Product status: Active

Operating Temperature Range -40 °C to +85 °C RoHS compliant

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.

Software Support (TDRV008-SW-xx) for different operating systems is available.
