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