MCF5275LCVM166(NXP Semiconductors) 説明
Additional information about the MCF5275LCVM166: The MCF5275 family is a highly integrated implementation of the ColdFire family of reduced instruction set computing (RISC) microprocessors. This document describes pertinent features and functions characteristics of the MCF5275 family. The MCF5275 family includes the MCF5275, MCF5275L, MCF5274 and MCF5274L microprocessors. The differences between these parts are summarized in Table 1. This document is written from the perspective of the MCF5275 and unless otherwise noted, the information applies also to the MCF5275L, MCF5274 and MCF5274L. The MCF5275 family delivers a new level of performance and integration on the popular version 2 ColdFire core with up to 159 (Dhrystone 2.1) MIPS @ 166MHz. These highly integrated microprocessors build upon the widely used peripheral mix on the popular MCF5272 ColdFire microprocessor (10/100 Mbps Ethernet MAC and USB device) by adding a second 10/100 Mbps Ethernet MAC (MCF5274 and MCF5275) and hardware encryption (MCF5275L and MCF5275).In addition, the MCF5275 family features an enhanced multiply accumulate unit (EMAC), large on-chip memory (64 Kbytes SRAM, 16 Kbytes configurable cache), and a 16-bit DDR SDRAM memory controller. These devices are ideal for cost-sensitive applications requiring significant control processing for file management, connectivity, data buffering, and user interface, as well as signal processing in a variety of key markets such as security, imaging, networking, gaming, and medical. This leading package of integration and high performance allows fast time to market through easy code reuse and extensive third party tool support.
