ISL24201 Programming
The ISL24201 accepts I2C bus address and data when the WP
pin is at or above VIH (>0.7VDD). The ISL24201 ignores the I2C
shows the serial data format for writing the register and
programming the EEPROM. Figure 14 shows the serial data
format for reading the DAC register. Table 2 shows the truth table
for reading and writing the device.
Programming the EEPROM memory transfers the current DAC
register value to the EEPROM and occurs when the control bits
select the programming mode and the AVDD voltage is >10.8V.
After the EEPROM programming cycle is started, the WP pin can
be returned to logic low while the while it completes, which takes
a maximum of 100ms.
The ISL24201 uses a 6 bit I2C address, which is “100111xx”. The
I2C Bus Signals
The ISL24201 uses fixed voltages for its I2C thresholds, rather
than the percentage of VDD described in the I2C specification
(see Table 3). This should not cause a problem in most systems,
but the I2C logic levels in a specific design should be checked to
ensure they are compatible with the ISL24201.
