E2v has revealed plans to support Qorivva microcontrollers with the release of hi-rel versions. The PC5674F is design deliver the next generation of avionic processing elements, high computing performance with minimal power consumption.

The PC5674F is based on a Power Architecture e200z7 core that runs up to 264MHz and embeds advanced features such as a Single Instruction Multiple Data (SIMD) capable Floating Point Unit (FPU) for digital signal processing, a 32 entry Memory Management Unit (MMU) and a 32KB L1 cache. The PC5674F features the eTPU2 time processor unit, an advanced programmable I/O controller that allows the processor to perform complex timing and I/O management independently from the core. In addition, PC5674F offers several communication interfaces, including FlexCAN, eSCI, DSPI, as well as an External Bus Interface (EBI).

This high-end microcontroller also features 4MB of on-chip flash memory with Error Correction Code (ECC), reducing PCB footprint and complexity. An integrated 64 channels Quad 12bit ADC allows the PC5674F to receive signals directly from sensors, eliminating the need for some analogue components on the board.

E2v's latest microcontroller is designed for airborne platforms, embedding memory and analogue functions and enabling significant board footprint savings. The availability of an extended reliability version of the PC5674F also allows room for innovating by embedding computing elements closer to the actuators which are exposed to harsh environments, enhancing the performance of the system while reducing cable weight. The PC5674F also represents a real path for improvement to all customers that are currently using legacy MPC555, MPC566, and MPC5554 on airborne platforms.

e2v will offer PC5674F in a 516-ball PBGA package with RoHS-compliant or leaded finish options. In addition to military temperature range availability (-55C to 125C), e2v also plans to develop a 150C high-temperature screened version of the processor for customers that will require temporary exposure to extreme environments.
