Read mode
Read mode
The M48T58/Y is in the READ Mode whenever W (WRITE Enable) is high, E1 (Chip Enable
1) is low, and E2 (Chip Enable 2) is high. The unique address specified by the 13 Address
Inputs defines which one of the 8,192 bytes of data is to be accessed. Valid data will be
available at the Data I/O pins within Address Access time (tAVQV) after the last address input
signal is stable, providing that the E1, E2, and G access times are also satisfied. If the E1,
E2 and G access times are not met, valid data will be available after the latter of the Chip
Enable Access times (tE1LQV or tE2HQV) or Output Enable Access time (tGLQV).
The state of the eight three-state Data I/O signals is controlled by E1, E2 and G. If the
outputs are activated before tAVQV, the data lines will be driven to an indeterminate state
until tAVQV. If the Address Inputs are changed while E1, E2 and G remain active, output data
will remain valid for Output Data Hold time (tAXQX) but will go indeterminate until the next
Address Access.
