MPC8250TS/D Rev. 0.1, 11/2001 MPC8250 PowerQUICC ™ II Technical Summary Freescale Semiconductor, Inc... The MPC8250 PowerQUICC II is a versatile communications processor that integrates a high-performance G2 microprocessor, a flexible system integration unit, and many communications peripheral controllers that can be used in a variety of applications, particularly in communications and networking systems. The MPC8250 is a Footprint-compatible, lower-cost version of the MPC8260. The core is an embedded variant of the 603e microprocessor, referred to as the G2 core, with 16 Kbytes of instruction cache, 16 Kbytes of data cache, and a floating-point unit (FPU). The system interface unit (SIU) consists of a flexible memory controller that interfaces to almost any user-defined memory system and many other peripherals, making this device a complete system on a chip. The communications processor module (CPM) includes all the peripherals found in the MPC860, with the addition of three high-performance communications channels that support 10/100 Ethernet, Transparent, and HDLC. The MPC8250 has dedicated hardware that can handle up to 128 full-duplex, time-division-multiplexed logical channels. This document describes the functional operation of the MPC8250, with an emphasis on peripheral functions. Additional information about the G2 microprocessor core can be found in the MPC603e RISC Microprocessor User’s Manual, REV 3 (order number: MPC603EUM/AD). 1.
