MC8641DTVU1333JE

Microprocessors Overview

The MC8641DTVU1333JE is a dual-core microprocessor based on the PowerPC e600 architecture. It features two 32-bit cores operating at a maximum clock frequency of 1333 MHz. The device integrates a unified 1-Mbyte L2 cache with ECC and separate 32-Kbyte L1 instruction and data caches per core. It supports DDR and DDR2 SDRAM via dual 64-bit memory controllers. Key interfaces include four enhanced three-speed Ethernet controllers (eTSECs), PCI Express, Serial RapidIO, High-Speed Serial Interfaces (HSSI), I2C, and a Local Bus Controller. The processor operates within a junction temperature range of 0 to 105 °C and utilizes a 1023-pin FC-CBGA package.

Microprocessors Procurement Notes

Verify the specific revision level and voltage requirements against the official MPC8641D Hardware Specifications datasheet before integration. Confirm that the power supply sequencing adheres strictly to the recommended ramp-up times and voltage tracking tolerances defined in the electrical characteristics section. Ensure thermal management solutions are adequate for the maximum power dissipation values at the target operating frequency and junction temperature.

Microprocessors Selection Notes

Select this component when a dual-core PowerPC solution with integrated networking and serial interfaces is required. Consider the specific core voltage options available for different frequency bins. Evaluate the memory controller support for both DDR and DDR2 types based on system design constraints. Verify compatibility with existing software environments targeting the PowerPC e600 ISA and OpenPIC interrupt architecture.
