X24C01A
The data output is sequential, with the data from address n
followed by the data from n + 1. The address counter
Sequential Read
Sequential Read can be initiated as either a current
address read or random access read. The first word is
for read operations increments all address bits, allowing the
entire memory contents to be serially read during
transmitted as with the other modes, however, the
master now responds with an acknowledge, indicating it
one operation. At the end of the address space (address 127),
the counter “rolls over” to address 0 and the
requires additional data. The X24C01A continues to
output data for each acknowledge received. The read
X24C01A continues to output data for each acknowledge
received. Refer to Figure 9 for the address, acknowledge
and data transfer sequence.
operation is terminated by the master, by not responding with
an acknowledge and by issuing a stop condition.
