NOTES:
1. V DD , OPT X , and V DDQX must be set to appropriate operating levels prior to
applying inputs on the I/Os and controls for that port.
2. OPT X selects the operating voltage levels for the I/Os and controls on that port.
If OPT X is set to V DD (2.5V), then that port's I/Os and controls will operate at 3.3V
levels and V DDQX must be supplied at 3.3V. If OPT X is set to V SS (0V), then that
port's I/Os and address controls will operate at 2.5V levels and V DDQX must be

supplied at 2.5V. The OPT pins are independent of one another—both ports can
operate at 3.3V levels, both can operate at 2.5V levels, or either can operate

at 3.3V with the other at 2.5V.
3. When REPEAT X is asserted, the counter will reset to the last valid address loaded
via ADS X .
4. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when
asserted. All static inputs, i.e., PL/ FT x and OPTx and the sleep mode pins
themselves (ZZx) are not affected during sleep mode. It is recommended that
boundry scan not be operated during sleep mode.
5. Due to limited pin count, JTAG is not supported in the DR208 package.
6. Address A 17x is a NC for the IDT70T3599. Also, Addresses A 17x and A 16x are
NC's for the IDT 70T3589.
7. Chip Enables and Byte Enables are double buffered when PL/ FT = V IH , i.e., the
signals take two cycles to deselect.
