could result in data being overwritten. Note that for
any write mode, the generation by the master of the
STOP condition starts the internal memory pro-
gram cycle. All inputs are disabled until the comple-
tion of this cycle and the ST24/25E16 will not
respond to any request.
Minimizing System Delay by Polling On ACK.
During the internal Write cycle, the ST24/25E16
disable itself from the bus in order to copy the data
from the internal latches to the memory cells. The
maximum value of the Write time (t
W
) is given in the
AC Characteristics table, this timing value may be
reduced by an ACK polling sequence issued by the
master.
The sequence is:
– Initial condition: a Write is in progress (see Fig-
ure 7).
– Step 1: the Master issues a START condition
followed by a Device Select byte. (1st byte of
the new instruction)
– Step 2: if the ST24/25E16 are internally writ-
ing, no ACK will be returned. The Master goes
back to Step1. If the ST24/25E16 have termi-
nated the internal writing, it will issue an ACK.
The ST24/25E16 are ready to receive the sec-
ond part of the instruction (the first byte of this
instruction was already sent during Step1).
