Cryptoauthentication Device - Digi ConnectCore 8X Hardware Reference Manual

The ConnectCore 8X System-on-module
Non-wireless variants
The dedicated PCIe clock generator is not internally populated in the non-wireless variants, so to use
the PCI Express interface it must be populated externally (see the ConnectCore 8X SBC Pro reference
design).
The following control lines can also be used externally in non-wireless variants:
PCIE_LGA_OUT_CTRL0_WAKE_B
n
PCIE_LGA_OUT_CTRL0_CLKREQ_B
n
PCIE_LGA_OUT_CTRL0_PERST_B
n
Note There are other PCIe-related pads on the ConnectCore 8X module: F7, F8, F9, G20, G21, G23,
G24. Leave these pins unconnected.

CryptoAuthentication device

The ConnectCore 8X module includes an Atmel CryptoAuthentication Device. This is a highly secure
cryptographic co-processor with secure hardware-based key storage. It includes the following
features:
Performs high-speed public key (PKI) algorithms (ECDSA and ECDH). NIST standard P256
n
elliptic curve support.
SHA-256 hash algorithm with HMAC option.
n
256-bit key length.
n
Storage for up to 16 keys.
