NXP Semiconductors MPC8245TVV300D-NXP

Overview

MPC8245TVV300D from NXP (formerly Freescale) is a 32-bit PowerPC™ MPC603e-based integrated processor combining a superscalar CPU core with PCI bridge, SDRAM memory controller, DUART, DMA, I2C, and interrupt controllers in a single TBGA package. It operates at 300 MHz CPU frequency, supports 66 MHz PCI bus and up to 133 MHz memory bus, and targets embedded control systems requiring real-time I/O, PCI host/agent functionality, and low-power operation.

For engineers reviewing the MPC8245TVV300D datasheet, MPC8245TVV300D pinout, MPC8245TVV300D application, or MPC8245TVV300D equivalent, key selection criteria include its 300 MHz CPU speed, 32-bit PCI 2.2 compliance, dual UART support, dynamic power management (nap/doze/sleep), and 1.8–2.0 V core supply requirement under nominal conditions.

Technical Context

The MPC8245TVV300D integrates a full-featured MPC603e core-featuring 16-Kbyte instruction and data caches, floating-point unit (software-enabled), MMU, and branch prediction-with a tightly coupled peripheral logic block. Its dual PLL architecture enables independent clocking: one for the CPU core (300 MHz), another for peripheral logic (PCI/SDRAM), maintaining synchronous bus coherency despite frequency separation.

System-level integration includes a 32-bit PCI interface compliant with PCI 2.2 (5.0-V tolerant), programmable memory controller supporting up to 2 Gbytes of SDRAM across 1–8 banks, and dual-channel DMA with scatter-gather capability. The device implements store-gathering for PCI writes, hardware-enforced coherency, and configurable endian mode (big/little), enabling flexible system partitioning in telecom, industrial, and networking applications.

FAQ

What is the maximum supported SDRAM capacity for the MPC8245TVV300D?

The MPC8245TVV300D supports up to 2 Gbytes of SDRAM memory across one to eight banks, using 16-, 64-, 128-, 256-, or 512-Mbit memory devices. This capacity is achieved through its programmable memory controller with 32- or 64-bit data path and configurable row/column address mapping. The MPC8245TVV300D datasheet specifies bank decoding and timing register settings required to initialize each configuration.

Does the MPC8245TVV300D support little-endian operation?

Yes, the MPC8245TVV300D supports selectable big- or little-endian operation via configuration registers accessible during boot. Endianness is set independently for PCI transactions and internal processor data paths, allowing interoperability with both legacy big-endian peripherals and modern little-endian software stacks. The MPC8245TVV300D Reference Manual documents the specific PMC register bits controlling this behavior.

What are the power supply sequencing requirements for the MPC8245TVV300D?

The MPC8245TVV300D requires strict voltage sequencing: VDD/AVDD/AVDD2 must stabilize before OVDD/GVDD/LVDD, with all supplies within specification before asserting HRST_CPU/HRST_CTRL. Per Figure 2, OVDD/GVDD must ramp after VDD/AVDD/AVDD2, and LVDD (5 V) must ramp last. Violating this sequence risks latch-up or undefined reset behavior. The MPC8245TVV300D Hardware Specifications document defines timing windows and voltage separation cautions in Table 2.

Can the MPC8245TVV300D operate as both PCI host and PCI agent?

Yes, the MPC8245TVV300D is explicitly designed to function as either a PCI host or PCI agent controller, as stated in Section 2 of the Hardware Specifications. In host mode, it initiates PCI transactions to peripherals; in agent mode, it responds to accesses from an external PCI host. Configuration is controlled via PCI configuration space registers and boot-time strap pins. The MPC8245TVV300D supports dual address cycle (DAC) for 64-bit addressing in master mode.

What debug interfaces does the MPC8245TVV300D provide?

The MPC8245TVV300D includes IEEE Std 1149.1® (JTAG) test interface for boundary-scan and emulation, plus COP (Controller On Probe) interface for real-time debugging. It also features debug address signals, MIV (Memory Interface Valid) cycle marker, and programmable watchpoint inputs for hardware-triggered breakpoints. These capabilities are documented in Section 5 of the MPC8245TVV300D Hardware Specifications and fully supported by CodeWarrior development tools.
