WINBOND I/O
Publication Release Date: April 1998

Version 0.51
GENERAL DESCRIPTION
The W83877ATF is an enhanced version from Winbond's most popular I/O chip W83877F --- which
integrates the disk drive adapter, serial port (UART), IrDA 1.0 SIR, parallel port, configurable plug-
and-play registers for the whole chip --- plus additional powerful features:
IrDA 1.1
(
MIR for 1.152M
bps or FIR for 4M bps
), TV remote IR,
ACPI
, serial IRQ,
full 16-bit address decoding, and ACPI
compliant.
The disk drive adapter functions of W83877ATF include a floppy disk drive controller compatible with
the industry standard 82077/765, data separator, write pre-compensation circuit, decode logic, data
rate selection, clock generator, drive interface control logic, and interrupt and DMA logic. The wide
range of functions integrated onto the W83877ATF greatly reduces the number of components
required for interfacing with floppy disk drives. The W83877ATF supports four 360K, 720K, 1.2M,
1.44M, or 2.88M disk drives and data transfer rates of 250 Kb/S, 300 Kb/S, 500 Kb/S,1 Mb/S, and 2
Mb/S.
The W83877ATF provides two high-speed serial communication ports (UARTs), one of which
supports serial Infrared communication. Each UART includes a 16-byte send/receive FIFO, a
programmable baud rate generator, complete modem control capability, and a processor
interrupt
system. One of the UARTs supporting infrared (IR) includes 32-byte FIFO, serial IR, 1.152M bps MIR,
0.576M bps, 4M bps FIR, and TV remote IR (supporting NEC, RC-5, extended RC-5, and RECS-80
protocols). Both UARTs provide legacy speed with baud rate 115.2k, and provide advanced speed
with baud rate
230k
,
460k
, and
921k bps
which support higher speed Modems.
The W83877ATF supports one PC-compatible printer port (SPP), Bi-directional Printer port (BPP)
and also Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP). Through the printer
port interface pins, also available are: Extension FDD Mode and Extension 2FDD Mode allowing one
or two external floppy disk drives to be connected to the notebook computer.
Winbond W83877ATF provides functions that comply with
ACPI
(
Advanced Configuration and Power
Interface
), which includes support of legacy and ACPI power management through
SMI
or
SCI
function pins. One 24-bit power management timer is implemented with carry notify interrupt.
W83877ATF also has auto power management to reduce power consumption.
The
Serial IRQ
for PCI architecture is supported, ISA IRQs (IRQ1~IRQ15) can be cascaded into one
IRQ pin. W83877ATF also features ISA bus IRQ sharing and allows two or more devices to share the
same IRQ.
W83877ATF is made to fully comply with
Microsoft
TM
PC97 Hardware Design Guide
. IRQs, DMAs,
and I/O space resource are flexible to adjust to meet ISA PnP requirements. Moreover, W83877ATF
is made to meet the specification of PC97's requirement in the power management:
ACPI
and
DPM
(Device Power Management).
The configuration registers support mode selection, function enable/disable, and power down function
selection. Furthermore, the configurable PnP features are compatible with the plug-and-play feature
demand of Windows 95
TM
, which makes system resource allocation more efficient than ever.
Another benifit is that W83877ATF has the same pin assignment as W83877F, W83877AF,
W83877TF. Thius makes the design very flexible.
