PIC16LF1936-E/SO - 14KB Flash 8-bit MCU 28-SOIC | Microchip
MPN: PIC16LF1936-E/SO ✓ Hoạt độngPIC16LF1936-E/SO Tóm tắt
An 8-bit flash microcontroller is a single-chip computer built around an 8-bit data path with on-chip Flash program memory that can be erased and reprogrammed in-circuit. The PIC16LF1936 belongs to the microcontrollers -> MCU -> 8-bit MCU -> embedded controllers -> semiconductor taxonomy and is widely deployed in cost-sensitive, low-power, and human-machine-interface (HMI) products that need integrated LCD drive.
Differentiating features of the PIC16LF1936-E/SO include a dedicated on-chip LCD driver supporting up to 28/40/44 segments across the family, 14 KB of Flash for embedded firmware, 256 bytes of EEPROM for non-volatile user data, nanoWatt XLP for sub-microamp sleep currents, and 36 I/O ports sharing bus functions with the LCD driver. A 10-bit ADC with multiple channels supports sensor interfacing, while an internal oscillator reduces external component count.
Architecturally, the PIC16LF1936 uses an enhanced mid-range PIC16 core with 200 ns instruction execution, a 16-level hardware stack, and Harvard bus architecture with separate instruction and data paths. The LCD driver integrates charge pump and bias generation, eliminating external resistor ladders. XLP technology uses dynamic power management of peripherals and a deep-sleep mode to reach nanoamp idle currents.
Typical applications include white goods and small appliance HMI panels, thermostat and HVAC control units, battery-powered IoT sensor nodes with LCD readouts, consumer remote controls, and metering/utility display boards where integrated LCD drive reduces BOM cost. The 28-SOIC footprint also supports hand-soldered prototypes and hand-rework on legacy board designs.
When designing with this MCU, allocate enough program memory headroom - 14 KB of Flash supports moderate firmware but complex graphics stacks can exhaust it quickly. The on-chip LCD driver assumes static or 1/4 duty multiplexed glass; verify segment counts match your LCD before committing. The 'LF' low-voltage variant disables operation above 3.6 V - use the PIC16F1936 (standard F) variant if a 5 V rail is required.

Ứng dụng tiêu biểu
PIC16LF1936-E/SO phù hợp cho 6 Áp dụngs: Thermostat and HVAC Control with LCD, Battery-Powered IoT Sensor Node with LCD, White Goods and Small Appliance HMI, Consumer Remote Control with LCD Display, Utility Meter and Energy Monitor Display, Industrial Process Indicator Panel.
Thermostat and HVAC Control with LCD
The PIC16LF1936-E/SO is purpose-built for thermostat and HVAC control units because it integrates an on-chip LCD driver supporting up to 28 segments in the 28-SOIC package - eliminating the external HT1621 or similar segment LCD controller. Its nanoWatt XLP technology delivers sub-microamp sleep currents, allowing multi-year battery life on 2xAA cells for wireless thermostat nodes, while the -40C to +125C E temperature grade handles unconditioned wall-box environments. The 14 KB Flash holds thermostat scheduling firmware, and the 256-byte EEPROM stores user setpoints across power cycles. Place the part on a compact 28-SOIC footprint with a CR2032 backup supercap.

Battery-Powered IoT Sensor Node with LCD
The PIC16LF1936-E/SO fits battery-powered IoT sensor nodes that need a local LCD readout, because its 1.8-3.6 V LF Vdd range allows direct operation from a CR2032 or 2xAA pack without boost conversion. The 32 MHz CPU runs the radio protocol and sensor acquisition while idle, and nanoWatt XLP deep-sleep drops the current below 1 microamp for 99% duty-cycled duty cycle. The 10-bit ADC drives analog sensors (temperature, humidity, light) and the LCD driver shows live readings without a host MCU. Expected coin-cell life exceeds 5 years at 1 reading per minute.

