CAT1021, CAT1022, CAT1023
Preliminary Information
Doc. No. 3009, Rev. E
Acknowledge Polling
Disabling of the inputs can be used to take advantage of
the typical write cycle time. Once the stop condition is
issued to indicate the end of the host’s write opration, the
CAT1021/22/23 initiates the internal write cycle. ACK
polling can be initiated immediately. This involves issuing
the start condition followed by the slave address for a
write operation. If the device is still busy with the write
operation, no ACK will be returned. If a write operation
has completed, an ACK will be returned and the host can
then proceed with the next read or write operation.
WRITE PROTECTION PIN (WP)
The Write Protection feature (CAT1021 only) allows the
user to protect against inadvertent memory array
programming. If the WP pin is tied to VCC, the entire
memory array is protected and becomes read only. The
CAT1021 will accept both slave and byte addresses,
but the memory location accessed is protected from
programming by the device’s failure to send an
acknowledge after the first byte of data is received.
Read Operations
The READ operation for the CAT1021/22/23 is initiated
in the same manner as the write operation with one
exception, the R/
W bit is set to one. Three different
READ operations are possible: Immediate/Current
Address READ, Selective/Random READ and
Sequential READ.
