Stratix IV GT Edition Reference Manual

Table 2–17 lists the flash memory map storage for two FPGA bitstreams (factory and

user) as well as 40 MB of reserved user space for storage of PFL configuration settings,

software binaries, and other data relevant to the targeted FPGA design (Nios II

applications). For the EP4S100G2F40I1N FPGA device, each FPGA bitstream can be a

maximum of 94.54 Mb (less than 12 MB). Hence, the factory and user POF space is set

at 12 MB.

Table 2–18 lists the flash memory device component reference and manufacturing

information.

Components and Interfaces

This section describes the temperature measurement and power measurement

circuitries and the board’s communication ports.

Temperature Measurement

Figure 2–7 shows the block diagram for the temperature measurement circuitry.

Temperature monitoring for the Stratix IV die is achieved by using a MAX1619

temperature sense device. The MAX1619 connects to the FPGA by a 2-wire SMBus

interface. The

OVERTEMPn

and

ALERTn

signals from the MAX1619 connect to the FPGA

to allow it to immediately sense a temperature fault condition and turn on the

attached fan. The FPGA controls the fan based on the

OVERTEMPn

signal from the

MAX1619, or the fan can be set to always ON.
