ConnectCore XP 270 module
I2C Bus Interface
The PXA270 processor has two I2C (Inter-Integrated Circuit) peripherals: the standard
I2C interface and the power-manager interface (a subset of the standard I2C
interface). Only the standard I2C bus is available externally on the module. The
power I2C bus is used for controlling the PMIC (Power Management IC).
The I2C interface allows the ConnectCore XP 270 to serve as a master and a slave
device on the I2C bus.
Features
I2C compliant (see the I2C Bus Specification , Version 2.0)
Multi-master and arbitration support
Standard-speed operation @ 100 kbps. Power-I2C standard-speed operation
is 40 kbps.
Fast-mode operation @ 400 kbps. Power-I2C fast-mode operation is 160
kbps.
PC Card and CompactFlash Interface
The PC Card interface conforms to the PC Card Standard, Volume 2, Electrical
Specification, Version 1.4 and CF+ and CompactFlash Specification Version 1.4. The
PC Card and CompactFlash interfaces provide control signals to support one or two PC
or CompactFlash card slots.
Features
8- or 16-bit transfer possibilities
Any combination of PC Card and CompactFlash can be used for the two PC
Card sockets.
The PC Card interface supports 8- and 16-bit peripherals and handles
common memory, I/O, and attribute memory accesses.
