Design Security
EP220 and EP224 devices contain a programmable Security Bit that
controls access to the data programmed into the device. When this bit is
turned on, a proprietary design implemented in the device cannot be
copied or retrieved. This feature provides a high level of design security,
because programmed data within EPROM cells is invisible. The Security
Bit that controls this function, as well as all other program data, is reset
when a device is erased.
Turbo Bit
The -10A and -12 speed grades of the EP220 and EP224 devices contain a
programmable Turbo Bit to control the automatic power-down feature
that enables the low-standby-power mode (I
turned on, the low-standby-power mode is disabled. All AC values are
tested with the Turbo Bit turned on. When the device is operating with the
Turbo Bit turned off (non-turbo mode), a non-turbo adder must be added
to the appropriate AC parameter to determine worst-case timing. The
non-turbo adder is specified in the
“AC Operating Conditions”
tables in
