**82C735 I/O Peripheral Controller With Printgine c:Jul93
***Info:
The CHIPS 82C735 enhanced I/O peripheral controller is a single-chip
solution offering complete I/O capabilities for PC/AT and PC/XT
motherboard applications. The controller is configured via
software. The 82C735 features a floppy disk controller, a digital data
separator, two 16550 compatible UARTs, an enhanced bidirectional
parallel port interface called Printgine, IDE interface control logic,
and a game port chip select. For more information about these
systems, see the Functional Description [see datasheet].
4MB FLOPPY DISK CONTROLLER
The floppy disk controller is software compatible with 765B and 82077
controller functions. It provides a 4MB perpendicular recording format
as well as the standard floppy drive format for 5.25-inch and 3.5-inch
media. The controller supports two drives directly and up to four
drives with an external decoder.
DIGITAL DATA SEPARATOR
The digital data separator is capable of data transfer rates up to
1MB/sec and requires no external components.
NS16550 UARTS AND IDE
The two licensed NS16550 UARTs are improved versions of the NS16450
UARTs. They are provided with individual 16-byte FIFOs to relieve the
CPU of excessive software overhead and are still capable of running
existing 16450 software.
The IDE control logic provides a complete IDE interface for embedded
hard disk drives.
MOUSE PORT LOGIC
The 82C735 controller features optional PS/2 style mouse port logic
with BIOS and driver support. Only one of the UARTs can be used when
the mouse is operational.
PRINTGINE PARALLEL PORT INTERFACE
The parallel port interface, Printgine, is a multiprotocol interface
capable of supporting both unidirectional and bidirectional transfer
modes. It is fully compatible with ISA and PS/2 in the standard modes,
and also supports Microsoft ECP, EPP, and fast Centronics in the
enhanced modes. The output on the control pins switch to become
bidirectional TTL drivers in the fast modes. This makes the port run
faster than is possible with the open-drain drivers provided for the
standard modes.
Printgine provides an economical mechanism for significantly improving
the throughput of an improved parallel port that is upward compatible
with the existing parallel port. The interface can operate in five
different modes: standard (ISA-style unidirectional), bi-di
(PS/2-style bidirectional), Microsoft ECP, EPP, and fast
Centronics. The standard and bi-di modes are compatible with existing
parallel port protocols.
The ECP, EPP, and fast Centronics protocols are enhanced bidirectional
modes that achieve dramatic improvement by implementing the protocols
in hardware. The fast Centronics mode is capable of a data transfer
rate of 200KB/sec, while the ECP and EPP modes are capable of data
transfer rates of 2MB/sec, compared to 15KB/sec in the standard mode.
POWER MANAGEMENT
The 82C735 is provided with several power management features that are
controllable through hardware or software. In hardware, the device
can be completely powered down through a powerdown pin. In this mode,
all inputs are disabled, all outputs are inactive, and the contents of
all registers are preserved (as long as the power supply is
maintained). In software, the device allows each port to be powered
down independently.
