Bt8370/8375/8376 is packaged in an 80-pin Metric Quad Flat Pack (MQFP). A

pinout diagram of this device is illustrated in Figure 1-1. Figure 1-2 details a

Bt8370/8375/8376 logic diagram. Pin labels, names, I/O functions, and

descriptions are provided in Table 1-1.

The input pins listed below contain an internal pullup resistor (>50 k

Ω) and

can remain unconnected if the active-high input state is desired. All other unused

input pins should be either pulled up or grounded.

A[7:0]

Address lines unused in INTEL bus mode

XOE

Active-high enables analog bipolar output

MOTO*

Pullup selects INTEL bus mode if unconnected

SYNCMD Pullup selects synchronous processor interface

RCKI

Receive clock unused if analog inputs enabled

TDI

Unused if JTAG not connected

TMS

Disables JTAG if not connected

TCK

Unused if JTAG not connected

RST*

Disables hardware reset if not connected

TDLI

Unused if no external data link

TSIGI

Unused if signaling data not supported by system

bus
