RS8234
ATM ServiceSAR Plus with xBR Traffic Management
28234-DSH-001-B
Boundary Scan I/O and Loopbacks
The RS8234 includes five pins for Joint Test Action Group (JTAG) Boundary
Scan, for board-level testing. The RS8234 incorporates an internal loopback from
the segmentation coprocessor to the reassembly coprocessor, to facilitate system
diagnostics.
2.9 Electrical/Mechanical
The RS8234 is a CMOS device packaged in a 388 Ball Gate Array (BGA) format.
It operates from a 3.3V power supply and within the standard industrial
temperature range.
may be used. Any I/O (except PCI) that requires a pullup must be tied through a
resistor to 3.3 V and not 5 V.
2.10 Logic Diagram and Pin Descriptions
A functionally partitioned logic diagram of the RS8234 is shown in Figure 2-11.
Pin descriptions, names and input/output assignments are detailed in
The device inputs are tolerant of 5 V signal levels, so external 5 V devices
