MPC855TCVR50D4

The MPC855T communications controller, part number MPC855TCVR50D4, is a member of the MPC8xx family from NXP Semiconductors, targeted at cost-sensitive general-purpose networking controller applications. This microprocessor excels in low-cost communications and networking products such as SOHO routers, ADSL, and cable modems.

Key features include a high-performance MPC8xx core, a RISC communications processor (CP) embedded in the communications processor module (CPM), and an integrated 10/100-Mbps Fast Ethernet controller. The MPC855T operates at 50MHz with a 3.3V supply voltage and has an operating temperature range of -40°C to 95°C (TA). It supports various Ethernet standards including IEEE 802.3u and offers multiple physical interfaces.

This device is packaged in a 357-PBGA (25x25) with surface mount mounting type. It integrates features like large on-chip transmit and receive FIFOs, address recognition, and support for DRAM controllers. The MPC855T is ideal for applications requiring high-performance Fast Ethernet connectivity without impacting the CPM's performance, making it suitable for multichannel protocol processing, ATM, and Ethernet in a single chip.
