NXP Semiconductors
LPC2470
Flashless 16-bit/32-bit microcontroller
Conforms to
Multimedia Card Specification v2.11
.
Conforms to
Secure Digital Memory Card Physical Layer Specification, v0.96.
Can be used as a multimedia card bus or a secure digital memory card bus host. The
SD/MMC can be connected to several multimedia cards or a single secure digital
memory card.
DMA supported through the GPDMA controller.
7.19 I
2
C-bus serial I/O controller
The LPC2470 contains 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-bus is a multi-master bus and can
be controlled by more than one bus master connected to it.
The I
2
C-bus implemented in LPC2470 supports bit rates up to 400 kbit/s (Fast I
2
C-bus).
7.19.1
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.
7.20 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 LPC2470 provides a separate transmit
and receive channel, each of which can operate as either a master or a slave.
