Block summary

Table 2 summarizes the functions of the blocks present on the MPC5634M series microcontrollers.

Pinout and signal description

This section contains the pinouts for all production packages for the MPC5634M family of devices. Please note the following:

•

Pins labeled “NC” are to be left unconnected. Any connection to an external circuit or voltage may cause unpredictable

device behavior or damage.

•

Pins labeled “NIC” have no internal connection.

Block

Function

e200z3 core

Executes programs and interrupt handlers.

Flash memory

Provides storage for program code, constants, and variables

RAM (random-access memory)

Provides storage for program code, constants, and variables

Calibration bus

Transfers data across the crossbar switch to/from peripherals attached to the

VertiCal connector

DMA (direct memory access)

Performs complex data movements with minimal intervention from the core

DSPI (deserial serial peripheral interface)

Provides a synchronous serial interface for communication with external

devices

eMIOS (enhanced modular input-output system) Provides the functionality to generate or measure events

eQADC (enhanced queued analog-to-digital

converter)

Provides accurate and fast conversions for a wide range of applications

eSCI (serial communication interface)

Allows asynchronous serial communications with peripheral devices and

other microcontroller units

eTPU (enhanced time processor unit)

Processes real-time input events, performs output waveform generation, and

accesses shared data without host intervention

FlexCAN (controller area network)

Supports the standard CAN communications protocol

FMPLL (frequency-modulated phase-locked

loop)

Generates high-speed system clocks and supports the programmable

frequency modulation of these clocks

INTC (interrupt controller)

Provides priority-based preemptive scheduling of interrupt requests

JTAG controller

Provides the means to test chip functionality and connectivity while remaining

transparent to system logic when not in test mode

NPC (Nexus Port Controller)

Provides real-time development support capabilities in compliance with the

IEEE-ISTO 5001-2003 standard

PIT (peripheral interrupt timer)

Produces periodic interrupts and triggers

Temperature sensor

Provides the temperature of the device as an analog value

SWT (Software Watchdog Timer)

Provides protection from runaway code

STM (System Timer Module)

Timer providing a set of output compare events to support AutoSAR and

operating system tasks
