unsuccessful data transfers. An unsuccessful data trans-
fer happens if a receiving device is busy or if a system
fault has occurred. In the event of an unsuccessful data
transfer, the bus master reattempts communication at a
later time.
Slave Address
The MAX1363/MAX1364 have a 7-bit I2C slave
address. The slave address is selected using A0. The
MAX1363/MAX1364 (EUB, MEUB, and LEUB) have
three base address options, allowing up to six devices
concurrently per I2C bus (see Table 1).
The MAX1363/MAX1364 continuously wait for a START
condition followed by its slave address. When the device
recognizes its slave address, it is ready to accept or
send data depending on the R/
W bit (Figure 6).
HS I2C Mode
At power-up, the MAX1363/MAX1364 bus timing is set
for fast mode (F/S mode, up to 400kHz I2C clock), which
limits the conversion rate to approximately 22ksps.
Switch to high-speed mode (HS mode, up to 1.7MHz
I2C clock) to achieve conversion rates up to 94.4ksps.
The MAX1363/MAX1364 convert up to 133ksps in moni-
tor mode, regardless of I2C mode. If conversion results
are unread, I2C bandwidth limitations do not apply (see
the
Monitor Mode section).
Select HS mode by addressing all devices on the bus
with the HS-mode master code 0000 1XXX (X = don’t
care). After successfully receiving the HS-mode master
code, the MAX1363/MAX1364 issue a NACK, allowing
SDA to be pulled high for one clock cycle (Figure 7).
After the NACK, the MAX1363/MAX1364 operate in HS
mode. Send a repeated START (Sr) followed by a slave
address to initiate HS-mode communication. If the mas-
ter generates a STOP condition, the MAX1363/
MAX1364 return to F/S mode. Use a repeated START
condition (Sr) in place of a STOP condition to leave the
bus active and the mode unchanged.
