MPC8540CPX667JB

Overview

The MPC8540CPX667JB is a 32-bit microprocessor from the PowerQUICC III family, operating at a core frequency of 667 MHz. It integrates an e500 core with 32 KB L1 instruction and data caches and a 256 KB L2 cache/SRAM. The device features two three-speed Ethernet controllers (TSECs), a RapidIO controller, PCI/PCI-X support, and a DDR SDRAM controller with ECC. It utilizes a 783-pin flip-chip plastic ball grid array package.

Feature Summary
