Current Address Read
Internally the X24C01A contains an address counter
that maintains the address of the last word accessed,
incremented by one. Therefore, if the last access (either
a read or write) was to address n, the next read operation
would access data from address n + 1. Upon receipt of
the slave address with R/
W
set to one, the X24C01A
issues an acknowledge and transmits the eight bit word
during the next eight clock cycles. The read operation is
terminated by the master; by not responding with an
acknowledge and by issuing a stop condition. Refer to
Figure 7 for the sequence of address, acknowledge and
data transfer.
Random Read
Random read operations allow the master to access any
memory location in a random manner. Prior to issuing
the slave address with the R/
W
bit set to one, the master
must first perform a “dummy” write operation. The mas-
ter issues the start condition, and the slave address
followed by the word address it is to read. After the word
address acknowledge, the master immediately reissues
the start condition and the slave address with the R/
W
bit
set to one. This will be followed by an acknowledge from
the X24C01A and then by the eight bit word. The read
operation is terminated by the master; by not responding
with an acknowledge and by issuing a stop condition.
Refer to Figure 8 for the address, acknowledge and data
transfer sequence.
