This expanded spectrum of scalable and compatible MCUs provides developers with numerous options for developing end products with a high degree of hardware and software reuse of engineering resources. With the addition of the new S128, S3A3, and S3A6 groups from Synergy MCUs, there are now a total of seven MCU groups with 57 devices based on ARM® Cortex®-M CPU cores, covering operating frequencies from 32MHz to 240MHz and on-chip flash memory of 64KB, 128KB, 256KB, 512KB, 1MB, 2MB, and 4MB.
 
The 20 new Synergy MCU devices are now ready to lead customers and will be available to the general market in June 2017.
 
Since its market introduction in October 2015, Synergy Platform's capabilities have grown in software with the expansion of the Synergy Software Package (SSP) and its unprecedented levels of software quality assurance, in partner solutions with more Verified Software Add-ons (VSAs), in software development tools with the addition of IAR Embedded Workbench® for Renesas Synergy™, in hardware with new Synergy Kits and more MCU devices that are fully accessible through the SSP's Application Programming Interface (API).

S128, S3A3, and S3A6 MCUs:
Developers of systems with lower requirements can select devices from the S3A3 and S3A6 groups to scale their applications up to 512 KB and 256 KB of flash memory as needed, compared to the existing 1 MB flash MCUs in the S3A7 group. The S128 group expands the selections for very low-power applications that require more memory, up to 256 KB, or require additional analog signal conditioning, compared to the existing S124 group MCUs.
