ATL25 Series

Cell Library

Atmel’s ATL25 Series ASICs make use of an extensive library of cell structures, including logic

cells, buffers and inverters, multiplexers, decoders and I/O options. Soft macros are also

available.

These cells are characterized by use of SPICE modeling at the transistor level, with perfor-

mance verified on manufactured test silicon. Characterization is performed over the rated

temperature and voltage ranges to ensure that the simulation accurately predicts the perfor-

mance of the finished product.

Note:

* Stresses beyond those listed under Absolute Maximum Ratings may cause permanent dam-

age to the device. This is a stress rating only; functional operation of the device at these or any

other conditions beyond those indicated in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions for extended periods may affect

device reliability.
