PIC16F883-I/SP - 8-Bit 20MHz Flash MCU | Microchip Technology
The Microchip Technology PIC16F883-I/SP is an 8-bit CMOS flash-based PIC microcontroller operating up to 20MHz, with 7KB of program Flash organized as 4K x 14 words, 256 bytes of RAM, and 256 bytes of EEPROM in a 28-pin SPDIP package. It combines a compact RISC-style architecture with 35 single-word instructions, self-programming, in-circuit debugging support, two comparators, and up to 25 I/O pins.
A PIC microcontroller is an embedded processing semiconductor that integrates a CPU core, nonvolatile program memory, data memory, I/O ports, timers, analog functions, and communication peripherals into one device. PIC16F883 belongs to the 8-bit PIC16 family and sits between basic general-purpose controllers and larger pin-count PIC devices. Its flash-based architecture supports in-system reprogramming, while its EEPROM provides nonvolatile storage for configuration values, calibration data, counters, or serial numbers that must survive a power interruption.
The PIC16F883-I/SP provides 20MHz maximum operation, 7KB of flash program memory, 256 bytes of RAM, 256 bytes of EEPROM, and 25 I/O pins. Self-programming allows firmware to update stored code under defined operating conditions. Integrated in-circuit debugging support simplifies development and troubleshooting, and the two comparators support threshold detection, oscillator monitoring, and basic analog signal conditioning without requiring external comparator ICs.
The device is based on a compact 8-bit PIC architecture with only 35 single-word instructions. This relatively small instruction set can simplify firmware assembly and make instruction timing easier to analyze than with more complex processor cores. Its operating voltage options of 2.5V, 3.3V, and 5V provide flexibility across industrial-control, instrumentation, appliance-control, and embedded accessory designs, although the exact configuration and limits for each voltage must be checked in the manufacturer datasheet.
Typical uses include industrial control panels, motor and relay controllers, temperature-measurement equipment, simple data loggers, interface modules, and compact embedded products. The two comparators are particularly useful in threshold-based sensing systems, while the EEPROM can retain configuration parameters without external nonvolatile memory. The 28-pin SPDIP format also suits prototypes, educational platforms, and designs that require socketed assembly or leaded through-hole construction.
For new production layouts, confirm the exact pin assignment, decoupling requirements, programming method, and peripheral configuration in the PIC16F883 manufacturer documentation. Keep the programming interface and power rails accessible, and apply the manufacturer’s recommended crystal, reset, and decoupling arrangements when reproducing the reference configurations.
