Entry-level 32-bit MCF520x and MCF521x embedded controllers simplify migration for cost-sensitive applications
Freescale Semiconductor is enhancing its 32-bit leadership with the introduction of two ColdFire® device families. The MCF520x and MCF521x families ease the migration to 32-bit performance for applications that require low power consumption and flexible integration at an affordable price point.
Designed for a wide variety of control applications, including factory automation, lighting control, security and retail point-of-sale scanners, the MCF520x and MCF521x devices address the need for high-performance, cost-effective, low-power embedded connectivity.
Low-power devices deliver high performance
With a typical current draw of less than 1mA/MHz, the MCF520x and MCF521x families specifically address the need for high-performance, low-power embedded connectivity in industrial control applications.
The families are the first ColdFire products to offer integrated distributed clocking and low-power divider functionality to scale the central processing unit (CPU) below 1MHz without going into shutdown mode. Freescale has also minimized leakage and focused on packaging enhancements to optimize power consumption without sacrificing performance.
For embedded connectivity applications in which performance is the driving factor, the MCF520x microprocessor (MPU) family delivers as much as 159 million instructions per second (MIPS) at suggested resale pricing less than $5 (USD). The MCF520x family offers an enhanced multiply-accumulate (eMAC) module and instruction/data cache with an optional Ethernet controller. The devices feature a flexible memory controller, flash, static random access memory (SRAM) and a choice of single data rate (SDR) or double data rate (DDR) synchronous dynamic random access memory (SDRAM) memory.
The MCF521x MCU family is ideal for control applications that require a high level of integration and in which space, system costs and power consumption are at a premium. These devices offer up to 256KB of integrated flash memory, a 12-bit analog-to-digital converter (ADC), a MAC module for digital signal processing (DSP) functionality and an optional controller area network (CAN) module.
Both families are code-compatible with the Freescale ColdFire product portfolio and use the high-performance V2 ColdFire core with on-chip memory, direct memory access (DMA) controller, general purpose I/Os and connectivity peripherals - including universal asynchronous receiver/transmitters (UARTs), inter-IC bus (I2C) interface and queued serial peripheral interface (QSPI).
Comprehensive development support
Freescale is committed to helping customers introduce products to market easier and faster through direct development support and services. Freescale also offers assistance with migration from the 68K family via free translators and tools.
The MCF520x and MCF521x processor evaluation boards ship with a fully licensed, complimentary Special Edition of the CodeWarrior Development Studio for ColdFire Architectures. The Special Edition is code-size limited and includes a ColdFire optimizing compiler designed for maximizing performance and generating compact code. The Special Edition is ideal for cost-sensitive solutions and eliminates time restrictions during evaluation of ColdFire processors. Developers who require more comprehensive tools can purchase Standard and Professional Editions of the CodeWarrior Development Studio.
Freescale offers comprehensive software and tools solutions through partnerships with world-class suppliers, including Green Hills, MQX Embedded, Wind River and Accelerated Technology, as well as many other independent suppliers. Customers also have access to full open source software solutions, as well as third-party off-the-shelf boards.
