AAEON SBC-590 CPU Board. Full-size | PCI/ISA | Pentium CPU Card with SVGA Simple Type: CPU Board

The SBC-590 is an all-in-one single board Pentium computer with an on-board SVGA controller, with PCI-bus and ISA-bus support . It packs all the functions of an industrial computer with display capabilities on a single full-size card. The SBC-590 is fully PC/AT compatible, so your software will run without modifications. The on-board PCI-bus SVGA controller uses the ALG 2032 chipset with 1 MB shared memory. This chipset, used with the local PCI-bus, enables 32-bit graphic throughput and has a built-in Standard Feature Connector. These features make the SBC-590 particularly suited for graphics intensive applications. Another feature of the SBC-590 is the inclusion of a high speed local bus IDE controller. This controller supports (through ATA PIO) mode 3 and mode 4 hard disks, which enables data transfer rates in excess of 11 MB/sec. Up to four IDE devices can be connected, including large hard disks, CD-ROM drives, tape backup drives or other IDE devices. The built-in enhanced IDE controller provides a 4-layer 32-bit posted write-buffer and a 4-layer 32-bit read prefetch to accomplish the IDE boost in performace improvements. On-board features also include two high-speed RS-232 serial ports with 16C550 UARTs, one bidirectional SPP/EPP/ECP parallel port and a floppy drive controller. In addition to the Pentium's 16 KB of on-chip cache memory, the SBC-590 comes with an extra 256 KB or 512 KB of second level memory on-board. If program execution is halted by a program bug or EMI, the board's 16-stage watchdog timer can automatically reset the CPU or generate an interrupt, provided the watchdog timer has been programmed in advance. This ensures reliability in unmanned or stand-alone systems. The SBC-590 supports 5V EDO DRAM. It also provides four 72-pin SIMM (Single In-line Memory Module) sockets for its on-board system DRAM. These sockets give you the flexibility to configure your system from 1 MB to 128 MB of DRAM using the most economical combination of SIMMs.
