MCF5253VM140J - Freescale Semiconductor

Overview

Anchored by the Version 2 ColdFire® core, the

MCF5253 is an excellent general-purpose,

cost-effective system controller with over 125

Dhrystone 2.1 MIPS of performance at 140

MHz. The MCF5253 is a unique addition to

the ColdFire family because it features two

CAN modules, the largest SRAM block in the

portfolio at 128K and is the first to offer high-

speed USB On-the-Go (OTG) with integrated

Physical Layer (PHY). Other features include

a dedicated advanced technology attachment

(ATA) hard disk interface, real-time clock

(RTC) and an enhanced multiply-accumulate

(eMAC) unit which provides DSP capabilities.

Low-power management features include a

flexible phase-lock-loop (PLL) with power-

down mode and dynamic clock switching.

Freescale’s added integration empowers

customers to reduce the number of system

components that lowers their development

costs and facilitates rapid time to market. The

MCF5253 is suitable for numerous consumer

and industrial applications including point-

of-sale, Voice-over IP (VoIP) and medical

instrumentation.
