MCF5272 Integrated
Microprocessor Product Brief
This document provides an overview of the MCF5272 microprocessor features, including the
major functional components.
1.1 Features
A block diagram of the MCF5272 is shown in Figure 1. The main features are as follows:
⢠Static Version 2 ColdFire variable-length RISC processor
â 32-bit address and data path on-chip
â 66-MHz processor core and bus frequency
â Sixteen general-purpose 32-bit data and address registers
â Multiply-accumulate unit (MAC) for DSP and fast multiply operations
â 63 Dhrystone 2.1 MIPS at 66 MHz
⢠On-chip memories
â 4-Kbyte SRAM on CPU internal bus
â 16-Kbyte ROM on CPU internal bus
â 1-Kbyte instruction cache
⢠Power management
â Fully-static operation with processor sleep and whole-chip stop modes
â Very rapid response to interrupts from the low-power sleep mode (wake-up
feature)
â Clock enable/disable for each peripheral when not used
â Software-controlled disable of external clock input for virtually zero power
consumption (low-power stop mode)
⢠Two universal asynchronous/synchronous receiver transmitters (UARTs)
â Full-duplex operation
â Based on MC68681 dual-UART (DUART) programming model
â Flexible baud rate generator
â Modem control signals available (CTS and RTS)
â Processor interrupt and wake-up capability
â Enhanced Tx, Rx FIFOs, 24 bytes each
