FAQ

What is the maximum DDR memory speed supported by T1020NSE7MQB?

The T1020NSE7MQB supports DDR3L/4 memory at up to 1600 MT/s with ECC capability. This interface provides bandwidth sufficient for concurrent packet buffering, OS execution, and application data handling in high-throughput networking applications. The controller implements on-die termination and programmable timing parameters to ensure signal integrity across varying board layouts and memory modules. T1020NSE7MQB's memory subsystem is validated for use with JEDEC-compliant DDR3L and DDR4 components meeting specified voltage and timing specifications.

Does T1020NSE7MQB include hardware virtualization support?

Yes, T1020NSE7MQB includes hardware-assisted virtualization via the e5500 core's hypervisor privilege level. This enables kernel-based virtual machines (KVM), Linux containers, and commercial hypervisors from Green Hills and Enea. The T1020NSE7MQB's PAMU (Peripheral Access Management Unit) enforces memory isolation between VMs, while DPAA resources can be partitioned across virtual environments. T1020NSE7MQB has been validated with NXP's Linux SDK and reference virtualization stacks for secure multi-tenant deployments.

How many Ethernet ports does the integrated switch in T1020NSE7MQB support?

The T1020NSE7MQB integrates an 8-port Gigabit Ethernet switch capable of wire-speed forwarding for all standard packet sizes. It supports IEEE 802.1Q VLAN tagging, ACL-based packet filtering, and priority-based QoS scheduling. The switch connects internally via eight dedicated SGMII lanes from the SerDes block and exposes external interfaces through RGMII or SGMII PHY connections. T1020NSE7MQB's switch is fully managed via MDIO and supports runtime reconfiguration without reset.

What cryptographic algorithms does the Security Engine (SEC) in T1020NSE7MQB accelerate?

The T1020NSE7MQB integrates SEC 5.4, which accelerates AES-128/192/256 (ECB/CBC/CTR/GCM), 3DES, SHA-1/224/256/384/512, HMAC-SHA, RSA up to 4096-bit, and random number generation. Throughput reaches 5 Gb/s for bulk symmetric encryption, enabling line-rate IPsec and TLS offload. All SEC operations are accessible via the CAAM driver in NXP's Linux SDK. T1020NSE7MQB's SEC includes tamper detection and volatile key storage aligned with NXP's QorIQ Trust Architecture.

Is T1020NSE7MQB pin-compatible with other QorIQ T1 family processors?

Yes, T1020NSE7MQB is pin-compatible with T1040NSE7MQB and T1022NSE7MQB in the FC-PBGA-783 package. This allows hardware reuse across dual-core and quad-core variants, simplifying platform scaling. Pin compatibility covers power, DDR, SerDes, PCIe, USB, SATA, and peripheral interfaces. However, unused pins differ between variants - for example, T1020NSE7MQB leaves certain PCIe and Ethernet signals unconnected versus T1040NSE7MQB. T1020NSE7MQB's pin mapping is documented in NXP's T1 Family Hardware Design Guide.
