**M1489/87 FinALi-486 PCI Chipset <Feb95
***Info:
ALi's M1489/M1487 PCI chipset is the most cost effective PCI solution
available. M1489/M1487 enables top-to-bottom PCI in 486 CPU systems,
offering superior price/performance for mainstream PCI-ISA systems.
M1489/M1487 highly integrates the DRAM controller, L2 cache control-
ler, Host, PCI, and ISA interface, as well as the standard ISA
functions: DMA controller, interrupt controller, timer/counter, RTC
(Real Time Clock), and keyboard controller. Additionally, M1489/M1487
incorporates the high performance Local Bus IDE allowing a system de-
signer to implement Local bus IDE with no additional cost. M1489/M1487
is a highly integrated solution requiring minimized TTL components,
enabling PCI-ISA designs at costs equal to or lower than comparable VL
Bus designs.
M1489 (Cache Memory PCI Controller: CMP) integrates the L2 cache con-
troller and the DRAM controller. The cache controller supports
write-back cache policies and cache size from 128K to 1M byte in an
interleaved or non-interleaved configuration. The DRAM controller
interfaces DRAM to the Host bus, PCI bus, and Link bus. M1489 can
support EDO 3/5V DRAM, standard DRAM, and flexible timing
select. M1489 also integrates intelligent Host to PCI, PCI to Host
buffer to achieve high performance. Also, M1489 provides the high
performance Local Bus IDE interface.
M1487 (ISA Bridge Controller: IBC) provides the bridge between the ISA
bus, PCI bus, and Host bus. IBC integrates the common I/O functions
found in today's ISA based systems: a seven channel DMA, two 82C59
interrupt controllers, 8254 timer/ counter, deep green function, and
control logic for NMI generation. IBC also has built-in 128 bytes RTC,
MC14069, KBC, and 7406. IBC also provides the decode for external
BIOS.
