Radiation-Tolerant Microcontroller-Based System-on-Module (ZSOM-M01)

ZSOM™-M01 is a radiation-tolerant System-on-Module (SOM) embodying an ARM Cortex-M0+ microcontroller and ZES’ proprietary radiation-hardened technology for mitigating Single-Event-Latchup (SEL) and Single-Event-Upset (SEU) in irradiation environments.  It can be configured within the Arduino-Compatible platform, leveraging available open-source code.

 

ZSOM™-M01 enables a quick and reliable payload development platform for space-based applications.

Summary
  • Low power embedded microcontroller-based SOM with SEL protection and SEU protection
    •  SEL protection enabled by ZES100 Radiation-Hardened Latchup Detection and Protection (LDAP-IC) chip. 
    •  Extendable to protect other external COTS part(s) operated at 3.3V
  • External FRAM with SEU protection in Triple-Modular-Redundancy (TMR): enabled by ZES400 Radiation-Hardened Voter-IC
  • Proprietary error-detection-and-correction (EDAC) C-code for detecting/correcting multiple errors in SRAMs/Flash within the ARM Cortex-M0+ microcontroller.
    • 2,200x lesser soft error than Single-Error-Correction-Double-Error-Detection (SECDED)
  • High Reliability Manufacturing PCB (Class III)
  • Arduino-Compatible Integrated Design Environment (IDE)
  • Proton test up to 200MeV @ fluence > 1011 particles/cm2
  • Total Ionizing Dose (TID): 20k rad @ Co-60

 

Target Applications

  • Low power embedded applications for CubeSat payloads for Low-Earth-Orbit (LEO)
  • Telemetry/data-communication applications
  • Low error-rate data protection applications
  • Instrumentation and control for high reliability applications

 

Data protection demonstration (picture data) in SRAMs:
(a) Original data, (b) Corrupted Data with 14 bits flipped  and (c) Corrected data (with ZES EDAC)

 

Advanced Data Protection

  • An image is stored inside the SRAMs of the ZSOMTM-M01, and the data is protected by ZES EDAC code
  • Hypothetically the data is then randomly corrupted with 14 errors (14 bits flipped out of 29kB)
  • The ZES EDAC successfully recovers the original data thereby showcasing its ability to maintain data integrity in high-radiation environments

 

 

 

Extendable SEL Protection for External COTS Components

  • Configurable to protect external COTS components operating at 3.3V from SELs
  • Utilizes Pin 31 to power and protect external devices (sensors, analog, digital, or mixed-signal circuits)
  • Shares SEL protection via onboard ZES100 LDAP-IC (for currents <0.5A)