White Goods and Small Appliance HMI
The PIC16LF1936-E/SO is ideal for white goods HMI panels (rice cookers, washing machines, microwave ovens) because the integrated LCD driver removes an external HT1621-equivalent chip, reducing BOM cost by $0.20-$0.30 per unit. The 32 MHz core supports capacitive-touch button scanning and rotary encoder handling in real time, and 36 I/O pins drive LEDs, buzzers, and relay controls. The 14 KB Flash holds multi-mode appliance firmware with custom wash cycles or cook programs. Industrial -40C to +125C E grade handles kitchen heat and humidity stress.
Được đề xuất
Consumer Remote Control with LCD Display
The PIC16LF1936-E/SO suits premium remote controls with status LCDs (universal remotes, smart-home hubs) because the integrated segment LCD driver and nanoWatt XLP technology deliver long battery life while showing menus, IR codes, and battery state. The 32 MHz CPU handles IR transmission protocols (RC5, NEC, SIRC) while the LCD driver shows channel listings or device pairing screens. Pin count supports multiple IR LEDs, key matrix scanning, and capacitive touch, all on a single CR2032 or 2xAAA cell.
Được đề xuất
Utility Meter and Energy Monitor Display
The PIC16LF1936-E/SO is well suited for utility metering and energy monitoring front-panel displays because the on-chip LCD driver supports multi-digit seven-segment and symbol LCDs without an external charge pump. The 10-bit ADC samples current/voltage sense signals at rates up to 100 kSPS for power calculation, and 256 bytes of EEPROM stores tamper logs and calibration constants. The -40C to +125C E grade handles outdoor meter enclosures, and the 1.8-3.6 V Vdd allows direct battery backup during line-power outages.
Được đề xuất
Industrial Process Indicator Panel
The PIC16LF1936-E/SO drives industrial process indicator panels where a local LCD shows tank level, pressure, or flow rate without a full PLC. The 10-bit ADC interfaces with 4-20 mA current-loop sensors via an external sense resistor, and the on-chip LCD driver renders numeric and bar-graph displays. The 32 MHz core handles Modbus RTU or HART communication and runs a PI control loop if needed. The -40C to +125C E temperature grade handles factory floor conditions, and the 28-SOIC footprint supports through-hole retrofits into legacy panels.

Ghi chú thiết kế
The PIC16LF1936-E/SO operates from 1.8 V to 3.6 V Vdd on the LF variant. For 5 V systems, substitute the F-variant PIC16F1936-E/SO. Add a 100 nF decoupling capacitor close to each Vdd pin (pins 7 and 17), and a bulk 10 uF tantalum or ceramic capacitor on the supply rail. Place a ferrite bead on Vdd if the LCD charge pump injects switching noise back into the analog supply; the on-chip charge pump runs at ~4 kHz.
Route the ICSP signals (PGC/RB6, PGD/RB7) to a 6-pin header or test pad for in-circuit programming and debug. The MCLR/VPP pin (pin 1) requires a 10 kohm pull-up to Vdd and a 100 nF cap to ground for proper reset. Keep analog traces (ADC inputs) short and away from digital switching signals; the 10-bit ADC is moderately noise-sensitive. Connect the AVdd/AVss pins to the same Vdd/Vss planes with ferrite isolation if precision ADC readings are required.
Do not assume the LF silicon works at 5 V - brown-out or latch-up can occur above 3.6 V. Always select the LF or F variant explicitly when ordering. The on-chip LCD driver assumes static or 1/4 duty multiplexed segment glass - verify segment count matches your LCD before committing to PCB layout, especially when migrating from the larger PIC16LF1937/1938 parts. Finally, the E temperature grade -40C to +125C costs roughly 10-15% more than the I grade - only choose E if your enclosure demands it.
The on-chip LCD driver uses a charge pump that injects ~1 mV ripple on Vdd at 4 kHz. For mixed-signal designs sharing the same rail with a precision ADC, isolate the charge pump with a small LC filter (10 uH + 10 uF) or use the internal charge pump disable and an external discrete boost. Disable unused peripherals in firmware to minimize dynamic current draw and lower the noise floor on the 10-bit ADC readings.
