NXP Semiconductors MPC564CVR40

Overview

MPC564CVR40 from Freescale Semiconductor is a 32-bit PowerPC-based microcontroller designed for automotive powertrain and chassis control systems, featuring a 40 MHz core clock, 512 KB on-chip CDR3 Flash EEPROM (MPC564-specific), 32 KB CALRAM, three TouCAN 2.0B controllers, and dual QADC64E modules for high-precision analog acquisition in engine management units.

For engineers reviewing the MPC564CVR40 datasheet, MPC564CVR40 pinout, MPC564CVR40 application, or MPC564CVR40 equivalent, this device requires attention to its Nexus Class 3 debug interface, peripheral pin multiplexing (PPM) configuration, TPU3 timer subsystem, and voltage domain compatibility (2.6 V core / 5 V I/O) when integrating into ASIL-B–capable ECU designs.

Technical Context

The MPC564CVR40 implements the PowerPC Book E architecture with a RISC MCU Central Processing Unit (RCPU), Unified System Interface Unit (USIU), and Burst Buffer Controller (BBC) supporting instruction decompression. It integrates two Time Processor Units (TPU3) for real-time signal capture and generation, and a flexible Memory Protection Unit enabling secure partitioning of Flash and RAM regions.

Its integrated I/O system includes 22-channel Modular I/O System (MIOS14), two enhanced queued ADCs (QADC64E) with up to 16-bit resolution and 1 µs conversion time, and three independent CAN 2.0B controllers with message buffering and error handling-configured via dedicated TouCAN modules rather than shared peripheral buses.

Key Specifications

Pinout & Package

The MPC564CVR40 is housed in a 208-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with dedicated power/ground pairs per I/O bank and separate 2.6 V core supply pins.

The MPC564 belongs to Freescale's MPC56x family of PowerPC-based automotive microcontrollers, engineered specifically for ASIL-B–compliant powertrain and chassis control applications demanding high computational throughput, deterministic timing, and robust fault containment.

FAQ

What is the maximum operating frequency of the MPC564CVR40?

The MPC564CVR40 operates at a maximum core clock frequency of 40 MHz. This frequency defines the instruction execution rate, timer resolution, and real-time interrupt response capability. The actual system clock is derived from an external crystal or oscillator through the on-chip PLL, and the 40 MHz specification reflects the guaranteed performance under validated voltage (2.6 V core) and temperature (–40°C to 125°C) conditions specified in Freescale's characterization data for the MPC564CVR40.

Does the MPC564CVR40 include on-chip Flash memory, and what type is it?

Yes, the MPC564CVR40 integrates 512 KB of on-chip CDR3 Flash EEPROM memory - a Freescale-specific technology enabling both program storage and EEPROM-like data retention without external components. Unlike standard Flash, CDR3 supports byte-level erase and write operations, making it suitable for storing calibration tables, fault logs, and adaptive learning parameters in automotive ECUs. This feature is explicitly confirmed for the MPC564 variant in the MPC561/MPC563 Reference Manual Rev. 1.2.

How many CAN controllers does the MPC564CVR40 support, and what protocol version?

The MPC564CVR40 supports three independent CAN 2.0B controllers implemented as TouCAN modules. Each module complies fully with ISO 11898-1, supporting both standard (11-bit) and extended (29-bit) identifier frames, bit rates up to 1 Mbps, and built-in message filtering and error confinement. These controllers operate autonomously with dedicated message RAM and do not share bus arbitration logic - a key differentiator from earlier MPC5xx derivatives.

What debug interface does the MPC564CVR40 provide, and what level of visibility does it offer?

The MPC564CVR40 features a Nexus Class 3 debug port compliant with IEEE-ISTO 5001™, providing non-intrusive real-time trace, hardware breakpoints, data watchpoints, and program flow analysis. This interface enables cycle-accurate profiling, exception tracing, and memory access monitoring without halting CPU execution - essential for validating timing-critical automotive control loops. The Nexus implementation in MPC564CVR40 includes dedicated trace buffer support and timestamping, as documented in the MPC561/MPC563 Reference Manual.

Is the MPC564CVR40 pin-compatible with other members of the MPC56x family?

No, the MPC564CVR40 is not universally pin-compatible across the MPC56x family. While it shares the 208-pin LQFP package with MPC563CVR40 and MPC562CVR40, differences in peripheral pin assignments - particularly for QADC64E analog inputs, MIOS14 channel routing, and TouCAN signal placement - require board-level validation. The MPC564CVR40 datasheet and signal multiplexing tables confirm unique pin mappings for its expanded Flash and dual QADC resources, meaning direct PCB substitution is not supported without schematic and layout review.
