AUSTIN, Texas — June 21, 1999 — Motorola (NYSE:MOT) today announced the much anticipated MPC855T, a streamlined version of its popular MPC860T PowerQUICC Microprocessor. Responding to market demand for a scaled-down chip with exceptional performance, Motorola can now accommodate the Fast Ethernet needs of lower cost equipment. The MPC855T provides a single 10/100 Ethernet port, plus a single SCC (Serial Communications Controller) to support communications protocols such as ATM, HDLC, ISDN, multi-channel HDLC and 10BaseT Ethernet. The flexibility of the MPC855T makes it ideal for equipment such as SOHO and branch office routers, ADSL and cable modems, and intelligent switching hubs.

According to Max Baron, an analyst with Cahner’s In-Stat Group, "Motorola's PowerQUICC MPC855T fills a gaping hole in the cost-sensitive, high performance data communications market."

Motorola’s MPC855T is footprint compatible with existing MPC860 family members and operates at 3.3 volt I/O, whereas other MPC860 family members operate at 5 volts I/O. Pricing for the MPC855T is comparable to Motorola’s MPC850SAR is expected to start at a suggested list price of $25.36 for the 50MHz version in quantities of ten thousand units, with lower costs for larger quantities. This reflects new pricing of PowerQUICC products manufactured in .32µ process technology. General sampling is expected to begin in July, with volume production scheduled for September.

The PowerQUICC family’s highly integrated feature set and strong development tool support can significantly reduce customers’ development cycles and costs. Offering true system-on-a-chip solutions, PowerQUICC family members integrate a high performance PowerPC microprocessor to run high layer software, including RTOS and networking software; a communications processing module with an independent RISC processor for off-loading communications tasks from the PowerPC core; and a system interface unit containing a circuit board’s worth of system control functions, including a versatile memory controller.

The PowerPC architecture also enjoys the broadest third-party tool support of any RISC microprocessor today. "With more than 50 companies offering development tools for the PowerQUICC family, system designers are able to build robust DigitalDNA™ systems that are both high in performance and low in cost", said Mike Shoemake, PowerQUICC program manager for Motorola.
