PIC16LF1933-E/MV Overview
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path that integrates a CPU core, program memory, RAM, peripherals and I/O on a single die. The PIC16 family uses Microchip's enhanced mid-range RISC core with 49 instructions and a 16-level hardware stack, positioning this part as a mid-complexity microcontroller within the broader hierarchy: microcontroller -> embedded processor -> semiconductor IC. The "LF" prefix denotes the low-voltage F-process variant optimized for ultra-low static and dynamic power.
Key features include a 32 MHz internal oscillator, up to 60 LCD segment drive support, an integrated mTouch capacitive sensing module, an on-chip temperature indicator and three ECCP plus two CCP PWM channels. Communication peripherals cover MI2C, SPI and an EUSART with auto-baud detect. The 14-channel 10-bit ADC with voltage reference supports sensor and analog signal acquisition.
The architecture combines the enhanced mid-range core with self-read/write flash, configurable logic cells (CLC) and a peripheral pin select (PPS) matrix that maps digital peripherals to a wide choice of I/O pins. The nanoWatt XLP sleep current of typically < 50 nA makes the part suited to applications that spend most of their life in standby.
Typical applications include low-power consumer LCD products, battery-powered instrumentation, capacitive-touch human interfaces, sensor nodes with LCD readout, and industrial control panels. Its combination of LCD driver, mTouch and low quiescent current removes several external components and a dedicated touch controller.
When designing with the device, plan current budget around the nanoWatt XLP sleep modes and verify that the chosen regulator can sustain the LCD charge-pump transient load. Route the analog VDD/VSS pair separately from the digital supply to preserve ADC accuracy.

Typical Applications
PIC16LF1933-E/MV is suitable for 6 applications: Battery-Powered LCD Consumer Products, Capacitive-Touch User Interfaces, Industrial Sensor Nodes with LCD Readout, Portable Medical Monitoring Devices, Motor Control and Small Fan Drives, Automotive Dashboard Auxiliary LCDs.
Battery-Powered LCD Consumer Products
The PIC16LF1933-E/MV is a strong fit for battery-powered LCD consumer products because its nanoWatt XLP technology delivers sleep currents typically below 50 nA while the integrated segment LCD driver can drive up to 60 segments directly from the device. With 7 KB of flash, 256 B of RAM and 256 B of EEPROM, there is sufficient headroom for menu state, RTC tick handlers and user preference storage in products such as digital thermometers, kitchen scales and small home appliances. The 1.8 V to 3.6 V Vdd range aligns with two fresh alkaline or a single Li-ion cell, eliminating boost converters. The on-chip mTouch peripheral adds capacitive buttons without an external controller. Designers gain PCB area and BOM savings by combining MCU, LCD bias, charge pump and touch sensing in one 4x4 mm UQFN-28 part.

Capacitive-Touch User Interfaces
The PIC16LF1933-E/MV's on-chip mTouch peripheral allows direct connection of capacitive sense electrodes, replacing an external touch controller and reducing both BOM cost and PCB area. Combined with the 60-segment LCD driver, a single chip can drive both the segmented glass display and the touch keypad in products like induction cooktops, washing-machine control panels and HVAC wall thermostats. The 10-bit ADC with up to 14 channels can simultaneously read analog front-panel signals such as NTC temperature sensors or potentiometers. The peripheral pin select (PPS) matrix reassigns digital functions to free I/O for the touch electrodes, simplifying PCB layout in dense control panels.
Recommended
Industrial Sensor Nodes with LCD Readout
Industrial sensor nodes with local LCD readout benefit from the PIC16LF1933-E/MV's combination of XLP sleep currents, integrated LCD driver and extended -40 °C to +125 °C temperature grade. The 10-bit ADC with 14 input channels can scan multiple analog sensors, while MI2C/SPI/EUSART peripherals link to digital sensors, FRAM memories or RS-485 transceivers. The on-chip temperature indicator adds a free internal die-temperature monitor that can warn of over-temperature conditions without an external sensor. The 32 MHz HF oscillator and 31 kHz LF oscillator allow the MCU to switch rapidly between active acquisition and deep-sleep idle states, extending battery life in remote, maintenance-free installations such as wireless HVAC transmitters or factory-floor data loggers.
Recommended
Portable Medical Monitoring Devices
Portable medical monitoring devices such as blood-pressure cuffs, glucose meters and pulse oximeters require low power, accurate analog front ends and clear LCD readouts, all of which the PIC16LF1933-E/MV provides on a single die. The 10-bit ADC can digitize pressure or optical sensor outputs, while the integrated LCD segment driver displays measurements directly without an external display controller. The LF process keeps operating current low, supporting the long battery life required by home medical devices. The mTouch peripheral supports sealed capacitive buttons that meet the IP-rated enclosure requirements typical of medical products. Combined with the extended -40 °C to +125 °C temperature grade, the device is suitable for both home and clinical environments.

