CP3010-SA
2.2 Memor y
The CP3010-SA supports a soldered, dual-channel (144-bit), Double Data Rate (DDR3L) memory with-
out Error Checking and Correcting (ECC) running at 1333 MHz. The available memory configuration can
be either 4 GB or 8 GB.
However, when the internal graphics controller is enabled, the amount of memory available to appli-
cations is less than the total physical memory in the system. The SoC dynamically allocates the proper
amount of system memory required by the operating system and the application.
2.3 Watchdog Timer
The CP3010-SA provides a Watchdog timer that is programmable for a timeout period ranging from
125 ms to 4096 s in 16 steps.
The Watchdog timer provides the following modes or operation:
»
Timer-only mode
»
Reset mode
»
Interrupt mode
»
Dual-stage mode
In dual-stage mode, a combination of both interrupt and reset is generated if the Watchdog is not ser-
viced.
2.4 Batter y
The CP3010-SA is provided with an UL-recognized CR2025, 3.0 V, “coin cell” lithium battery for the RTC.
Power for the RTC may be provided either from the 4 HP / 8 HP CP3010-SA or from the backplane / rear
transition module, i.e. only one battery may be used at a time in a system. When a battery is installed,
refer to the operational specifications of the battery as this determines the storage temperature of the
CP3010-SA.
2.5 Flash Memor y
The CP3010-SA provides flash interfaces for the uEFI BIOS and the SATA flash.
2.5.1 SPI Boot Flash for uEFI BIOS
The CP3010-SA provides two 8 MB SPI boot flashes for two separate uEFI BIOS images, a standard SPI
boot flash and a recovery SPI boot flash. The switching mechanism for the uEFI BIOS recovery is con-
trolled via the DIP switch SW1, switch 2. The SPI boot flash includes a hardware write protection op-
tion, which can be configured via the uEFI BIOS. If write protection is enabled, the SPI boot flash
cannot be written to.
Note:
The uEFI BIOS code and settings are stored in the SPI boot flashes. Changes made to the
uEFI BIOS settings are available only in the currently selected SPI boot flash. Thus, switch-
ing over to the other SPI boot flash may result in operation with different uEFI BIOS code
and settings.
