PIC16F1516T-I/SS 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (flash/ROM), working memory (RAM), and a set of on-chip peripherals such as timers, ADC, communication interfaces (I²C, SPI, EUSART), and general-purpose I/O. Within the broader taxonomy, the PIC16F1516 is an 8-bit RISC MCU belonging to the PIC16 enhanced mid-range family, which sits under Microchip's 8-bit microcontroller hierarchy and shares the PIC® instruction-set architecture with dsPIC® and PIC18/PIC24 devices.
Key features include an enhanced mid-range core with 49 instructions and 16 stack levels, an internal 16 MHz oscillator, two 8-bit timers (TMR0/TMR2), one 16-bit timer (TMR1), an extended watchdog timer (WDT), and two CCP (Capture/Compare/PWM) modules. Communication is handled by MSSP (I²C/SPI) and an EUSART with auto-baud, while analog capability is delivered by a 17-channel 10-bit ADC with voltage reference. I/O pins source/sink up to 25 mA for direct LED drive.
Typical applications include consumer white goods, motor-control front-ends, IoT sensor nodes, and small-form-factor embedded control where code density, low sleep current, and a wide 1.8-5.5 V supply range matter more than raw MIPS. The wide voltage range allows direct operation from a single Li-ion cell or a 3.3 V regulated rail without level shifters. The 'T' suffix indicates tape-and-reel packaging for high-volume assembly.
A common design pitfall is to leave the unused I/O pins floating - the PIC16F1516 datasheet recommends configuring unused pins as outputs and driving them low. Also, ensure the ADC acquisition time accounts for source impedance (≤10 kΩ) to avoid conversion errors. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that complement the manufacturer datasheet.

主な用途
PIC16F1516T-I/SS の用途: 7 件s: Battery-Powered IoT Sensor Node, Consumer Appliance Control (White Goods), LED Lighting Controller, Industrial Sensor Signal Conditioning, Small Motor Control (DC Brushed / Stepper), Automotive Body Electronics (Non-Safety), Hobbyist / Maker Development Platform.
Battery-Powered IoT Sensor Node
The PIC16F1516T-I/SS's nanoWatt XLP™ technology and 1.8-5.5 V supply make it ideal for battery-powered IoT sensor nodes that wake periodically to read sensors over I²C/SPI and transmit via EUSART (often through a UART-BLE module). With 14 KB of flash and 512 bytes of RAM, the part hosts state-machine firmware plus small command parsers without external memory. The 17-channel 10-bit ADC samples multiple analog sensors directly, while 25 mA I/O source/sink eliminates driver transistors for LED status indicators, shrinking the BOM.
おすすめ
Consumer Appliance Control (White Goods)
The PIC16F1516T-I/SS is widely used as the front-end controller in white-goods appliances such as washing machines, dishwashers, and microwave ovens where the MCU reads keypad/encoder inputs and drives relays or TRIACs. Its two CCP (Capture/Compare/PWM) modules generate PWM outputs to control motor speed or dimming, and the extended WDT provides robust fault recovery in unattended environments. The wide 1.8-5.5 V supply tolerates direct connection to rectified 5 V or 3.3 V rails, while the -40 °C to +85 °C industrial temperature range covers unheated enclosures.
おすすめ
LED Lighting Controller
The PIC16F1516T-I/SS's two CCP PWM modules and 25 mA per-pin source/sink current make it a natural fit for entry-level LED lighting controllers that drive RGB or single-channel constant-current LED strings. The 17-channel 10-bit ADC monitors photodiode feedback for closed-loop dimming or color-mixing, and the EUSART enables DMX-512 or DALI bridge implementations for professional lighting. The 1.8-5.5 V supply permits direct connection to constant-voltage LED driver rails without level shifters.
おすすめ
Industrial Sensor Signal Conditioning
In industrial sensor signal-conditioning front ends, the PIC16F1516T-I/SS reads analog inputs via its 17-channel 10-bit ADC and applies linearization, scaling, and HART-style or MODBUS framing before forwarding the data over RS-485 through the EUSART. The MSSP provides I²C/SPI for digital sensors, while the industrial temperature range and the 1.8-5.5 V supply tolerate noisy 24 V industrial rails with proper TVS protection. The 14 KB flash supports protocol stacks and calibration tables without external EEPROM in many designs.
