NXP Semiconductors KMPC8315EVRAGDA

Overview

KMPC8315EVRAGDA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro integrated host processor built on Power Architecture™ e300c3 core, operating at up to 400 MHz with 16 KB instruction and 16 KB data caches, floating-point unit, and MMU support. It integrates dual 10/100/1000 Mbps Ethernet controllers (eTSEC), dual SATA 3 Gbps interfaces, dual PCI Express x1 lanes, DDR1/DDR2 memory controller (up to 266 MHz), and SEC 3.3 security engine - deployed as main CPU in network-attached storage (NAS) and VoIP gateways.

For engineers reviewing the KMPC8315EVRAGDA datasheet, KMPC8315EVRAGDA pinout, KMPC8315EVRAGDA application, or KMPC8315EVRAGDA equivalent, key selection considerations include e300c3 core clock speed, dual SATA 3 Gbps + dual PCIe x1 I/O bandwidth, SEC 3.3 cryptographic acceleration, DDR1/DDR2 memory controller timing, and thermal envelope (TJ = 0–105°C) for industrial embedded deployment.

Technical Context

The KMPC8315EVRAGDA implements a tightly coupled SoC architecture where the e300c3 core interfaces via a high-bandwidth crossbar to dual eTSECs supporting RGMII/SGMII/MII, dual SATA PHYs compliant with SATA Rev 2.5, and two independent SerDes lanes configurable as PCIe x1 or SGMII. Its security engine (SEC 3.3) offloads IPSec, TLS, and iSCSI crypto operations using dedicated AESU, DEU, MDEU, PKEU, and RNG units.

Power management includes D0–D3hot states plus D3warm standby mode - retaining PMC, one eTSEC, and GTM block powered while disabling switchable I/O supplies (GVDD, LVDDx_OFF, NVDDx_OFF). Clocking supports flexible PLL configuration with separate AVDD1/AVDD2 analog rails for core and system APLLs, and strict sequencing requirements between continuous (VDDC, NVDDx_ON) and switchable (VDD, GVDD) supplies.

Key Specifications

Pinout & Package

The KMPC8315EVRAGDA is housed in a 783-pin PBGA package (27 mm × 27 mm, 1.0 mm pitch), RoHS-compliant, with thermal lid. Pin assignments are defined in Section 23 "Package and Pin Listings" of MPC8315EEC Rev. 2.

FAQ

What is the maximum DDR2 data rate supported by KMPC8315EVRAGDA?

KMPC8315EVRAGDA supports DDR2 SDRAM up to 266 MHz data rate (533 MT/s), with 16- or 32-bit bus width, two independently addressable chip selects, and auto-refresh capability. This enables up to 2 GB of DDR2-533 memory using x16 devices, validated per JEDEC standards and documented in Section 7 of MPC8315EEC Rev. 2.

Does KMPC8315EVRAGDA include a hardware security engine?

Yes, KMPC8315EVRAGDA integrates SEC 3.3 - a dedicated security engine supporting AES-128/192/256, SHA-1/256/384/512, DES/3DES, RSA up to 4096-bit, and true random number generation. This is confirmed in Section 2.3 of the MPC8315EEC datasheet and distinguishes it from the non-security MPC8315 variant.

What package type and pin count does KMPC8315EVRAGDA use?

KMPC8315EVRAGDA uses a 783-pin plastic ball grid array (PBGA) package measuring 27 mm × 27 mm with 1.0 mm ball pitch. Pin definitions, including power, clock, DDR, eTSEC, and PCIe signals, are fully specified in Section 23 "Package and Pin Listings" of MPC8315EEC Rev. 2.

Can KMPC8315EVRAGDA operate in low-power D3warm mode?

Yes, KMPC8315EVRAGDA supports D3warm - a low-power standby state where the PMC, one eTSEC, and GTM remain powered while switchable supplies (GVDD, LVDDx_OFF, NVDDx_OFF) are disabled. Wake-up events include Ethernet magic packet, GPIO, or IRQ inputs, enabling sub-100 ms resume, as detailed in Section 2.12.

What is the recommended power-up sequence for KMPC8315EVRAGDA?

The recommended power-up sequence requires applying continuous core voltage (VDDC) before continuous I/O voltages (NVDDx_ON, LVDD2_ON), and switchable core voltage (VDD) before switchable I/O voltages (GVDD, LVDDx_OFF, NVDDx_OFF). PORESET must be asserted until ≥32 SYS_CLK_IN cycles after stabilization, per Figure 3 in Section 3.2 of MPC8315EEC Rev. 2.
