NXP Semiconductors MPC565MZP56R2

Overview

MPC565MZP56R2 from Freescale Semiconductor is a 32-bit PowerPC RISC microcontroller designed for automotive and industrial real-time control systems, featuring a floating-point unit (FPU), 1 Mbyte UC3F Flash memory, 36 Kbytes CALRAM, three TouCAN 2.0B modules, and MIOS14 with real-time clock submodule - deployed in engine control units (ECUs) requiring deterministic timing and high-temperature operation.

For engineers reviewing the MPC565MZP56R2 datasheet, MPC565MZP56R2 pinout, MPC565MZP56R2 application, or MPC565MZP56R2 equivalent, key selection criteria include its -40°C to 125°C operating range, 40 MHz core frequency, 5-V tolerant I/O, Nexus Class 3 debug support, and TPU3-based timing precision for multi-sensor actuator coordination.

Technical Context

The MPC565MZP56R2 implements a fully static PowerPC integer core with FPU and burst buffer controller (BBC), supporting four power-saving modes (doze, sleep, deep-sleep, power-down) and exception vector relocation to internal Flash, SRAM, or external memory. Its USIU integrates clock synthesizer, enhanced interrupt controller (48 total vectors), and dual-mapped Flash for development flexibility.

Memory architecture includes two 512-Kbyte UC3F Flash modules with 100,000-cycle endurance and 100-year data retention at 25°C, plus 36 Kbytes of static CALRAM split into 32-Kbyte CALRAM A and 4-Kbyte CALRAM B - both with keep-alive power via dedicated VDDSRAM pins and overlay access capability across 16 regions.

FAQ

What is the maximum operating frequency of the MPC565MZP56R2?

The MPC565MZP56R2 operates at a maximum frequency of 40 MHz under standard conditions. While some MPC566 variants support 56 MHz, the MPC565MZP56R2 is rated for 40 MHz operation only - confirmed in the Freescale MPC565PB/D Product Brief Rev. 3, Section 1.2.15. This frequency is guaranteed across the full -40°C to 125°C ambient range with proper decoupling and power supply regulation.

Does the MPC565MZP56R2 support code compression like the MPC566?

No, the MPC565MZP56R2 does not support code compression. Table 1 in the MPC565/MPC566 Product Brief explicitly states "Code compression not supported" for MPC565, whereas MPC566 supports it. The MPC565MZP56R2 uses the base MPC565 silicon configuration - meaning all firmware must fit within the 1 Mbyte UC3F Flash without compression, unlike the MPC566MZP56R2 which can reduce effective code size by 50–60%.

How many CAN controllers does the MPC565MZP56R2 integrate, and what version do they implement?

The MPC565MZP56R2 integrates three TouCAN modules (TouCAN_A, TouCAN_B, and TouCAN_C), each compliant with CAN 2.0B specification. As documented in Section 1.2.13, these controllers support 16 message buffers per module, programmable loopback for self-test, and low-power sleep mode with wake-up on bus activity - enabling robust, fault-tolerant communication in distributed automotive networks.

What is the purpose of the VDDSRAM1, VDDSRAM2, and VDDSRAM3 pins on the MPC565MZP56R2?

VDDSRAM1 powers the 32-Kbyte CALRAM A module during keep-alive mode; VDDSRAM2 powers the 4-Kbyte CALRAM B; and VDDSRAM3 powers both DPTRAM modules (6 Kbyte + 4 Kbyte) and the BBC's 4-Kbyte DECRAM. These dedicated rails maintain SRAM contents during system power-down - preserving calibration data, timing context, and microcode - as detailed in Section 3 of the MPC565PB/D document.

Is the MPC565MZP56R2 pin-compatible with the MPC555 series?

No, the MPC565MZP56R2 is not pin-compatible with the MPC555 series. Although both belong to the MPC500 family, the MPC565 introduces new peripherals (READI, DLCMD2, MIOS14, TouCAN_C), revised power domains (QVDDL/NVDDL), and expanded pin functions - resulting in different pin assignments and electrical behavior. Figure 4 (MPC565 Pinout Diagram) confirms distinct ball mapping versus MPC555 documentation.
