PIC16F1936-E/SP Overview
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.

Typical Applications
PIC16F1936-E/SP is suitable for 7 applications: Battery-Powered LCD Sensor Nodes, Industrial HMI Keypad Panels, Consumer Remote Controls and Appliance Interfaces, Electronic Metering and Utility Displays, Medical Monitoring Device Front Panels, Automotive Dashboard Sub-Displays, IoT Smart Home Sensor Hubs.
Battery-Powered LCD Sensor Nodes
The PIC16F1936-E/SP fits battery-powered LCD sensor nodes because its nanoWatt XLP sleep current of approximately 20 nA with RTCC and active current of 1.8 mA at 4 MHz support multi-year coin-cell operation. The integrated LCD driver eliminates an external display controller, while the 10-bit ADC with 11 channels handles multiple sensor inputs directly. Engineers typically run the device from 2xAA or 3V coin cells at 1.8 V minimum, wake on interrupt, take readings, update LCD, and return to sleep for 99% of the duty cycle.
Recommended
Industrial HMI Keypad Panels
The PIC16F1936-E/SP suits industrial HMI keypad panels because the integrated LCD driver supports up to 96 segments in SPDIP-28 for displaying multiple process variables, while the mTouch CTMU implements capacitive touch keys without external sense ICs. The Extended -40 C to +125 C temperature range supports factory-floor installations. Two comparators and selectable internal references enable sensor threshold detection directly, with EUSART and I2C for backhaul communication to a main controller.
Recommended
Consumer Remote Controls and Appliance Interfaces
The PIC16F1936-E/SP suits consumer remote controls and appliance interfaces due to its nanoWatt XLP sleep current below 100 nA without RTCC, supporting years of standby life on 2xAAA cells. The LCD driver provides direct segment display for time, channel, or temperature feedback. Hardware PWM channels drive IR LEDs, the mTouch CTMU replaces mechanical buttons with capacitive touch, and the integrated 10-bit ADC reads battery voltage and ambient conditions. Programming in C with MPLAB X IDE and XC8 compiler keeps BOM cost minimal.
Recommended
Electronic Metering and Utility Displays
The PIC16F1936-E/SP serves electronic metering and utility displays because its integrated LCD driver, 32 MHz CPU, and EUSART/MSSP peripherals support metering front-end communications and LCD readout in a single chip. The 14 KB flash holds metering firmware, calibration tables, and LCD segment maps. The Extended -40 C to +125 C temperature grade meets outdoor and basement installations. Low-power modes preserve battery backup during line-power outages while keeping displayed values accurate.
Recommended
Medical Monitoring Device Front Panels
The PIC16F1936-E/SP fits medical monitoring device front panels because the integrated LCD driver displays multiple vital signs, the mTouch CTMU provides capacitive touch for sealed user interfaces, and the Extended temperature range supports clinical and home environments. The 14 KB flash holds IEC 62304-compliant firmware modules. Hardware CRC and WDT support safety-critical designs. The 1.8 V minimum supply accommodates battery-backed operation during transport or power interruption.
Recommended
Automotive Dashboard Sub-Displays
The PIC16F1936-E/SP supports automotive dashboard sub-display modules where cost-sensitive sub-displays show odometer, trip, or status information. The Extended temperature range handles under-dash thermal environments, the LCD driver drives 96 segments without an external controller, and the EUSART interfaces to the vehicle body controller. Note that AEC-Q100 qualified parts are not in the same MPN family, so use PIC16F1936-E/SP for non-safety automotive subsystems only.
Recommended
IoT Smart Home Sensor Hubs
The PIC16F1936-E/SP enables IoT smart-home sensor hubs because the integrated LCD displays local readings, the EUSART plus I2C interfaces connect to radios or sensors, and nanoWatt XLP enables multi-year battery life. The 14 KB flash runs Zigbee or LoRa stack fragments for simple sensor endpoints, and the CTMU supports capacitive user input. The 32 MHz CPU executes communication stacks within timing budgets, while deep sleep modes below 100 nA preserve coin-cell capacity between transmission intervals.

Design Notes
Estimated: at 32 MHz and 5 V, active current is approximately 8 mA, while sleep current with RTCC on a 32 kHz crystal drops to about 20 nA per Microchip's nanoWatt XLP datasheet. For battery-powered designs, run peripherals at 4 MHz or 8 MHz to keep active power under 5 mA. Use the peripheral module disable (PMD) registers to gate unused peripherals during active mode for additional savings. Plan duty cycle such that active time is less than 1% of total to achieve multi-year battery life from 2xAA cells.
Always configure unused GPIO pins as outputs low (not inputs) to eliminate floating-input quiescent current leakage through the input buffer. The MCLR pin, if unused, must be tied to VDD through a 10 kohm resistor or configured as digital input in configuration words. If using the internal oscillator, do not leave the OSC1/OSC2 pins floating; configure them as digital I/O or tie them off. Failing to do so can add tens of microamps of leakage and disrupt low-power sleep current measurements.
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin and a bulk 10 uF capacitor near the package for transient suppression. For LCD applications, place the LCD segment and common drive traces away from switching nodes and provide a ground plane under the LCD area. Keep the 32 kHz secondary oscillator traces short (under 5 mm) and guard them with ground to minimize noise injection into the RTCC.
When using the ADC for precision measurements, add an external 100 nF + 10 uF RC network on the analog supply pin and route analog signals (ANx) on a separate analog ground island. Use the FVR (Fixed Voltage Reference) module to stabilize ADC reference voltage across temperature. The CTMU module requires careful calibration of current source and time base for repeatable capacitive touch readings; follow Microchip application note AN1250 for capacitive touch design guidelines.
Compliance Information
RoHS compliant and lead-free per Microchip product page. AEC-Q100 qualification is NOT available for PIC16F1936-E/SP - choose PIC16F1936-I/SP automotive variants or other AEC-Q100 qualified parts for safety-critical automotive subsystems. nanoWatt XLP technology supports battery-backed designs but the part is not a certified Safety Integrity Level component.
