SC18IS600/601
SPI to I2C-bus interface
6.3 External clock input (SC18IS601)
In this device, the processor clock is derived from an external source driving the CLKIN
pin. The clock rate may be from 0 Hz up to 18 MHz.
6.4 I2C-bus serial interface
I2C-bus uses two wires (SDA and SCL) to transfer information between devices connected
to the bus, and it has the following features:
Bidirectional data transfer between masters and slaves
Multi-master bus (no central master)
Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus
Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus
Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer
The I2C-bus may be used for test and diagnostic purposes.
provides a byte-oriented I2C-bus interface that supports data transfers up to 400 kHz.
(Refer to
UM10204, “I2C-bus specication and user manual”.)
6.5 Serial Peripheral Interface (SPI)
The host communicates with the SC18IS600/601 via the SPI interface. The
SC18IS600/601 operates in Slave mode up to 3 Mbit/s.
The SPI interface has four pins: SCLK, MOSI, MISO, and CS.
SCLK, MOSI and MISO are typically tied together between two or more SPI devices.
Data ows from the master to the SC18IS600/601 on the MOSI (Master Out Slave In)
pin and ows from SC18IS600/601 to the master on the MISO (Master In Slave Out)
pin. The SCLK signal is an input to the SC18IS600/601.
CS is the slave select pin. In a typical conguration, an SPI master selects one SPI
device as the current slave. An SPI slave device uses its CS pin to determine whether
it is selected. The CS pin may be tied LOW if it is the only device on the bus.
Typical connections are shown in Figure 12.
