Device blocks

MPC5604B/C Microcontroller Data Sheet, Rev. 4

Freescale Semiconductor

Periodic interrupt timer (PIT)

Produces periodic interrupts and triggers

Power control unit (PCU)

Reduces the overall power consumption by disconnecting parts of the device

from the power supply via a power switching device; device components are

grouped into sections called “power domains” which are controlled by the PCU

Real-time counter (RTC)

A free running counter used for time keeping applications, the RTC can be

configured to generate an interrupt at a predefined interval independent of the

mode of operation (run mode or low-power mode)

Reset generation module (RGM)

Centralizes reset sources and manages the device reset sequence of the device

Static random-access memory

(SRAM)

Provides storage for program code, constants, and variables

System integration unit (SIU)

Provides control over all the electrical pad controls and up 32 ports with 16 bits

of bidirectional, general-purpose input and output signals and supports up to 32

external interrupts with trigger event configuration

System status configuration

module (SSCM)

Provides system configuration and status data (such as memory size and status,

device mode and security status), device identification data, debug status port

enable and selection, and bus and peripheral abort enable/disable

System timer module (STM)

Provides a set of output compare events to support AUTOSAR and operating

system tasks

System watchdog timer (SWT)

Provides protection from runaway code

Test control unit (TCU)

An extension of the JTAG controller module, the TCU provides the means to test

chip functionality and connectivity while remaining transparent to system logic

when not in test mode.
