REV. 1.2.0
UNIVERSAL (3.3V AND 5V) PCI BUS DUAL UART
5
NOTE: Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain.
TMRCK
75
I
16-bit timer/counter external clock input.
ENIR
74
I
Global Infrared mode enable (active high). This pin is sampled during power
up, following a hardware reset (RST#) or soft-reset (register RESET). It can
be used to start up both UARTs in the infrared mode. The sampled logic state
is transferred to MCR bit-6 in the UART. Software can override this pin there-
after and enable or disable it.
EN485#
65
I
Global AutoRS485 half-duplex direction control enable (active low). During
power up or reset, this pin is sampled and if it is a logic high, both UARTs are
set for Auto RS485 Mode. Also, the Auto RS485 bit, FCTR[5], is set in both
channels. Software can override this pin thereafter and enable or disable it.
TEST#
79
I
Factory Test. Connect to VCC for normal operation.
VCC
54, 80
PWR
5V or 3.3V power supply for the core logic. This power supply determines
the VOH level of the non-PCI bus interface outputs. Note that VCC
≥ VIO for
normal device operation. See “Application Examples” on page 7. However,
VCC must equal VIO if sleep mode is used. See Sleep Mode section on
VIO
10, 22, 32, 43,
89, 100
PWR
PCI bus I/O power supply - 3.3V or 5V, detected by the auto-sense circuitry of
the XR17D152. This power supply determines the VOH level of the PCI bus
interface outputs.
(PCI 2.3 signalling compliant at both 3.3V and 5V operation, suitable for uni-
versal form factor add-in card application.)
GND
1, 11, 23, 33,
44, 53, 78, 88
PWR
Power supply common, ground.
NC
63, 64
No Connection.
