Promotes CSS NV Register
|CSS NV Register Block Diagram |
ON Semiconductor Foundry Services is now promoting the CSS NV Register for use in their C5 Foundry processes while CSS still provides and supports this IP. The CSS NV Register is a latch based non-volatile memory circuit that is ideal for use in trimming analog circuits. The NV Register is compatible for most of the C5 processes at ON as it only requires the standard processing layers (including Poly 2).
The great thing about the NV Register is that once programmed it will automatically come up in the programmed state when power is applied - nothing else is required. Also, since it is latched based, it draws no current in normal operation. The NV Register can easily be configured to the number of bits needed for your trimming application (7 bits will provide a setting to 1% accuracy and 10 bits will provide 0.1% setting accuracy).
At CSS we use the NV Register in most of our custom ASIC designs. The most typical applications include trimming analog circuits for higher accuracy and reconfiguring the ASIC for a variety of applications. Other common applications include the storage of the part number, a serial number or a date code. The applications seem to be endless. We have found the NV Register is an essential capability in our design work.
The NV Register is a self contained programmable non-volatile memory. It includes a built-in programming voltage generator so no additional voltages are required. It also programs with a single store operation and includes numerous serial and parallel interface options for entering data and reading out contents of the NV Register.
Specifications for the NV Register may be downloaded from the Custom Silicon Solutions website (CSS Classic NV Register Spec.pdf). Also, if you have questions, please feel free to call (949-797-9220) or email Mike McDaid at [email protected].
