PIC16F1936-E/SS Visão geral
An 8-bit microcontroller (MCU) is a compact computing device built around an 8-bit data bus, optimized for embedded control tasks such as sensor reading, actuator driving, and human-machine interface handling. Within the semiconductor hierarchy, MCUs sit under microcontrollers, which belong to the broader embedded processor family, alongside DSPs and microprocessors. The PIC16F1936 belongs to Microchip's enhanced mid-range PIC16 family, which adds more peripherals, more interrupt sources, and lower power consumption over earlier baseline PIC16 devices, all without sacrificing the iconic single-cycle instruction set.
Key features include a 32 MHz internal oscillator (8 MIPS throughput), 25 digital I/O pins, a 10-bit ADC with up to 14 channels, multiple PWM and capture/compare modules, an mTouch capacitive-sensing peripheral, and nanoWatt XLP extreme-low-power technology with sleep currents under 50 nA typical. The integrated LCD controller supports static, 1/2, 1/3, and 1/4 multiplex modes, and supplies the charge-pump bias voltages needed for contrast.
The device uses a modified Harvard RISC architecture with separate program and data buses, executed through a 14-bit instruction word. An on-chip In-Circuit Serial Programming (ICSP) interface and In-Circuit Debug (ICD) support allow field updates and real-time development without removing the part. The SSOP-28 footprint offers a compact outline while keeping 0.65 mm pitch manageable for hand-soldered prototypes.
Typical applications include consumer appliances with LCD front panels, battery-powered sensor nodes, medical measurement devices with character displays, industrial control keypads with segment LCDs, and metering equipment such as electricity or water meters. The wide voltage range and low-power modes support both line-powered and battery-backed designs.
When designing with this part, prioritize assigning analog and digital functions to pins that retain their capability at the chosen VDD - some peripherals disable below 2.0V. Use a 100 nF decoupling capacitor adjacent to VDD, and route the segment/commons to the LCD with short, equal-length traces. For noise-sensitive ADC readings, configure the part to enter Sleep between conversions.

Aplicações típicas
PIC16F1936-E/SS é adequado para 6 aplicaçãos: Battery-Powered Metering with Segment LCD, Consumer Appliance Control Panel, Industrial Sensor and Keypad Module, Medical Point-of-Care Device, IoT Sensor Node with Local Display, Automotive Dashboard Accessory.
Battery-Powered Metering with Segment LCD
The PIC16F1936-E/SS is ideal for electricity, water, and gas meters thanks to its integrated segment LCD driver (up to 96 segments), nanoWatt XLP sleep current below 50 nA, and 1.8V to 5.5V supply range covering both 3.6V lithium-thionyl-chloride and 3V CR2032 cells. With 14 KB flash and 512 bytes RAM, the part accommodates metering firmware with calibration tables, tariff schedules, and LCD driver routines in a single MCU without an external LCD chip. The 32 MHz internal oscillator simplifies BOM by removing the external crystal for most designs, while its 14-channel 10-bit ADC captures sensor signals from current shunts or pulse counters. Practical placement: route segment pins to the LCD glass via short equal-length traces, and put the MCU into Sleep between ADC conversions to extend battery life to 10+ years.
Recomendado
Consumer Appliance Control Panel
The PIC16F1936-E/SS fits washing machines, microwave ovens, and HVAC thermostats where a character LCD or segment display is paired with capacitive touch buttons. The on-chip mTouch capacitive-sensing peripheral removes the need for an external touch IC, while the integrated LCD controller drives a 4-mux display directly from the 5V supply without a charge-pump circuit. With 25 I/O pins, the MCU controls relays, triacs, and a buzzer directly while reading temperature sensors via its 10-bit ADC. Use the PIC16F1936-E/SS in the SSOP-28 footprint to keep the PCB compact behind a glass front panel. Its -40C to +125C operating range handles oven and boiler ambient conditions without derating.
