Product details
Overview
MCF5275CVM166 from Freescale Semiconductor is a ColdFire® V2 RISC microprocessor delivering 159 Dhrystone 2.1 MIPS at 166 MHz, featuring dual 10/100 Mbps Ethernet MACs, hardware encryption, 64 KB on-chip SRAM, 16 KB configurable cache, and a 16-bit DDR SDRAM controller in a 256-ball MAPBGA package. It targets embedded networking and security applications requiring high integration and deterministic real-time control.
For engineers reviewing the MCF5275CVM166 datasheet, MCF5275CVM166 pinout, MCF5275CVM166 application, or MCF5275CVM166 equivalent, key selection criteria include dual-FEC support, DDR SDRAM interface timing compliance, hardware crypto acceleration (AES/SHA), ColdFire V2 core instruction set compatibility, and industrial temperature range (–40°C to +85°C) operation.
Technical Context
The MCF5275CVM166 implements the ColdFire V2 core with an enhanced multiply-accumulate unit (EMAC) optimized for signal processing tasks. Its memory subsystem integrates a 16-bit DDR SDRAM controller supporting SSTL-2.5V or SSTL-3.3V I/O, plus 64 KB of on-die SRAM and 16 KB of configurable instruction/data cache.
Dual Fast Ethernet Controllers (FEC0 and FEC1) operate independently in MII mode with full 18-signal MII compliance, including dedicated MDIO/MDC management interfaces and separate TX/RX clock domains. Hardware encryption includes MDHA (SHA-1/SHA-256), SKHA (AES-128/192/256), and RNGA modules accessible via memory-mapped registers.
Key Specifications
