MCF523x Integrated
Microprocessor
Hardware Specification
by: Microcontroller Solutions Group
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.
