PIC16F1519-E/PT 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), working memory (RAM), and programmable peripherals (ADC, timers, communication interfaces) into one device. PIC16F1xxx parts belong to the PIC16 family of 8-bit MCUs, which itself sits within the broader Microchip PIC microcontroller hierarchy (PIC10/12/14/16/18/24/32) - these 8-bit RISC parts target low-power, deterministic, cost-sensitive embedded designs. The "F" suffix denotes Flash-based program memory allowing in-circuit reprogramming, while the "1519" identifies the specific enhanced mid-range device in the PIC16F1516/1517/1518/1519 family scaling in memory and pin count.
Key features of the PIC16F1519 include up to 20 MHz operation from a 1.8 V to 5.5 V supply, eXtreme Low Power (XLP) technology, two Capture/Compare/PWM (CCP) modules, MI2C, SPI, and an EUSART with auto-baud support, plus 25 mA source/sink I/O capability. High-Endurance Flash (HEF) cells provide 128 B of non-volatile data storage, and the device supports on-chip debugging.
The architecture combines a 14-bit instruction word with a Harvard-style bus, automatic interrupt context saving, and selectable internal 16 MHz oscillator. Power-saving sleep modes below 50 nA and a wide 1.8-5.5 V operating range make the part well suited to battery-powered and energy-harvesting designs that still require ADC precision and multiple serial interfaces.
Typical applications include industrial sensor nodes, low-power IoT endpoints, home appliances, white goods control boards, automotive body and interior modules, USB-to-UART bridges, and general-purpose embedded control. Two 8-bit timers (TMR0/TMR2) plus one 16-bit timer provide flexible PWM and event timing.
When designing with the PIC16F1519-E/PT, ensure decoupling capacitors are placed within 5 mm of VDD pins, keep analog and digital grounds separated via a star topology, and budget for at least four layers when routing 28 ADC channels. Avoid using both ADC and digital switching on adjacent pins without isolation.

主な用途
PIC16F1519-E/PT の用途: 6 件s: Industrial Sensor Node, Low-Power IoT Endpoint, Home Appliance Control Board, Automotive Body and Interior Module, USB-to-UART Bridge Dongle, Battery-Powered Data Logger.
Industrial Sensor Node
The PIC16F1519-E/PT suits industrial sensor nodes where multi-channel analog acquisition and deterministic response are required. Its 28 channels of 10-bit ADC with voltage reference let a single MCU scan temperature, pressure, current, and voltage sensors concurrently, while 25 mA source/sink I/O drive simplifies direct interface to relays, optocouplers, and 4-20 mA loops. The 1.8-5.5 V supply accepts 24 V industrial rails after regulation, and the XLP deep-sleep mode below 50 nA extends battery life in remote installations. Two CCP modules generate PWM for valve or motor control; MI2C/SPI/EUSART link to local HMI or upstream PLCs. The 28 KB Flash absorbs protocol stacks (Modbus RTU, IO-Link light) plus application code without external memory. Pair with PIC16F1509-I/SO as a cost-optimized co-MCU for I/O expansion.
おすすめ
Low-Power IoT Endpoint
The PIC16F1519-E/PT is well-matched to low-power IoT endpoints operating from coin cells, two AAs, or energy-harvesting sources. The XLP technology with sub-50 nA sleep current and the wide 1.8-5.5 V supply let the device wake on interrupt, take ADC measurements, transmit over MI2C/SPI, and return to sleep with measured average current in the microamp range. The 1024 B SRAM accommodates small sensor-fusion buffers, while 28 KB Flash holds MQTT-SN, LoRaWAN device driver fragments, or BLE HCI command sequences. EUSART auto-baud enables direct communication with an attached radio module without manual timing calibration. The 44-TQFP exposes enough I/O for local LEDs, pushbuttons, and a UART-controlled radio, replacing more expensive 32-bit parts in cost-sensitive wireless sensor designs.
