PEmicro Revises eSAP Programming Image Format for Expanded Capacity and Unrivaled Efficiency

Apr 08, 2025

PEmicro has updated and improved the eSAP programming image format; version 3 is the latest iteration. This represents a major upgrade that redefines what's possible by not only enhancing efficiency and speed but also dramatically expanding the capacity of images loaded into the Cyclone.

Expanded Capacity

One of the updates in the new programming image format, eSAP version 3, is the significant increase in image capacity. Images up to 32 MB are supported by the Cyclone—a fourfold improvement over the previous maximum of around 8 MB. This leap in capacity empowers you to manage more complex, feature-rich projects and paves the way for innovations that were once limited by file size constraints.

Encoding Efficiency

Beyond the capacity boost, version 3 also introduces an encoding mechanism that streamlines data handling. By rethinking how data is packaged, the new ESAP Images are now only about 40% of the size of the initial S19 file used to create them. This reduction in file size not only saves storage space but also enhances the overall efficiency of the configuration process.

Faster Deployment

The combination of a more efficient encoding mechanism and reduced file sizes translates directly into faster processing speeds. Loading eSAP Images into the Cyclone is now quicker than ever.

Security Without Compromise

Efficiency and capacity improvements do not come at the expense of security. ESAP Images Version 3 maintains full user key based encryption, ensuring that while images are more compact and quicker to load, the user's data remains fully protected. PEmicro's commitment to robust security protocols guarantees that the user's intellectual property and sensitive information are secure every step of the way. The images also have updated hashing mechanisms to stay on top of the latest algorithms to verify the integrity of the image.

The Impact on Workflow

With the transition to eSAP version 3, the user is effectively transforming their entire embedded systems workflow. Users can expect:

  • Expanded Capacity: Load images up to 32 MB, opening the door to more advanced applications.
  • Reduced File Sizes: Benefit from lower storage requirements and more efficient data handling.
  • Faster Loading Times: Experience accelerated deployment into the Cyclone, streamlining the user's testing and development cycles.
  • Unchanged Security: Enjoy the peace of mind that comes with robust full encryption protecting the user's valuable data.

The latest versions of PEmicro software automatically generate the new version of the image format, and the latest SDK and Cyclone Firmware support both new and old image formats.

Looking Ahead

The release of eSAP images v3 signals an important step forward in embedded systems development. Expanded capacity and improved efficiency should allow engineers to tackle increasingly complex challenges. PEmicro continues to innovate development and production technologies, so users should keep an eye out for more updates.
