NOTE:
1. The LBO, TMS, TDI, TCK and TRST pins will be internally pulled to V
DD and ZZ will be internally pulled if they are not actively driven in the application.
NOTES:
1. All values are maximum guaranteed values.
2. At f = f
MAX, inputs are cycling at the maximum frequency of read cycles of 1/tCYC; f=0 means no input lines are changing.
3. For I/Os VHD = VDDQ – 0.2V, VLD = 0.2V. For other inputs VHD = VDD – 0.2V, VLD = 0.2V.
4. Only available in 256K x 18 configuration.
