Overview

PowerPC instruction set. This family of parts contains many new features coupled with high performance

CMOS technology to provide significant performance improvement over the MPC565.

The MPC5553 of the MPC5500 family has two levels of memory hierarchy. The fastest accesses are to the

8-kilobyte unified cache. The next level in the hierarchy contains the 64-kilobyte on-chip internal SRAM

and 1.5 Mbyte internal Flash memory. Both the internal SRAM and the Flash memory can hold

instructions and data. The external bus interface has been designed to support most of the standard

memories used with the MPC5xx family.

The complex I/O timer functions of the MPC5500 family are performed by an enhanced time processor

unit engine (eTPU). The eTPU engine controls 32 hardware channels. The eTPU has been enhanced over

the TPU by providing 24-bit timers, double action hardware channels, variable number of parameters per

channel, angle clock hardware, and additional control and arithmetic instructions. The eTPU can be

programmed using a high-level programming language.

The less complex timer functions of the MPC5500 family are performed by the enhanced modular

input/output system (eMIOS). The eMIOS’ 24 hardware channels are capable of single action, double

action, pulse width modulation (PWM), and modulus counter operation. Motor control capabilities include

edge-aligned and center-aligned PWM.

Off-chip communication is performed by a suite of serial protocols including controller area networks

(FlexCANs), enhanced deserial/serial peripheral interfaces (DSPI), and enhanced serial communications

interfaces (eSCIs). The DSPIs support pin reduction through hardware serialization and deserialization of

timer channels and general-purpose input/output (GPIO) signals.

The MCU of the MPC5553 has an on-chip 40-channel enhanced queued dual analog-to-digital converter

(eQADC).

The system integration unit (SIU) performs several chip-wide configuration functions. Pad configuration

and general-purpose input and output (GPIO) are controlled from the SIU. External interrupts and reset

control are also found in the SIU. The internal multiplexer submodule (SIU_DISR) provides multiplexing

of eQADC trigger sources, daisy chaining the DSPIs and external interrupt signal multiplexing.
