PIC16LF1933T-I/MV Overview
What is an 8-bit microcontroller? An 8-bit microcontroller (MCU) is a single-chip computer that processes data in 8-bit words and integrates a CPU, program memory (Flash), data memory (RAM), non-volatile storage (EEPROM), and a configurable set of peripherals such as timers, communication interfaces, and ADCs. Within the Microchip hierarchy, the PIC16F/LF family is the enhanced mid-range tier: PIC microcontroller → 8-bit PIC MCU → PIC16F enhanced mid-range → PIC16LF low-voltage XLP sub-family.
Key features of the PIC16LF1933T-I/MV include 60 LCD segment drive support, integrated mTouch capacitive sensing, integrated temperature indicator, MI2C and SPI, EUSART with auto-baud detection, three ECCP and two CCP enhanced capture compare PWM modules, and comparators with selectable references. The device is available in industrial temperature grade (-40C to +85C) suitable for harsh embedded environments.
The PIC16LF1933 utilizes a Harvard architecture with separate 14-bit program and 8-bit data paths, allowing simultaneous instruction fetch and data access. The XLP nanoWatt technology enables standby currents in the microamp range and sleep currents as low as 20 nA typical, making the part well-suited to battery-powered applications like remote sensors, wearables, and metering. The integrated LCD driver eliminates the need for external segment drivers in HMI applications.
Typical applications include battery-powered sensor nodes, consumer HMI with glass-mounted LCD panels, low-cost user interfaces for home appliances, IoT edge nodes, and portable medical devices. Designers choose this part when they need a tiny-footprint MCU that combines a display interface and ultra-low standby power without a complex RTOS or high pin count.
When designing with the PIC16LF1933T-I/MV, ensure the exposed thermal pad is soldered to a sufficient copper pour to meet the UQFN-28 thermal resistance, and verify the chosen debugger/programmer is configured for the device ID. The internal 32MHz oscillator is factory-trimmed but small frequency errors are normal across voltage and temperature.

Typical Applications
PIC16LF1933T-I/MV is suitable for 7 applications: Battery-Powered Sensor Node, Thermostat and HVAC Controller, Portable Blood Pressure Monitor, Industrial Process Indicator, Smart Home Sensor Hub, Consumer Appliance HMI, Automotive Accessory Display.
Battery-Powered Sensor Node
The PIC16LF1933T-I/MV is a strong fit for battery-powered sensor nodes due to its nanoWatt XLP technology achieving sleep currents in the microamp range and an operating voltage down to 1.8V from two AA cells. The 32MHz internal oscillator and 11-channel 10-bit ADC support direct interfacing to thermistor, optical, and humidity sensors. The 7KB Flash accommodates over-the-air firmware update routines and sensor-fusion algorithms. The integrated temperature indicator simplifies cold-chain and HVAC deployments where ambient compensation is needed without an external sensor.
Recommended
Thermostat and HVAC Controller
The PIC16LF1933T-I/MV drives up to 60 LCD segments, ideal for thermostat front panels showing set-point, ambient temperature, and mode status without an external display driver. The integrated mTouch capacitive sensing module supports touch buttons or sliders on glass overlays, eliminating mechanical switches. Three ECCP and two CCP PWM outputs can directly drive TRIAC-based heater/cooler control circuits. The enhanced mid-range core executes proportional-integral control loops comfortably while leaving headroom for wireless stack stubs.
Recommended
Portable Blood Pressure Monitor
The PIC16LF1933T-I/MV suits portable medical devices such as blood pressure monitors where its integrated LCD driver can render systolic/diastolic/pulse readouts on a custom segmented display. The 1.8V minimum supply allows direct operation from two AAA batteries, and XLP sleep modes keep standby current below 5 microamps for multi-year shelf life. The integrated temperature indicator and 10-bit ADC measure cuff pressure via a pressure transducer and apply software-based oscillometric analysis within the 7KB Flash budget.
