Description

This microcontroller is a 32-bit system-on-chip (SoC) device intended for use in mid-range engine control and automotive transmission control applications. It is compatible with devices in Freescale’s MPC5600 family and offers performance and capabilities beyond the MPC5632M devices. The microcontroller’s e200z4 host processor core is built on the Power Architecture® technology and designed specifically for embedded applications. In addition to the Power Architecture technology, this core supports instructions for digital signal processing (DSP). The device has two levels of memory hierarchy consisting of 8 KB of instruction cache, backed by a 128 KB on-chip SRAM and a 2 MB internal flash memory. For development, the device includes a calibration bus that is accessible only when using the Freescale VertiCal Calibration System.

• Memory organization including 2 MB on-chip flash memory with ECC and read-while-write (RWW), 128 KB on-chip SRAM with standby functionality (32 KB) and ECC, 8 KB instruction cache (with line locking) configurable as 2- or 4-way, and 14 + 3 KB eTPU code and data RAM.
• Fail Safe Protection features such as a 16-entry Memory Protection Unit (MPU), CRC unit with 3 submodules, and a junction temperature sensor.
• Interrupt capabilities with a configurable interrupt controller (INTC) with non-maskable interrupt (NMI) and a 64-channel eDMA.
• Serial channels including 3 eSCI modules, 3 DSPI modules (2 of which support downstream Micro Second Channel [MSC]), 3 FlexCAN modules with 64 message buffers each, and 1 FlexRay module (V2.1) up to 10 Mbit/s w/dual or single channel, 128 message objects, ECC.
• Other features include 1 eMIOS with 24 unified channels, 1 eTPU2 (second generation eTPU) with 32 standard channels and a reaction module (6 channels with 3 outputs per channel), 2 enhanced queued analog-to-digital converters (eQADCs) with forty 12-bit input channels (multiplexed on 2 ADCs); expandable to 56 channels with external multiplexers, on-chip CAN/SCI Bootstrap loader with Boot Assist Module (BAM), Nexus: Class 3+ for core; Class 1 for eTPU, JTAG (5-pin), Development Trigger Semaphore (DTS) with EVTO pin for communication with external tool, and clock generation including on-chip 4–40 MHz main oscillator and on-chip FMPLL (frequency-modulated phase-locked loop).
• The microcontroller has up to 112 general purpose I/O lines that are individually programmable as input, output or special function with programmable threshold (hysteresis). It also supports power reduction modes: slow, stop, and standby, and has a flexible supply scheme including 5 V single supply with external ballast and multiple external supply: 5 V, 3.3 V, and 1.2 V.

Application Scenarios