おすすめ
Home Appliance Control Board
The PIC16F1519-E/PT fits home appliance control boards - washing machines, dishwashers, microwave ovens, induction cookers, and HVAC thermostats - that demand many ADC channels for temperature, water-level, and current sensing. Its 25 mA I/O drive directly switches triac gates, relay coils, and LED indicators without external buffers, reducing BOM cost. Two CCP modules generate the precise PWM required for induction heating or BLDC motor commutation in cost-effective single-MCU designs. The -40 C to +125 C operating range (E suffix) accommodates oven and motor-compartment environments. 28 KB Flash holds the appliance state machine, fault diagnostics, and user-interface logic. EUSART auto-baud enables factory programming and field firmware updates via a service-port UART.
おすすめ
Automotive Body and Interior Module
The PIC16F1519-E/PT operates across -40 C to +125 C (E suffix) with the wide 1.8-5.5 V supply accepted by automotive 12 V rails after regulation. The EUSART supports LIN bus auto-baud with auto-wake-up, enabling cost-effective integration into body control modules, door/window nodes, seat controllers, interior lighting, and HVAC blend-door actuators. Two CCP modules drive small brushed motors or PWM-controlled LED strings; 28 ADC channels measure thermistors, position pots, and current shunts without an external analog front end. 25 mA I/O directly drives FETs for small lamp and motor loads. The 28 KB Flash absorbs LIN node capability, diagnostics (UDS light), and application logic. Note: this is industrial-grade, not AEC-Q100 qualified - for AEC-Q100 applications, choose a Q-graded variant from Microchip's automotive line.
おすすめ
USB-to-UART Bridge Dongle
The PIC16F1519-E/PT, while lacking native USB, fits USB-to-UART or USB-to-SPI bridge dongles when paired with an external USB-serial IC and the PIC16F145x family acting as the USB controller. The 1519 runs the protocol conversion, command parsing, and GPIO control side, taking advantage of its 20 MHz CPU, EUSART with auto-baud, and MI2C/SPI for downstream devices. The 1024 B SRAM holds buffering for high-throughput UART operation, and 28 KB Flash supports CDC, HID, vendor-class, or composite USB stack portions executed on the 145x co-MCU. Engineers frequently pair the PIC16F1459-I/SS as the USB-side device and the PIC16F1519-E/PT as the protocol/translation MCU in compact dongle designs.
おすすめ
Battery-Powered Data Logger
The PIC16F1519-E/PT supports battery-powered data loggers that record sensor data over extended intervals. Its XLP deep-sleep below 50 nA combined with the 16 MHz selectable internal oscillator lets the MCU wake periodically, sample multiple ADC channels, append records to internal SRAM, and return to sleep - achieving years of operation on a coin cell. The 1024 B SRAM stores rolling buffers before flush; 28 KB Flash retains configuration, calibration, and Linear/ring logs across power cycles. EUSART auto-baud allows connection to a host for data retrieval without manual timing configuration. The 44-TQFP exposes pins for SD-card SPI, GPS UART input, and external RTC interrupt. Pair with an external 32.768 kHz crystal for low-power timer-based wake.

設計ノート
Place a 100 nF decoupling capacitor within 5 mm of each VDD pin (the 44-TQFP has multiple VDD pins on different sides), and add a single 10 uF bulk capacitor near the MCU. The wide 1.8-5.5 V supply lets the part operate directly from a 3.3 V regulator output; XLP sleep modes below 50 nA require all unused pins configured as outputs low to eliminate floating-input leakage. Estimate: with three VDD pins and one MCU, four ceramic decouplers in parallel supply transient current during ADC bursts at 20 MHz.
Route analog (ANx) and digital signals on separate layers or with ground guarding; the 28 ADC channels are sensitive to digital switching noise on adjacent pins. Place the VREF reference capacitor (1-10 uF) close to the VREF pin if used. The 44-TQFP (PT) 10x10 mm package has 0.8 mm pitch - use 0.4 mm via-in-pad or dogbone fan-out and consider 4-layer stack-up for clean ADC reference and ground return paths on dense designs.
Do not leave ICSP pins (RB6/RB7) floating - add 10-50 kohm pull-ups to VDD or the device may fail to enter In-Circuit Serial Programming mode during board bring-up. The MCLR pin (RE3) requires a 10 kohm pull-up to VDD if not driven by an external supervisor; tying it directly to VDD disables in-circuit reset. The EUSART auto-baud feature requires a sync byte (typically 'U' or 0x55) on first receive and is not reliable below 2400 baud without character-time calibration.