Recommended
Industrial Process Indicator
The PIC16LF1933T-I/MV serves as a 4-20mA loop-powered or battery-backed process indicator in industrial settings, displaying flow rate, level, or pressure on a segmented LCD. Its industrial -40C to +85C temperature grade supports outdoor panel installations. The EUSART with auto-baud detection interfaces to sensors or PLC backplanes, while the comparators with selectable references implement simple alarm thresholds without external circuitry. Up to 11 ADC channels monitor multiple process variables simultaneously.
Recommended
Smart Home Sensor Hub
The PIC16LF1933T-I/MV acts as an edge node in a smart-home wireless sensor hub where its low sleep current preserves battery life across thousands of mesh network transmissions. The mTouch sensing peripheral enables touch-based user inputs on decorative panels, while the EUSART/SPI can drive sub-GHz transceivers like the MRF24J40 or Bluetooth LE modules. The integrated LCD shows local status (battery, RSSI, sensor value) without requiring the network host to wake.
Recommended
Consumer Appliance HMI
The PIC16LF1933T-I/MV drives the user interface of consumer appliances such as coffee makers, microwaves, and washing machines, where its 60-segment LCD plus mTouch capacitive buttons replace traditional mechanical switches. The ECCP/CCP modules control buzzers, relays, and motor-direction logic, while the 1.8V to 5.5V range supports direct connection to rectified mains-derived 5V or 3.3V rails. Industrial temperature grade ensures reliability in kitchen or laundry environments.
Recommended
Automotive Accessory Display
Although not AEC-Q100 qualified, the PIC16LF1933T-I/MV can power aftermarket automotive accessories such as tire-pressure displays or voltage monitors where its integrated segmented LCD shows numeric values without a TFT backlight. The PIC16LF1933T-I/MV operates reliably across -40C to +85C and tolerates the 8V to 16V vehicle supply through an external LDO. Its low 1.8V minimum allows efficient operation when the accessory enters sleep mode during vehicle ignition-off.

Key Differentiators
- Highest Flash density in the 28-pin UQFN XLP family tier (vs PIC16LF1934-I/MV)
- Integrated 60-segment LCD driver eliminates external driver IC (vs PIC16LF1826-I/MV)
- Tape-and-reel packaging for high-volume SMT assembly (vs PIC16LF1933-I/MV)
- Lower cost than higher-memory same-family variants (vs PIC16LF1938-I/MV)
Design Notes
Estimated: The 28-UQFN (MV) package uses an exposed thermal pad that must be soldered to a ground copper pour of at least 1 square inch for stable thermal performance. Without the pad soldered, junction-to-ambient thermal resistance (theta_JA) degrades substantially and the MCU may throttle or misbehave above ~70C ambient at high CPU activity. Always include thermal vias under the exposed pad in the PCB layout.
The PIC16LF1933T-I/MV's nanoWatt XLP mode achieves standby currents in the microamp range with proper configuration. Place the device in SLEEP mode whenever possible, gate peripheral clocks via the PMD (Peripheral Module Disable) registers, and use the internal 31kHz LFINTOSC for timekeeping to retain the lowest sleep current. Per the datasheet, watchdog timer enable adds approximately 1uA; disable if not required.
For the 28-UQFN (MV) package, place decoupling capacitors as close to the VDD pins as possible: a 100nF ceramic on each VDD pair plus a single 10uF tantalum or ceramic bulk capacitor near the package. Keep analog traces (ADC, comparator) away from switching traces and provide a clean analog ground island. The LCD segment pins should be routed with minimal crossover to avoid coupling noise into the segment drive waveforms.
Do not confuse the 'LF' low-voltage variant with the standard 'F' variant: the 'LF' requires VDD above 1.8V, and configuring clock modes for the wrong voltage range will cause oscillator failure. Watch out for the 'T' suffix - it indicates tape-and-reel packaging, not a different die. Verify device ID via ICSP before programming to avoid programming the wrong PIC16 variant.
Compliance Information
RoHS compliant per Microchip product page. Not AEC-Q100 qualified - this is an industrial-grade part (-40C to +85C). For AEC-Q100 automotive designs, Microchip offers separate PIC16F/LF variants in the automotive-grade 'EP' or 'VAO' suffix.
