PIC18F6722-I/PT

PIC18F6722 offers the advantages of all PIC18 microcontrollers – namely, high computational performance at an economical price – with the addition of highendurance, Enhanced Flash program memory. On top of these features, the PIC18F8722 family introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power sensitive applications. All of the devices in the PIC18F8722 family incorporate a range of features that can significantly reduce power consumption during operation Alternate Run Modes: By clocking the controller from the Timer1 source or the internal oscillator block, power consumption during code execution can be significantly reduced. Multiple Idle Modes: The controller can also run with its CPU core disabled but the peripherals still active. In these states, power consumption can be reduced even further On-the-fly Mode Switching: The powermanaged modes are invoked by user code during operation, allowing the user to incorporate powersaving ideas into their application’s software design. Low Consumption in Key Modules: The power requirements for both Timer1 and the Watchdog Timer are minimized. The PIC18F8722 family provides ample room for application code and includes members with 48, 64, 96 or 128 Kbytes of code space Data RAM and Data EEPROM: The PIC18F8722 family also provides plenty of room for application data. The devices have 3936 bytes of data RAM, as well as 1024 bytes of data EEPROM, for long term retention of nonvolatile data Memory Endurance: The Enhanced Flash cells for both program memory and data EEPROM are rated to last for many thousands of erase/write cycles, up to 100,000 for program memory and 1,000,000 for EEPROM. Data retention without refresh is conservatively estimated to be greater than 40 years
