It has 4 Kx 14-bit words of program memory, 128-byte RAM, 128-bits of EEPROM, and operating voltages up to 5.5V. This microcontroller also provides advanced clock setting for accurate timing and instrumentation.

Features of PIC16C622T-20/SS

The following features of PIC16C622T-20/SS are designed for automotive and industrial applications:

• Power On Reset (POR) - This feature ensures that the microcontroller will reset itself in the event of a power failure or spike.
• Watchdog Timer (WDT) - This feature detects and prevents program execution failure due to unexpected and continuous reset cycles of the MCU.
• Program Memory - This provides up to 4 Kx 14-bit words of program memory that is used by the microcontroller to store the instructions and data.
• RAM - This feature provides 128 bytes of RAM that is used by the microcontroller to store data used during program execution.
• EEPROM - This feature provides 128-bit EEPROM that can be used to store non-volatile data.
• Operating voltage - This microcontroller can operate from 3V to 5.5V.
• Clock Setting - This feature provides precise timing and instrumentation with advanced clock setting.

Working Principle of PIC16C622T-20/SS

The PIC16C622T-20/SS microcontroller works by executing the instructions stored in its program memory. These instructions are then performed by a single instruction cycle, from fetching the instruction from the memory, decoding it, and executing it. It is also capable of performing arithmetic and logic operations, as well as controlling the peripheral devices connected to it.

The PIC16C622T-20/SS microcontroller has a power-on reset (POR) circuit which ensures that when the power is supplied, the microcontroller resets itself and starts executing its boot program. The bootstrap program is stored in the program memory and begins as soon as the power is applied to the microcontroller. Once the bootstrap program is executed, it jumps to the main program stored in the program memory and begins executing the instructions contained in it.

The PIC16C622T-20/SS microcontroller also has a watchdog timer (WDT) circuit which detects and prevents program execution failure due to unexpected and continuous reset cycles. This feature is enabled by a separate instruction and is triggered by a watchdog timer interrupt signal. When triggered, the WDT resets the microcontroller and jumps back to the beginning of the main program again.

The microcontroller also has a power saving feature which allows it to enter different power-down modes when the user application is idle. In these modes, the microcontroller uses less power consumption, but it is still able to wake up to execute the instructions when needed.

The PIC16C622T-20/SS microcontroller also has advanced clock setting features which provide precise timing and instrumentation. This feature enables the microcontroller to execute instructions accurately and swiftly.
