MICROCHIP PIC16F883 8-Bit Microcontroller, 7KB Flash, SOIC-28

The MICROCHIP PIC16F883-I/SO is a versatile 8-bit CMOS flash-based microcontroller, part of the robust PIC16F88x series. Its architecture combines high performance with extensive peripheral integration, making it a powerful yet flexible choice for a wide array of embedded control applications.

At its core is a high-performance RISC CPU operating at up to 20MHz. The device is equipped with 7KB of flash program memory, 256 bytes of EEPROM data memory, and 256 bytes of RAM. A significant advantage is its self-reprogrammability under software control, allowing for flexible in-field updates. For secure development and debugging, it features In-Circuit Serial Programming (ICSP™) and In-Circuit Debug (ICD) capabilities via two pins.

Onboard Peripherals and Features

The PIC16F883 offers a rich set of integrated peripherals designed to minimise external component requirements. This includes an Enhanced Universal Asynchronous Receiver Transmitter (EUSART) for serial communication, plus a synchronous serial port configurable as either 3-wire SPI or 2-wire I²C. For analogue signal acquisition, it provides 11 channels of a 10-bit Analogue-to-Digital (A/D) converter.

Control and timing functions are well catered for with two capture/compare/PWM modules, one of which is an Enhanced Capture/Compare/PWM (ECCP) module featuring auto-shutdown and PWM steering. Additionally, the device includes two analogue comparators and an extended watchdog timer with its own on-chip RC oscillator for reliable operation. System reliability is further enhanced by features like power-on reset (POR), power-saving sleep mode, and two start-up timers (OST and PWRT) to ensure stable operation during power-up.
