4.10 SP7: I2C Peripherals

There are several I2C peripherals on the board. See picture below for locating the different

components on the board. The I2C addresses for the individual components are given in the

schematic.

 Configuration E2PROM, 64kbit. This chip contains version information about the OEM Base

Board.

 LM75 Temperature sensor.

 3-axis Accelerometer (MMA7455). Note that the two interrupt outputs are not connected but

available on JP5.

 Port expander (PCA9532) with 8 LEDs and 4 pushbuttons. The Card Detect and Write Protect

signals from the SD/MMC memory card connector are also connected to this chip. LED22/23

are positioned above SW2, LED24/25 are positioned above SW3, LED26/27 are positioned

above SW4 and LED28/29 are positioned above SW5.
