PIC16LF1507T-I/ML 概述
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data bus and a Harvard-architecture CPU optimized for deterministic, byte-oriented control tasks. Within the broader semiconductor hierarchy, an 8-bit MCU belongs to the microcontroller family, which sits under microcontrollers and embedded processors in the taxonomy of digital ICs. The PIC16LF1507 specifically implements Microchip's enhanced mid-range core with 49 instructions, 16-level hardware stack, and self-read/write Flash, giving it deterministic interrupt latency useful for real-time control loops.
Key features of the PIC16LF1507T-I/ML include the integrated 16 MHz internal oscillator (selectable up to 20 MHz via PLL configuration), 18 GPIO pins multiplexed with peripheral functions, a 10-bit ADC with up to 12 channels and internal voltage reference, four 10-bit PWMs with independent time bases, a Numerically Controlled Oscillator (NCO), a Complementary Waveform Generator (CWG), two Configurable Logic Cells (CLC), and an integrated temperature indicator. The LF process node targets sub-1 uA sleep currents for battery applications.
The 20-pin QFN-4x4 package with exposed thermal pad provides low thermal resistance for the internal linear regulator and ground connection. Designers can configure the part for either an internal RC oscillator or an external crystal, and the ICSP (In-Chip Serial Programming) interface allows in-circuit firmware updates without removing the part from the board.
Typical applications include consumer electronics remote controls, IoT sensor nodes with sleep-mode duty cycling, low-cost LED lighting controllers with dimming/PWM, battery-powered handheld instruments, and home appliance user-interface boards. The combination of small Flash, low pin count, and 1.8V minimum VDD makes it attractive for cost-sensitive, space-constrained designs.
When designing with this part, evaluate whether 3.5KB Flash is sufficient for your application including bootloader overhead, plan for a 100 nF decoupling capacitor placed within 3 mm of VDD, and connect the exposed pad (EP) to the ground plane for thermal and electrical performance. For designs requiring more Flash or peripherals, consider the PIC16F1507 (5V-tolerant variant) or PIC16LF1509.

典型应用
PIC16LF1507T-I/ML 适用于 6 应用s: Consumer Remote Control MCU, IoT Sensor Node (Battery-Powered), LED Lighting Controller, Battery-Powered Handheld Instrument, Home Appliance User-Interface Board, Toy and Hobby Electronics Module.
Consumer Remote Control MCU
The PIC16LF1507T-I/ML suits consumer IR/RF remote controls where 3.5KB Flash fits IR protocol state machines and button-debounce firmware. The LF process delivers sub-microamp sleep current essential for AAA-battery remotes that idle for years. The 1.8V minimum VDD allows direct Li coin-cell drive without boost converters. The integrated 16 MHz oscillator eliminates external crystals, reducing BOM cost. Designers place the part in Sleep mode between button events, wake via IOC (interrupt-on-change) on RA pins, then transmit via CWG-driven carrier. The 20-QFN (4x4 mm) footprint fits inside slim remote enclosures.
推荐
IoT Sensor Node (Battery-Powered)
For wireless sensor endpoints transmitting periodically over BLE/sub-GHz radios, the PIC16LF1507T-I/ML offers enough Flash (~3.5KB) for stack-light sensor preprocessing while its LF process node yields nanoamp Sleep currents measured in industry datasheets. The 1.8V minimum VDD enables direct Li-MnO2 coin-cell operation. The 10-bit ADC scans up to 12 channels (temperature, humidity, battery voltage) without external analog. The integrated 16 MHz oscillator keeps BOM minimal, and the CWG peripheral can generate sub-GHz carrier frequencies directly without an external synthesizer. The /ML QFN-20 4x4 mm package supports dense PCB layouts alongside radio modules.
推荐
LED Lighting Controller
The PIC16LF1507T-I/ML drives LED strips and fixtures via its four 10-bit PWM channels and the Complementary Waveform Generator (CWG). The CWG can produce synchronized complementary outputs for half-bridge LED drivers, while the PWMs handle RGB color mixing at 8-bit effective resolution. The 1.8V-3.6V range covers single-cell Li-ion and 3.3V regulated rails found in smart-bulb designs. The integrated temperature indicator enables thermal foldback without external NTC sensors. The 20-QFN package fits inside MR16 / GU10 form factors where space is constrained.
推荐
Battery-Powered Handheld Instrument
The PIC16LF1507T-I/ML serves as the main MCU in handheld multimeters, digital thermometers, and laser distance meters where 3.5KB Flash accommodates UI firmware and the LF process maximizes battery life. The 10-bit ADC at 12 channels handles sensor multiplexing (thermocouple, battery monitor, reference). The integrated temperature indicator calibrates measurement drift. The /ML QFN-20 4x4 mm package is small enough for pen-style housings. Microchip's nanoWatt XLP technology keeps Iq below 20 nA in Sleep mode, enabling years of shelf life on primary cells.
推荐
Home Appliance User-Interface Board
Coffee makers, washing-machine sub-panels, and microwave keypads use the PIC16LF1507T-I/ML as the user-interface controller interfacing with capacitive/segmented touch sensors and 7-segment displays. The IOC feature handles low-power button polling. The CWG peripheral drives buzzers or triac timing for heating elements. The 1.8V-3.6V VDD aligns with rectified 3.3V auxiliary rails in white goods. The 20-QFN package is small enough to embed inside front-panel overlays. The industrial -40C to +85C grade covers kitchen and laundry-environment temperature ranges.
推荐
Toy and Hobby Electronics Module
The PIC16LF1507T-I/ML is widely used in STEM-class microcontroller boards, RC servo controllers, and hobby robotics where its combination of low price (sub-$0.50 at high volume per LCSC) and small footprint attracts builders. The four PWMs drive hobby servos or motor drivers. The 20-QFN-4x4 package fits on coin-sized PCBs. The integrated 16 MHz oscillator removes external crystal cost. The internal temperature indicator teaches students ADC programming basics. Microchip's free MPLAB X IDE with XC8 C compiler makes the PIC16LF1507T-I/ML accessible to hobbyists and educational programs.

关键差异点
- Low-power LF process for sub-1 uA Sleep current （对比 PIC16F1507-I/ML)
- Compact 4x4 mm QFN-20 footprint （对比 PIC16LF1507T-I/SS (SSOP-20))
- Tape-and-reel ('T') packaging for high-volume assembly （对比 PIC16LF1507-I/ML (tray))
设计说明
Place a 100 nF decoupling capacitor within 3 mm of the VDD pin (pin 11) and a bulk 1-10 uF capacitor on the supply rail. The LF process supports Sleep currents below 1 uA when configured with WDT disabled and LFINTOSC in low-power mode. Always connect the exposed pad (EP) to GND for thermal relief and noise immunity.
Route RC0/RC1 carefully if used as ICSP (In-Chip Serial Programming) - keep traces short to the programming header and avoid series resistors above 100 ohm on ICSPDAT/ICSPCLK. For ADC accuracy (10-bit), isolate analog traces (AN0-AN9) from digital switching signals; place the analog ground star-point at the EP.
Do not exceed 3.6V on VDD or apply voltage to any pin before VDD is stable - this can latch-up the part. The MCLR pin (pin 1) requires a 10 kohm pull-up to VDD if not driven externally. Ensure the configuration bits disable the watchdog unless your firmware specifically handles the WDT ISR, otherwise unintended resets will occur.
合规信息
PIC16LF1507T-I/ML is RoHS-compliant per Microchip product page; package finish is lead-free matte tin. The LF process variants are not AEC-Q100 qualified; Microchip recommends the 'F' (non-LF) variants for automotive qualification paths.
