TPMC682

3 x 16 bit I/O Ports with 512 Word FIFO and Handshake

Application Information

The TPMC682 is a standard single-width 32 bit PMC with

three 16 bit TTL digital input/output lines controlled by

handshake signals. These handshake signals run over an

additional 8 bit input and an 8 bit output port. Interlocked

or pulsed handshake protocol is provided. Each I/O port

has a 512 words deep FIFO. All I/O lines are protected by

bus transceivers and ESD protection devices.

The PLX PCI9030 PCI target chip is used for the PCI

interface.

An interrupt can be generated on INTA, when the filling

level of a FIFO exceeds the value of the individually

programmable threshold. Each port has a programmable

timeout counter for input direction of data.

The TPMC682 provides front panel I/O via a HD68 SCSI-3

type connector and rear panel I/O via P14.
