The EP220 and EP224 inputs and outputs respond a maximum of 1 µs  
after V power-up (V = 4.75 V), or after a power-loss/power-up  
sequence. All macrocells that are programmed as registers are set to a  
logic low on power-up.

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.  
Design Security  
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 (ICC). When the Turbo Bit is  
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  
this data sheet.  
Turbo Bit  
EP220 and EP224 devices are fully functionally tested and guaranteed.  
Complete testing of each programmable EPROM configuration element  
and all internal logic elements ensures 100% programming yield. Figure 3  
shows AC test conditions.
