Notes:
1. This parameter is characterized and is not 100% tested.
Device Operation
CLOCK and DATA TRANSITIONS:
The SDA pin is nor-
mally pulled high with an external device. Data on the SDA
pin may change only during SCL low time periods (refer to
Data Validity timing diagram). Data changes during SCL
high periods will indicate a start or stop condition as
defined below.
START CONDITION:
A high-to-low transition of SDA with
SCL high is a start condition which must precede any other
command (refer to Start and Stop Definition timing dia-
gram).
STOP CONDITION:
A low-to-high transition of SDA with
SCL high is a stop condition. After a read sequence, the
stop command will place the EEPROM in a standby power
mode (refer to Start and Stop Definition timing diagram).
ACKNOWLEDGE:
All addresses and data words are seri-
ally transmitted to and from the EEPROM in 8-bit words.
The EEPROM sends a zero to acknowledge that it has
received each word. This happens during the ninth clock
cycle.
STANDBY MODE:
The AT24C164 features a low power
standby mode which is enabled: a) upon power-up and b)
after the receipt of the STOP bit and the completion of any
internal operations.
MEMORY RESET:
After an interruption in protocol, power
loss or system reset, the AT24C164 can be reset by follow-
ing these steps:
(a) Clock up to 9 cycles, (b) look for SDA high in each cycle
while SCL is high and then (c) create a start condition as
SDA is high.
