PIC18F25K22-I/SS Device Overview

● New Core Features

Technology XLP The PIC18(L)F2X/4XK22 series of products includes several features that can dramatically lower operating power consumption. Important items include:

Other Run Modes: Power consumption during code execution can be lowered by up to 90% by timing the controller from the Timer1 source or the internal oscillator block.

● Multiple Idle Modes:

The controller can also function with the CPU core turned off but the peripherals activated. In these conditions, power consumption can be cut to as little as 4% of what is needed for typical operation.

● On-the-fly Mode Switching:

The power-controlled modes are activated by user code while the system is running, allowing users to build power-saving features into the software architecture of their applications.

● Low Consumption in Key Modules:

Both Timer1 and the Watchdog Timer use the least amount of power possible.

Detailed Description

The oscillator module’s flexible clock sources and selection options make it suitable for a wide range of applications, and it does so while maintaining high performance and low power consumption.

There are several different clock sources that can be set up, including external oscillators, quartz crystal resonators, ceramic resonators, and Resistor-Capacitor (RC) circuits. Furthermore, software allows you to choose from three different internal oscillators, each of which can serve as the system clock. The software lets users choose between an external source and the system clock.

Two-Speed Start-up mode reduces the time for an external oscillator to begin running code. A Fail-Safe Clock Monitor (FSCM) will immediately switch to the internal oscillator if the external clock source (LP, HS,  XT, EC, or RC modes) fails. The Oscillator Start-up Timer (OST) maintains a reliable crystal oscillator source.

External Clock Modes

● Oscillator Start-Up Timer (OST)

A total of 1024 oscillations from OSC1 are counted by the Oscillator Start-up Timer (OST) when the oscillator module is set to LP, XT, or HS modes. This happens after a POR, the Power-up Timer (PWRT) has elapsed (if set) or after waking up from Slumber. The program counter stops increasing; no further processing occurs during this period. The OST verifies that the quartz crystal resonator or ceramic resonator-based oscillator circuit has started up and supplies a stable system clock to the oscillator module. A transition time is needed when changing clock sources to stabilize the new clock.

● PLL Frequency Multiplier

For those who prefer a lower oscillator frequency or who want to clock the device up to its maximum rated frequency from the crystal oscillator, a Phase-Locked Loop (PLL) circuit is included as an optional extra. Customers who worry about electromagnetic interference (EMI) from high-frequency crystals and users who need faster clock rates from an internal oscillator may find this handy.

● PLL In External Oscillator Modes

By changing the PLLCFG bit (CONFIG1H) or the PLLEN bit (CONFIG1L), the PLL can be activated for any of the external oscillator modes utilizing the OSC1/OSC2 pins (OSCTUNE). The PLL can accept input frequencies between 4 MHz and 16 MHz. Then, the PLL multiplies the oscillator output frequency by four to generate an internal clock frequency of up to 64 MHz. Using an oscillator with a frequency lower than 4 MHz with the PLL is prohibited.

● PLL IN HFINTOSC MODES

By combining the internal oscillator block with the 4x frequency multiplier, higher device clock speeds can be achieved than would otherwise be achievable. When activated, the PLL may generate clock speeds of up to 64 MHz by multiplying the HFINTOSC by a factor of four. Using an internal clock mode, the PLL is completely out of the user’s hands and can only be managed programmatically, unlike when using an external clock mode. When using the HFINTOSC, the PLL operation can be enabled or disabled via the PLLEN control bit of the OSCTUNE register. The PLL supports input frequencies between 4 MHz and 16 MHz.
