This compares a regular MPU design with a design based on RZ/A. The RZ/A design is much leaner, easier, and less prone to EMI. Designing with RZ/A1 is like getting the performance of a Microprocessor with the design simplicity of a Microcontroller. If a customer wants to keep their design simple, but get MPU class performance, this is just the part for them. With RZ/A1, users also get a lower BOM cost as shown in the two tables here. With a traditional MPU design on the left, they need to use expensive NOR Flash, DDR2 RAM, PMICs, and multi-layer PCBs. With the RZ/A1, designers can use a cheaper SPI Flash and they don’t need to procure and validate external RAM. This also helps limit the design to fewer PCB layers. The RZ/A1 uses just two voltage levels with no power sequencing requirements, so designers can use simple regulators instead of a PMIC. The end result will be customers seeing BOM cost savings and getting simple, robust, high performance designs with the Renesas RZ/A1.
