NXP Semiconductors MPC8245LVV266D

Overview

MPC8245LVV266D from Freescale Semiconductor is a 32-bit PowerPC™ MPC603e-based integrated processor combining a superscalar CPU core with PCI bridge, SDRAM memory controller, and peripheral logic block. It operates at 266 MHz CPU frequency, supports 66 MHz PCI bus and up to 133 MHz memory bus, and targets embedded control systems requiring high integration and deterministic I/O handling.

For engineers reviewing the MPC8245LVV266D datasheet, MPC8245LVV266D pinout, MPC8245LVV266D application, or MPC8245LVV266D equivalent, key selection criteria include its 266 MHz CPU speed, 1.8 V ±100 mV core supply requirement, TBGA-352 package, dual UART support, and PCI 2.2-compatibility with 5.0-V tolerance.

Technical Context

The MPC8245LVV266D integrates a full-featured MPC603e core (16-Kbyte instruction cache, 16-Kbyte data cache, FPU, MMU) with a dedicated peripheral logic block connected via a 64-bit internal bus. Core and peripheral logic operate at independent frequencies-core PLL referenced to peripheral PLL-enabling power-performance tradeoffs through nap/doze/sleep modes.

Its memory controller supports up to 2 Gbytes of SDRAM with programmable timing, ECC/parity options, and 32-/64-bit data path; the PCI interface delivers 66 MHz operation, dual address cycle (DAC), hardware-enforced coherency, and five request/grant arbitration pairs for host or agent mode use.

FAQ

What is the core voltage requirement for MPC8245LVV266D?

The MPC8245LVV266D requires a core supply voltage of 1.8 V ±100 mV DC under nominal operating conditions. This specification applies specifically to the 266 MHz speed grade and mandates tight regulation to avoid timing violations or thermal instability. The I/O supply (OVDD) must be 3.3 V ±0.3 V, and memory bus drivers (GVDD) require 3.3 V ±5%. All voltage rails must follow strict sequencing per Figure 2 in the hardware specifications.

Does MPC8245LVV266D support PCI 64-bit addressing?

Yes, MPC8245LVV266D supports 64-bit PCI addressing in master mode via Dual Address Cycle (DAC), enabling access to memory spaces beyond 4 GB. This capability is implemented in the PCI interface unit and requires proper configuration of the ATU (Address Translation Unit) outbound registers. Agent mode does not support DAC; the device must be configured as a PCI host to utilize this feature.

Can MPC8245LVV266D operate in little-endian mode?

Yes, MPC8245LVV266D supports both big-endian and little-endian operation, selected via the PCI configuration space register bit ENDIAN. This setting affects byte ordering on the PCI bus and internal data path alignment. The default is big-endian, but switching to little-endian is fully supported and validated for interoperability with x86-based PCI peripherals and drivers.

What is the maximum SDRAM capacity supported by MPC8245LVV266D?

The MPC8245LVV266D supports up to 2 Gbytes of SDRAM across one to eight banks, using 16-, 64-, 128-, 256-, or 512-Mbit memory devices. Capacity depends on bank count, device density, and data bus width (32- or 64-bit). The memory controller implements programmable timing parameters and supports ECC or parity for error detection/correction in mission-critical applications.

Is MPC8245LVV266D pin-compatible with other MPC824x variants?

MPC8245LVV266D is pin-compatible with MPC8241LVV266D and MPC8245LVV300D within the same TBGA-352 package variant, sharing identical ball map and electrical characteristics for core, I/O, and memory interfaces. However, it is not compatible with higher-pin-count derivatives like MPC8272LVR266D (PBGA-484), which uses a different package and enhanced peripheral set.
