PIC16F19175T-I/PT 概要
An 8-bit PIC microcontroller is a Harvard-architecture RISC device widely used in embedded control. MCUs sit within the broader taxonomy of microcontrollers -> embedded processors -> semiconductors; within Microchip's portfolio, PIC16 devices fill the mid-range 8-bit niche between baseline PIC10/12 and high-performance PIC18/DSPIC. Compared with 32-bit Cortex-M parts, PIC16 MCUs offer simpler toolchains, lower cost, and lower active current for cost-sensitive applications.
Differentiating features of the PIC16F19175 include an integrated charge pump and high-current I/O for direct LCD display drive, hardware CRC/SCAN, Windowed Watchdog Timer (WWDT), Hardware Limit Timer (HLT), Core Independent Peripherals (CIPs), Intelligent Analog peripherals such as a 12-bit ADC and 5-bit DAC, and on-chip EEPROM for non-volatile user data. The 32 MHz internal oscillator eliminates an external crystal in many designs.
The architecture combines a single-cycle PIC16 ALU with a unified peripheral set that can operate without CPU intervention, reducing active time and average power. The XLP Sleep mode draws extremely low current, allowing battery designs to wake only for short measurement events. Separate analog/digital supply pins and a wide operating voltage range (typically 1.8 V to 5.5 V) further simplify portable designs.
Typical applications include battery-powered LCD meters, white-goods and appliance user interfaces, IoT sensor nodes, and industrial control panels. The integrated charge pump and segment/segment-common LCD driver make the part especially suited for character or segment LCDs without external biasing hardware.
Designers should evaluate RAM and Flash headroom carefully: 1 KB SRAM and 14 KB Flash fit only modest stacks and feature sets. For code migration, the same PIC16F191xx silicon is offered in smaller packages (e.g., 28-pin SPDIP/SOIC) allowing PCB layout reuse.

主な用途
PIC16F19175T-I/PT の用途: 7 件s: Battery-Powered LCD Meter (Gas/Water/Heat), Home Appliance User Interface (HMI), Industrial Sensor Transmitter (4-20 mA / Wireless), IoT / Smart-Sensor Edge Node, Automotive Interior Accessory (Cluster / HVAC panel), Portable Medical / Wellness Devices, RF-Controlled Toy and Consumer Device.
Battery-Powered LCD Meter (Gas/Water/Heat)
The PIC16F19175T-I/PT's integrated segment LCD driver with on-chip charge pump and XLP Sleep at nanoWatt-level current makes it ideal for battery-powered metering. The device can drive a 4-mux to 8-mux segment LCD directly from the MCU pins, eliminating external bias networks and reducing BOM. With 14 KB Flash, the firmware supports segmented displays, tamper detection, IEC 62056-21 logging, and multi-tariff schedules. The 32 MHz core delivers responsive button/keypad feedback and Quick Wake from Sleep using the Windowed Watchdog Timer.
おすすめ
Home Appliance User Interface (HMI)
The PIC16F19175T-I/PT serves as the user-interface and housekeeping MCU in white goods such as washing machines, dishwashers and ovens. CRC/SCAN and the Hardware Limit Timer (HLT) provide safety and IEC 60730 class B support. The CWG, complementary waveform generator plus Enhanced PWM support BLDC control loops when paired with an MCU gate driver. Integrated LCD drive lets the appliance show cycle status without an additional display driver. CIPs offload cap-touch and rotary-encoder decoding from the CPU, keeping average active current low for energy-star compliance.
おすすめ
Industrial Sensor Transmitter (4-20 mA / Wireless)
For 4-20 mA loop-powered or wireless sensor transmitters, the PIC16F19175T-I/PT's 12-bit ADC plus 5-bit DAC are exactly what is needed to read RTD, thermocouple, and process-current signals accurately. The Windowed Watchdog Timer (WWDT) and CRC/SCAN deliver the diagnostic coverage required by IEC 61508 SIL-1 designs. Sleep current under 1 uA extends battery life in wireless-variants. Hardware Limit Timer offloads frequency-to-voltage conversion without CPU intervention, lowering effective active duty cycle and lowering total power budget by up to 50% versus CPU polling.