Recomendado
Industrial Sensor and Keypad Module
The PIC16F1936-E/SS works well in industrial sensor transmitter modules with on-board LCD indication, where 4-20 mA loop or RS-485 output is paired with a local display for commissioning. The E-grade temperature rating up to +125C supports installation near motors and inside control cabinets. With EUSART, MSSP I2C/SPI, and 10-bit ADC, the part interfaces to digital sensors, HMI keypads, and external EEPROM or RTC chips. The 14 KB flash is enough for sensor linearization tables, calibration data, and protocol stacks. Its nanoWatt XLP sleep modes make it suitable for loop-powered 4-20 mA devices drawing under 3.5 mA total. Use SSOP-28 to keep the module footprint below 10x20 mm.
Recomendado
Medical Point-of-Care Device
The PIC16F1936-E/SS suits compact medical measurement devices such as blood pressure monitors, glucometers, and pulse oximeters that use a monochrome segment LCD. The 10-bit ADC with 14 channels captures signals from pressure sensors, thermistors, and reflectance oximetry photodiodes. The mTouch peripheral enables capacitive buttons that seal the front panel to IPX4 splash rating. With 1.8V to 5.5V supply, the MCU runs from two AAA cells or a single lithium coin cell. Use the PIC16F1936-E/SS for FDA Class II devices where a stable, long-life MCU is required. The 256-byte EEPROM stores calibration data and patient log entries without an external memory chip.
Recomendado
IoT Sensor Node with Local Display
The PIC16F1936-E/SS powers IoT edge nodes that display readings locally on a segment LCD while communicating over UART or SPI to a wireless module such as LoRa or BLE. The integrated LCD controller removes the need for a separate display driver chip, and the mTouch peripheral supports touch-based wake-up from sleep for user interaction. With nanoWatt XLP sleep current below 50 nA, battery life exceeds 5 years on a 2400 mAh AA cell when reporting every 60 seconds. The 32 MHz internal oscillator eliminates external timing components. Choose this part for thermostats, environmental monitors, and asset trackers where a local LCD shows last-known value without requiring a smartphone app.
Recomendado
Automotive Dashboard Accessory
The PIC16F1936-E/SS handles aftermarket automotive accessories such as digital tire pressure displays, gear-position indicators, and auxiliary fuel gauges with segment LCD readouts. The E-grade +125C temperature rating tolerates cabin and engine-bay ambient conditions. The integrated LCD controller drives 7-segment style displays for numeric readouts, while the mTouch peripheral supports capacitive buttons on the dashboard bezel. With 25 I/O pins, the part interfaces to CAN or LIN transceivers via its EUSART for vehicle bus connectivity. The wide 1.8V to 5.5V supply range accepts 12V battery rails through a linear regulator. Choose E-grade specifically because automotive under-hood ambient temperatures frequently exceed +85C.

Notas de projeto
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pins 26 and 27, plus a bulk 10 uF tantalum or ceramic on the same rail. The PIC16F1936-E/SS has two VDD pins that must both be connected to avoid logic errors during Sleep mode entry. For battery designs, switch the LCD charge pump off when the display is blanked to save 1-2 uA. Place a low-ESR 1 uF bypass on AVdd if you use the ADC.
The SSOP-28 package dissipates up to 800 mW at full 32 MHz operation across -40C to +125C. In practice the part draws under 10 mA active and well under 1 mA idle, so thermal management is rarely a concern. For continuous high-load designs, compute worst-case power: VDD_max (5.5V) x I_active (8 mA) = 44 mW, far below the 800 mW rating. Keep the GND pin (7) tied to a low-impedance copper pour.
Route the segment and common LCD traces as short, equal-length parallel lines away from noisy digital signals. The datasheet recommends a 0.1 mm trace width and 0.15 mm spacing for SSOP-based designs. Place a guard ring around the mTouch sensor pins to prevent false triggers from adjacent signals. Keep the ICSP header (RB6/RB7) accessible for in-circuit debugging without removing the MCU from the board.
Do not leave the MCLR pin floating - tie it to VDD through a 10 kohm resistor to enable normal operation. If programming in-circuit, add a series resistor and Schottky diode to MCLR per Microchip's ICSP design notes. Do not exceed the 5.5V absolute maximum on any pin or you will damage the part. When migrating from PIC16F1934 firmware, verify that the larger RAM and flash layout do not break any hard-coded memory addresses in your linker script.
