SC9-TOCCATA • CompactPCI® Serial CPU Board • 11th Generation Intel® Processors
Memory
The Tiger Lake H processors feature two channels x64 of DDR4 SDRAMs with support of ECC
(Error Correction Code). On the SC9-TOCCATA, one channel is realized with up to 18 memory
devices 8/16Gb soldered to the board (Memory Down) and delivers a capacity of up to 32GB at a
clock frequency of 3200MHz.
The 2nd memory controller channel is wired to a socket, for installing an optional 260-pin ECC
SODIMM module, thus allowing a simple expansion of system memory (max. module height =
1.25 inch). Supported are unbuffered DDR4 ECC SODIMMs (72-bit) with V
DD
=1.2V featuring on-die
termination (ODT), according the PC4-3200 specification. Maximum module size is 32GB. For best
performance the module memory capacity should be equal/symmetric to the memory down
capacity. Since the SODIMM socket may be hidden below a low profile mezzanine module or side
card, it is recommended that the SODIMM module should be assembled by EKF.
By means of Intel® Total Memory Encryption (Intel® TME) all memory contents and instruction sets
from CPU to memory are encrypted with AES 128-bit encryption. This is a hardware based method
to protect against cold boot memory attacks.
In addition, the SC9-TOCCATA is equipped with SPI Flash non-volatile memory, for UEFI/BIOS and
firmware storage.
