The V320USC Universal System Controller is a third-generation PCI product which integrates many functions needed in typical embedded systems. The USC reduces overall system cost by replacing a number of lower-integration support components with a single, highly integrated device. The PCI bus is an important standard used in todays embedded systems. While the V320USC addresses this requirement, it is also far more than a simple PCI interface. The USC controls the essential components of an embedded system, such as SDRAM memory, FLASH memory, and peripherals by using a flexible memory controller and peripheral control unit. As a system controller, the V320USC provides additional peripheral functions required in a typical embedded system. Two 32-bit general purpose timers can be individually configured as a pulse width modulator, rate generator, pulse counter, or hardwaresoftware triggered pulse generator Watchdog timer for graceful recovery from catastrophic program failures Heartbeat interrupt timer for RTOS interrupt generation Bus watch timer to prevent system hangs during accesses to undecoded regions Four-channel interrupt controller to generate either PCI or local CPU interrupts and interrupt cross-routing.
