**M1531/33/43 Aladdin IV & IV+ 50-83.3MHz <05/28/97
***Info:
****M1531 CPU-to-PCI bridge, Memory, Cache and Buffer Controller:
Aladdin-IV is the succeeding generation chipset of Aladdin-III from
Acer Labs. It maintains the best system architecture (2-chip solution)
to achieve the best system performance with the lowest system cost
(TTL free). Aladdin-IV consists of two BGA chips to give the
586-class system a complete solution with most up-to-date features and
architecture for the most engaging multimedia/multithreading OS and
software applications. It utilizes the modern BGA package to improve
the AC characterization, resolves system bottleneck and makes the
system manufacturing easier.
M1531B is the successor of M1531. The major differences are the
64-Mbit SDRAM support and more cacheable region support in SDRAM
configuration. Please refer to the application note in Appendix
A [see datasheet].
M1531B includes the higher CPU bus frequency (up to 83.3MHz) interface
for the incoming Cyrix M2 and AMD K6, PBSRAM and L2 controller,
internal MESI tag bits (8K*2) to reduce cost and enhance performance,
high performance FPM/EDO/SDRAM DRAM controller, PCI 2.1 compliant bus
interface, smart deep buffer design for CPU-to-DRAM, CPU-to-PCI, and
PCI-to-DRAM to achieve the best system performance, and also the
highly efficient PCI fair arbiter. M1531B also provides the most
flexible 32/64-bit memory bus interface for the best DRAM upgrade
ability and ECC/Parity design to enhance the system reliability. With
the concurrent bus design, PCI-to-PCI access can run concurrently with
CPU-to-L2 and CPU-to-DRAM access, PCI-to-DRAM access can run
concurrently with CPU-to-L2 access. M1531B also supports the snoop
ahead feature to achieve the PCI master full bandwidth access
(133Mbytes). M1531B also provides the enhanced power management
features including ACPI support, suspend DRAM refresh, and internal
chip power control to support the Microsoft’s On Now technology OS.
M1533 provides the best power management system solution. M1533
integrates ACPI support, deep green function, 2-channel dedicated
Ultra-33 IDE master controller, 2-port USB controller, SMBus
controller, and PS2 Keyboard/Mouse controller.
M1543 provides the best desktop system solution. M1543 integrates
ACPI support, green function, 2-channel dedicated Ultra-33 IDE Master
controller, 2-port USB controller, SMBus controller, PS/2 Keyboard/
Mouse controller and the Super I/O (Floppy Disk Controller, 2 serial
port/1 parallel port) support.
In the following diagram [see datasheet], ALADDIN-IV gives a highly
integrated system solution and a most up-to-date architecture, which
provides the best cost/performance system solution for Desktop and
also for Notebook vendors.
