CAES UT32M0R500 Microcontroller

For space applications demanding the highest reliability and radiant tolerant products, CAES offers the UT32M0R500, 32-bit Arm® Cortex® -M0+ microcontroller.

For large fleet, low orbit/short duration applications, we offer our Constellation grade devices. These light weight plastic-packaged microcontrollers use the same internal components as their ceramic counterparts and are screened to our Constellation flow for greater affordability. Both plastic and ceramic microcontrollers are designed for a reduced total cost of ownership through efficient technology reuse across many different applications.

Targeted for applications such as distributed control and command applications, these radiation tolerant microcontrollers include a complete front-end analog signal chain, wide range of digital and communication support.

For added design flexibility, our Arm® microcontrollers integrates two independent CAN 2.0B controllers for primary and redundant controller area network (CAN) topologies. Our microcontrollers, whether plastic or ceramic packaged incorporate a variety of power-saving modes to facilitate the design of low power applications - all are supported by the Arm Keil® Development Tool Environment.

UT32M0R500 Arm Microcontroller Evaluation Board

The UT32M0R500-EVB, evaluation development board, provides a comprehensive and rapid prototyping platform for our Arm® microcontrollers. The ArduinoTM Uno connectivity and full product pinout allow for easy expansion and accessibility.

CAES Software Development
UT32M0R500 Software Development Kit (SDK)

Our Arm® microcontrollers integrate the industry standard Arm Cortex®-M0+ processor that supports a powerful set of development and debug tools from Arm. The Arm Keil MDK development kit and ULNK2 debugger are required and may be downloaded from the Arm website. The software development kit contains API library, driver APIs and example source code to aid in the acceleration of your product development.
