PIC16F777-E/P - 20MHz 8-Bit Flash MCU | Microchip Technology
部品番号: PIC16F777-E/P ✓ 生産中PIC16F777-E/P 概要
A PIC microcontroller is a compact embedded-control IC combining a processor core, program memory, data memory, I/O ports, and dedicated peripherals on one integrated circuit. PIC16F777 belongs to the PIC16 family of 8-bit RISC devices. Within the embedded-control hierarchy, it is a flash-programmable microcontroller with analog measurement and serial-communication capabilities rather than a general-purpose processor or a standalone analog component.
The verified device information identifies 14 KB of Flash memory, a 20 MHz operating frequency, and 5 V operation. Its 14-channel, 10-bit ADC supports quantized analog measurements, while three timers and three Capture/Compare/PWM functions provide timing, edge capture, comparison, and pulse-width-modulation resources. The synchronous serial port supports either three-wire SPI or two-wire I2C operation, and a USART provides asynchronous serial communication.
The PIC16F777-E/P uses a RISC-based 8-bit architecture and combines 36 I/O lines with multiple communication peripherals. Its 40-pin PDIP package exposes the analog, digital, power, programming, and clock-related connections through a through-hole footprint. Because the verified data does not provide complete register definitions, electrical limits, or a full pin table, those details should be confirmed against the manufacturer documentation before final schematic or firmware sign-off.
Typical uses include industrial control and automation, instrumentation with analog sensing, communications equipment, and general embedded products. The ADC supports sensor-oriented designs, the timers and PWM functions assist actuator and motor-control tasks, and SPI, I2C, and USART permit connection to displays, transceivers, memory devices, and other controllers. The -E/P order code denotes the supplied package and temperature-grade configuration.
Designers should reserve the programming and debug connections required by the PIC16F777 family and verify signal levels, peripheral multiplexing, and analog-channel availability in the manufacturer pin and electrical documentation. Software should account for the shared I/O resources and configured peripheral functions. Because the supplied snippets do not confirm full operating-temperature limits or absolute maximum ratings, those values must not be inferred from the E designation alone.
This page consolidates verified manufacturer features, distributor availability references, package information, and selection guidance. It also distinguishes the confirmed PIC16F777-E/P data from missing electrical, pinout, pricing, and lifecycle details, helping engineers identify what must still be checked in the official datasheet before design release.

主な用途
PIC16F777-E/P の用途: 6 件s: Industrial Control and Automation, Analog Sensor Instrumentation, Motor and PWM Control, Communications Equipment, Data Logging and Acquisition, Consumer and Embedded Products.
Industrial Control and Automation
PIC16F777-E/P fits industrial control boards that require both analog measurement and multiple digital interfaces. Its 8-bit core and 14 KB of Flash provide room for a control application, while 36 I/O lines support switches, indicators, actuators, and field inputs. The 14-channel, 10-bit ADC can monitor pressure, temperature, level, or process-potential signals after suitable conditioning, and the three timers plus three Capture/Compare/PWM functions support periodic sampling and actuator modulation. SPI, I2C, and USART permit expansion through sensor hubs, isolated serial links, displays, or remote I/O. For deployment, designers should confirm analog input limits, peripheral pin multiplexing, and environmental grade in the manufacturer datasheet before releasing the control board.
おすすめ
Analog Sensor Instrumentation
PIC16F777-E/P is appropriate for compact instrumentation that converts several analog inputs into processed measurements and control outputs. The integrated 14-channel, 10-bit ADC permits multiplexing across multiple sensor channels, while three timers can establish sampling intervals or time external events. With 14 KB of Flash and 36 I/O, the device can combine measurement logic, local filtering, status reporting, and operator-interface control without requiring a separate processor. The synchronous serial port can use SPI or I2C to connect to a display, external converter, or sensor interface, while USART supports a communications link. The application should use conditioned inputs, verify the acquisition and noise characteristics from the datasheet, and account for the limited ADC resolution when selecting sensor and amplifier circuits.
おすすめ
Motor and PWM Control
PIC16F777-E/P can serve as the timing and control core for low- to medium-complexity motor and valve-control systems. Three dedicated timers provide the basis for counting, periodic control, and timing functions, while three Capture/Compare/PWM modules can generate modulation outputs where their pins and alternate functions permit. The MCU's 36 I/O lines allow direct connections to position sensors, limit switches, gate drivers, and status LEDs, and the 10-bit ADC can monitor current or position feedback after suitable scaling. A designer can use the USART for a host or module connection and SPI or I2C for additional controllers. Before using it in a safety- or power-stage design, verify PWM frequency, timer resolution, pin assignments, and thermal conditions in the official documentation.
