The MPC860SRVR50D4R2 is a PowerQUICC I communications processor from NXP Semiconductors (formerly Freescale). It integrates a 32-bit Power Architecture core running at 50MHz with a Communications Processor Module (CPM) containing 4 SCCs, 2 SMCs, SPI, and I2C. The MPC860SR variant supports ATM over UTOPIA in addition to 10\/100 Ethernet. Packaged in a 357-pin TBGA, this device is now obsolete but was widely deployed in networking and communications equipment.<\/p>\n

The MPC860SR variant adds ATM UTOPIA support alongside 10\/100 Ethernet, making it suitable for multi-protocol networking equipment. With 4 SCCs, 2 SMCs, SPI, and I2C, the CPM offloads serial communication processing from the core, enabling efficient data plane operation. This device is now obsolete but was extensively used in telecom and networking infrastructure.","working_principle":"The MPC860SRVR50D4R2 uses a dual-processor architecture: the main Power Architecture core handles the control plane (OS, routing protocols, management), while the Communications Processor Module (CPM) with its own RISC core handles the data plane (serial I\/O, protocol processing). The CPM executes microcode in 8 KB dual-port SRAM, managing 4 SCCs that can independently handle Ethernet, HDLC, UART, or transparent mode protocols. For ATM, the UTOPIA interface connects to external PHY devices, with the CPM performing cell segmentation and reassembly (SAR). The 8-bank memory controller supports glueless interface to DRAM, SRAM, EPROM, and Flash. The core's MMU provides virtual memory support for embedded Linux or VxWorks operating systems. The PCMCIA controller supports two sockets for expansion cards.","pin_description":"\n
