The Embedded I/O Company

The TPMC541 provides dedicated A/D and D/A sequencer

units for periodic analog-to-digital and digital-to-analog

conversions at a configurable conversion rate.

In sequencer mode, A/D conversion data is temporarily

stored in an on-board data buffer and is transferred to

system memory by PCI master DMA transfer while D/A

conversion data is fetched from buffers in system memory

by PCI master DMA transfer and is temporarily stored in

an on-board data buffer.

The sequencers provide a Frame Mode for repetitive

frames of A/D and D/A conversions upon an internal or

external trigger signal event.

Conversion clock (conversion rate) and frame trigger

signals may be generated on-board for internal use and

may also be driven out on P14 rear I/O if the card is

operating as a master card in a Multi-Board configuration.

The conversion clock (conversion rate) and frame trigger

signals may also be sourced externally via the P14 rear

I/O interface if the card is operating as a slave card in a

Multi-Board configuration.

The TPMC541 also features 8 ESD protected digital I/O

lines. Each digital I/O line has a dedicated line transmitter

with individual output enable control and a dedicated line

receiver. The line receivers are always enabled, so the

digital I/O line level can always be monitored.

Each digital I/O line input is capable of generating an

interrupt triggered on rising edge, falling edge or both.

Additionally, a glitch filter can be configured to get rid of

bouncing on the digital I/O inputs.

Each digital I/O line has a 4.7kΩ pull resistor to a common

reference.

The

common

pull

resistor

reference

is

programmable by software to +3.3V, +5V or GND.

Each TPMC541 is factory calibrated. The correction data

is stored in an on-board serial EEPROM unique to each

PMC module. The correction data values may be used to

perform a hardware correction for any A/D channel and

input range and any D/A channel and output range.

The analog input, analog output and digital I/O signals are

accessible via a Mini D Ribbon (MDR68) type front I/O

connector.
