WRITE CYCLE LIMITS
7020 FRM T08
The write cycle time is the time from a valid stop condition of a write sequence to the end of the internal erase/program
cycle. During the write cycle, the X24026 bus interface circuits are disabled, SDA is allowed to remain high, and the
device does not respond to its slave address.
Write Cycle Timing
Notes:
(5) Typical values are for T
A
= 25°C and nominal supply voltage (5V)
(6) t
WR
is the minimum cycle time from the system perspective when polling techniques are not used. It is the maximum time the device
requires to perform the internal write operation.
