TPMC680

8 x 8 Bit Digital Inputs/Outputs (5V TTL)

Application Information

The TPMC680 is a standard single-width 32 bit PMC

module offering 64 bit of TTL I/O arranged in 8 x 8 bit

ports. Direction of the I/O lines is software programmable

for each of the 8 bit ports. Each 8 bit port is built up using

a TTL bus transceiver. Each line is protected against ESD

and overvoltage.

Each input can generate an interrupt. Signal edge

handling is programmable to interrupt on rising and/or

falling edge of the input signal. Interrupts can be enabled

and disabled for each bit. For interrupt source detection

the status of each bit can be read from the interrupt status

register.

The TPMC680 supports three basic modes of operation:

standard byte I/O with interrupts, 2 x 16 bit port with

handshake and 1 x 32 bit port with handshake. The two

handshake modes offer double buffered inputs or outputs

and interlocked or pulsed handshake output protocol.

In byte I/O mode it is possible to read or write

synchronously all 64 lines.

The TPMC680 provides front panel I/O via a HD68 SCSI-3

type connector and rear panel I/O via P14.
