Contains Board Revisions: Yes
Effective On: Jul 30, 2021
Published: July 09, 2021
Products Affected: TS-7970
Dear Valued Customer,
We are contacting you today to announce we are [[ NOTICE_TITLE_URL
]]. Technologic Systems strives to ensure the longevity of our products,
while continually improving our products, so with the End of Life of the WiFi/Bluetooth module on the TS-7970 we are happy to announce an
upgraded WiFi/Bluetooth solution including 802.11a/b/g/n/ac (2.4 GHz, 5
GHz) and Bluetooth 4.2 BR/EDR/LE(Class2). Initially announced December
of 2019 we are notifying customers today that the final PCB revision
will be Rev G, and we will begin using this revision to fulfill some
orders starting this month, we anticipate full production transition
before the end of the year.
In order to support
this change all customers will be transitioned to the new Revision G of
the TS-7970. All Revision G Boards will ship with an updated pre-loaded software image. Customers using WiFi will be required to update their software images to support the new module. Once updated software will support both the legacy LS Research module and the newer Silex module. A new DDR3 RAM has also been
qualified and will begin shipping with Revision G boards. Revision G is nearly identical to the Revision F that has been available to testing,
the only difference is the implementation of a revision detection I/O
The affected products are: TS-7970 (and most custom variants)
When LS Research's planned replacement for the TS-7970's original WiFi module fell through, Technologic Systems purchased a number of extra modules and began the search for a replacement device that would bring feature improvements to the WiFi/Bluetooth solution on the TS-7970. We are pleased to announce the next revision of the TS-7970 will include the Silex SX-SDMAC-2832S+ based on the Qualcom QCA9377-3. This radio supports 802.11a/b/g/n/ac (2.4 GHz and 5 GHz operation) Wave 2 MU-MIMO and Bluetooth 4.2 BR/EDR/BLE “Smart Ready”. The module carries FCC/IC/CE/MIC certifications, and is a similar size to the previous module, supporting minimal layout changes to minimize impact on any certifications obtained for TS-7970 based products.
In order to support this change, the TS-7970 shipping software has been upgraded to a Linux 4.9 Kernel with Debian Buster. Please review the separate announcement regarding this transition:
All customers not using the
WiFi/Bluetooth features who's production processes install a complete
kernel/application image can continue to use the same image they are
using today. The Revision G hardware maintains backwards compatibility
for all other features and does not require an updated software image.
All customers with custom U-Boot or Linux Kernel's, or other TS-7970 images please consult the User Manual for instructions. Feel free to contact us at email@example.com for assistance with this transition.
For more information please review the TS-7970 User Manual.:
In conjunction with the new revision of the hardware Technologic Systems
is also transitioning the RAM to a new DDR3 RAM device from Alliance
Memory in order to continue supporting a long life cycle on the
TS-7970. We have fully tested this change on all products over the full temperature range of the product and this change has no impact to
functionality, software, or performance, we are timing the release as
much as possible of
the new RAM to the Rev G release to allow for easier tracking of
deployments. Some customers may see an earlier release on the Revision E hardware to address material availability challenges the current
economy is presenting.
Please contact us before Jul 30, 2021 ([[ NOTICE_EFFECTIVE_DATE_HUMAN_DIFF ]]) if you are anticipating any troubles in transitioning so that we can support your efforts and plan appropriately.
Technologic Systems appreciates your business.
