Table 2 summarizes the functions of the blocks present on the MPC5646C.

Table 2. MPC5646C series block summary

Block

Function

Analog-to-digital converter (ADC) Converts analog voltages to digital values

Boot assist module (BAM)

A block of read-only memory containing VLE code which is executed according

to the boot mode of the device

Clock monitor unit (CMU)

Monitors clock source (internal and external) integrity

Cross triggering unit (CTU)

Enables synchronization of ADC conversions with a timer event from the eMIOS

or from the PIT

Cryptographic Security Engine

(CSE)

Supports the encoding and decoding of any kind of data

Crossbar (XBAR) switch

Supports simultaneous connections between two master ports and three slave

ports. The crossbar supports a 32-bit address bus width and a 64-bit data bus

width

DMA Channel Multiplexer

(DMAMUX)

Allows to route DMA sources (called slots) to DMA channels

Deserial serial peripheral interface Provides a synchronous serial interface for communication with external devices

(DSPI)

Error Correction Status Module

(ECSM)

Provides a myriad of miscellaneous control functions for the device including

program-visible information about configuration and revision levels, a reset status

register, wakeup control for exiting sleep modes, and optional features such as

information on memory errors reported by error-correcting codes

Enhanced Direct Memory Access Performs complex data transfers with minimal intervention from a host processor

(eDMA)

via “n” programmable channels.

Enhanced modular input output Provides the functionality to generate or measure events

system (eMIOS)

Flash memory

Provides non-volatile storage for program code, constants and variables

FlexCAN (controller area network) Supports the standard CAN communications protocol

FMPLL (frequency-modulated

phase-locked loop)

Generates high-speed system clocks and supports programmable frequency

modulation

FlexRay (FlexRay communication Provides high-speed distributed control for advanced automotive applications

controller)

Fast Ethernet Controller (FEC)

Ethernet Media Access Controller (MAC) designed to support both 10 and 100

Mbps Ethernet/IEEE 802.3 networks

Internal multiplexer (IMUX) SIUL Allows flexible mapping of peripheral interface on the different pins of the device

subblock

Inter-integrated circuit (I2C™) bus A two wire bidirectional serial bus that provides a simple and efficient method of

data exchange between devices

Interrupt controller (INTC)

Provides priority-based preemptive scheduling of interrupt requests for both

e200z0h and e200z4d cores

JTAG controller

Provides the means to test chip functionality and connectivity while remaining

transparent to system logic when not in test mode
