MICROCHIP PIC16F630 8-bit Flash Microcontroller, SOIC-14

The MICROCHIP PIC16F630-I/SL is a versatile 8-bit Flash-based CMOS microcontroller, engineered for reliability in demanding embedded applications. It features a robust 1.75KB of program memory, 128 bytes of EEPROM data memory, and 64 bytes of RAM. An integrated watchdog timer, controlled by configuration bits, enhances system stability by resetting the device in the event of a software malfunction.

A key reliability feature is the on-chip RC oscillator, which allows the microcontroller to run independently, reducing component count. The device includes multiple timers for stable operation: an Oscillator Start-up Timer (OST) ensures the chip remains in reset until the crystal oscillator is stable, while a Power-up Timer (PWRT) provides a fixed 72ms nominal delay on power-up, allowing the supply to stabilise. Combined with brown-out reset circuitry, these integrated functions often eliminate the need for external reset components, simplifying circuit design.

Core Features

• Programmable Options: Includes individual programmable weak pull-up resistors on I/O pins, programmable code protection for intellectual property security, and eight oscillator selections, including a 4MHz RC oscillator with programmable calibration.
• Power Management: Features a power-saving sleep mode to minimise energy consumption in battery-operated or low-power applications.
• Development Support: Offers MPLAB® ICD-2 programming and debugging support with an optional header adapter, facilitating streamlined development and in-circuit debugging.
• High Endurance Memory: Built with high endurance Flash and EEPROM cells for reliable, long-term data storage and firmware updates.

With its compact SOIC-14 surface-mount package, 12 configurable I/O lines, and a wide operating voltage range from 2V to 5.5V, this microcontroller is a flexible solution for a broad spectrum of electronic designs. Its industrial (-
