ASIC success story
Application
State-of-the-art downhole drilling monitoring and evaluation systems require high performance at extreme temperature profiles. CSS has partnered with a leading supplier of downhole monitoring devices to create a data-acquisition ASIC that operates at temperatures of 200°C.

Custom solution from CSS
This ASIC integrates the functionality to acquire pressure and temperature data through frequency comparison and then transmit the acquired data through I2C. The chip has three acquisition channels and includes reference oscillators used in the frequency comparison. The chip also contains power management and other signal processing.

Key features
- Three XTAL oscillators
- I2C communication link
- Frequency comparison logic
- Operational up to 200°C

Tell us what the chip would need to do and roughly how many you build a year. That is usually enough for a straight answer on whether a custom ASIC is the right call.draft
Closing call to action is written, not sourced. The current site has no call to action on case study pages. This heading and paragraph were written to fill that gap — they are underlined on the page. Replace with approved wording or remove before launch.
Layout: every section now has a right-hand column. Application carries a key specs panel, Custom Solution carries the die layout, Key Features runs in two columns. Previously only Custom Solution had anything on the right, so a third of the page sat empty on the other two sections.
The alternative — a photograph beside Application, as the current site does — was not used because both available images are already on this page: the photograph is the banner, the die layout is beside Custom Solution. A third image would have to be sourced for all 24 case studies.
