We have been receiving good feedback from current and potential customers about our DOSonCHIP™ product line.

It is appreciated -- please keep it up, we enjoy hearing from you!

We try to respond to as many inquires as possible; if there is a delay, please be patient during our "crunch time."

Our short-term goal is to provide a firmware release that includes host-side source code, followed by IC's. Below are some common requests we have received:

1. Supply our U.S. distributor SparkFun with IC's,
2. Set up additional distribution outside of the U.S.,
3. Increase write and read speeds,
4. Provide SDHC support,
5. Simplify SPI and UART to eliminate handshake lines,
6. Provide improved doc's and host-side code to speed-up development.

We hear your requests and are working to meet them.

We are working as fast as possible to complete our new firmware release! It is a major upgrade (yes, it will work with your existing DOSonCHIP hardware) that includes new architectural innovations to dramatically improve throughput. It departs from our existing host interface in order to improve efficiency and enable a stable path for future improvements. In addition, we will be supplying royalty-free host-side source code in C to simplify development.

We have completed testing on read rates and have a peak throughput of 300 KBytes/s (sustained over a 512 byte sector), and an initial test of a long sustained read over 100 KBytes/s. This is similar over both SDHC and SD cards.

We are currently finishing debugging the write function and should have test numbers shortly. We are expecting similar speeds as read.

Over the past year, we have been focusing on meeting customer demand for our products. This year, we are re-prioritizing and preparing a new firmware release that meets the growing customer needs. The top areas we are targeting (all work with existing hardware) are:

1. Speed increase for write & read
2. Host side source code: royalty-free
3. Improved documentation
4. Elimination of physical handshake lines (reduction in required pins)
5. SDHC compatibility

The initial firmware release will target SPI host communication (UART for firmware upgrade). We have completed and tested "read" commands, and have written most of our "write" code. It is a complete firmware architecture, design, and code overhaul that is geared to meet the growing multimedia data speeds demanded by our top customers.

We are very excited about this new architecture as we believe it will enable us to provide a strong platform to provide free performance enhancements to our existing customers and enable best-in-class products going forward.

In order to focus on our upcoming firmware release, we are suspending our online store for the next several weeks. We apologize for this inconvenience, but we are prioritizing our new development over revenue in order to show our commitment to deliver the new release as soon as possible.

In addition, we are retooling our online store to improve the ordering experience and enable more purchase options.

Please contact our distributors for available stock.
All pending orders will be fulfilled.