おすすめ
Communications Equipment
PIC16F777-E/P is suitable for embedded communications equipment that must combine protocol handling with local control and analog supervision. Its synchronous serial port supports either three-wire SPI or two-wire I2C, enabling connections to transceivers, memories, codecs, and display controllers, while the USART supports asynchronous links to modules or service equipment. The 8-bit processor and 14 KB of Flash can manage lightweight protocol stacks, configuration, status reporting, and front-panel behavior. Thirty-six I/O lines provide flexibility for indicators, configuration switches, and supervisory signals, and the ADC can monitor supply or analog status when required. Firmware must manage the shared peripheral pins carefully, and any communications timing, logic-level, and isolation requirements should be verified against the selected external interface components.
おすすめ
Data Logging and Acquisition
PIC16F777-E/P can form the acquisition core of a compact data-logging or condition-monitoring device. The 14-channel, 10-bit ADC allows multiple analog variables to be sampled, while three timers establish regular acquisition intervals or measure pulse widths through Capture/Compare functions. Its 14 KB Flash stores the operating program and configuration logic, and the 36 I/O lines can support sensors, status indicators, and local controls. SPI or I2C can connect to external nonvolatile storage or a host controller, while USART offers a simpler serial export path. The design should establish whether 10-bit resolution meets the measurement objective, define averaging and calibration behavior in firmware, and confirm ADC acquisition, input, and timing parameters in the manufacturer datasheet.
おすすめ
Consumer and Embedded Products
PIC16F777-E/P can serve as the central controller in a cost-conscious embedded product combining digital I/O, analog monitoring, and serial connectivity. Its 8-bit RISC architecture and 14 KB of Flash are suited to appliance controls, small test products, interface modules, and accessory controllers. The 36 available I/O lines can operate indicators, keys, relays, or sensors, while the 14 ADC channels support analog control inputs. Three timers and three PWM functions add flexible timing, and SPI, I2C, and USART options allow the controller to work with displays, memory, wireless modules, or other embedded subsystems. Because the verified material does not provide the full pin map or operating limits, the schematic must be checked against the official 40-pin PDIP documentation and the production design must confirm the appropriate temperature grade.

設計ノート
Assign the 40-pin PDIP connections directly from the official PIC16F777 pin table and verify every alternate-function multiplexing choice. The verified data confirms 36 I/O lines, 14 ADC channels, SPI/I2C, USART, three timers, and three CCP functions, but it does not provide the complete numbered pin map. Before laying out a PCB, reserve the device programming connections, identify which ADC channels are physically available, and confirm whether any selected peripheral function conflicts with a planned digital signal.
Keep analog and digital return paths disciplined even though the PIC16F777-E/P operates from a verified 5 V supply. Route sensitive sensor inputs away from switching nodes and high-current return paths, use a quiet analog reference where the design requires it, and follow the manufacturer's recommended input-conditioning and decoupling arrangements. The 10-bit ADC resolution does not remove the need for gain, filtering, grounding, and calibration, so validate the complete analog front end rather than treating the MCU ADC as a precision converter by itself.
Do not infer the complete pinout, absolute maximum ratings, operating-temperature range, or programming interface from the distributor snippets. The supplied evidence confirms the major architectural features and the 40-pin PDIP format, but it does not include the manufacturer pin table or full electrical characteristics. Download the current Microchip Technology documentation, check applicable errata, and validate timer, ADC, serial-port, and programming configurations in the actual toolchain before schematic approval.
The verified operating voltage is 5 V, but the supplied material does not state supply-current limits, internal voltage tolerances, or recommended decoupling values. Use the manufacturer power-pin and decoupling guidance rather than generic values, and include local supply bypassing close to the device. If the 5 V rail is shared with motors, relays, LEDs, or other switching loads, use appropriate partitioning so transients do not corrupt ADC measurements or disrupt serial communication.
A shared SPI or I2C connection can introduce pin conflicts because the same physical I/O lines may support multiple peripherals. Establish a firmware-level peripheral allocation plan, define bus addresses and chip selects where applicable, and account for signal direction changes during SPI transfers. The verified product information confirms both SPI and I2C operation but does not specify pin mappings, so those assignments must be taken from the official package data before connecting external devices.
コンプライアンス情報
The supplied verified material does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for PIC16F777-E/P. These fields remain unknown rather than being inferred from the manufacturer or package designation.
