Feature Overview

The MCF52235 family includes the following features:

•

Version 2 ColdFire variable-length RISC processor core

— Static operation

— 32-bit address and data paths on-chip

— Up to 60 MHz processor core frequency

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

— Implements ColdFire ISA_A with extensions to support the user stack pointer register and four new instructions

for improved bit processing (ISA_A+)

— Enhanced Multiply-Accumulate (EMAC) unit with 32-bit accumulator to support 16

× 16 → 32 or 32 × 32 → 32

operations

— Cryptography Acceleration Unit (CAU)

–

Tightly-coupled coprocessor to accelerate software-based encryption and message digest functions

–

FIPS-140 compliant random number generator

— Support for DES, 3DES, AES, MD5, and SHA-1 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 (DEBUG_B+)

— Real time debug support, with six hardware breakpoints (4 PC, 1 address and 1 data) that can be configured into

a 1- or 2-level trigger

•

On-chip memories

— Up to 32 Kbytes of dual-ported SRAM on CPU internal bus, supporting core and DMA access with standby power

supply support

— Up to 256 Kbytes of interleaved Flash memory supporting 2-1-1-1 accesses

•

Power management

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

— 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)

— 10/100 BaseT/TX capability, half duplex or full duplex

— On-chip transmit and receive FIFOs

— Built-in dedicated DMA controller

— Memory-based flexible descriptor rings

•

On-chip Ethernet Transceiver (EPHY)

— Digital adaptive equalization

— Supports auto-negotiation

— Baseline wander correction

— Full-/Half-duplex support in all modes

— Loopback modes

— Supports MDIO preamble suppression

— Jumbo packet

•

FlexCAN 2.0B module
