10 / 446 page PIC18F8722 FAMILY DS39646C-page 8 © 2008 Microchip Technology Inc. Besides its availability as a clock source, the internal oscillator block provides a stable reference source that gives the family additional features for robust operation: • Fail-Safe Clock Monitor: This option constantly monitors the main clock source against a reference signal provided by the internal oscillator. If a clock failure occurs, the controller is switched to the internal oscillator block, allowing for continued low-speed operation or a safe application shutdown. • Two-Speed Start-up: This option allows the internal oscillator to serve as the clock source from Power-on Reset, or wake-up from Sleep mode, until the primary clock source is available. 1.1.4 EXTERNAL MEMORY INTERFACE In the unlikely event that 128 Kbytes of program memory is inadequate for an application, the PIC18F8527/8622/8627/8722 members of the family also implement an external memory interface. This allows the controller’s internal program counter to address a memory space of up to 2 Mbytes, permitting a level of data access that few 8-bit devices can claim. With the addition of new operating modes, the external memory interface offers many new options, including: • Operating the microcontroller entirely from external memory • Using combinations of on-chip and external memory, up to the 2-Mbyte limit • Using external Flash memory for reprogrammable application code or large data tables • Using external RAM devices for storing large amounts of variable data 1.1.5 EASY MIGRATION Regardless of the memory size, all devices share the same rich set of peripherals, allowing for a smooth migration path as applications grow and evolve. The consistent pinout scheme used throughout the entire family also aids in migrating to the next larger device. This is true when moving between the 64-pin members, between the 80-pin members, or even jumping from 64-pin to 80-pin devices. 1.2 Other Special Features • Communications: The PIC18F8722 family incorporates a range of serial communication peripherals, including 2 independent Enhanced USARTs and 2 Master SSP modules capable of both SPI and I2C (Master and Slave) modes of operation. Also, one of the general purpose I/O ports can be reconfigured as an 8-bit Parallel Slave Port for direct processor-to-processor communications. • CCP Modules: All devices in the family incorporate two Capture/Compare/PWM (CCP) modules and three Enhanced CCP (ECCP) modules to maximize flexibility in control applications. Up to four different time bases may be used to perform several different operations at once. Each of the three ECCP modules offer up to four PWM outputs, allowing for a total of 12 PWMs. The ECCPs also offer many beneficial features, including polarity selection, Programmable Dead-Time, Auto-Shutdown and Restart and Half-Bridge and Full-Bridge Output modes. • Self-Programmability: These devices can write to their own program memory spaces under internal software control. By using a bootloader routine located in the protected boot block at the top of program memory, it becomes possible to create an application that can update itself in the field. • Extended Instruction Set: The PIC18F8722 family introduces an optional extension to the PIC18 instruction set, which adds 8 new instruc- tions and an Indexed Addressing mode. This extension, enabled as a device configuration option, has been specifically designed to optimize re-entrant application code originally developed in high-level languages, such as C. • 10-bit A/D Converter: This module incorporates programmable acquisition time, allowing for a channel to be selected and a conversion to be initiated without waiting for a sampling period and thus, reduce code overhead. • Extended Watchdog Timer (WDT): This enhanced version incorporates a 16-bit prescaler, allowing an extended time-out range that is stable across operating voltage and temperature. See Section 28.0 “Electrical Characteristics” for time-out periods. |
