Figure 15. Random Address Read Sequence
– One bit of the slave command byte is a R/W bit. The
Word Address
The word address is either supplied by the master or
obtained from an internal counter. The internal counter
is undefined on a power-up condition.
Operational Notes
The device powers-up in the following state:
– The device is in the low power standby state.
– The WEL bit is set to ‘0’. In this state it is not possi-
– SDA pin is the input mode.
– RESET/RESET Signal is active for

R/W bit of the Slave Address Byte defines the oper-
ation to be performed. When the R/W bit is a one,
then a read operation is selected. A zero selects a
write operation.

Data Protection
The following circuitry has been included to prevent
inadvertent writes:
– The WEL bit must be set to allow write operations.
– The proper clock count and bit sequence is required
– A three step sequence is required before writing into
