NXP Semiconductors MPC8315EVRADDA

Overview

MPC8315EVRADDA from NXP (formerly Freescale) is a PowerQUICC II Pro integrated host processor built on Power Architecture™ e300c3 core, operating up to 400 MHz with 16 KB instruction and 16 KB data caches, floating-point unit, and MMU. It integrates dual 10/100/1000 Mbps Ethernet controllers (eTSEC), dual SATA 3 Gbps interfaces, dual PCI Express x1 lanes, DDR1/DDR2 memory controller, security engine (SEC 3.3), USB 2.0 dual-role controller, and TDM interface - targeting network-attached storage, VoIP gateways, and industrial controllers.

For engineers reviewing the MPC8315EVRADDA datasheet, MPC8315EVRADDA pinout, MPC8315EVRADDA application, or MPC8315EVRADDA equivalent, key selection considerations include its e300c3 core performance, dual SATA 3 Gbps support, SEC 3.3 cryptographic acceleration, RGMII/SGMII Ethernet flexibility, and D3warm low-power standby mode for always-on embedded systems.

Technical Context

The MPC8315EVRADDA implements a tightly coupled SoC architecture with an e300c3 core executing at up to 400 MHz, backed by separate 16 KB L1 instruction and data caches and full IEEE 754-compliant FPU. Its SerDes block dynamically configures between PCI Express x1 and SGMII modes, enabling flexible high-speed interconnect routing without hardware redesign.

Memory subsystem includes a unified 16-/32-bit DDR1/DDR2 SDRAM controller supporting up to 266 MHz data rates and two physical banks, while the security engine (SEC 3.3) offloads IPSec, TLS, and iSCSI crypto operations via dedicated AESU, DEU, MDEU, PKEU, and RNG units - all accessible through a descriptor-based DMA interface independent of CPU cycles.

Key Specifications

Pinout & Package

The MPC8315EVRADDA is housed in a 783-pin PBGA package (27 mm × 27 mm, 1.0 mm pitch), RoHS-compliant, with thermal lid and exposed die paddle for enhanced heat dissipation in industrial environments.

FAQ

What is the maximum DDR2 SDRAM density supported by the MPC8315EVRADDA?

The MPC8315EVRADDA DDR2 controller supports up to 4-Gbit devices with x8/x16 data ports, enabling configurations such as two 2-Gbit chips on a 32-bit bus for 512 MB total capacity. It does not support x4 DDR2 devices. The controller operates at up to 266 MHz data rate, delivering peak theoretical bandwidth of 853 MB/s in 32-bit mode. This capability is confirmed in Section 2.4 of the MPC8315EEC Rev. 2 datasheet.

Does the MPC8315EVRADDA support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, the MPC8315EVRADDA's dual eTSECs include full IEEE 1588 v2 hardware timestamping with sub-100 ns resolution on both packet ingress and egress. The timestamp registers are accessible via memory-mapped I/O and synchronized to the internal CSB clock domain. This feature is explicitly documented in Section 2.10 and Figure 1 of the MPC8315EEC Rev. 2 specification.

What power supply sequencing requirements apply to the MPC8315EVRADDA during startup?

The MPC8315EVRADDA requires switchable core voltage (VDD) to ramp before switchable I/O supplies (GVDD, LVDDx_OFF, NVDDx_OFF), and continuous core voltage (VDDC) before continuous I/O supplies (LVDDx_ON, NVDDx_ON). PORESET must remain asserted until ≥32 SYS_CLK_IN cycles after all supplies stabilize. These constraints are defined in Section 3.2 "Power Sequencing" of the MPC8315EEC Rev. 2 datasheet to prevent I/O contention and latch-up.

Can the MPC8315EVRADDA operate in PCI Express endpoint mode?

Yes, each of the two PCI Express interfaces on the MPC8315EVRADDA can be independently configured as either root complex or endpoint via configuration registers. Endpoint mode supports MSI and INTx interrupts, 32-/64-bit addressing, and 128-byte maximum payload size - enabling use as a high-speed peripheral in host systems. This is specified in Section 2.8 of the MPC8315EEC Rev. 2 hardware documentation.

Is the security engine (SEC 3.3) present in all MPC8315EVRADDA units?

Yes, the MPC8315EVRADDA includes the full SEC 3.3 security engine - unlike the non-"E" variant MPC8315, which omits this block entirely. SEC 3.3 provides dedicated hardware acceleration for AES, DES/3DES, SHA-256/384/512, RSA-4096, and true random number generation. This distinction is clearly stated in the document's Overview section and Section 2.3 of the MPC8315EEC Rev. 2 datasheet.
