NXP Semiconductors MPC8306SVMACDCA

Overview

MPC8306SVMACDCA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro integrated communications processor featuring an e300c3 Power Architecture core, dual integer units, 16 KB instruction and 16 KB data L1 caches, and a 16-bit DDR2 SDRAM controller supporting up to 266 MHz data rate. It integrates a QUICC Engine block with five unified communication controllers (UCCs), two 10/100 Mbps Ethernet MII/RMII interfaces, USB 2.0 HS host/device/OTG, dual I²C, DUART, SPI, and real-time clock - deployed in residential gateways and industrial control systems.

For engineers reviewing the MPC8306SVMACDCA datasheet, MPC8306SVMACDCA pinout, MPC8306SVMACDCA application, or MPC8306SVMACDCA equivalent, key selection considerations include DDR2 timing compliance at 1.8 V, QUICC Engine protocol flexibility (HDLC/TDM/Ethernet), e300c3 core voltage tolerance (1.0 V ±50 mV), and thermal operation up to 105 °C junction temperature.

Technical Context

The MPC8306SVMACDCA implements a dual-clock domain architecture: the e300c3 core runs at up to 333 MHz with its own PLL, while the QUICC Engine operates independently at up to 233 MHz using a separate PLL - enabling power-optimized concurrent processing of network protocols and application code. Its DDR2 controller supports 14 address lines, 16-bit data width, auto-refresh, and on-the-fly CKE-based power management.

Communication subsystems are partitioned across dedicated hardware blocks: five UCCs handle protocol-specific framing and serialization for Ethernet, HDLC, and TDM; the USB 2.0 dual-role controller supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps, host-only) modes; and the enhanced local bus controller (eLBC) provides eight chip selects with NAND/parallel NOR boot capability and programmable burst lengths up to eight beats.

Key Specifications

Pinout & Package

The MPC8306SVMACDCA is housed in a 516-ball PBGA package (19 mm × 19 mm, 1.0 mm pitch) with ball map defined per Freescale document MPC8306SEC Rev. 1 Section 19. Signal multiplexing is extensive: 56 GPIO pins share functions with UART, I²C, SPI, timers, and interrupt lines; DDR2 signals occupy dedicated balls with controlled impedance routing requirements.

FAQ

What is the maximum DDR2 SDRAM data rate supported by the MPC8306SVMACDCA?

The MPC8306SVMACDCA supports a maximum DDR2 SDRAM data rate of 266 MHz on its 16-bit interface, delivering up to 4.256 GB/s peak bandwidth. This is achieved with 14 address lines and two chip selects, allowing configurations up to 512 MB total capacity. The controller includes auto-refresh, on-the-fly CKE power management, and supports 64-Mbit to 2-Gbit DDR2 devices with x8/x16 data ports - all verified per Freescale MPC8306SEC Rev. 1 Section 6.

Does the MPC8306SVMACDCA support USB On-The-Go functionality?

Yes, the MPC8306SVMACDCA includes a USB 2.0 dual-role controller that supports On-The-Go (OTG) operation, enabling dynamic switching between host and device roles. It complies with USB 2.0 specification and supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps, host-only) modes. The ULPI interface allows connection to external PHYs without integrated transceivers - details confirmed in Section 11 of the MPC8306SEC Rev. 1 hardware specification.

What are the power supply sequencing requirements for the MPC8306SVMACDCA?

The MPC8306SVMACDCA requires core voltage (VDD = 1.0 V) to be applied before I/O supplies (GVDD = 1.8 V and OVDD = 3.3 V) to prevent bus contention. Specifically, VDD must reach 90% of nominal before GVDD/OVDD exceed 0.7 V, followed by ≥32 SYS_CLK_IN cycles after power stabilization before releasing PORESET. No specific power-down sequence is mandated. These requirements are documented in Section 2.2 of MPC8306SEC Rev. 1 and ensure reliable initialization without excessive current draw.

How many Ethernet interfaces does the MPC8306SVMACDCA support, and what standards are implemented?

The MPC8306SVMACDCA supports two independent 10/100 Mbps Ethernet interfaces via its five unified communication controllers (UCCs), each configurable for MII or RMII physical layer interfaces compliant with IEEE Std. 802.3. UCC1 and UCC2 are typically assigned to Ethernet, while remaining UCCs handle HDLC, TDM, or other serial protocols. The implementation includes full MAC-layer functionality with DMA acceleration and checksum offload - as specified in Sections 1 and 8 of MPC8306SEC Rev. 1.

Is the MPC8306SVMACDCA pin-compatible with other PowerQUICC II Pro processors?

No, the MPC8306SVMACDCA is not pin-compatible with other PowerQUICC II Pro processors such as MPC8313EVMAGD or MPC8315EVMAGD despite sharing the same 516-ball PBGA package size. Ball assignments differ significantly - particularly for DDR2, USB, and QUICC Engine signal groups - requiring unique PCB layouts. Freescale documentation confirms distinct ball maps per device; migration between variants necessitates board redesign, though software compatibility is maintained across the e300c3 core family.
