Microchip Technology, Inc. Microcontrollers PIC16F628-20I/SO

The PIC16F628-20I/SO is an 8-bit FLASH-based microcontroller from Quarktwin Technology Ltd. It features a high-performance RISC CPU with a maximum operating speed of 20 MHz and a 200 ns instruction cycle. The device includes 2048 x 14 bits of program memory, 224 x 8 bits of RAM, and 128 x 8 bits of EEPROM. This microcontroller supports a variety of peripheral features, including 16 I/O pins with individual direction control, multiple timers (Timer0, Timer1, and Timer2), and a Capture, Compare, PWM (CCP) module. It also incorporates an analog comparator module with programmable voltage reference and input multiplexing capabilities. Special features include power-on reset, brown-out detection, a watchdog timer, and in-circuit serial programming. The operating voltage range is from 3.0V to 5.5V, with low power consumption characteristics, making it suitable for battery-operated applications. The device is available in an 18-pin SOIC package, which is ideal for space-constrained designs.
