Introducing PX5 FILE

The PX5 FILE system's ultra-small footprint-less than 6KB of instruction memory and 2KB of RAM-makes it perfect for memory-constrained devices requiring a file system. It is also a highly reliable file system with optional fault-tolerant operation. It achieves high performance through customizable caching mechanisms, including logical sectors, FAT entries, and directory search entries. Using PX5 FILE is easy as it provides a native implementation of the LINUX file system API and the industry-standard FAT 12/16/32 formats and Long File Name support. PX5 FILE is fully integrated with PX5 RTOS.

Review PX5 FILE


The PX5 MODULE technology enables the dynamic loading and execution of separately compiled C application code, called "modules." Memory isolation for each module is accomplished via MPU or MMU, which prevents unauthorized access during module execution. PX5 MODULES is fully integrated with the PX5 RTOS, allowing nearly full access to the POSIX pthread APIs as well as API extensions. PX5 Modules are ideal for embedded systems requiring lightweight partial firmware updates and isolation of application code execution.

Functional Safety Certification

The PX5 RTOS has earned certification from SGS-TUV Saar for safety-critical systems. Complying with IEC-61508 SIL 4, IEC-62304 Class C, ISO 26262 ASIL D, and EN 50128 standards, it is deemed suitable for developing safety-related software at the highest integrity levels. SGS-TUV Saar, a collaboration between Germany’s SGS-Group and TUV Saarland, is a premier independent entity for testing and certifying embedded software globally. Standards like IEC 61508, IEC-62304, ISO 26262, and EN 50128 ensure functional safety across diverse sectors such as medical devices, industrial machinery, automobiles, and railway control systems.