おすすめ
Small Motor Control (DC Brushed / Stepper)
The PIC16F1516T-I/SS drives small DC brushed or bipolar stepper motors in HVAC dampers, valve actuators, and robotics using its two CCP PWM modules and timer-driven commutation. The EUSART receives command frames from a host controller, the ADC reads shunt-resistor current for over-current protection, and the 20 MHz CPU executes PID loops in real time. The 28-SSOP package and wide operating voltage simplify integration into actuator modules with mixed analog/digital sections.
おすすめ
Automotive Body Electronics (Non-Safety)
Although the -I grade PIC16F1516T-I/SS targets industrial temperature, it is commonly used as a drop-in evaluation MCU for automotive body-electronics prototypes such as interior lighting, seat controllers, and mirror adjusters. Its EUSART supports LIN bus communication, the ADC monitors multiple sensor inputs, and the PWM channels drive LED dimming or motor position control. For production automotive programs, designers typically migrate to an AEC-Q100 qualified PIC16 variant while keeping the same 28-SSOP footprint and firmware architecture.
おすすめ
Hobbyist / Maker Development Platform
The PIC16F1516T-I/SS serves as a teaching and hobbyist MCU thanks to its free MPLAB X IDE, MPLAB Snap debugger/programmer, and XC8 compiler support. With 14 KB of flash, 512 bytes of RAM, and 17 ADC channels, learners can build functional projects from blinking LEDs to small line-following robots using the same device they will later find in commercial embedded products. The 28-SSOP package is breadboard-friendly with SSOP-to-DIP adapter boards widely available.

設計ノート
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 27) of the PIC16F1516T-I/SS, and add a bulk 10 uF tantalum or aluminum capacitor on the same rail if the supply traces exceed 25 mm, per Microchip PIC16(L)F1516/7/8/9 datasheet decoupling recommendations. For nanoWatt XLP™ sleep-current-sensitive designs, use an LDO with <1 µA quiescent current such as the MCP1700 and switch off high-current loads via MOSFETs before entering sleep. Ensure the MCLR reset pin (if not used as reset) is tied to VDD through a 10 kΩ resistor to keep the part out of reset during power-up ramps.
On the 28-SSOP package, route the ICSP clock (PGC, pin 25) and ICSP data (PGD, pin 26) traces away from noisy switching nodes and keep them as short as practical to retain reliable in-circuit programming, per Microchip ICD/debugger layout guidance. Provide a dedicated test pad or header for the ICSP pins so MPLAB Snap or PICkit can connect without removing the MCU. The exposed SSOP pads have 0.65 mm pitch - use NSMD pads with a 0.4 mm solder-mask expansion to minimize solder bridging during reflow.
Configure all unused I/O pins as outputs and drive them low to minimize current leakage through the input structure, per the PIC16(L)F1516/7/8/9 datasheet 'Unused I/O' recommendation. When using the ADC, configure the acquisition time according to the source impedance (≤10 kΩ recommended) to avoid conversion errors; for high-impedance sensors (>10 kΩ) add a unity-gain op-amp buffer such as the MCP6002. Do not exceed 5.5 V on VDD or apply reverse polarity; the part is not reverse-voltage tolerant and will be damaged.
When using the EUSART at the maximum 20 MHz CPU clock with high baud rates (e.g. 115200 or above), verify that the internal oscillator HFINTOSC accuracy meets the target baud-rate error budget (typically <2%) for the chosen receiver, per Microchip PIC16(L)F1516/7/8/9 datasheet timing specifications. For RS-485 or LIN applications, add external TVS protection on the bus pins (e.g. SMAJ24CA) to survive automotive transients. Keep the EUSART TX/RX traces short and routed over a continuous ground reference to minimize radiated emissions on the 28-SSOP pin map.
