TPMC321 Conduction Cooled 64 Digital TTL I/O or 32 Differential I/O

Conduction cooled PMC module offer 64 Digital TTL I/O or 32 Differential I/O. The TPMC321-10R has 64 ESD-protected 5V-tolerant TTL lines, the TPMC321-11R provides 32 differential I/O lines using EIA-422 / EIA-485 compatible, ESD-protected line transceivers. The TPMC321-12R provides 32 differential I/O lines using M-LVDS line transceivers.

All lines are individually programmable as input, output or tri-state. The receivers are always enabled, which allows determining the state of each I/O line at any time. Each TTL I/O line has a pull-up resistor. The pull-up voltage is selectable to be either +3.3V or +5V. The differential I/O lines are terminated by 120Ω resistors.

All input lines can generate an interrupt. The signal edge handling is programmable to interrupt on rising, falling or both edges of the input signal. Interrupts can be enabled and disabled for each bit. For interrupt source detection, the status of each line can be read from interrupt status registers.

The TPMC321 provides rear I/O via P14.

A wide range of drivers is available: Linux, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
