PIC18F66K90-I/MR

PIC18F66K90 combines the traditional advantages of all PIC18 microcontrollers – namely, high computational performance and a rich feature set – with a versatile on-chip LCD driver, while maintaining an extremely competitive price point. These features make the PIC18F87K90 family a logical choice for many high-performance applications where price is a primary consideration All of the devices in the PIC18F87K90 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 RC oscillator, power consumption during code execution can be 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 power-managed modes are invoked by user code during operation, allowing the user to incorporate power-saving ideas into their application’s software design. nanoWatt XLP: An extra low-power BOR, RTCC and low-power Watchdog Timer. Also, an ultra low-power regulator for Sleep mode is provided in regulator-enabled modes All of the devices in the PIC18F87K90 family offer different oscillator options, allowing users a range of choices in developing application hardware. These include: External Resistor/Capacitor (RC); RA6 available External Resistor/Capacitor with Clock Out (RCIO) Three External Clock modes: - External Clock (EC); RA6 available - External Clock with Clock Out (ECIO) - External Crystal (XT, HS, LP) A Phase Lock Loop (PLL) frequency multiplier, available to the External Oscillator modes which allows clock speeds of up to 64 MHz.
