Microchip PIC18F6622 8-bit Flash Microcontroller 64kB TQFP64

Microchip PIC18F6622 8-bit Flash Microcontroller with 64kB flash program memory offers advanced 10-bit analogue-to-digital conversion and nanoWatt power management technology for low-power and connected applications.

Overview

The PIC18F6622 is an enhanced flash microcontroller with 3.84kB RAM, providing space for data buffering and complex code. It features a 12-channel, 10-bit ADC and supports four serial ports: two synchronous ports supporting I²C and SPI protocols, and two asynchronous ports that are LIN capable. Its flexible oscillator structure supports four crystal modes with frequencies up to 40 MHz, plus an internal oscillator block for design versatility.

Key Features

• Run, Idle and Sleep operating modes for efficient power use
• Three programmable external interrupts and four input change interrupts
• Extended watchdog timer (WDT) for reliable system operation
• Self-programmability under software control and priority levels for interrupts
• Single 5V supply requirement with an operating voltage of 4.2V to 5.5V
• In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD), each via two pins
• Typical flash and EEPROM data retention of 100 years
