Overview

This chapter provides an overview of the microprocessor features, including the major functional components.



Key Features

A block diagram of the MCF528x and MCF521x is shown in Figure 1-1. The main features are as follows:

• Static Version 2 ColdFire variable-length RISC processor

   — Static operation

   — On-chip 32-bit address and data path

   — Processor core and bus frequency up to 80 MHz

   — Sixteen general-purpose 32-bit data and address registers

   — ColdFire ISA_A with extensions to support the user stack pointer register, and four new instructions for improved bit processing

   — Enhanced Multiply-Accumulate (EMAC) unit with four 48-bit accumulators to support 32-bit signal processing algorithms

   — Illegal instruction decode that allows for 68K emulation support

• System debug support

   — Real-time trace for determining dynamic execution path

   — Background debug mode (BDM) for in-circuit debugging

   — Real time debug support, with one user-visible hardware breakpoint register (PC and address with optional data) that can be configured into a 1- or 2-level trigger

• On-chip memories

   — 2-Kbyte cache, configurable as instruction-only, data-only, or split I-/D-cache

   — 64-Kbyte dual-ported SRAM on CPU internal bus, accessible by core and non-core bus masters

      (e.g., DMA, FEC) with standby power supply support

   — 512 Kbytes of interleaved Flash memory supporting 2-1-1-1 accesses

      (256 Kbytes on the MCF5281 and MCF5214, no Flash on MCF5280)

   – This product incorporates SuperFlash® technology licensed from SST.

• Power management

   — Fully-static operation with processor sleep and whole chip stop modes

   — Very rapid response to interrupts from the low-power sleep mode (wake-up feature)

   — Clock enable/disable for each peripheral when not used

• Fast Ethernet Controller (FEC) (not available on the MCF5214 and MCF5216)

   — 10BaseT capability, half- or full-duplex

   — 100BaseT capability, half- or limited-throughput full-duplex

   — On-chip transmit and receive FIFOs

   — Built-in dedicated DMA controller

   — Memory-based flexible descriptor rings

   — Media-independent interface (MII) to transceiver (PHY)

• FlexCAN 2.0B Module

   — Includes all existing features of the Freescale TouCAN module

   — Full implementation of the CAN protocol specification version 2.0B

      – Standard data and remote frames (up to 109 bits long)

      – Extended data and remote frames (up to 127 bits long)

      – 0–8 bytes data length

      – Programmable bit rate up to 1 Mbit/sec

   — Up to 16 message buffers (MBs)

      – Configurable as receive (Rx) or transmit (Tx)

      – Support standard and extended messages

   — Unused message buffer (MB) space can be used as general-purpose RAM space

   — Listen-only mode capability

   — Content-related addressing

   — No read/write semaphores

   — Three programmable mask registers

      – Global (for MBs 0-13)

      – Special for MB14

      – Special for MB15

   — Programmable transmit-first scheme: lowest ID or lowest buffer number

   — “Time stamp” based on 16-bit free-running timer

   — Global network time, synchronized by a specific message

   — Programmable I/O modes

   — Maskable interrupts

• Three universal asynchronous/synchronous receiver transmitters (UARTs)

   — 16-bit divider for clock generation

   — Interrupt control logic

   — Maskable interrupts

   — DMA support

   — Data formats can be 5, 6, 7, or 8 bits with even, odd, or no parity

   — Up to 2 stop bits in 1/16 increments

   — Error-detection capabilities

   — Modem support includes request-to-send (URTS) and clear-to-send (UCTS) lines for two UARTs

   — Transmit and receive FIFO buffers

• I2C module

   — Interchip bus interface for EEPROMs, LCD controllers, A/D converters, and keypads

   — Fully compatible with industry-standard I2C bus

   — Master or slave modes support multiple masters

   — Automatic interrupt generation with programmable level

• Queued serial peripheral interface (QSPI)

   — Full-duplex, three-wire synchronous transfers

   — Up to four chip selects available

   — Master mode operation only

   — Programmable master bit rates

   — Up to 16 pre-programmed transfers

• Queued analog-to-digital converter (QADC)

   — 8 direct, or up to 18 multiplexed, analog input channels

   — 10-bit resolution +/- 2 counts accuracy

   — Minimum 7 μS conversion time

   — Internal sample and hold

   — Programmable input sample time for various source impedances

   — Two conversion command queues with a total of 64 entries

   — Sub-queues possible using pause mechanism

   — Queue complete and pause software interrupts available on both queues

   — Queue pointers indicate current location for each queue

   — Automated queue modes initiated by:

      – External edge trigger and gated trigger

      – Periodic/interval timer, within QADC module [Queue 1 and 2]

      – Software command

   — Single-scan or continuous-scan of queues

   — Output data readable in three formats:

      – Right-justified unsigned

      – Left-justified signed

      – Left-justified unsigned

   — Unused analog channels can be used as digital I/O

   — Low pin-count configuration implemented
