W83C553F
General Information
Power Management Break Event support for Green PC applications
Built-in Integrated Peripheral Controller (IPC) with standard PC-AT peripherals
â¢
Two 82C37A DMA controllers (types A, B, and F)
- 32-bit addressing allows use of alternate CPUs, such as PowerPC
- supports multiple 8-bit and 16-bit scatter/gather DMA channels
â¢
Two 82C59A interrupt controllers
- all IRQ inputs may be programmed for edge or level sensitivity
â¢
One 82C54 counter/timer
â¢
Routes external PCI interrupts to a software-selectable interrupt channel
PCI Bus Interface
â¢
PCI Revision 2.1 compliant
â¢
PCI clock frequencies up to 33 MHz at 5V
â¢
Supports delayed completion for ISA cycles
â¢
Active address decoding for internal I/O devices
â¢
Subtractive decoding for ISA bridge, KBC and RTC
â¢
Supports disconnection (with retry) for slow internal accesses to improve latency
â¢
Short PCI bus ownership when mastering to minimize overall system latency
â¢
Fast DMA transfers from I/O devices to PCI agents as a master
â¢
Separate request and grant signals for ISA DMA and IDE controllers
ISA Bus Bridge
â¢
â¢
Full implementation of a standard ISA bus
â¢
Separate ISA and IDE data buses reduce noise and increase system performance
â¢
Synchronous PCI-to-ISA interface with direct drive for 5 ISA slots
XD-Bus interface
â¢
Support for BIOS ROM or PowerPC systems boot ROM
â¢
Support for flash EPROM
â¢
Provides keyboard controller connections
â¢
Provides real-time clock connections
â¢
Provides data buffer control
Miscellaneous
â¢
Port B support
â¢
Port 92 support
Uses 0.6um, ultra-low power CMOS technology for Rev. E and below; 0.5um for Rev. G.