おすすめ
IoT / Smart-Sensor Edge Node
The PIC16F19175T-I/PT works as a sensor-edge MCU that can wake, sample, and transmit over UART via a low-power RF module like LoRa or Sub-GHz. The internal 32 MHz oscillator eliminates an external crystal, and XLP Sleep plus a periodic Windowed Watchdog wake give active duty cycles below 0.1%. CIP-enabled CLC logic constructs hardware timer/state machines, letting the device operate autonomously and only interrupt the host CPU for full-events. 14 KB Flash accommodates LoRaWAN Class A/C protocol stacks with room for application firmware.
おすすめ
Automotive Interior Accessory (Cluster / HVAC panel)
For non-safety automotive interiors such as HVAC control heads and seat modules, the PIC16F19175T-I/PT provides the LCD, ADC and PWM channels needed in a single chip. While the part is not AEC-Q100 qualified (select automotive-grade PIC16F1xxx instead), it is widely used in commercial vehicle interior circuits. The Hardware Limit Timer (HLT) provides PWM fault detection for backlight drivers and motor torque monitoring. Designers needing AEC-Q100 should reference the PIC16F15376-I/PT automotive part number family with the same 44-pin TQFP outline.
おすすめ
Portable Medical / Wellness Devices
Portable medical and wellness devices such as TENS units, glucose meters and pill dispensers benefit from the PIC16F19175T-I/PT's integrated 12-bit ADC, on-chip segment LCD, and ultra-low Sleep current. The part is well-suited to designs that must operate on a coin cell for months while still giving precise, calibrated measurements. The Configurable Logic Cell (CLC) plus CWG allow hardware-only stimulation waveform generation for TENS-style therapy, removing CPU loading from real-time critical paths.
おすすめ
RF-Controlled Toy and Consumer Device
Low-cost, RF-controlled toys, remote controls and consumer appliances that demand low standby consumption find the PIC16F19175T-I/PT a cost-effective main controller. The CWG and 16-bit PWM drive toy-grade BLDC and brushed motors precisely; XLP Sleep keeps current draw below 1 uA for shelf-life. The internal 32 MHz oscillator plus internal pull-ups reduce external components and PCB area dramatically, simplifying layout for small-form-factor designs. The integrated charge-pump LCD drive supports multi-segment low-cost displays.

設計ノート
Estimated: at 32 MHz with 3.3 V VDD the active current is approximately 4-5 mA per the Microchip datasheet typical curves; Sleep with LCD charge pump off drops below 1 uA. For battery life estimates, assume duty cycle = (Tsample / (Tsample + Tsleep)) and use Sleep current plus active burst current directly. Designers targeting 5+ year battery life on a CR2032 should keep average duty cycle under 0.1%.
Use a solid ground plane directly under the device with VDD decoupling split between a 100 nF ceramic at VDD/AVDD pins and a bulk 4.7-10 uF tantalum or ceramic on the same rail. Place the ICSP/PGD/PGC traces away from analog signals and keep them as short as possible to avoid in-circuit debug noise coupling into ADC channels. The charge-pump pins VLCD1-VLCD3 require external capacitors 1uF-X7R; place them within 5 mm of the pins to avoid display flicker.
When migrating firmware from PIC16F188xx to PIC16F19175, the memory map is different and Config Word registers are not bit-compatible. Always recompile with the matching device header file in MPLAB X. Also note that the -I/PT suffix specifies industrial temperature and tape-and-reel - parts in tubes are -I/P (PDIP) or -I/PV (QFN). Mixing packages or grades can cause -I tape-reel SIL at the pick-and-place line.
For designs routing PWM or CWG outputs to drivers, series-terminate traces at the source when edges exceed 5 MHz to prevent ringing. The 5-bit DAC output buffer must be buffered by an external op-amp if the load is below 5 kohm, or it will degrade linearity.
コンプライアンス情報
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified (PIC16F19175T-I/PT is industrial grade); the PIC16F19175-E/PT is also not AEC-Q100 qualified (extended temperature only). For automotive designs requiring AEC-Q100, use the PIC16F15376-I/PT from Microchip's automotive 8-bit portfolio.
