Introduction

The AR-B1476 is a half size industrial grade CPU card that has been designed to withstand continuous operation in harsh environments. The AR-B1476 supports on-board memory 8MB, and extends to 72MB DRAM for using one 72-pin SIMM. The 8 layers PCB CPU card is equipped with an IDE HDD interface, a floppy disk drive adapter, 1 parallel port, 2 serial ports and a watchdog timer. Its dimensions are as compact as 122mmX185mm. It highly condensed features make it an ideal cost/performance solution for high-end commercial and industrial applications where CPU speeding and mean time between failure is critical. The AR-B1476 provides 2 bus interfaces, ISA bus and PC/104 compatible expansion bus. Based on the PC/104 expansion bus, you could easy install thousands of PC/104 module from hundreds venders around the world. You could also directly connect the power supply to the AR-B1476 on-board power connector in standalone applications. A watchdog timer has a software programmable time-out interval, is also provided on this CPU card. It ensures that the system does not hang-up if a program cannot execute normally. The AR-B1476 is implemented with M1487 and M1489 chipset incorporate a memory controller, parity generation and checking, two 8237 DMA controllers, two 8259 interrupt controllers, one 8254 timer/counter, an address buffer and a data buffer. A super I/O chip (SMC37C669) is embedded in the AR-B1476 card. It combines functions of a floppy disk drive adapter, a hard disk drive (IDE) adapter, two serial (with 16C550 UART) adapters and 1 parallel adapter. The I/O port configurations can be done by set the BIOS setup program.
