The MPC5534 is currently the entry level part for the MPC5500 family. Running at 80MHz, the MPC5534 features 1MB of flash memory which is automotive qualified flash with Read While Write (RWW) capability and has Error Code Correction (ECC) for added system protection. The 78.5kB Data SRAM also features ECC protection. The MPC5534 features one enhanced 32 channel Timer Processing Unit (eTPU) and is supported with 14.5K dedicated SRAM. The eTPU can act effectively as a co-processor performing tasks and functions with no intervention from the CPU required.  It is ideal for performing complex timing and control functions. In addition to the eTPU there is a 24-channel enhanced modular I/O system (eMOIS), which can not operate without the CPU, intended for complex control and timing functions. The MPC5534 has a set of control modules for connection to peripherals and networks. The four FlexCAN modules on board connect to CAN networks, while the two Serial Communications Interfaces connect to external serial peripherals. The 3 SPI ports have DMA support so they can send data straight to memory with no need to interrupt the CPU, the acronym for this module is DSPI.
