1.2.6
Power Management
The MCF52235 incorporates several low power modes of operation which are entered under program
control and exited by several external trigger events. An integrated power-on reset (POR) circuit monitors
the input supply and forces an MCU reset as the supply voltage rises. The low voltage detector (LVD)
monitors the supply voltage and is configurable to force a reset or interrupt condition if it falls below the
LVD trip point.
1.2.7
Fast Ethernet Controller (FEC)
The integrated Fast Ethernet Controller (FEC) performs the full set of IEEE 802.3/Ethernet CSMA/CD
media access control and channel interface functions. The FEC connects through the on-chip transceiver
(ePHY) which provides the physical layer interface.
1.2.8
Ethernet Physical Interface (ePHY)
The ePHY is an IEEE 802.3 compliant 10/100 Ethernet physical transceiver. The ePHY can be configured
to support 10BASE-T or 100BASE-TX applications. The ePHY is configurable via internal registers.
There are five basic modes of operation for the ePHY:
Power down/initialization
Auto-negotiate
10BASE-T
100BASE-TX
Low-power
1.2.9
Cryptography Acceleration Unit
The MCF52235 device incorporates two hardware accelerators for cryptographic functions. First, the
CAU is a coprocessor tightly-coupled to the V2 ColdFire core that implements a set of specialized
operations to increase the throughput of software-based encryption and message digest functions,
specifically the DES, 3DES, AES, MD5 and SHA-1 algorithms. Second, a random number generator
provides FIPS-140 compliant 32-bit values to security processing routines. Both modules supply critical
acceleration to software-based cryptographic algorithms at a minimal hardware cost.
1.2.10 FlexCAN
The FlexCAN module is a communication controller implementing version 2.0 of the CAN protocol parts
A and B. The CAN protocol can be used as an industrial control serial data bus, meeting the specific
requirements of reliable operation in a harsh EMI environment with high bandwidth. This instantiation of
FlexCAN has 16 message buffers.