Motor Control and Small Fan Drives
The PIC16LF1933-E/MV's three ECCP and two CCP PWM modules with programmable dead-band control, auto-shutdown and complementary output modes are well suited to driving small DC brushless motors and fan blowers in HVAC, white-goods or computing applications. The 10-bit ADC supports back-EMF sensing for sensorless BLDC commutation algorithms, while the EUSART with auto-baud handles command interfaces to a host controller. The integrated temperature indicator provides a free thermal-protection input, allowing firmware to throttle or shut down the drive on over-temperature conditions. The 32 MHz internal oscillator provides deterministic timing for commutation loops without an external crystal, reducing BOM cost in cost-sensitive motor designs.
Recommended
Automotive Dashboard Auxiliary LCDs
The PIC16LF1933-E/MV's -40 °C to +125 °C extended temperature grade and integrated LCD segment driver make it well suited to non-safety auxiliary displays in automotive dashboards such as climate-control panels, audio head-unit sub-displays and rear-seat HVAC indicators. The MI2C and SPI peripherals connect to the central body or infotainment network, while the mTouch peripheral supports backlit capacitive buttons. While this part is not AEC-Q100 qualified, designers can pair it with an external CAN-FD transceiver for body-network integration in non-safety domains. The nanoWatt XLP sleep current supports key-off parasitic draw budgets below 100 µA typical.

Key Differentiators
- Highest LCD segment drive in UQFN-28 footprint (vs PIC16LF1903-E/MV)
- Extended temperature range for non-AEC automotive use (vs PIC16LF1933-I/MV)
- 1.8 V-3.6 V low-voltage optimization for two-cell battery designs (vs PIC16F1933-E/MV)
- 5 PWM channels with 3 ECCP blocks for motor control (vs PIC16LF1826-E/MV)
Design Notes
Estimated: the nanoWatt XLP sleep current is typically below 50 nA in deep sleep with RTC off. To maximize battery life in two-cell alkaline designs (Vdd < 2.0 V toward end-of-life), verify regulator dropout before MCU brown-out at 1.8 V nominal. The integrated LCD charge-pump draws short periodic bursts of several hundred microamps; size decoupling accordingly.
The "/MV" package is a 4x4 mm UQFN with an exposed die pad that must be soldered to a ground pad for thermal and electrical performance. Failed solder joints under the pad are a common factory defect source; follow Microchip's UQFN PCB layout guidelines including multiple thermal vias and a 0.3 mm-0.4 mm stencil aperture for the center pad.
Route the analog VDD/VSS pair (AVDD/AVSS, when present on the larger pin-count family members) separately from the digital supply to preserve 10-bit ADC accuracy; on this 28-pin UQFN both rails share VDD/VSS, so use a ferrite bead or star-ground layout. Place the 0.1 uF VDD bypass within 3 mm of the VDD pin and a 10 uF bulk capacitor on the same supply rail.
PPS (Peripheral Pin Select) lets you remap digital peripherals to almost any I/O, but each input-only or output-only mapping is limited and not all pin combinations are legal. Validate the PPS assignment in the MPLAB X IDE Configuration Bits tool to avoid accidental remap conflicts at startup.
Compliance Information
RoHS and REACH compliance per Microchip product page. Not AEC-Q100 qualified - this part is targeted at consumer, industrial and non-safety automotive sub-display applications. Lead-free reflow profile compatible with JEDEC J-STD-020.
