PIC16F1937-E/PT - 32MHz 14KB LCD MCU | Microchip Technology
MPN: PIC16F1937-E/PT ✓ Hoạt độngPIC16F1937-E/PT Tóm tắt
An 8-bit microcontroller is a programmable semiconductor that integrates a CPU, memory, digital I/O, timers, and peripherals on one chip. PIC microcontrollers extend through the embedded-control hierarchy: MCU, microprocessor, semiconductor, and electronic control component. The PIC16F1937 belongs to Microchip's enhanced mid-range 8-bit family and supports applications that need local display control, serial communication, data storage, and autonomous low-power operation.
Verified distributor information identifies 14KB flash, 512B RAM, 256B EEPROM, an LCD driver, 25 I/O ports, and a 1.8V to 5.5V operating range. Its 32MHz maximum clock supports timing-sensitive control and communication tasks, while nanoWatt XLP technology targets reduced current consumption during inactive operating modes. The -E suffix identifies an extended-temperature grade ordering code, but the exact numerical limits are .
The 44-pin TQFP provides more I/O than smaller packages and supports PCB routing in dense industrial and consumer products. Program memory stores executable firmware, RAM supports working variables, and EEPROM preserves calibration values or configuration data when power is removed. The integrated LCD driver reduces external controller demand in meters, keypads, and compact user-interface products.
Typical applications include utility meters, environmental monitors, industrial panels, sensor interfaces, appliance controls, and handheld instruments. Design teams should verify the complete pin assignment, oscillator options, LCD segment mapping, and peripheral multiplexing in the manufacturer datasheet before routing a PCB. Firmware should also include brownout, watchdog, and reset handling appropriate to the final power-supply design.
This product record combines verified distributor specifications, sourcing links, and application-focused engineering guidance. It does not infer an unverified cross-brand substitute; only explicitly supported same-package alternatives are presented.

Ứng dụng tiêu biểu
PIC16F1937-E/PT phù hợp cho 6 Áp dụngs: Utility Meter with LCD Display, Industrial Control Panel, Environmental Sensor Hub, Battery-Powered Data Logger, Appliance User Interface, Handheld Instrument.
Utility Meter with LCD Display
The PIC16F1937-E/PT fits utility meters because it combines a 32MHz 8-bit CPU, 14KB program flash, 256B EEPROM, and an integrated LCD driver in one 44-pin device. Firmware can acquire measurements from external sensor circuits, maintain operating state in 512B RAM, and retain calibration constants in EEPROM. The 1.8V to 5.5V range supports low-voltage meter designs, while nanoWatt XLP technology can reduce consumption during idle periods. A practical design should map the required LCD segments to the available multiplexed outputs and confirm the display's drive voltage, bias, and common configuration against the Microchip datasheet.
Được đề xuất
Industrial Control Panel
PIC16F1937-E/PT is suitable for compact industrial control panels that combine local LCD feedback, digital inputs, and simple actuator outputs. Its 25 I/O ports provide more interface capacity than smaller MCUs, while 14KB flash accommodates protocol handling, state logic, and panel behavior. The integrated LCD driver allows a keypad-and-display interface without a separate display controller. Because the -E grade is an extended-temperature ordering code, engineers should confirm its exact limits against enclosure temperatures, startup behavior, and regulatory requirements. Galvanic isolation and surge protection must be added where the panel connects to external industrial wiring.
Được đề xuất
Environmental Sensor Hub
The PIC16F1937-E/PT works as a low-power environmental sensor hub for temperature, humidity, air-quality, or light measurements. Its 25 I/O ports can interface with multiple digital sensors, while the integrated LCD driver supports local status display and calibration menus. The 256B EEPROM can retain sensor offsets or configuration values across power cycles, and the 1.8V minimum supply supports battery-oriented designs. Firmware should use the device's low-power modes carefully because display scanning and sensor conversion timing determine the real duty cycle. Sensor accuracy, calibration coefficients, and environmental limits should be validated independently of the MCU specifications.

Battery-Powered Data Logger
PIC16F1937-E/PT can act as the control and logging microcontroller in a battery-powered sensor logger. Its 14KB flash stores firmware, 512B RAM supports transient acquisition state, and 256B EEPROM preserves configuration or small data records. The 1.8V to 5.5V operating range allows integration with low-energy digital sensors, while nanoWatt XLP technology is relevant during idle intervals. Flash endurance and EEPROM write limits must govern the logging strategy; frequently changing records should be buffered in RAM or rotated through external nonvolatile storage. A real-time clock can improve timestamp integrity when each event must remain associated with calendar time.
Được đề xuất
Appliance User Interface
PIC16F1937-E/PT supports appliance interfaces that need a local display, buttons, relays, and status LEDs. Its integrated LCD driver reduces system complexity, and 25 I/O ports leave capacity for human-interface inputs and peripheral control. The 14KB flash capacity can hold a compact menu/state machine, while EEPROM preserves settings such as calibration offsets or operating modes. Designers should use suitable transistor or driver circuits for relays and other inductive loads rather than switching them directly from MCU pins. The 44-pin TQFP footprint is appropriate for leaded-style production assembly, and its 10 x 10mm body supports inspection and rework, but pin density still requires careful fanout on entry-level boards.
Được đề xuất
Handheld Instrument
The PIC16F1937-E/PT is applicable to handheld meters and test instruments that combine an LCD, keypad input, measurement acquisition, and data export. The 32MHz maximum clock supports responsive firmware, while 512B RAM is sufficient for compact working buffers and 256B EEPROM retains user calibration data. Its low-voltage operation can simplify battery-powered designs, and nanoWalt XLP operation is useful when the display or measurement circuitry can remain off between readings. Human-interface and analog accuracy are system-level concerns: use suitable input protection, precision references, and calibration storage. The exact -E temperature limits should be checked against the instrument's intended ambient range.

Ghi chú thiết kế
Design the supply for 1.8V to 5.5V operation and include local bulk and high-frequency decoupling close to the device power pins. The supplied data does not specify the exact VDD and VSS pin numbers, capacitor values, regulator, or startup thresholds, so those values must be taken from the Microchip datasheet. Validate brownout behavior, display-supply sequencing, and sensor load transients before enabling production firmware.
Route the 44-pin TQFP footprint to the package drawing in the current Microchip documentation and preserve pin-1 orientation. Keep analog sensor inputs away from LCD outputs, switching nodes, and high-current return paths. Because exact alternate-function assignments are [DATA_NEEDED: pin-level multiplexing], the schematic and firmware plan must be checked together; a pin may not simultaneously support LCD, digital I/O, and another peripheral.
Do not treat PIC16F1937-I/PT as an unconditional substitute without checking temperature requirements and qualification. The supplied data confirms the same package, clock, flash, RAM, EEPROM, LCD, and voltage range, but it does not provide the numerical limits associated with the -E and -I suffixes. Recompile firmware, verify the programmer target and configuration bits, and review errata before converting an existing production design.
Thông tin tuân thủ
The supplied distributor data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The -E suffix identifies an extended-temperature ordering grade but does not by itself establish AEC-Q100 qualification.
