18.4.6 Ready and Hold

Timing requirements (Vcc = 2.7 to 5.5 V, Vss = 0 V, Ta = –40 to 85

°C, f(XIN) = 12 MHz (Note), unless otherwise noted)

g The rise/fall time of an input signal must be 100 ns or less, unless otherwise noted.

18.4 Electrical characteristics

Concerning section “18.4 Electrical characteristic,” the 7735 Group differs from the 7733 Group in the

following sections:

• “18.4.6 Ready and Hold”

• “18.4.8 Memory expansion mode and Microprocessor mode : with no wait”

• “18.4.9 Memory expansion mode and Microprocessor mode : with wait 1”

• “18.4.10 Memory expansion mode and Microprocessor mode : with wait 0”

The other description is the same as that of the 7733 Group. Therefore, refer to part 1:

• “18.4 Electrical characteristics” (page 18-7 in part 1)
