microchip Technology PIC16F1934-E/P is an 8-bit CMOS flash microcontroller belonging to the PIC16F193X/PIC16LF193X family with nanoWatt XLP extreme-low-power technology, housed in a 40-pin PDIP (P) through-hole package. 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.

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.

The nanoWatt XLP technology delivers typical sleep currents below 1 µA with full RAM retention and watchdog timer operation, making the device suitable for applications that spend most of their time in standby. The PIC16F1936 implements a modified Harvard architecture with separate program and data buses, an 8-level hardware stack, and an instruction set optimized for C code generation through the XC8 compiler. The integrated mTouch capacitive-sensing peripheral and CTMU (Charge Time Measurement Unit) add touch-button and proximity-sensing capability without external components. Typical applications include battery-powered consumer devices with LCD displays, home automation sensor nodes, automotive instrument clusters (PIC16F1936-I/MV industrial variant), medical glucose meters and portable monitors, IoT edge sensors with local display feedback, and low-cost white-goods user interfaces. The -E suffix denotes the Extended temperature grade (-40°C to +125°C), while /MV indicates the 28-pin UQFN-EP package. When designing with this device, allocate one I/O pin per LCD segment above the integrated 4 commons x 24 segments baseline and verify charge-pump capacitor selection against the on-glass panel capacitance. Programming via ICSP requires RB6/ICCK and RB7/ICCDAT to remain accessible; avoid reassigning them to high-load outputs without a test-point footprint.

PIC16F1936-E/SO

PIC16F1936-E/SO - 8-Bit 32MHz 14KB Flash MCU | Microchip

The Microchip Technology PIC16F1936-E/SO is an 8-bit CMOS microcontroller belonging to the PIC16F193x/194x family, featuring 14KB of Flash program memory, 512 bytes of RAM, and 256 bytes of EEPROM, housed in a 28-pin SOIC package. It operates at up to 32 MHz clock speed from a 2.3V to 5.5V supply, integrating an LCD driver, a 10-bit ADC, and nanoWatt XLP extreme-low-power technology for battery-friendly designs. A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, working RAM, and a rich set of peripheral interfaces. Within the broader semiconductor taxonomy, an 8-bit MCU sits below 16-bit and 32-bit MCUs in arithmetic width and code density, but excels in deterministic interrupt response, low cost, and very low quiescent draw for always-on edge nodes. The PIC16F1936 is part of Microchip's enhanced mid-range 8-bit core family, with the XLP nanoWatt lineage adding sleep currents down to the nanoampere range - well suited to battery-powered metering, sensor nodes, and human-machine interface panels that must last years on a single cell. Key features include 25 general-purpose I/O pins, a 10-bit ADC with up to 14 channels, an integrated LCD driver supporting up to 96 segments, two comparators, a 5-bit DAC, EUSART, SPI, and I2C communication peripherals. The on-chip mTouch capacitive-sensing module and the nanoWatt XLP power management modes (Idle, Doze, Sleep, and alternate-run) allow the device to drop below 50 nA in real-world deep-sleep scenarios. Architecturally, the PIC16F1936 uses Microchip's enhanced mid-range 8-bit RISC core with a hardware 8x8 multiplier, a single-cycle instruction execution at 32 MHz (125 ns instruction cycle), and a 16-level hardware stack. The integrated LCD driver includes a charge pump and contrast control, allowing direct connection to multiplexed glass displays without an external driver IC. A 32 kHz internal LF oscillator and a 32 MHz internal HF oscillator minimize external components in space-constrained designs. Typical applications include battery-powered IoT sensor nodes, consumer remote controls, thermostats, white-goods HMI panels, metering front-ends, and any cost-sensitive embedded design needing an integrated LCD segment driver. The wide 2.3V-5.5V operating range also suits USB-powered and 3.3V-rail products. When designing with this part, pay close attention to the ICD/ICSP pin assignments (RB6/ICLK, RB7/ICDAT) to keep them accessible for in-circuit debug, and reserve the correct configuration bits for oscillator source, watchdog, and code protection before code generation. The -E temperature grade extends to +125C, making the part suitable for under-hood and industrial cabinet environments.

PIC16F1936-E/SP - 8-bit 32MHz MCU 14KB Flash LCD XLP | Microchip

The Microchip Technology PIC16F1936-E/SP is an 8-bit CMOS flash microcontroller in the PIC16F193x family featuring nanoWatt XLP (eXtreme Low Power) technology and an integrated LCD driver. The device delivers 32 MHz (8 MIPS) CPU performance from a 14 KB (8K x 14 words) flash program memory, 512 bytes of SRAM, and 256 bytes of EEPROM data memory, all housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. The -E suffix denotes the Extended industrial temperature range of -40 C to +125 C, while the /SP suffix indicates SPDIP-28 packaging supplied in tube. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (ROM/flash), working memory (RAM), non-volatile data memory (EEPROM), and programmable peripherals. The PIC16F1936 belongs to the enhanced mid-range PIC16 family using a RISC Harvard architecture, in the hierarchy: PIC16F1936 -> PIC16 enhanced mid-range -> PIC16 family -> 8-bit PIC microcontrollers -> microcontrollers -> embedded processors -> semiconductors. Its integrated LCD driver, multiple communication peripherals, and 10-bit ADC make it a complete system-on-chip for human-interface and battery-powered designs. Key features include 25 general-purpose I/O pins, an integrated 10-bit ADC with up to 11 channels, two comparators with selectable references, an mTouch capacitive sensing module, an EUSART, MSSP (SPI/I2C), and a charge time measurement unit (CTMU). The nanoWatt XLP technology delivers typical sleep currents down to 20 nA with the Real-Time Clock operating, enabling multi-year battery life in metering, sensor, and remote-control applications. The architecture implements a single-cycle instruction pipeline operating at 200 ns per instruction, with hardware interrupt context save and a 31 kHz internal oscillator option. The integrated LCD driver supports up to 184 segments (pin-dependent) with variable contrast control and multiple drive modes, eliminating the need for an external LCD controller. Typical applications include low-power LCD-based consumer products, battery-operated sensor nodes, home-automation keypads, instrumentation displays, industrial HMI panels, and metering equipment. The /SP SPDIP-28 package is favored for prototype and through-hole industrial designs where socketed or hand-replaceable MCUs simplify rework. When designing with this part, evaluate the supply voltage range (1.8 V to 5.5 V) against your battery chemistry and use the nanoWatt sleep modes aggressively for battery applications. Always configure the unused I/O pins as outputs low to minimize quiescent current, and follow Microchip's emulated EEPROM guidance to extend flash endurance when using EEPROM emulation libraries.
