A8904
A. Minimum CHIP SELECT setup time before CLOCK rising edge ........... 100 ns
B. Minimum CHIP SELECT hold time after CLOCK rising edge ................ 150 ns
C. Minimum DATA setup time before CLOCK rising edge .......................... 150 ns
D. Minimum DATA hold time after CLOCK rising edge ............................... 150 ns
E. Minimum CLOCK low time before CHIP SELECT ................................... 50 ns
F. Maximum CLOCK frequency ................................................................ 3.3 MHz
G. Minimum CHIP SELECT high time ........................................................ 500 ns
Note: the A8904 can be directly used in an existing A8902–A application, as the fi ve most
signifi cant bits are reset to zero, which is the default condition for A8902–A operation. The
only consideration when using the A8904 in an A8902-A application, is to ensure the mini-
mum CHIP SELECT high time is at least 500 ns.
