Additional Features

Onboard Interfaces
6.1.1
Optional eMMC 4.5
The conga-TCA3 offers an optional eMMC 4.5 flash onboard the Intel Atom variants. Changes to the onboard eMMC may occur during the
lifespan of the module in order to keep up with the rapidly changing eMMC technology.
The performance of the newer eMMC may vary depending on the eMMC technology.
Note
1. For adequate operation of the eMMC, ensure that at least 15 % of the eMMC storage is reserved for vendor-specific functions."
2. The conga-TCA3 Celeron variants do not offer eMMC
6.1.2
Low Voltage Memory (DDR3L)
The Bay Trail SoC on the conga-TCA3 offers a low voltage memory interface. The memory interface supports 1.35 volts and unbuffered DDR3L
SO-DIMMs. By leveraging this feature set, the conga-TCA3 offers a system optimized for lowest possible power consumption.
Note
The conga-TCA3 supports only DDR3L memory modules. The memory modules in the sockets must be symmetrical - that is, same raw cards
and same memory sizes. Therefore, do not use different memory modules in the memory sockets. Doing so may cause system instability or
memory errors. Also make sure the memory modules support the data transfer rate of the particular variant.
In addition, when using one memory socket, insert the memory module only in the first memory slot on the conga-TCA3 (top side). If the first
memory slot is empty, the SoC will ignore the second memory socket (bottom side). When this happens, the conga-TCA3 will not turn on. See
the Intel's Bay Trail datasheet for more information.
