PIC16F1937-I/P - 32MHz 8-Bit MCU | Microchip Technology
MPN: PIC16F1937-I/P ✓ فعالPIC16F1937-I/P نمای کلی
What is an 8-bit microcontroller? An MCU is a programmable integrated circuit containing a CPU, memory, and peripherals on one semiconductor device. A PIC16 MCU combines an 8-bit RISC core with Flash memory and dedicated hardware for sensing, timing, communication, and control. The PIC16F1937 belongs to the PIC16 family and targets compact, low-cost systems that require deterministic peripheral operation without a higher-cost processor.
The device provides 14 KB Flash organized as 8K words, 512 bytes of data RAM, and 256 bytes of EEPROM according to distributor data. Its listed peripherals include a 10-bit ADC with 14 channels, two comparators, a 5-bit DAC, five timers, five PWM channels, I2C, and LCD-related resources. The 40-PDIP format provides ample through-hole access for prototyping and industrial control boards where socketed assembly or reworkability is useful.
Operation is supported from 1.8 V to 5.5 V, while the -I grade is identified by the industrial temperature designation in the part-number system. The PIC16 core can operate up to 32 MHz, making timing-sensitive tasks such as motor control, metering, signal monitoring, and display scanning practical. The LCD driver and comparator resources can reduce the need for external components in instrument and panel applications.
Typical uses include industrial instrumentation, low-power sensing nodes, LCD-based meters, motor or actuator controllers, embedded automation, IoT peripheral controllers, and general-purpose control boards. The MCU is particularly suitable when a compact 8-bit architecture, Flash programmability, EEPROM, and a through-hole package are more valuable than a high-performance application processor.
Designers should verify the exact pin assignments, peripheral multiplexing, oscillator configuration, and electrical limits in the Microchip manufacturer documentation before layout. A decoupling strategy, oscillator layout guidance, programming interface clearance, and adequate operating-voltage margin should be included in the hardware review. Because the verified search data does not provide complete pin-level information or pricing for every quantity tier, missing technical and commercial values are explicitly marked for follow-up rather than inferred.
This product page combines verified distributor specifications, manufacturer information, package identity, application context, and replacement analysis. It is intended to help engineers identify whether the PIC16F1937-I/P fits a new embedded design or whether a documented pin-compatible substitute is required.

کاربردهای معمول
PIC16F1937-I/P مناسب است برای 6 کاربردs: Industrial Control Panels, LCD Metering and Instrumentation, Low-Power Sensor Nodes, Motor and Actuator Control, Embedded Automation and Data Acquisition, Educational and Rapid Prototyping.
Industrial Control Panels
The PIC16F1937-I/P fits industrial control-panel designs that need local logic, LCD feedback, analog sensing, and relay or actuator outputs in one package. Its verified 10-bit ADC with 14 channels can monitor sensors, while five timers and five PWM channels support timing and proportional control functions. The 40-pin DIP package also simplifies prototype construction and through-hole servicing. A designer should allocate unused pins for status indicators and communications, verify peripheral multiplexing, and use the manufacturer documentation to confirm the exact pin assignments before releasing the PCB.
پیشنهادی
LCD Metering and Instrumentation
PIC16F1937-I/P is a practical choice for compact meters and panel instruments because it combines an LCD driver with a 10-bit ADC, 512 bytes of RAM, and 14 KB of Flash. The microcontroller can acquire sensor inputs, format values, drive a display, and manage keypad or communication tasks without requiring a separate display controller. Its 1.8 V to 5.5 V range supports both low-voltage and 5 V systems, but LCD bias, contrast, operating voltage, and timing must be checked against the exact display and MCU configuration.
پیشنهادی
Low-Power Sensor Nodes
The PIC16F1937-I/P supports low-power embedded sensing because it belongs to the PIC16 family with nanoWatt XLP technology and provides a 10-bit ADC with 14 channels. A battery-powered node can wake for periodic measurements, use the ADC and comparators to evaluate thresholds, store configuration in EEPROM, and return to a low-power state. The actual battery life depends on the selected sleep mode, oscillator, ADC enable time, interrupt strategy, leakage, and sensor load, none of which can be quantified from the supplied web data.
پیشنهادی
Motor and Actuator Control
PIC16F1937-I/P is suitable for basic motor, valve, pump, or actuator control because the verified feature list includes five timers, five PWM channels, two comparators, and a 10-bit ADC. PWM outputs can generate control signals for external transistor or gate-driver stages, while the comparators can monitor threshold conditions and the ADC can sample speed, position, or current-related signals. The MCU does not replace the power stage or its protection components; verify current limits, timing, fault response, thermal behavior, and pin multiplexing in the system design.
پیشنهادی
Embedded Automation and Data Acquisition
The PIC16F1937-I/P can serve as a compact automation controller for distributed measurement and control tasks. Its 8-bit architecture, 14 KB Flash, EEPROM storage, I2C interface, ADC, and PWM resources are useful for gathering sensor data and coordinating small actuators. The through-hole 40-PDIP package is especially useful where boards are assembled manually or maintained in the field. System designers should reserve programming-test access, define I2C addresses, validate timing margins, and document firmware update procedures before production use.
پیشنهادی
Educational and Rapid Prototyping
The 40-pin DIP package and broad integrated peripheral set make PIC16F1937-I/P suitable for educational prototypes, proof-of-concept boards, and small control experiments. Students or engineers can exercise the PIC16 programming model, ADC acquisition, timer scheduling, PWM generation, EEPROM retention, LCD output, and serial communication without building a large support circuit. Because the supplied verified data does not include the complete pinout, prototype wiring must be checked against the official package documentation before power is applied.

یادداشت‌های طراحی
Plan the 1.8 V to 5.5 V supply range before selecting the MCU power architecture. Use the manufacturer’s recommended decoupling arrangement and keep the analog and digital ground strategy consistent with the selected ADC and communication circuits. The verified data does not provide absolute maximum ratings or recommended capacitor values, so those values must be taken from the official datasheet rather than estimated here.
For the 40-PDIP footprint, preserve the manufacturer’s pin numbering and keep the board edge clear enough for insertion and removal. Provide a defined programming or test access point, maintain generous clearance around exposed through-hole pads, and route sensitive analog inputs away from high-current switching nodes. Confirm the exact package drawing before committing the PCB footprint.
Do not assume that every PIC16F193x suffix is electrically or mechanically interchangeable. The verified data confirms PIC16F1937-I/P as a 40-PDIP device, but it does not provide complete alternative pinouts or ordering details. Verify memory size, voltage range, temperature grade, LCD resources, ADC channels, and package suffix in the manufacturer documentation before making a substitution.
Treat the 10-bit ADC inputs as sensitive analog nets. Route them away from PWM outputs, relay drivers, clock lines, and switching power stages; use a stable reference arrangement and minimize long traces. The device includes comparators and a DAC, which can support local signal conditioning, but the external resistor, filtering, and grounding values must be derived from the actual sensor and system requirements.
The I2C and other serial interfaces require deliberate signal integrity planning, especially when long traces connect the controller to sensors or display peripherals. Keep clocks and data paths short where possible, define pull-up values from the bus voltage and capacitance, and avoid routing communication lines across high-current switching paths. Confirm whether the selected peripheral pins are multiplexed with other functions in the exact package variant.
اطلاعات انطباق
The verified snippets identify an industrial-grade PIC16 MCU and mention lead-free information in a secondary listing, but they do not provide authoritative RoHS, REACH, halogen-free, AEC-Q100, or conflict-minerals declarations. Compliance must be confirmed using the current Microchip product documentation and supplier certificates.
