MICROCHIP PIC18F6622 8-bit Flash Microcontroller, 64kB, TQFP64

The MICROCHIP PIC18F6622-I/PT is an enhanced flash microcontroller featuring advanced 10-bit analogue-to-digital conversion and sophisticated nanoWatt power management technology. It is engineered for demanding low-power and connected applications, offering robust connectivity through four serial ports—two synchronous (supporting I²C™ and SPI™ protocols) and two asynchronous (LIN capable). Its substantial RAM and 64kB flash program memory provide ample space for data buffering and complex code, making it exceptionally suitable for instrumentation panels, TCP/IP enabled embedded systems, and industrial control and monitoring solutions.

This microcontroller excels in power efficiency with multiple operational modes: Run, Idle, and Sleep. Its flexible oscillator structure supports four crystal modes with frequencies up to 40MHz, plus an internal oscillator block for design versatility. For reliable system operation, it includes three programmable external interrupts, four input change interrupts, and an extended watchdog timer (WDT). Data integrity is assured with typical flash and EEPROM retention of 100 years.

Key features include self-programmability under software control, priority levels for interrupts, and a single 5V supply requirement. It supports In-Circuit Serial Programming™ (ICSP™) and In-Circuit Debug (ICD) via just two pins each, significantly simplifying the development and programming process. The device comes in a compact TQFP64 surface-mount package, designed for high-density PCB layouts.
