PIC16LF707-E/ML - 14KB Flash 8-bit MCU, 1.8-5.5V, 44-VQFN | Microchip
MPN: PIC16LF707-E/ML ✓ Hoạt độngPIC16LF707-E/ML Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals (ADC, timers, communication ports, I/O) into one package. PIC16LF devices sit within the 8-bit PIC microcontrollers -> 8-bit RISC microcontrollers -> microcontrollers -> embedded processors taxonomy, and they target ultra-low-power applications where extended battery life, capacitive touch, and small pin-count packages are mandatory.
Key features include up to 16 MIPS throughput at 32 MHz instruction-cycle input, integrated capacitive-touch mTouch sensing hardware, multiple low-power sleep modes (nanowatt range) for battery-powered applications, an enhanced USART, MSSP for SPI/I2C, a 12-bit ADC with up to 14 channels, and CTMU for capacitive measurement. Compared with PIC16F variants, the LF family lowers core and I/O supply voltage to 1.8V, enabling direct Li-ion/Li-Po battery operation.
Typical applications include capacitive touch key panels for white goods and consumer appliances, low-power handheld medical devices, IoT sensor nodes with touch-based wake, automotive body and HVAC controls, and capacitive proximity/metal-overlap detection modules. The 44-VQFN exposed pad improves thermal dissipation and reduces PCB footprint versus 44-pin TQFP.
Designers should observe the exposed-pad PCB layout requirements of the VQFN: a contiguous ground pad, multiple thermal vias, and a 0.1uF plus 10uF decoupling network placed within millimetres of the supply pins are mandatory for brown-out-free start-up.

Ứng dụng tiêu biểu
PIC16LF707-E/ML phù hợp cho 6 Áp dụngs: Capacitive Touch Appliance Control Panels, Battery-Powered IoT Sensor Nodes, Automotive Body and HVAC Modules, Handheld Medical Measurement Devices, Industrial Sensor and Process Transmitters, Capacitive Proximity and Metal-Overlap Detection.
Capacitive Touch Appliance Control Panels
The PIC16LF707-E/ML's integrated mTouch CTMU peripherals give white-goods and consumer-appliance designers a clean, BOM-light path to multi-button touch keypads, slider controls, and proximity wake. With 14 KB Flash, the part comfortably holds Microchip's touch-sensing firmware libraries plus a real-time UI state machine. The 1.8-5.5 V supply allows direct 3.3 V regulation from a small buck converter, while nanowatt XLP sleep keeps idle current below 100 nA between user touches. The 44-VQFN exposed pad simplifies the slim industrial-design PCBs common in kitchen appliances.

Battery-Powered IoT Sensor Nodes
The PIC16LF707-E/ML is ideal for wireless sensor nodes powered by a single CR2032 or rechargeable Li-ion cell. Its 1.8 V minimum VDD allows direct battery connection without boost circuitry, and the XLP sleep modes drop quiescent current to the nanowatt range between sensor samples. The 12-bit ADC with up to 14 channels handles analog sensors (temperature, humidity, light) while the integrated EUSART drives sub-GHz transceivers or BLE modules. With 14 KB Flash you can fit a real-time operating kernel plus custom protocol stacks for years-long battery life.
Được đề xuất
Automotive Body and HVAC Modules
The PIC16LF707-E/ML's -40 to +125 C automotive temperature grade and 14 KB Flash make it a strong fit for body controllers and HVAC sub-modules. It drives multiple capacitive touch panels, switches, and LEDs while running low-speed CAN diagnostics via EUSART and a CAN transceiver. The 44-VQFN automotive package withstands the vibration and thermal-cycling stresses of under-dash placement, and AEC-Q100 screening of the underlying silicon gives automotive OEMs a reliable baseline. Use the companion PIC16F707E family for higher-temperature engine-bay subsystems.

Handheld Medical Measurement Devices
The PIC16LF707-E/ML's low-power XLP modes extend battery life in portable medical instruments like glucose meters, pulse oximeters, and digital thermometers. Its 12-bit ADC digitizes analog biosensors (photodiode, thermistor, electrochemical cell) with adequate resolution for clinical use, while CTMU supports direct skin-contact temperature measurements. The automotive temperature grade ensures devices stay accurate in refrigerated and outdoor emergency scenarios, and the small 44-VQFN footprint helps shrink the device into pocketable form factors.
Được đề xuất
Industrial Sensor and Process Transmitters
The PIC16LF707-E/ML provides 4-20 mA loop-powered or 24 V industrial bus nodes with 12-bit ADC accuracy and integrated SPI/I2C to talk to digital sensors. Its nanowatt sleep is critical for loop-powered designs that must harvest micro-amps from the 4 mA minimum loop current. The industrial/automotive temperature grade and 44-VQFN ground pad allow direct PCB integration into explosion-proof enclosures, while 14 KB Flash holds calibration tables, linearisation curves, and HART or IO-Link state machines.
Được đề xuất
Capacitive Proximity and Metal-Overlap Detection
The PIC16LF707-E/ML's CTMU peripheral detects capacitive changes induced by hand approach, water films, or metal overlays, ideal for faucet/faucet-touch controllers, automatic doors, and spill-detection electronics. With 14 KB Flash you can run multiple scan routines per panel and event-debounce filters without an external touch ASIC. The 1.8 V VDD floor is essential for solar/battery powered outdoor installations, while the -40 to +125 C range survives freeze/thaw cycles in exterior mounts.

Ghi chú thiết kế
The 44-VQFN (HVQCCN) package dissipates heat through the central exposed pad. The pad MUST be soldered to a contiguous PCB ground copper pour with at least 9 thermal vias (0.3 mm drill, 0.65 mm pitch) to reach the inner ground plane. Without the thermal pad, junction temperature rises rapidly at 16 MHz, especially when the ADC and CTMU are active simultaneously. Estimated: with 9 vias and 1 oz copper, theta_JA falls to approximately 28 C/W versus >50 C/W with no thermal pad.
Decouple VDD with a 100 nF X7R ceramic placed within 2 mm of pin 43 and a bulk 4.7 uF-10 uF X5R near the package. For battery applications, route VDD directly from the cell with a ferrite bead if the design also powers an RF transmitter. Brown-out reset (BOR) should be enabled in the configuration words at a level no higher than the lowest expected battery voltage to avoid false resets during inrush.
Keep the crystal traces (OSC1/OSC2) short, symmetric, and guarded by a ground ring; route analog sensor traces (AN0-AN13) away from the EUSART and SPI lines by at least 3 mm. The exposed pad must remain a single ground net - do not split it into digital and analog zones inside the package footprint, because the die substrate is bonded directly to the pad.
Do not assume any PIC16F727 firmware runs unchanged on PIC16LF707-E/ML - the LF variant adds brown-out threshold options and disables some peripheral features below 2.0 V. Always re-validate the firmware at the lowest and highest VDD corners. Also note that the /ML suffix denotes VQFN package; /PT is TQFP, and although pin-compatible at logical level, the PCB footprint differs.
For capacitive touch sensing, route each CTMU channel as a guarded trace with a ground flood on the adjacent layer and minimum 0.2 mm spacing between channels. Add a 100 ohm series resistor within 5 mm of the MCU pin if the touch electrode is more than 50 mm away to damp RF coupling from the touch bezel. Microchip's mTouch design guide provides detailed EMI immunity recommendations.
