LPC2361/62
Single-chip 16-bit/32-bit MCU
Synchronous serial communication
Master or slave operation
8-frame FIFOs for both transmit and receive
4-bit to 16-bit frame
DMA transfers supported by GPDMA
7.17 I
2
C-bus serial I/O controllers
The LPC2361/2362 each contain three I
2
C-bus controllers.
The I
2
C-bus is bidirectional, for inter-IC control using only two wires: a serial clock line
(SCL), and a serial data line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the
capability to both receive and send information (such as memory). Transmitters and/or
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I
2
C is a multi-master bus, it can be
controlled by more than one bus master connected to it.
The I
2
C-bus implemented in LPC2361/2362 supports bit rates up to 400 kbit/s (Fast
I
2
C-bus).
7.17.1
Features
I
2
C0 is a standard I
2
C compliant bus interface with open-drain pins.
I
2
C1 and I
2
C2 use standard I/O pins and do not support powering off of individual
devices connected to the same bus lines.
Easy to configure as master, slave, or master/slave.
Programmable clocks allow versatile rate control.
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 I
2
C-bus can be used for test and diagnostic purposes.
7.18 I
2
S-bus serial I/O controllers
The I
2
S-bus provides a standard communication interface for digital audio applications.
The
I
2
S-bus specification
defines a 3-wire serial bus using one data line, one clock line,
and one word select signal. The basic I
2
S connection has one master, which is always the
master, and one slave. The I
2
S interface on the LPC2361/2362 provides a separate
transmit and receive channel, each of which can operate as either a master or a slave.
