Acromag’s New Multi-function I/O XMC Mezzanine Modules Feature A/D, D/A, and Digital I/O Channels to Conserve I/O Slots

The XMC730 provides flexible, high-density I/O with high-performance DMA to solve a variety of SWaP-challenges. 

XMC730 Multi-function I/O

•  Analog input
•  Analog output
•  Digital I/O
•  Counter/timers
•  Conduction-cooled options

XMC730 mezzanine modules provide a variety of I/O functions on a single plug-in card. These new high-density modules perform both high-speed and high resolution A/D and D/A conversion and also handle digital I/O and counter/timer functions.
