Description
The ATC18RHA is fabricated on a proprietary 0.18 µm, six-metal-layers CMOS pro-
cess intended for use with a supply voltage of 1.8V ± 0.15V. Table 1 shows the range
of recommended operating conditions for which Atmel library cells have been
characterized.
The Atmel cell libraries and memory compilers have been designed and or character-
ized in order to be compatible with each other. Simulation representations exist for
three types of operating conditions. They correspond to three characterization condi-
tion sets defined as follows:
• MIN conditions:
–– TJ = -55°C
–– VDD (cell) = 1.95V
– – Process = fast (0.95)
• TYP conditions:
–– TJ = +25°C
–– VDD (cell) = 1.8V
– – Process = typical (1)
