PIC16F883-E/SP - 20MHz 8-Bit PIC Microcontroller | Microchip
MPN： PIC16F883-E/SP ✓ 啟用中PIC16F883-E/SP 概覽
A PIC microcontroller is a programmable integrated circuit designed around a compact reduced-instruction-set-computing architecture. The PIC16F883 belongs to the PIC16 family of 8-bit microcontrollers, combining embedded CPU core, Flash program memory, data RAM, EEPROM, timers, serial interfaces, and digital I/O in one device. This integration allows a control system to execute firmware while reading sensors, driving outputs, and communicating with external equipment.
The device provides 4K words of program memory, 256 bytes of data RAM, and 256 bytes of EEPROM according to the Microchip product page. Its 35 single-word instruction set simplifies code development, while the 25 available I/O pins provide flexible connections for switches, indicators, actuators, and serial interfaces. The -E/SP ordering identifies the extended-temperature device supplied in a 28-pin SPDIP package.
The PIC16F883 architecture combines a Flash-based program memory with self-programming capability. Its 8-bit CPU can operate at up to 20 MHz, allowing developers to balance processing speed against clock, power, and timing requirements. Because the same controller family supports application-specific firmware, the device can serve both simple state machines and more structured embedded-control designs.
Typical uses include industrial control panels, building equipment, appliance controllers, instrumentation, and compact embedded systems. The 25 I/O pins are useful for reading discrete inputs and controlling relays, indicators, sensors, or peripheral interfaces. Its EEPROM can retain configuration and calibration values, while self-programming supports firmware updates in deployed equipment when the application includes suitable update logic.
When designing a PCB around the PIC16F883-E/SP, reserve all 28 package positions, verify oscillator and decoupling connections against the manufacturer datasheet, and account for the larger footprint of the SPDIP package. Use the configuration words and programming documentation to select the clock, reset behavior, watchdog settings, and brown-out behavior required by the final product.
This product page combines the official device specifications, a documented pin-compatible industrial-temperature option, application guidance, and practical design notes. It is structured to help engineers determine whether the 28-pin PIC16F883-E/SP fits the required memory, I/O, timing, temperature, and packaging constraints before beginning PCB implementation.

典型應用
PIC16F883-E/SP 適用於 6 應用s: Industrial Control Panels, Appliance and Equipment Controllers, Building and HVAC Equipment, Instrumentation and Data Acquisition, LED Lighting and Display Control, Embedded Sensors and IoT Gateways.
Industrial Control Panels
PIC16F883-E/SP fits compact machine-control panels that need a 20 MHz 8-bit processor, 25 I/O pins, and retained configuration data in a 28-pin DIP footprint. The controller can scan switches and sensors, operate timers, control indicator outputs, and manage communications through its available peripherals. Its 256 bytes of EEPROM are valuable for storing calibration values, device addresses, and operating settings. The PIC16F883-I/SP offers a pin-compatible alternative when its industrial temperature limits better match the installation environment.
推薦
Appliance and Equipment Controllers
PIC16F883-E/SP is well suited to appliances and small equipment that combine local decision-making with stored operating profiles. Its 20 MHz CPU provides useful timing margin for motor-stepping, display updates, button handling, and supervisory control, while 25 I/O pins distribute connections across sensors and actuators. The self-programmable Flash memory supports application-managed firmware revisions, and the 256-byte EEPROM preserves calibration or setup information across power cycles without adding an external memory device.
推薦
Building and HVAC Equipment
PIC16F883-E/SP can serve as the local controller in a small HVAC, environmental-monitoring, or building-equipment module. The 25 available I/O pins can accommodate digital inputs, alarm outputs, status indicators, and interface signals, while the 7 KB Flash program area accommodates a structured control program and configuration tables. EEPROM preserves operating schedules, calibration coefficients, and equipment identifiers. In deployed equipment, self-programming can support controlled firmware maintenance when the design includes power-failure protection and update validation.
推薦
Instrumentation and Data Acquisition
PIC16F883-E/SP is appropriate for compact instrumentation that coordinates sensor selection, digital status lines, local displays, and a communications interface. The 20 MHz CPU permits responsive sampling and control loops, while 256 bytes of RAM and 256 bytes of EEPROM divide working storage from retained calibration data. A designer can use the 25 I/O pins for discrete sensor channels and control outputs, then add a suitable communications peripheral for host reporting. The same architecture also supports metering and maintenance records that must survive power removal.
推薦
LED Lighting and Display Control
PIC16F883-E/SP can manage compact LED lighting systems, status panels, and sequenced display products where a dedicated display controller is unnecessary. Its 25 I/O pins provide parallel connections for indicator levels, buttons, and external driver-control signals, while the 20 MHz CPU can execute timing, dimming, fault detection, and user-interface logic. EEPROM can retain brightness presets, operating schedules, or counter values. The 28-pin SPDIP package also supports prototype and repair workflows where through-hole assembly is preferred.
推薦
Embedded Sensors and IoT Gateways
PIC16F883-E/SP works as a low-cost edge controller for compact IoT sensor nodes that need local logic, nonvolatile configuration, and multiple digital connections. The 8-bit architecture can filter inputs, manage thresholds, and coordinate low-power sensor operation at up to 20 MHz. Its 256-byte EEPROM can store node identity and calibration data, while self-programming offers a path to application-managed firmware updates. The 25 I/O pins are useful in gateway products that aggregate several discrete sensor inputs before passing information to a higher-level communications controller.

設計說明
Assign every one of the 28 SPDIP positions using the manufacturer pin-description table for the 28-pin PIC16F883 device. Place programming-access and reset-related connections where service technicians can reach them without removing the controller. Keep the footprint mechanically centered on a 0.1-inch grid and verify that adjacent traces can accommodate the IC’s temperature and soldering requirements.
Design the supply and decoupling around the exact electrical limits in data sheet 41291F, including operating voltage, current, and power conditions. Add the required bypass capacitor close to the supply pins with a short return path to the ground reference. If the selected clock source, output pins, or load current increases dissipation, recalculate junction temperature rather than assuming the controller remains cool in its SPDIP package.
Do not substitute the -E and -I ordering codes without checking the operating-temperature limits. Both devices use the same 28-pin SPDIP format and core resources, but the grade designation affects environmental suitability. Also confirm the oscillator configuration, configuration words, brown-out behavior, watchdog setting, and programming method against the family data sheet before releasing production firmware.
Separate sensitive measurement or communication paths from switching and high-current traces even when the target is a general-purpose controller. Use a compact ground return beneath the device, avoid routing clock signals beside noisy outputs, and keep programming and reset nodes away from long unprotected traces. These practices improve signal integrity in compact industrial-control and instrumentation layouts.
