DC ELECTRICAL CHARACTERISTICS
(
Ta=0 ~ 70
°C
, Vcc=3.3V ,unless otherwise noted)
The operation mode of the M5M512R88DJ is determined by
a combination of the device control inputs S, W and OE.
Each mode is summarized in the function table.
A write cycle is executed whenever the low level W
overlaps with the low level S. The address must be set-up
before the write cycle and must be stable during the entire
cycle.
The data is latched into a cell on the trailing edge of W or
S, whichever occurs first, requiring the set-up and hold time
relative to these edge to be maintained. The output enable
input OE directly controls the output stage. Setting the OE at
a high level, the output stage is in a high impedance state,
and the data bus
contention problem in the write cycle is eliminated.
A read cycle is excuted by setting W at a high level and
OE at a low level while S are in an active state (S=L).
When setting S at high level, the chip is in a non-
selectable mode in which both reading and writing are
disable. In this mode, the output stage is in a high-
impedance state, allowing OR-tie with other chips and
memory expansion by S.
Signal-S controls the power-down feature. When S goes
high, power dissapation is reduced extremely. The access
time from S is equivalent to the address access time.
