NXP Semiconductors
LPC2378
Fast communication chip
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
7.18 SD/MMC card interface
The Secure Digital and Multimedia Card Interface (MCI) allows access to external SD
memory cards. The SD card interface conforms to the SD Multimedia Card Specification
Version 2.11.
7.18.1
Features
The MCI interface provides all functions specific to the SD/MMC memory card. These
include the clock generation unit, power management control, and command and data
transfer.
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 controllers
The LPC2378 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 LPC2378 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.
