Smallest MicroTCA-chassis for industrial applications

The NATIVE-mini is the youngest member of the N.A.T. family of MicroTCA chassis, targeting at cost-sensitive applications like digital video and image editing, automation or electronic signal processing with the need for one or two payload slots only.

With its compact dimensions of 260 mm width, 43 mm height (1U) and 302 mm depth the EMV-shielded NATIVE-mini is designed for the insertion of up to two single full-size or mid-size AMC modules (Advanced Mezzanine Card) and therefore aims for applications which require just one or two AMC modules. The integrated "embedded" MCH (MicroTCA Carrier Hub) makes the NATIVE-mini a standard compliant MicroTCA systemproviding an easy migration to larger systems. In relation to the system’s dimensions the eMCH is an optimized version of its bigger family member, the NAT-MCH, taking over  monitoring and management of all system components such as the 150W Open Frame power supply (input voltage range 90 - 264 VAC) or the cooling units which ensure in push-pull-configuration a cooling power of 150 W at an operating temperature of +55°C. By error detection and isolation the system management provides the system reliability which MicroTCA is known for. 



The system integrated "embedded" MCH enables the communication between the AMC modules and the monitoring of the system, including the power and cooling management. The eMCH provides via its 1GbE switch direct access to both AMCs and the system management via the 1GbE-Uplink at the chassis front. The 1GbE switch also allows the direct integration of the system components in an existing network infrastructure. Hereby it is also possible to simply integrate the NATIVE-mini in existing management architectures like e.g. SNMP. The eMCH is fully compatible with the NAT-MCH and therefore offers a natural migration path to bigger systems while keeping already used AMCs.

Application areas

Despite its compact design the NATIVE-mini is compliant to the open MicroTCA standard MTCA.0 and therefore every standard compliant, single full-size or mid-size AMC module can be integrated. The service-friendly design aims for applications which are on the one hand cost-sensitive and get along with only few AMC-modules and on the other hand want to benefit from the proven technological benefits that are offered by MicroTCA (e.g. error detection and isolation, open system management and monitoring, etc.). Due to the fact that the chassis is stackable or mountable in a 19’’ rack the NATIVE-mini is multi-purpose and usable e.g. for the following applications:
  • digital video and image editing
  • automation and machine control
  • electronic signal processing
  • security
  • gateway
