The STMicroelectronics SPC584Gx, SPC58EGx, SPC58NGx microcontroller belongs to a family of devices superseding the SPC56x family. SPC584Gx, SPC58EGx, SPC58NGx build on the legacy of the SPC5x family, while introducing new features coupled with higher throughput to provide substantial reduction of cost per feature and significant power and performance improvement (MIPS per mW). It has core frequency as high as 180 MHz. High performance e200z4 triple core:
32-bit Power Architecture technology CPU
Variable Length Encoding (VLE)
1 interrupt controller (INTC)
One CPU channel in lockstep
