2-Wire I2C-Compatible Serial Interface
A register file controls the various internal switches and
operating modes of the MAX3301E/MAX3302E through
a simple 2-wire interface operating at clock rates up to
400kHz. This interface supports data bursting, where
multiple data phases can follow a single address phase.
UART Mode
Set uart_en (bit 6 in control register 1) to 1 to place the
MAX3301E/MAX3302E in UART mode. D+ transfers
data to DAT_VP and SE0_VM transfers data to D- in
UART mode.
General-Purpose Buffer Mode
Set gp_en (bit 7 in special-function register 1) and
dat_se0 (bit 2 in control register 1) to 1, set uart_en (bit 6
in control register 1) to 0, and drive
OE/INT low to place
the MAX3301E/MAX3302E in general-purpose buffer
mode. Control the direction of data transfer with dmi-
nus_dir and dplus_dir (bits 3 and 4 of special-function
register 1, see Tables 2 and 14).
Serial Addressing
The MAX3301E/MAX3302E operate as a slave device
that sends and receives control and status signals
through an I2C-compatible 2-wire interface. The inter-
face uses a serial data line (SDA) and a serial clock line
(SCL) to achieve bidirectional communication between
master(s) and slave(s). A master (typically a microcon-
troller) initiates all data transfers to and from the
MAX3301E/MAX3302E and generates the SCL clock
that synchronizes the data transfer (Figure 13).
The MAX3301E/MAX3302E SDA line operates as both an
input and as an open-drain output. SDA requires a
pullup resistor, typically 4.7kΩ. The MAX3301E/
MAX3302E SCL line only operates as an input. SCL
requires a pullup resistor if there are multiple masters on
the 2-wire interface, or if the master in a single-master
system has an open-drain SCL output.
Each transmission consists of a start condition (see
Figure 14) sent by a master device, the MAX3301E/
MAX3302E 7-bit slave address (determined by the state
of ADD), plus an R/
W bit (see Figure 15), a register
address byte, one or more data bytes, and a stop condi-
tion (see Figure 14).
