PIC16LF1936T-I/MV 概述
An 8-bit microcontroller is a single-chip computer built around an 8-bit data bus, an ALU, program memory, and a fixed set of peripherals. It belongs to the broader hierarchy of microcontroller -> embedded controller -> semiconductor device, and within the PIC architecture it sits in the enhanced mid-range PIC16F/LF193x family that adds LCD drive, mTouch capacitive sensing, and nanoWatt XLP sleep modes to the classic PIC16 instruction set.
Key features include an operating voltage range of 2.3V to 3.6V optimized for battery-powered designs, support for up to 36 I/O pins remappable through the peripheral pin select (PPS) system, a 32MHz internal oscillator, and multiple low-power sleep modes drawing well under 1 microamp. The integrated LCD driver supports up to 96 segments with software-controlled contrast, and the mTouch peripheral enables capacitive touch buttons without external components.
The architecture combines a RISC Harvard-style CPU with peripheral pin select, a 10-bit ADC with computation, multiple Enhanced USART, SPI, and I2C interfaces, plus capacitive sensing hardware. The XLP technology delivers sleep currents below 100 nA typical, with RTCC, watchdog timer, and ultra-low-power wake sources that keep standby power well below competing 8-bit cores.
Typical applications include battery-powered sensor nodes, consumer remote controls, small household appliances with segmented LCD displays, capacitive touch user interfaces, and metering devices such as thermometers and electricity meters where the LCD driver and XLP are the dominant feature requirements. The wide operating voltage also suits direct 3V coin-cell designs.
When designing with the PIC16LF1936T-I/MV, ensure that VDD decoupling uses a 100nF ceramic capacitor placed within 5 mm of the package pin, and that the exposed thermal pad (EP) is soldered to a grounded copper pour for both thermal dissipation and mechanical reliability of the UQFN-28 (MV) body.

典型应用
PIC16LF1936T-I/MV 适用于 6 应用s: Battery-Powered Sensor Node, Household Appliance LCD User Interface, Capacitive Touch Keypad, Thermometer / Metering Device, Consumer Remote Control, Small Appliance Control Board.
Battery-Powered Sensor Node
The PIC16LF1936T-I/MV is well-suited for battery-powered sensor nodes where its nanoWatt XLP sleep currents below 100 nA typical enable multi-year battery life on a CR2032 coin cell. The 32 MHz CPU wakes briefly to sample a temperature or humidity sensor via I2C, applies median filtering in firmware, then returns to deep sleep with RTCC-only active. The 256 B SRAM supports a circular sample buffer without RAM overflow, and the integrated 10-bit ADC ADC2 handles analog sensor channels at up to 100 ksps without external analog peripherals. Compared to an 8051-class MCU, the PIC core saves 30-50% sleep power at the same supply voltage.
推荐
Household Appliance LCD User Interface
The PIC16LF1936T-I/MV drives segmented LCD displays in microwaves, washing machines, and thermostats with its integrated LCD controller supporting up to 96 segments at 2.3-3.6 V without external bias generation. The mTouch capacitive sensing peripheral replaces mechanical buttons with capacitive sliders and wheels, reducing BOM cost. The 32 MHz CPU executes custom character LCD UI updates at 60 Hz without flicker, and the 14 KB Flash holds multilingual menu trees plus PID-control firmware. The 36 I/O pins remappable through PPS accommodate additional relays, triacs, and rotary encoders on the same board.
推荐
Capacitive Touch Keypad
The PIC16LF1936T-I/MV replaces mechanical keypads with up to 16 capacitive touch buttons through its CTMU (Charge Time Measurement Unit) peripheral without external touch ICs. The mTouch library walks a hardware-accelerated scan loop at 32 MHz CPU speed, decoding multi-touch gestures in firmware. The XLP sleep mode drops below 1 microamp between key presses, ideal for IoT door locks and smart-home remote controls where battery life exceeds three years on two AA cells. The 14 KB Flash accommodates mTouch library (4 KB) plus application firmware (8-9 KB) in a single-chip design.
推荐
Thermometer / Metering Device
The PIC16LF1936T-I/MV is ideal for digital thermometers and metering devices where its integrated LCD driver and nanoWatt XLP technology drive a 3-4 digit 7-segment LCD display on a single CR2032 coin cell for 5+ year battery life. The 32 MHz CPU executes the math for analog-to-temperature conversion using the internal bandgap reference and an external thermistor. The 10-bit ADC ADC2 with computation performs oversampling and averaging in hardware, freeing CPU cycles for display refresh. The 256 B EEPROM stores calibration constants and last-known meter readings across battery swaps without external memory.
推荐
Consumer Remote Control
The PIC16LF1936T-I/MV handles IR remote control encoding (RC5, NEC, SIRC) plus capacitive touch keys in a single chip with its 32 MHz CPU and integrated mTouch peripheral. The XLP technology delivers typical sleep currents below 1 microamp, so a coin-cell-powered remote control easily lasts 5-7 years. The 256 B EEPROM stores pairing codes, and the EUSART peripheral can support Bluetooth Low Energy modules via serial passthrough. The 36 I/O pins through PPS support LED indicators, IR LEDs, and key matrix scanning simultaneously.
推荐
Small Appliance Control Board
The PIC16LF1936T-I/MV controls small home appliances such as coffee makers, kitchen scales, and humidifiers where its 36 I/O pins through PPS interface directly to triac drivers, zero-cross detectors, and rotary encoders. The hardware PWM channels drive Peltier coolers and pump motors without CPU intervention, freeing CPU cycles for safety monitoring and user-interface logic. The nanoWatt XLP technology enables standby power below 0.5 W to satisfy EU regulatory standby limits for white goods. The 256 B EEPROM stores user presets that persist across power cycles.

设计说明
Place a 100 nF X7R ceramic decoupling capacitor within 5 mm of the VDD pin (pin 28) on the PIC16LF1936T-I/MV, plus a bulk 1 uF to 10 uF capacitor on the same node to handle CPU current spikes at 32 MHz operation. For battery applications using coin cells, add a bulk 1 uF capacitor on the unregulated battery rail to stabilize the load. The XLP sleep modes drop below 1 microamp when RTCC and watchdog timer are disabled, so quiescent draw is dominated by external regulators and pull-ups.
The 28-UQFN (MV) package exposes an EP (exposed pad) on the underside labelled as pin 20 (VSS_PAD). This pad must be soldered to a grounded copper pour of at least 16 mm2 (4x4 thermal pad minimum) for thermal reliability and mechanical stability. Without soldered EP, the UQFN package will satisfy neither board-level reliability nor thermal dissipation requirements, particularly at elevated ambient temperatures.
Programming pins RB6 (ICSPDAT) and RB7 (ICSPCLK) on the PIC16LF1936T-I/MV lack inherent weak pull-ups by default, so an in-circuit serial programmer (ICSP) connection requires 4.7 kohm external pull-ups to VDD to ensure clean logic-level transitions during programming. Designers leaving these pins as general-purpose I/O without pull-ups encounter programming failures in production. The ICSP connector footprint should be reserved even if not initially populated.
For PCB layout of the PIC16LF1936T-I/MV, keep analog input traces (AN0-AN7) as short as possible and route them over a continuous ground plane to minimize ADC2 noise pickup. Add a ferrite bead between digital and analog VDD rails if the design uses analog peripherals alongside switching converters. The 32 MHz CPU generates clock harmonics up to 160 MHz, so SSO (simultaneous switching output) trace lengths should be matched where multiple outputs toggle in parallel.
