5.0 Electrical Characteristics
5.2 – 5.2
Notes:
*1.
Operation over a wide range of voltages is guaranteed except where a sudden voltage
change occurs during access.
Pins A0, D0–D7, E(RD), R/W (WR) and CS
Pins CL, FR, M/S and RES
Pins D0–D7
Pin FR
Pins A0, E (RD), R/W
(WR), CS, CL and RES
Applicable when pins D0–D7 and FR are at high impedance.
This value is current consumption when a vertical stripe pattern is written at t
CYC
. Current
consumption during access is nearly proportionate to access frequency (t
CYC
). Only TDD (1)
is consumed while no access is made.
