NXP Semiconductors Microprocessors MPC862TCVR66B

The MPC862TCVR66B is a member of the MPC862/857T/857DSL family of microprocessors from Freescale Semiconductor, designed for a variety of controller applications and communications systems. It features a single-issue, 32-bit PowerPC core with branch prediction and supports both 4 Kbyte and 8 Kbyte data caches, as well as 4 Kbyte and 16 Kbyte instruction caches, depending on the specific variant. The device includes advanced memory management capabilities with a 32-entry TLB and supports multiple page sizes. This microprocessor offers enhanced ATM functionality, including improved operation, administration, and maintenance (OAM) support, as well as ATM port-to-port switching without the need for RAM-based microcode. It supports simultaneous MII (10/100Base-T) and UTOPIA operation, making it suitable for high-performance networking applications. The integrated memory controller supports various memory types and configurations, providing flexibility for system design. Engineers considering the MPC862TCVR66B should evaluate its capabilities in relation to their specific application requirements, particularly in networking and communications contexts.
