Renesas Synergy™ Development Kit DK-S3A7

The Renesas Synergy™ Development Kit DK-S3A7 is host to a Synergy S3 Series MCU from the S3A7 group, a super-efficient MCU because of its Arm® Cortex®-M4 CPU core with FPU running at moderate speed on an ultra-low power silicon process. The DK-S3A7 kit is engineered to allow you to harness and measure this efficiency while developing software for your end-product using the Synergy Platform.


The kit is comprised of two circuit boards, the upper board hosting the MCU and the lower board for signal expansion and implementation special functions, and to provide connectivity such as USB-FS host and device, CAN with PHY, and more.


The lower expansion board can be replaced with your own custom board for rapidly prototyping your specific end-product. A custom segment LCD glass module board is also included for initial evaluation and software development – and the LCD glass can be replaced with your own glass for specific end-product development. Take advantage of the large on-chip 1 MB Flash memory in the MCU and the extended serial Flash memory on the board connected by QSPI for LCD menus and text.


Provisions for precise power consumption measurements are there in the kit to give visibility of current used over the profile of your program execution.Expansion capability is designed into this kit with many connection points plus industry-standard Pmod™ connectors for attaching a variety of multi-function boards in the market, or for connecting custom boards.


With the purchase of a Renesas Synergy kit, access to the e² studio Integrated Solution Development Environment (ISDE) for Synergy MCU device and software configuration plus extensive code development and debugging using the Renesas Synergy Software Package (SSP) is included. In addition the complete IAR IDE Embedded Workbench for Synergy is included as well.



All Renesas Synergy development kits come with an industry standard high speed SEGGER J-Link OB debugger as well as an integrated Bluetooth® low energy (BLE) module.
