NXP 32 Bit Microcontrollers MCU Embedded Processors And Controllers MCF5282CVM66

MCF5282CVM66 NXP MAPBGA-256 32-bit Microcontrollers - MCU Embedded Processors & Controllers

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
