V96SSC HIGH INTEGRATION SYSTEM CONTROLLER For i960(R) Jx/Sx and PowerPC 401TM Gx Processors Glueless interface between Intel(R) i960(R) Jx/Sx series and IBM(R) PowerPC 401TM Gx processors, DRAM arrays, and peripheral devices Local bus speeds up to 33 MHz High performance burst DRAM controller with DRAM page cache management Synchronous/asynchronous serial communications unit Two-channel fly-by DMA controller Support for boot PROM devices System heartbeat and watchdog timers Interrupt control unit Up to five programmable chip select/peripheral device strobe generation Two 32-bit general purpose timers with pulse width modulation capability Supports 32-bit bus masters Supports extended burst transactions, up to 1 Kbyte 16 general-purpose I/Os Supports 3.3 V DRAM modules Industrial temperature range (-40C to +85C) Low-cost 100-pin EIAJ PQFP package The V96SSC High Integration System Controller simplifies the design of systems based on Intel's i960(R) Jx/SX and IBM's PowerPC 401TM Gx microprocessors. By using the V96SSC, designers can replace many lower-integration support components with a single, high-integration device--this saves design time, board area, and manufacturing cost. The integrated DRAM controller directly connects the supported i960(R)/PowerPC 401TM processor to DRAM arrays ranging from 128 Kbyte to 128 Mbyte. The fully programmable DRAM controller allows use of a wide range of DRAM speeds and configurations. It supports burst accesses up to 1 Kbyte in length, allowing the use of high-performance, bus-mastering peripherals. The two-channel fly-by DMA controller makes it easy to use less expensive, non-mastering peripherals. To further aid in connecting the processor, the V96SSC's I/O Controller performs address decoding and chip-select/strobe generation. In addition, the I/O lines can be used as simple I/O ports on a bit-by-bit basis. The serial communications unit connects to either RS-232 or synchronous serial devices. The two general-purpose, 32-bit timers can be individually configured as a pulse width modulator or used in other modes, such as retriggering or one-shot. The bus watch timer prevents system hangs during accesses to unpopulated memory. Interrupts for a real-time OS are generated easily by the system heartbeat timer. A watchdog timer is also provided for graceful recovery from catastrophic program failures. Interrupt requests for all on-chip peripherals are managed by the Interrupt Control Unit (ICU). Additionally, off-chip interrupts can be routed via the I/O multiplexer to the ICU. The V96SSC is packaged in a low-cost 100-pin EIAJ Plastic Quad Flat Pack (PQFP), and is available in a 33 MHz speed grade.
