1 / 46 page Freescale Semiconductor Hardware Specification Document Number: MCF5235EC Rev. 2, 08/2006 Contents © Freescale Semiconductor, Inc., 2006. All rights reserved. The MCF523x is a family of highly-integrated 32-bit microcontrollers based on the V2 ColdFire microarchitecture. Featuring a 16 or 32 channel eTPU, 64 Kbytes of internal SRAM, a 2-bank SDRAM controller, four 32-bit timers with dedicated DMA, a 4 channel DMA controller, up to 2 CAN modules, 3 UARTs and a queued SPI, the MCF523x family has been designed for general purpose industrial control applications. It is also a high-performance upgrade for users of the MC68332. This document provides an overview of the MCF523x microcontroller family, as well as detailed descriptions of the mechanical and electrical characteristics of the devices. The MCF523x family is based on the Version 2 ColdFire reduced instruction set computing (RISC) microarchitecture operating at a core frequency of up to 150 MHz and bus frequency up to 75 MHz. 1 MCF523x Family Configurations . . . . . . . . . . . . . . . . . . . 2 2 Block Diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 3 Features . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 4 Signal Descriptions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 5 Design Recommendations . . . . . . . . . . . . . . . . . . . . . . . 9 6 Mechanicals/Pinouts and Part Numbers . . . . . . . . . . . . 14 7 Preliminary Electrical Characteristics . . . . . . . . . . . . . . 23 8 Documentation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 44 9 Document Revision History . . . . . . . . . . . . . . . . . . . . . . 44 MCF523x Integrated Microprocessor Hardware Specification by: Microcontroller Division |
