Major features of the MPC8360E/58E are as follows:
• e300 PowerPC processor core (enhanced version of the MPC603e core)
— Operates at up to 667 MHz (for the MPC8360E) and 400 MHz (for the MPC8358E)
— High-performance, superscalar processor core
— Floating-point, integer, load/store, system register, and branch processing units
— 32-Kbyte instruction cache, 32-Kbyte data cache
— Lockable portion of L1 cache
— Dynamic power management
— Software-compatible with the Freescale processor families implementing the Power
Architecture™ technology
• QUICC Engine unit
— Two 32-bit RISC controllers for flexible support of the communications peripherals, each
operating up to 500 MHz (for the MPC8360E) and 400 MHz (for the MPC8358E)
— Serial DMA channel for receive and transmit on all serial channels
