The MPC5775B and MPC5775E microcontrollers target automotive and industrial battery management and inverter applications that require advanced performance, security, and ASIL-D support.
These MCUs are compatible with the MPC5777C device and offer customers an optimized feature set for the targeted applications. The MPC5775B and MPC5775E provide an ideal migration path for customers using MPC5xx, MPC55xx, MPC5644A and MPC5674F with eTPU timer and similar pin count options.
MPC5775BE主要特性:
• Three dual issue,32-bit CPU core complexes(e200z7),two of which run in lockstep
• Power Architecture embedded specification compliance
• Instruction set enhancement allowing variable length encoding (VLE), optionalencoding of mixed 16-bit and 32-bit instructions, for code size footprintreduction
• On the two computational cores: Signal processing extension (SPE1.1)instruction support for digital signal processing (DSP)
• Single-precision floating point operations
• On the two computational cores: 16 KB I-Cache and 16 KB D-Cache
• Hardware cache coherency between cores
• 16 hardware semaphores
• 3-channel CRC module
• 4 MB on-chip flash memory
• Supports read during program and erase operations, and multiple blocksallowing EEPROM emulation
• 512 KB on-chip general-purpose ...
