NXP Semiconductors KMPC8245LVV350D

Overview

KMPC8245LVV350D from Freescale Semiconductor 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 up to 350 MHz CPU frequency, supports 66 MHz PCI bus and 100 MHz memory bus, and targets embedded control applications requiring high integration and deterministic timing.

For engineers reviewing the KMPC8245LVV350D datasheet, KMPC8245LVV350D pinout, KMPC8245LVV350D application, or KMPC8245LVV350D equivalent, key selection criteria include its 350 MHz CPU speed, 3.3 V/5.0 V-tolerant PCI interface, dual UART support, ECC-capable SDRAM controller, and dynamic power management modes (doze/nap/sleep).

Technical Context

The KMPC8245LVV350D integrates a full-featured MPC603e core with 16-Kbyte instruction and data caches, lockable per-way L1 cache, and IEEE 1149.1 JTAG debug interface. Its peripheral logic block provides synchronous 64-bit processor-to-peripheral bus with decoupled address/data paths and store-gathering capability.

It implements two independent PLLs-one for the CPU core and one for peripheral logic-enabling asynchronous operation at different frequencies while maintaining coherency. The memory controller supports up to 2 Gbytes of SDRAM across 1–8 banks with programmable timing, ECC or parity, and 32-/64-bit data path widths.

FAQ

What is the maximum operating frequency of the KMPC8245LVV350D CPU core?

The KMPC8245LVV350D CPU core is rated for a maximum frequency of 350 MHz under recommended operating conditions (VDD = 2.0/2.1 V ±100 mV). This rating assumes proper thermal management, correct PLL_CFG[0:4] configuration, and stable 66 MHz PCI_SYNC_IN input. Operation above 350 MHz is not guaranteed and violates the device's qualified specification.

Does the KMPC8245LVV350D support ECC for SDRAM memory?

Yes, the KMPC8245LVV350D supports ECC for SDRAM memory through its integrated memory controller. It implements full ECC on the 64-bit data path with dedicated syndrome generation and correction logic. ECC mode requires enabling the appropriate bits in the memory controller configuration registers and using SDRAM devices with sufficient width (e.g., x72 or x80) to accommodate ECC bits.

What power management modes are available on the KMPC8245LVV350D?

The KMPC8245LVV350D supports three hardware power management modes: Doze (1.5 W typical), Nap (0.6 W typical), and Sleep (0.3 W typical). These modes progressively disable clocks to non-essential blocks, reduce voltage domains, and gate internal power rails. Entry and exit are controlled via MSR[IP] bit writes and require specific sequence timing per the MPC8245UM reference manual.

Is the KMPC8245LVV350D pin-compatible with other MPC824x variants?

Yes, the KMPC8245LVV350D is pin-compatible with all members of the MPC824x family sharing the 352-ball TBGA package, including MPC8241, MPC8245, and MPC8247. Identical ball map, power/ground assignments, and signal definitions enable drop-in replacement across speed grades and feature subsets, provided firmware and board-level timing constraints are validated.

What is the function of the DLL in the KMPC8245LVV350D memory interface?

The Delay-Locked Loop (DLL) in the KMPC8245LVV350D synchronizes SDRAM_CLK outputs to SDRAM_SYNC_IN with sub-cycle precision. It compensates for board trace delays and temperature drift to maintain setup/hold timing margins. The DLL lock range is frequency-dependent (see Figure 7–10), and DLL_EXTEND bit enables extended range for higher-frequency operation.
